Long-Term Monitoring of the Traditional Knowledge of Plant Species Used for Culinary Purposes in the Valencia Region, South-Eastern Spain

The aim of this study is to inventory and study ethnobotanical knowledge of edible plants in the Valencian Community (Spain). In respect to culinary uses, 92 species of plant were reported to be edible, finding the following uses: 58 raw, 52 cooked, 16 fried, 7 dried, 21 in liquors and beverages, 25 in dessert and sweets, 11 as seasoning, 17 in pickles, and 10 to curdle milk. We prepared a database that includes genus, family, scientific, and vernacular names in Spanish and Catalan for each plant. We also created a classification of nine edible uses and plant parts used, being Asteraceae (n = 18), Brassicaceae (n = 7), Chenopodiaceae (n = 6), and Rosaceae (n = 6) the families most characterized for gastronomic purposes. The species with the most elevated cultural importance (CI) values were Foeniculum vulgare (CI = 1.389), Cynara scolymus (CI = 1.374), Papaver rhoeas (CI = 1.211), Beta vulgaris (CI = 1.167), and Juglans regia (CI = 1.155). The most used parts were the leaves (71), flowers (25), and branches (19), while the least used were roots (9) and seeds (8). Traditional knowledge of these plants helps to preserve traditional cuisine, promote the local economy and, in several species, encourage their cultivation.

Early life investment in antlers and body growth reflects adult performance in roe deer population under supplementary feeding conditions

Recent research has challenged the idea that cervid antlers are such costly traits, supporting the assertion early-life antler investment is an honest signal of adult phenotypic quality. However, inferences were made based on antler measurements while growing (velvet) and thus, studies on fully-formed clean antlers are needed to avoid possible bias caused by the inter-individual variation in antler growth phenology. We studied a semi-captive population of European roe deer inhabiting a sub-Mediterranean area (Valsemana research station) and living under optimal conditions (ad libitum food supply and veterinary care). Based on repeated measurements taken from 146 individuals, we assessed whether allocation to secondary sexual traits during early life affected body mass or antler development during adulthood. Furthermore, we evaluated which body measurements better predicted future male quality. Additionally, using 488 individuals, we described age-class-specific variation in male body measurements and assessed the decline in antler size between adult and senescent stages (i.e. magnitude of senescence). Results agree with the assertion that there is no negative effect of a high investment in antler during early life on adult antler size or body mass, but we suggest the use of clean antlers as a more robust and reliable measure. The variables that better predicted body mass during adulthood were yearling body mass and body size at 6 months. Antler score between 10 and 18 months resulted in the best indicator of adult antler size. Finally, we support the idea that the magnitude of senescence in antler size is smaller in environments with higher resource availability during winter.

Differences in the composition of arbuscular mycorrhizal fungal communities promoted by different propagule forms from a Mediterranean shrubland

As it is well known, arbuscular mycorrhizal (AM) colonization can be initiated from the following three types of fungal propagules: spores, extraradical mycelium (ERM), and mycorrhizal root fragments harboring intraradical fungal structures. It has been shown that biomass allocation of AM fungi (AMF) among these three propagule types varies between fungal taxa, as also differs the ability of the different AMF propagule fractions to initiate new colonizations. In this study, the composition of the AMF community in the roots of rosemary (Rosmarinus officinalis L., a characteristic Mediterranean shrub), inoculated with the three different propagule types, was analyzed. Accordingly, cuttings from this species were inoculated with either AMF spores, ERM, or colonized roots extracted from a natural soil. The AMF diversity within the rosemary roots was characterized using terminal restriction fragment length polymorphism (T-RFLP) of the small subunit (SSU) rDNA region. The AMF community established in the rosemary plants was significantly different according to the type of propagule used as inoculum. AMF taxa differed in their ability to initiate new colonizations from each propagule type. Results suggest different colonization strategies for the different AMF families involved, Glomeraceae and Claroideoglomeraceae colonizing mainly from colonized roots whereas Pacisporaceae and Diversisporaceae from spores and ERM. This supports that AMF taxa show contrasting life-history strategies in terms of their ability to initiate new colonizations from the different propagule types. Further research to fully understand the colonization and dispersal abilities of AMF is essential for their rational use in ecosystem restoration programs.
