1. The effects of climate change may constitute a major threat factor for endemic and threatened species of invertebrates. A particularly dramatic case can be found in the Iberian Peninsula, because of its high rate of species diversity and endemism. We aim to evaluate the effects of climate change on the distribution of 36 endangered and...

The long-term geological stability of aquatic habitats has been demonstrated to be a determinant in the evolution of macroinvertebrate fauna, with species in running (lotic) waters having lower dispersal abilities, smaller ranges and higher gene flow between populations than species in standing (lentic) environments. Lotic species have been...

This paper deals with some Collembola from a cave at La Sierra de Grazalema (Málaga). In total, eight species of springtails were found. Two may represent new species but there is insufficient material available to prepare full descriptions (one species in the genus Ceratophysella, one in Hypogastrura), one species (Folsomides cf. ayllonensis)...

1. Bergmann's rule sensu lato, the ecogeographic pattern relating animals' body size with environmental temperature (or latitude), has been shown to be inconsistent among insect taxa. Body size clines remain largely unexplored in aquatic insects, which may show contrasting patterns to those found in terrestrial groups because of the...

We assessed the relative importance of human activity and environmental suitability as drivers of compositional dissimilarity of alien birds for 65 of the most populous cities of the Iberian Peninsula. We examined how these drivers relate to Zeta diversity (f) for alien Passeriformes and Psittaciformes. We performed the analysis using multiple...

High mountain areas are especially vulnerable to global warming, as they ex-perience faster temperature changes than lowlands in a climate change con-text. Notably, increased temperatures and frequency of extreme flooding anddroughts, and the consequent decrease in ice cover and water availability fluctua-tions, will induce important physical...

Elevation gradients provide powerful study systems for examining the influence of environmental filters in shaping species assemblages. High-mountain habitats host specific high-elevation assemblages, often comprising specialist species adapted to endure pronounced abiotic stress, while such harsh conditions prevent lowland species from...

Biodiversity conservation is a central imperative of the 21st century. Subterranean ecosystems deliver critical nature's contributions to people and harbour a broad diversity of poorly understood specialised organisms. However, the subterranean biome is still largely overlooked in global biodiversity targets. We assessed how well subterranean...

Here we focused on the co-occurrence pattern on regional and local scales, and on the niche differences of two species of congeneric beetles (Ochthebius quadricollis and O. lejolisii, Hydraenidae) exclusive of supratidal rockpools. Abundances of adults and larval stages from both species and environmental variables were obtained in 10 pools...

We present a dataset that assembles occurrence records of alien tetrapods (amphibians, reptiles, birds and mammals) in the Iberian Peninsula, a coherent biogeographically unit where introductions of alien species have occurred for millennia. These data have important potential applications for ecological research and management, including the...

1. Accurate assessments of species'vulnerability to climate change requireintegrated measurements of its different drivers, including extrinsic (the magnitude andrate of climate change) and intrinsic factors (organisms'sensitivity and adaptive capac-ity). According to these factors, aquatic insects restricted to alpine ponds may be espe-cially...
