EL NIÑO EFFECTS ON THE DYNAMICS AND CONTROL OF ANISLAND ECOSYSTEM IN THE GULF OF CALIFORNIA
The tremendous increase in precipitation associated with the 1992-1993 El Nino profoundly affected terrestrial communities on arid islands in the Midriff region of the Gulf of California. In 1992,Expand
Stable isotopes reveal strong marine and El Niño effects on island food webs
Stable isotope analysis is a powerful tool for unravelling the complex structure of food webs. This technique is particularly well suited for studies at ecosystem boundaries, where physical processesExpand
Terrestrial arthropod fauna of arid areas of SE Spain: Diversity, biogeography, and conservation
TLDR
The fauna of the SE Iberian arid zones represents an important component of the high ecological diversity of the Mediterranean ecosystem in SE Spain, not only because of their arthropod diversity but also due to the important implications that these areas have for conservation in the entire SE region of the Iberia Peninsula. Expand
Dung-insect community composition in arid zones of south-eastern Spain
Dung-insect community composition was studied at three sites for 1 year, and for a further 8 months at one site, in an arid region of Spain. The insect community was dominated by ants, dung flies andExpand
Foraging of Buthus occitanus (Scorpiones: Buthidae) on shrub branches in an arid area of southeastern Spain
TLDR
Foraging of B. occitanus on shrubs may be favored if this behavior not only allows access to shrub-inhabiting prey, but also reduces predation risk. Expand
Analysis of Spatial and Seasonal Variability of Carrion Beetle (Coleoptera) Assemblages in Two Arid Zones of Spain
TLDR
Abiotic factors, competition, and predation contribute to the spatial and temporal variability of the carrion beetle assemblages, suggesting that environmental variations are important factors in the generally observed pattern of divergence in desert communities. Expand
A Revision of Craniotus Leconte (Coleoptera: Tenebrionidae: Pimeliinae: Asidini), with Descriptions of New Insular Species from Mexico and Notes on Distribution and Biology
TLDR
The genus Craniotus LeConte is revised and the following new species are introduced and placed as a synonym of C. pubescens: craniotus mardecortesi Aalbu, Smith, and Sanchez Piñero (Isla San Esteban, Baja California, Mexico). Expand
Diet of the ladybird spider Eresus kollari (Araneae: Eresidae) in an arid system of southeastern Spain
TLDR
The high proportion of large-size prey in the webs studied, especially tenebrionids, indicate that this spider has a diet similar to that of Latrodectus lilianae Melic, 2000 in the study area, but the different hunting techniques used by the two spiders probably account for the dissimilar proportion of ants and predacious arthropods in the two diets. Expand
Coprophagy in Lepidoptera: observational and experimental evidence in the pyralid moth Aglossa pinguinalis
TLDR
Coprophagy is reported as a main feeding habit for the larvae of another pyralid moth, Aglossa pinguinalis, on the basis of observational and experimental evidence, and it is hypothesized that coprophagous Lepidoptera will be restricted to competition- and predation-free habitats and resources, feeding on excrement inside caves and animal burrows.
