Abstract
The main purpose of our paper is to document genus Hydropsyche (Trichoptera: Hydropsychidae) in northwestern Algeria and to provide the larval descriptions of the species set. Larvae, pupae, and imagines were collected from 14 sampling sites over a five-year period (2014-2019). Eight Hydropsyche species have been identified, with Hydropsyche siltalai being a new record for Algeria and North Africa, and Hydropsyche pellucidula a new record for Algeria. A comparison of our checklist with those of the Moroccan Rif and Europe is provided, as well as the geographical distribution of each species. This Algerian Hydropsyche species revision provides precise and reliable taxonomic characters for distinguishing larvae of the species, and a taxonomic key is proposed for their identification. In addition, information regarding their distribution is included.

DISPERSE, a trait database to assess the dispersal potential of European aquatic macroinvertebrates. Sci Data 2020; 7:386. [PMID: 33177529 PMCID: PMC7658241 DOI: 10.1038/s41597-020-00732-7] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Accepted: 10/21/2020] [Indexed: 11/09/2022] Open
Abstract
Dispersal is an essential process in population and community dynamics, but is difficult to measure in the field. In freshwater ecosystems, information on biological traits related to organisms' morphology, life history and behaviour provides useful dispersal proxies, but information remains scattered or unpublished for many taxa. We compiled information on multiple dispersal-related biological traits of European aquatic macroinvertebrates in a unique resource, the DISPERSE database. DISPERSE includes nine dispersal-related traits subdivided into 39 trait categories for 480 taxa, including Annelida, Mollusca, Platyhelminthes, and Arthropoda such as Crustacea and Insecta, generally at the genus level. Information within DISPERSE can be used to address fundamental research questions in metapopulation ecology, metacommunity ecology, macroecology and evolutionary ecology. Information on dispersal proxies can be applied to improve predictions of ecological responses to global change, and to inform improvements to biomonitoring, conservation and management strategies. The diverse sources used in DISPERSE complement existing trait databases by providing new information on dispersal traits, most of which would not otherwise be accessible to the scientific community.

The gut microbiota of brood parasite and host nestlings reared within the same environment: disentangling genetic and environmental effects. ISME JOURNAL 2020; 14:2691-2702.

Abstract
Gut microbiota are essential for host health and survival, but we are still far from understanding the processes involved in shaping their composition and evolution. Controlled experimental work under lab conditions as well as human studies pointed at environmental factors (i.e., diet) as the main determinant of the microbiota with little evidence of genetic effects, while comparative interspecific studies detected significant phylogenetic effects. Different species, however, also differ in diet, feeding behavior, and environmental characteristics of habitats, all of which also vary interspecifically, and, therefore, can potentially explain most of the detected phylogenetic patterns. Here, we take advantage of the reproductive strategy of avian brood parasites and investigate gut microbiotas (esophageal (food and saliva) and intestinal) of great spotted cuckoo (Clamator glandarius) and magpie (Pica pica) nestlings that grow in the same nests. We also estimated diet received by each nestling and explored its association with gut microbiota characteristics. Although esophageal microbiota of magpies and great spotted cuckoos raised within the same environment (nest) did not vary, the microbiota of cloacal samples showed clear interspecific differences. Moreover, diet of great spotted cuckoo and magpie nestlings explained the microbiota composition of esophageal samples, but not of cloaca samples. These results strongly suggest a genetic component determining the intestinal microbiota of host and parasitic bird species, indicating that interspecific differences in gut morphology and physiology are responsible for such interspecific differences.

Abstract
A partir de una exhaustiva revisión bibliográfica y de nuevos datos aportados en este estudio se establece que el número de especies de tricópteros registradas en Andalucía asciende a 136, incluidas en 53 géneros y 17 familias. Este número equivale aproximadamente al 38% de las especies presentes en la península ibérica. Catagapetus mclachlani y Oxyethira falcata constituyen nuevas citas para Andalucía, así como el género Beraea. Se confirma asimismo la presencia de Stenophylax permistus. Además se menciona una nueva especie de Hydropsyche, otra de Helicopsyche y una probable nueva especie del género Agapetus. Las familias mejor representadas son Hydroptilidade (18%), Limnephilidae (17%), Leptoceridae (13%) e Hydropsychidae (13%). Con esta actualización se han registrado 86 nuevas citas provinciales, mejorando sensiblemente los inventarios de las provincias de Granada, Jaén, Málaga y Sevilla. Los tricópteros de las provincias de Almería y especialmente los de Huelva, permanecen sin embargo muy poco estudiados. El estudio biogeográfico llevado a cabo entre las ocho unidades geográficas propuestas muestra tres grandes dominios diferenciados: Sierra Morena, el Sistema Bético y la depresión del Guadalquivir. Contrariamente a lo que se podría pensar, la tricopterofauna de las sierras Béticas húmedas (Serranía de Ronda y Campo de Gibraltar) parece mostrar una mayor similitud con la de Sierra Morena. La fauna de tricópteros andaluza está formada mayoritariamente por componentes de origen europeo (más del 50%) y endemismos (42%), de los que un 60% son exclusivos de Andalucía. Estos datos muestran que, dentro de la península ibérica, esta región destaca como una zona importante de refugio y centro de especiación para los tricópteros.

Abstract
DNA barcoding was intended as a means to provide species-level identifications through associating DNA sequences from unknown specimens to those from curated reference specimens. Although barcodes were not designed for phylogenetics, they can be beneficial to the completion of the Tree of Life. The barcode database for Trichoptera is relatively comprehensive, with data from every family, approximately two-thirds of the genera, and one-third of the described species. Most Trichoptera, as with most of life's species, have never been subjected to any formal phylogenetic analysis. Here, we present a phylogeny with over 16 000 unique haplotypes as a working hypothesis that can be updated as our estimates improve. We suggest a strategy of implementing constrained tree searches, which allow larger datasets to dictate the backbone phylogeny, while the barcode data fill out the tips of the tree. We also discuss how this phylogeny could be used to focus taxonomic attention on ambiguous species boundaries and hidden biodiversity. We suggest that systematists continue to differentiate between 'Barcode Index Numbers' (BINs) and 'species' that have been formally described. Each has utility, but they are not synonyms. We highlight examples of integrative taxonomy, using both barcodes and morphology for species description.This article is part of the themed issue 'From DNA barcodes to biomes'.

Does avian conspicuous colouration increase or reduce predation risk? Oecologia 2013; 173:83-93.

Abstract
Animals often announce their unprofitability to predators through conspicuous coloured signals. Here we tested whether the apparently conspicuous colour designs of the four European Coraciiformes and Upupiformes species may have evolved as aposematic signals, or whether instead they imply a cost in terms of predation risk. Because previous studies suggested that these species are unpalatable, we hypothesized that predators could avoid targeting them based on their colours. An experiment was performed where two artificial models of each bird species were exposed simultaneously to raptor predators, one painted so as to resemble the real colour design of these birds, and the other one painted using cryptic colours. Additionally, we used field data on the black kite's diet to compare the selection of these four species to that of other avian prey. Conspicuous models were attacked in equal or higher proportions than their cryptic counterparts, and the attack rate on the four species increased with their respective degree of contrast against natural backgrounds. The analysis of the predator's diet revealed that the two least attacked species were negatively selected in nature despite their abundance. Both conspicuous and cryptic models of one of the studied species (the hoopoe) received fewer attacks than cryptic models of the other three species, suggesting that predators may avoid this species for characteristics other than colour. Globally, our results suggest that the colour of coraciiforms and upupiforms does not function as an aposematic signal that advises predators of their unprofitability, but also that conspicuous colours may increase predation risk in some species, supporting thus the handicap hypothesis.

Abstract
Notalina roraima Holzenthal 1986 was described on the basis of a single holotype specimen from the Pantepui Region. The species is a member of the endemic Neotropical long-horned caddisfly (Trichoptera: Leptoceridae) subgenus Notalina (Neonotalina) Holzenthal 1986. We present new records of this species and describe some morphological variation in the male genitalia. Moreover, we describe and illustrate the larva of this species and include information of its habitat. We also differentiate it from N. morsei, the only larva of the subgenus Neonotalina described until now.

Ecological and historical filters constraining spatial caddisfly distribution in Mediterranean rivers. FRESHWATER BIOLOGY 2005; 50:781-797.

Abstract
1. Contemporary species distributions are determined by a mixture of ecological and historical filters acting on several spatial and temporal scales. Mediterranean climate areas are one of the world's biodiversity hotspots with a high level of endemicity, which is linked to complex ecological and historical factors. 2. This paper explores the ecological and historical factors constraining the distribution of caddisfly species on a large regional scale. A total of 69 taxa were collected from 140 sampling sites in 10 Iberian Mediterranean river basins. Approximately 74% of taxa can be considered rare, with the southern basins (the Baetic-Riffian region) having greater endemicity. The greatest richness, involving a mixture of northern and southern species, was found in the transitional area between the Baetic-Riffian region and the Hesperic Massif. 3. The historical processes occurring during the Tertiary (i.e. the junction of the Eurasian and African plates) explained 3.1% of species distribution, whereas ecological factors accounted for 20.7%. Only 0.3% was explained by the interaction of history and ecology. A set of multi-scale ecological variables (i.e. basin, reach and bedform characteristics) defined five river types with specific caddisfly assemblages. The commonest caddisfly species accounted for the regional distribution pattern, while rare taxa contributed to the explanation of subtle patterns not shown by common species. 4. Despite the importance of historical factors for biogeography and the large scale used in our study, ecological variables better explained caddisfly distribution. This may be explained by the length of time since the historical process we are considering, the high dispersion and colonisation capacity of many caddisfly species, and the strong environmental gradient in the area. Because of the historical and environmental complexity of Mediterranean areas, rare taxa should be included in ecological studies so that the singularity of these ecosystems is not missed.

Abstract
Caddisflies are a well represented group with high species diversity in Mediterranean climate rivers. Although they are widely used in water quality assessment, little is known of the ecological profiles of families or species. We present a simple score for ecological profiles which measures intolerance to water quality. The ecological profiles of caddisflies are diverse and the degree of tolerance at the family level is related to species diversity and the tolerance of individual species to water quality. Comparisons with the scores used in the biotic index IBMWP show general agreement between the degree of intolerance of a family and its score in the IBMWP, with few exceptions. Studies on tolerance are required to elucidate the autecology of taxa, and to develop biological indices, especially in areas with high species diversity.
