Abstract Vegetation is an underutilized medium for environmental DNA (eDNA) sampling. eDNA methods leveraging water as a substrate exclude application to many terrestrial species. The use of eDNA to detect small mammals can complement current survey approaches (live capturing, track plating, and camera trapping) while reducing risks to the animals....

Background Determining the life-history traits of extinct species is often difficult from skeletal remains alone, limiting the accuracy of studies modeling past ecosystems. However, the analysis of the degraded endogenous bacterial DNA present in paleontological fecal matter (coprolites) may enable the characterization of specific traits such as th...

Background: Salas y Gómez is a small, volcanic island largely untouched by humans due to its diminutive size and remoteness. Since the waters surrounding Salas y Gómez were established as Motu Motiro Hiva Marine Park in 2010, marine investigations have been the primary research focus. Secondarily, nesting seabird communities have been censused sinc...

The arthropod fauna of Salas y Gómez is essentially uncharacterized. Past biological inventory work was largely centered upon marine life and pelagic birds. We present the results of the most comprehensive terrestrial arthropod inventory of Salas y Gómez island to date. At least 16 morphospecies across 11 coarse taxonomic groups are now known. We a...

Precisely defining how animals disperse underground is an emerging area of cave ecology. Genetic analysis may be one of the best tools for increasing our understanding. While a species’ colonization of caves can spur allopatric speciation, mesocaverns can permit gene flow. Individuals of a subterranean-dwelling population may actively use these sma...

This study represents the first large scale cave biological inventory of caves in Sierra de las Nieves Natural Park, Andalucía, Spain. We sampled seven caves (three low and four high elevation caves) from 22 June through 01 July 2017. We have preliminarily identified at least 42 morphospecies and 13 coarse-level taxonomic groups (i.e., Order or hig...

Este trabajo representa el primer inventario, a gran escala, de la biología de las cuevas del Parque Natural de la Sierra de las Nieves, Andalucía, España. Se han muestreado siete cavidades, de las cuales tres se localizan a cota relativamente baja, a una altura media de unos 1000 m.s.n.m., mientras las otras cuatro se localizan a una cota relativa...

Project
This study represents the most comprehensive effort to characterize cave-dwelling arthropod communities in Parque Natural Sierra de las Nieves, Andalusia, southern Spain. We will inventory at least 20 caves by applying an improved systematic methodology for sampling cave-dwelling arthropods. Data from this work will: (1) be used to gain insight into regional patterns of cave biological diversity; (2) provide us with a framework for making predictions concerning future colonization events of surface dwelling species given climate change; and, (3) serve as a comparative dataset for better understanding landscape scale trends in community assembly and diversity in Western Europe.

Rapa Nui (Easter Island) has undergone extensive environmental change. Today, all native terrestrial vertebrates and most native plants have gone extinct. Today, the island ecosystem is dominated by a community of nonnative animals and plants. Insects are that remain of the endemic native fauna. By sampling caves, cliff faces, rocky and sandy shorelines and crater lake shorelines, we will increase the number of endemic insects known to the island.Through improving our knowledge of the extent of endemic insects on the island, we can better manage and protect them.
