A large scale semi-quantitative biodiversity assessment was conducted in white oak woodlands areas included the Spanish Network of National Parks, as part a project aimed at revealing biogeographic patterns and identify drivers. The COBRA sampling protocol sixteen 1-ha plots across six national parks using nested design. All adult specimens were identified to species level based on morphology. Uncertain delimitations identifications due either limited information diagnostic characters or...
Molecular gut-content analysis has revolutionized the study of food webs and feeding interactions, allowing detection prey DNA within gut many organisms. However, successful is a challenging procedure in which factors affect every step, starting from extraction process. Spiders are liquid feeders with branched diverticula extending into their legs throughout prosoma, thus digestion takes places different parts body simple dissection not possible. In this study, we investigated differences...
Spiders are a highly diversified group of arthropods and play an important role in terrestrial ecosystems as ubiquitous predators, which makes them suitable to test variety eco-evolutionary hypotheses. For this purpose, knowledge diverse range species traits is required. Until now, data on spider have been scattered across thousands publications produced for over two centuries written languages. To facilitate access such data, we developed online database archiving accessing at global scale....
Amidst a global biodiversity crisis1, the word 'biodiversity' has become indispensable for conservation and management2. Yet, is often used as buzzword in scientific literature. Resonant titles of papers claiming to have studied 'global biodiversity' may be promote research focused on few taxonomic groups, habitats, or facets - taxonomic, (phylo)genetic, functional. This usage lead extrapolating results outside target systems these studies with direct consequences our understanding life...
The spider genus Dysdera Latreille is an excellent model for the study of evolution cave life: ten species are known to exist exclusively in subterranean environment Canary Islands, where has undergone local diversification. In present paper, two new troglobitic (Dysdera madai, sp. nov. and D. sibyllina, nov.) previously unknown sex five additional described illustrated: males gollumi Ribera & Arnedo, 1994, hernandezi Arnedo Ribera, 1999 labradaensis Wunderlich, 1991; females andamanae...
Unlike hexapods and vertebrates, in chelicerates, knowledge of the specific molecules involved chemoreception comes exclusively from comparative analysis genome sequences. Indeed, genomes mites, ticks spiders contain several genes encoding homologs some insect membrane receptors small soluble chemosensory proteins. Here, we conducted for first time a comprehensive RNA-Seq across different body structures chelicerate: nocturnal wandering hunter spider Dysdera silvatica Schmidt 1981....
En Canarias el medio subterráneo terrestre habitable ocupa una elevada proporción del terreno e incluye hábitats diversos como los tubos de lava y otros tipos cavidades volcánicas, la red profunda grietas, superficial o campos piroclastos. Su extensión frecuente interconexión permite presencia gran diversidad especies adaptadas a este (troglobiontes). Todas las arañas troglobiontes encontradas son endemismos canarios cada isla, excepción Lanzarote, tiene sus propias especies. Tras...
There is an increasing demand for databases including species trait information biodiversity and community ecology studies. The existence of useful comparative studies within taxa or geographical regions, but there low availability certain organisms. Here we present open access functional database spiders from Macaronesia the Iberian Peninsula, recording several morphological ecological traits related to life histories, microhabitat trophic preferences.We a that includes 12 biological 506...
The coexistence of multiple eco-phenotypes in independently assembled communities makes island adaptive radiations the ideal framework to test convergence and parallelism evolution. In radiation spider genus Dysdera Canary Islands, species diversification occurs concomitant with repeated events trophic specialization. These dietary shifts, feed primarily on woodlice, are accompanied by modifications morphology (mostly mouthparts), behaviour nutritional physiology. To gain insight into...
The ground-dweller spider genus Dysdera shows very high species richness on the oceanic archipelago of Canary Islands, providing one most outstanding examples island radiation among spiders, only paralleled by Tetragnatha spiders Hawaiian archipelago. A georeferenced database 48 occurring in Islands was assembled to facilitate ongoing and future research this remarkable lineage. All are endemic except for cosmopolitan crocata. dataset consists 794 distributional records documented from 1971...
Phylogenetic relatedness is a key diversity measure for the analysis and understanding of how species communities evolve across time space. Understanding nonrandom loss with respect to phylogeny also essential better-informed conservation decisions. However, several factors are known influence phylogenetic reconstruction and, ultimately, metrics. In this study, we empirically tested some these (topological constraint, taxon sampling, genetic markers calibration) affect resolution...
Long-term erosion and subsidence cause dramatic alterations in the physical ecological features of oceanic islands. Although islands have been extensively used as models for study speciation, little attention has given to investigating evolutionary patterns old volcanic that suffered severe climatic degradation. The spider genus Dysdera diversified across Canary Islands evolved endemisms low-elevation, xeric eastern islands, which sharply contrast with younger, higher, more humid western A...
Geological processes and ecological adaptation are major drivers of diversification on oceanic islands. Although in these islands is often interpreted as resulting from dispersal or island hopping rather than vicariance, this may not be the case with complex geological histories. The Tenerife, Canary Islands, emerged late Miocene 3 precursor that were subsequently connected reisolated by volcanic cycles. spider Dysdera verneaui endemic to where it widely distributed throughout most habitats,...
A main goal of ecological and evolutionary biology is understanding predicting interactions between populations both abiotic biotic environments, the spatial temporal variation these interactions, effects on population dynamics performance. Trait-based approaches can help to model generate a comprehensive ecosystem functioning. central tool collation databases that include species trait information. Such centralized have been set up for number organismal groups but lacking one most important...
The development of molecular techniques as a taxonomic tool and their integration with information provided by other disciplines, has enhanced species discovery, facilitated delimitation produced invaluable data for inferring phylogenies. Here, we provide an example how DNA sequence data, together morphometric, distributional ecological information, assist in identifying diagnosing previously overlooked lineages. nocturnal, ground-dwelling spider genus Dysdera colonized all the Macaronesian...
The relationship between species local abundance and their regional distribution (occupancy) is one of the most extensively recognized investigated patterns in ecology. While exceptions exist, generally held model that locally abundant also tend to be more widespread geographically. However, there only a limited understanding both mechanisms driving this relationship, scale dependency. Here we use occupancy data for 123 spider from across Canary Islands understand how dispersal ability niche...
Abstract The Eastern Canary Islands are the emerged tips of a continuous volcanic ridge running parallel to northeastern African coast, originated by episodic eruptions that can be traced back Miocene and that, following major period quiescence erosion, continued from Pliocene present day. islands have been periodically connected eustatic sea‐level changes resulting Pleistocene glacial cycles. ground‐dwelling spider Dysdera lancerotensis Simon, 1907 occurs along entire ridge, except on...
Abstract The spider genus D ysdera is considered to comprise specialist isopod feeders, although the degree of specialization varies between species, depending on morphological (shape chelicerae), behavioural (attack tactics) and metabolic (food quality prey) adaptations. has radiated extensively in C anary I slands (currently 47 endemic species are described) codistributed have different cheliceral shapes body sizes indicating feeding niches. In present study, we investigate existence...
Here we present the data obtained from samples collected as part of a large research project (MACDIV) which aims at understanding drivers spider (Araneae) community assembly in Macaronesian islands. To obtain data, applied sampling protocol COBRA (Conservation Oriented Biodiversity Rapid Assessment), twelve 50 m x native forest plots and five dry habitat on island Madeiraand 5 Porto Santo.

Natural selection plays a key role in deterministic evolution, as clearly illustrated by the multiple cases of repeated evolution ecomorphological characters observed adaptive radiations. Unlike most spiders, Dysdera species display high variability cheliceral morphologies, which has been suggested to reflect different levels specialization feed on isopods. In this study, we integrate geometric morphometrics and experimental trials with fully resolved phylogeny highly diverse endemic from...
