Bat diversity boosts ecosystem services: Evidence from pine processionary moth predation. THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 912:169387. [PMID: 38110100 DOI: 10.1016/j.scitotenv.2023.169387] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 12/12/2023] [Accepted: 12/12/2023] [Indexed: 12/20/2023]
Abstract
Coniferous forests contribute to the European economy; however, they have experienced a decline since the late 1990s due to an invasive pest known as the pine processionary moth, Thaumetopoea pityocampa. The impacts of this pest are increasingly exacerbated by climate change. Traditional control strategies involving pesticides have had negative effects on public health and the environment. Instead, forest managers seek a more ecological and sustainable approach to management that promotes the natural actions of pest control agents. This study aims to evaluate the role of bats in suppressing pine processionary moths in pine forests and examine how the bat community composition and abundance influence pest consumption. Bats were sampled in the mountainous environment of the Serra da Estrela in central Portugal to collect faecal samples for DNA meta-barcoding analysis. We assessed the relationship between a) bat richness, b) bat relative abundance, c) bat diet richness, and the frequency of pine processionary moth consumption. Our findings indicate that sites with the highest bat species richness and abundance exhibit the highest levels of pine processionary moth consumption. The intensity of pine processionary moth consumption is independent of insect diversity within the site. The highest occurrence of pine processionary moth presence in bat diets is primarily observed in species that forage in cluttered habitats. A typical predator of pine processionary moths among bats is likely to be a forest-dwelling species that specialises in consuming Lepidoptera. These species primarily use short-range echolocation calls, which are relatively inaudible to tympanate moths, suitable for locating prey in cluttered environments, employing a gleaning hunting strategy. Examples include species from the genera Plecotus, Myotis, and Rhinolophus. This study enhances our understanding of the potential pest consumption services provided by bats in pine forests. The insights gained from this research can inform integrated pest management practices in forestry.

Abstract
The transport of passively dispersed organisms across tropical margins remains poorly understood. Hypotheses of oceanographic transportation potential lack testing with large scale empirical data. To address this gap, we used the seagrass species, Halodule wrightii, which is unique in spanning the entire tropical Atlantic. We tested the hypothesis that genetic differentiation estimated across its large-scale biogeographic range can be predicted by simulated oceanographic transport. The alternative hypothesis posits that dispersal is independent of ocean currents, such as transport by grazers. We compared empirical genetic estimates and modelled predictions of dispersal along the distribution of H. wrightii. We genotyped eight microsatellite loci on 19 populations distributed across Atlantic Africa, Gulf of Mexico, Caribbean, Brazil and developed a biophysical model with high-resolution ocean currents. Genetic data revealed low gene flow and highest differentiation between (1) the Gulf of Mexico and two other regions: (2) Caribbean-Brazil and (3) Atlantic Africa. These two were more genetically similar despite separation by an ocean. The biophysical model indicated low or no probability of passive dispersal among populations and did not match the empirical genetic data. The results support the alternative hypothesis of a role for active dispersal vectors like grazers.

From ecological functions to ecosystem services: linking coastal lagoons biodiversity with human well-being. HYDROBIOLOGIA 2023; 850:2611-2653. [PMID: 37323646 PMCID: PMC10000397 DOI: 10.1007/s10750-023-05171-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/29/2022] [Revised: 02/03/2023] [Accepted: 02/09/2023] [Indexed: 06/17/2023]
Abstract
In this review we highlight the relevance of biodiversity that inhabit coastal lagoons, emphasizing how species functions foster processes and services associated with this ecosystem. We identified 26 ecosystem services underpinned by ecological functions performed by bacteria and other microbial organisms, zooplankton, polychaetae worms, mollusks, macro-crustaceans, fishes, birds, and aquatic mammals. These groups present high functional redundancy but perform complementary functions that result in distinct ecosystem processes. Because coastal lagoons are located in the interface between freshwater, marine and terrestrial ecosystems, the ecosystem services provided by the biodiversity surpass the lagoon itself and benefit society in a wider spatial and historical context. The species loss in coastal lagoons due to multiple human-driven impacts affects the ecosystem functioning, influencing negatively the provision of all categories of services (i.e., supporting, regulating, provisioning and cultural). Because animals' assemblages have unequal spatial and temporal distribution in coastal lagoons, it is necessary to adopt ecosystem-level management plans to protect habitat heterogeneity and its biodiversity, ensuring the provision of services for human well-being to multi-actors in the coastal zone.

Major loss of coralline algal diversity in response to ocean acidification. GLOBAL CHANGE BIOLOGY 2021; 27:4785-4798.

Abstract
Calcified coralline algae are ecologically important in rocky habitats in the marine photic zone worldwide and there is growing concern that ocean acidification will severely impact them. Laboratory studies of these algae in simulated ocean acidification conditions have revealed wide variability in growth, photosynthesis and calcification responses, making it difficult to assess their future biodiversity, abundance and contribution to ecosystem function. Here, we apply molecular systematic tools to assess the impact of natural gradients in seawater carbonate chemistry on the biodiversity of coralline algae in the Mediterranean and the NW Pacific, link this to their evolutionary history and evaluate their potential future biodiversity and abundance. We found a decrease in the taxonomic diversity of coralline algae with increasing acidification with more than half of the species lost in high pCO2 conditions. Sporolithales is the oldest order (Lower Cretaceous) and diversified when ocean chemistry favoured low Mg calcite deposition; it is less diverse today and was the most sensitive to ocean acidification. Corallinales were also reduced in cover and diversity but several species survived at high pCO2 ; it is the most recent order of coralline algae and originated when ocean chemistry favoured aragonite and high Mg calcite deposition. The sharp decline in cover and thickness of coralline algal carbonate deposits at high pCO2 highlighted their lower fitness in response to ocean acidification. Reductions in CO2 emissions are needed to limit the risk of losing coralline algal diversity.

Global warming assessment suggests the endemic Brazilian kelp beds to be an endangered ecosystem. MARINE ENVIRONMENTAL RESEARCH 2021; 168:105307. [PMID: 33984550 DOI: 10.1016/j.marenvres.2021.105307] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Revised: 03/01/2021] [Accepted: 03/11/2021] [Indexed: 06/12/2023]
Abstract
Kelps are canopy-forming brown seaweed sustaining critical ecosystem services in coastal habitats, including shelter, nursery grounds, and providing food resources to a myriad of associated species. This study modeled the fundamental niche of Laminaria abyssalis along the Brazilian continental margin, an endemic species of the South Atlantic, to anticipate potential distributional range shifts under two contrasting scenarios of future environmental changes (RCP2.6 and RCP8.5). The model for fundamental niche predictions considering the "present scenario" has shown a wider potential area than the realized niche (i.e., the area where the species actually occurs) along the Brazilian coast. In both future scenarios, the models have shown niche erosion on the northern portion of the Brazilian coast and niche gains towards the south. In both scenarios, L. abyssalis populations tend to shift to deeper regions of the reef. The restricted range of occurrence (33,000 km2), intense anthropic activities along these beds (e.g., trawling fisheries, oil/gas mining, or removal for agricultural purposes) acting synergically with global warming, may drive this ecosystem to collapse faster than kelp species' ability to adapt. We propose to classify L. abyssalis as Endangered - (EN) under IUCN criteria, and highlight that long-term monitoring of kelp beds is an urgent need to develop effective conservation initiatives to protect such rare and invaluable ecosystem.

Decadal losses of canopy-forming algae along the warm temperate coastline of Brazil. GLOBAL CHANGE BIOLOGY 2020; 26:1446-1457. [PMID: 31833116 DOI: 10.1111/gcb.14956] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/27/2019] [Revised: 10/28/2019] [Accepted: 11/25/2019] [Indexed: 06/10/2023]
Abstract
The loss of canopy-forming seaweeds from urbanized coasts has intensified in response to warming seas and non-climatic pressures such as population growth and declining water quality. Surprisingly, there has been little information on the extent of historical losses in the South-western Atlantic, which limits our ability to place this large marine ecosystem in a global context. Here, we use meta-analysis to examine long-term (1969-2017) changes to the cover and biomass of Sargassum spp. and structurally simple algal turfs along more than 1,000 kilometres of Brazil's warm temperate coastline. Analysis revealed major declines in canopy cover that were independent of season (i.e., displaying similar trends for both summer and winter) but varied with coastal environmental setting, whereby sheltered bays experienced greater losses than coastal locations. On average, covers of Sargassum spp. declined by 2.6% per year, to show overall losses of 52% since records began (ranging from 20% to 89%). This contrasted with increases in the cover of filamentous turfs (24% over the last 27 years) which are known to proliferate along human-impacted coasts. To test the relative influence of climatic versus non-climatic factors as drivers of this apparent canopy-to-turf shift, we examined how well regional warming trends (decadal changes to sea surface temperature) and local proxies of coastal urbanization (population density, thermal pollution, turbidity and nutrient inputs) were able to predict the changes in seaweed communities. Our results revealed that the most pronounced canopy losses over the past 50 years were at sites exhibiting the greatest degree of coastal warming, the highest population growth and those located in semi-enclosed sheltered bays. These findings contribute knowledge on the drivers of canopy loss in the South-western Atlantic and join with global efforts to understand and mitigate declines of marine keystone species.

Abstract
Children may benefit from minimally invasive surgery (MIS) in the correction of Morgagni hernia (MH). The present study aims to evaluate the outcome of MIS through a multicenter study. National institutions that use MIS in the treatment of MH were included. Demographic, clinical and operative data were analyzed. Thirteen patients with MH (6 males) were operated using similar MIS technique (percutaneous stitches) at a mean age of 22.2±18.3 months. Six patients had chromosomopathies (46%), five with Down syndrome (39%). Respiratory complaints were the most common presentation (54%). Surgery lasted 95±23min. In none of the patients was the hernia sac removed; prosthesis was never used. In the immediate post-operative period, 4 patients (36%) were admitted to intensive care unit (all with Down syndrome); all patients started enteral feeds within the first 24h. With a mean follow-up of 56±16.6 months, there were two recurrences (18%) at the same institution, one of which was repaired with an absorbable suture; both with Down syndrome. The application of MIS in the MH repair is effective even in the presence of comorbidities such as Down syndrome; the latter influences the immediate postoperative recovery and possibly the recurrence rate. Removal of hernia sac does not seem necessary. Non-absorbable sutures may be more appropriate.

Abstract
BACKGROUND Whether myocardial ischaemia is the mechanism underlying chest pain in patients with angina and normal coronary arteriograms is controversial. We sought to detect the presence of transient myocardial ischaemia using continuous monitoring of coronary sinus blood pH during atrial pacing. METHODS AND RESULTS We studied 14 patients (eight women, six men, mean age 51 +/- 3 years) with typical exertional angina and normal coronary arteriograms and nine patients with coronary artery disease (two men, seven women, mean age 61 +/- 7 years). Of the 14 patients with normal coronary arteries, eight had a reduced coronary blood flow reserve (< 2.5-fold increase), 11 had an ischaemic-appearing response to exercise testing, six had reversible perfusion detects on exercise thallium scans and one had resting left bundle branch block. All patients underwent continuous pH monitoring of coronary sinus blood at rest and during incremental atrial pacing (up to 160 bpm). Coronary sinus oxygen saturation and myocardial lactate extraction ratio were also evaluated at rest and at peak pacing. Eleven patients with angina and normal coronary arteries and eight with coronary artery disease had angina during pacing. Both patients with angina and normal coronary arteries (n = 13) and patients with coronary artery disease (n = 9) showed a fall in coronary sinus pH (-0.02 +/- 0.02 vs -0.11 +/- 0.03 pH units, respectively, P < 0.01). Coronary sinus oxygen saturation expressed as a percentage dropped by 19 +/- 6% in patients with coronary artery disease and by 6 +/- 2% in patients with angina and normal coronary arteriograms (P < 0.05). Myocardial lactate extraction ratio decreased from 33 +/- 6% to -1.4 +/- 4% in patients with coronary artery disease and from 23 +/- 8% to 20 +/- 8% in those with angina and normal coronary arteriograms. Three patients with angina and normal coronary arteries had a drop in coronary sinus pH > 0.02 pH units (-0.043 +/- 0.006 pH units) and in coronary sinus oxygen saturation > 8% (16 +/- 3%) consistent with myocardial ischaemia. CONCLUSION Despite severe chest pain and reduced coronary flow reserve after pacing, most patients with angina and normal coronary arteriograms do not show metabolic evidence of myocardial ischaemia.

Abstract
The authors illustrate a case of right neonatal congenital diaphragmatic hernia (CDH) of Bochdalek with major pulmonary hypoplasia and postoperative massive mediastinal displacement to the right, leading to tracheal compression and recurrent respiratory distress at every attempt to wean the infant from the ventilator. Mediastinal stabilization was obtained by placing an expansion prosthesis (of the cutaneous type) in the right hemithorax, to prevent mediastinal obstruction of the main airways. This procedure may prove to be an original and efficient solution for the critical postoperative respiratory obstruction due to severe pulmonary hypoplasia and mediastinal mass effect in the newborn with CDH. However, this may not prevent progressive scoliosis, a serious problem frequently seen in the absence of one lung.

Abstract
BACKGROUND Continuous intravenous administration of adenosine to humans often results in a paradoxical rise in pulmonary capillary wedge pressure (PCWP), whereas arterial resistance is lowered and cardiac output and heart rate increase. This is believed to be due to diastolic stiffening of the ventricle or to a negative inotropic effect. In the present study, we tested these and other mechanisms by using pressure-volume (PV) analysis and echocardiography. METHODS AND RESULTS Fifteen patients with normal rest left ventricular function underwent cardiac catheterization and received adenosine at a rate of 140 micrograms/kg per minute IV for 6 to 10 minutes. PV relations were measured in 9 patients (without coronary artery disease) using the conductance catheter method. In 6 additional patients with coronary artery disease, echocardiograms were used to assess wall thickness and function, and aortic and coronary sinus blood, lactate, oxygen, and adenosine levels were measured. Adenosine increased PCWP by 19% (+2.6 mm Hg) in both patient groups while lowering arterial load by 30% and increasing cardiac output by 45% (all P < .001). There was no significant effect of adenosine on mean linear chamber compliance or monoexponential elastic stiffness, as the diastolic PV relation was unchanged in most patients. Diastolic wall thickness also was unaltered. Thus, the PCWP rise did not appear to be due to diastolic stiffening. Adenosine induced a rightward shift of the end-systolic PV relation (ESPVR) (+12.7 +/- 3.7 mL) without a slope change. This shift likely reflected effects of afterload reduction, as other indexes (stroke work-end-diastolic volume relation and dP/dtmax at matched preload) were either unchanged or increased. Furthermore, this modest shift in ESPVR was more than compensated for by vasodilation and tachycardia, so reduced systolic function could not explain the increase in PCWP. There also was no net lactate production to suggest ischemia. Rather than arising from direct myocardial effects, PCWP elevation was most easily explained by a change in vascular loading, as both left ventricular end-diastolic volume and right atrial pressure increased (P < .05). This suggests that adenosine induced a redistribution of blood volume toward the central thorax. CONCLUSIONS PCWP elevation in response to adenosine primarily results from changes in vascular loading rather than from direct effects on cardiac diastolic or systolic function.

Abstract
The authors report a case history of a male newborn at term, presenting with an accessory diaphragm in the right hemithorax, and an associated lung hypoplasia, revealed by a transient respiratory distress. The review of 31 cases published in the literature confirm the rare occurrence of this malformation. The diagnostic difficulties are discussed. The advantages of both MRI and CT scanning are compared. Pulmonary, vascular, or diaphragmatic abnormalities were due either to the isolated diagnosis or to its possible associated malformations. Operative management is often considered in view of the progressive respiratory complications. Excision of the accessory diaphragm does not necessarily solve the problem of a coexisting lung hypoplasia.

Abstract
PURPOSE To evaluate the success rate and complications, as well as the technical difficulties involved catheter laser coronary angioplasty, making evident the unsuccessful cases. METHODS Twenty eight patients were treated with laser from August to November, 1993. The treatment was complemented with balloon angioplasty. Lesions were complex: 10 (36%) were type B and 18 (64%), type C. Concerning the obstruction grade, 18 (64%) were > or = 95%. Laser generator CVX 300(TM) Spectranectics as well as Extreme(TM) and Vitesse(TM) catheters with 1.4, 1.7 and 2.0mm in diameter, concentric and excentric, were used. Laser procedure success was defined as a reduction > 20% in the obstruction grade. The procedure success was attended when the residual stenosis was < 50% after a 15-minute observation, after balloon complementation. RESULTS The unsuccess rate with laser catheter (Lc) was 34% (10 lesions) of which 3 cases were solved by other methods, 5 were not successful because of anatomic difficulties in surpassing the lesion and, in the two others the success criterium in the reduction of the obstruction grade of the coronary artery was not achieved, although the lesion surpassing was possible with the use of balloon catheter. The final success reached 89% (21 lesions). The procedure complications were a case of thrombosis, a perforation accompanied by a myocardial infarction and another myocardial infarction (non-Q wave), all with good outcome. CONCLUSION The use of laser in the treatment of coronary artery obstructive lesions is a viable method. Nonetheless, more experience is necessary to demonstrate its actual value, optimizate the results and may be reduce restenosis rate.

Abstract
PURPOSE To demonstrate the importance of the preservation of mitral annulus-chordae tendineae-papillary muscles continuity in mitral valve replacement. METHODS We studied 21 patients who were submitted to mitral valve replacement, divided in two randomized groups: group 1, 12 cases who undergone mitral valve replacement, with preservation of the posterior leaflet and correspondent chordae tendineae; and group 2-9 cases who undergone conventional mitral valve replacement, excising the mitral valve apparatus. The left ventricular function was studied both, in the pre and post operative period, by echocardiography, cardiac catheterization, and radioisotopic study. The statistical analysis was done by the Wilcoxson's test. RESULTS There were no early post operative deaths. Analyzing the results of the ejection fraction by the radioisotopic study we found a significant difference (p = 0.03) between the percentual decrease of the two groups. The results of the fractional shortening were higher in group 1 than in group 2, however not significant. The left ventricular diastolic diameters average was lower in group 1 than in group 2, so as the left atrium diameter. We found a decrease in left ventricular end-diastolic pressure in group 1, however there was an increase in group 2, by the cardiac catheterization. There was a proportional increase in group 1 both in lung artery and lung capillary pressures. There was a significant difference (p = 0.05) between the average values of right ventricular diastolic pressure. CONCLUSION There is better preservation of left ventricular function in group 1.
