In this paper a new species of fossil ground-beetle, Coptodera elektra n. sp. (Coleoptera: Carabidae) preserved in a piece of Baltic amber (Eocene) is described and the paleobiology of the species is studied. This new species represents the first known fossil record for the genus, as well as the first record of its presence in Europe.

Limodromus emetikos sp. n. (Coleoptera: Carabidae) is described and illustrated from Baltic amber (Eocene). Based on its morphological features, the new species is considered a sister taxon of the extant Holarctic assimilis species group. Furthermore, the specimen described here could represent a case of stress-triggered regurgitation, which would...

Under classical point of view, the formation of the Panama Isthmus during Pliocene (3 Ma ago) would have allowed the species interchange between North America and South America. This ecological and evolutionary process named Great American Biotic Interchange (GABI) would be determinant in the configuration of the current american biota. This proces...

Few studies have inquired about the relationship between myrmecological activity and the granulometry and mineralogy of sediments of a palaeontological site. The objectives of this article are to determine the sedi-mentological or mineralogical distinctions produced by ants of the species Messor barbarus when excavating their nests and extracting g...

The resource-use hypothesis developed by Vrba predicts that specialist species have higher speciation and extinction rates than generalist ones, due to their higher susceptibility to resource restriction, which makes them more sensitive to environmental change, vicariance and directional selection. Here, we present the first test of the resource-us...

Biomes are climatically and biotically distinctive macroecological units that formed over geological time scales. Their features consolidate them as ‘evolutionary scenarios’, with their own diversification dynamics. Under the concept of phylogenetic niche conservatism, we assessed, for the first time, the evolution of biome occupation in birds. We...

Ecological Niche Models (ENM), the set of different algorithms and workflows designed to obtain hypothetical maps of species, have been broadly used in studies on current biogeography, macroecology and conservation biology. The field experienced hot methodological debates around 10 years ago, when researchers tested the accuracy of the different al...

Los cambios climáticos de los últimos millones de años han tenido un efecto directo en los sucesivos procesos de expansión, contracción y fragmentación de los biomas a escala global. Estas modificaciones en la distribución y configuración de los biomas han influido notablemente en la evolución de las más de 5000 especies actuales de mamíferos terre...

The resource‐use hypothesis, proposed by E.S. Vrba, states that habitat fragmentation caused by climatic oscillations would affect particularly biome specialists (species inhabiting only one biome), which might show higher speciation and extinction rates than biome generalists. If true, lineages would accumulate biome‐specialist species. This effec...

Elisabeth S. Vrba’s resource-use hypothesis suggests that speciation in biomes subjected to successive expansion-contraction-fragmentation during periods of climatic change generates high frequency of species restricted to a single biome (stenobiomic species). We compiled biome occupation for all terrestrial mammals and, using Monte Carlo simulatio...

Este trabajo se centra en la recopilación de estudios sobre el comportamiento geofágico en el reino animal como un primer paso para su extrapolación al registro fósil. La geofagia, entendida desde el punto de vista del aprovechamiento químico del suelo por parte de animales, tiene finalidades tanto medicinales como reproductivas y ha sido observada...

Ground beetles (Coleoptera: Adephaga: Carabidae) constitute a large, cosmopolitan and highly diverse group within Coleoptera. With more than 34,000 known extant species, it is a group widely studied from taxonomic, systematic and ecological views, as well as broadly used as bioindicators of terrestrial environments. This stage of knowledge contrast...

La mirmecofagia supone una especialización dentro de la dieta insectívora consistente en un consumo exclusivo o mayoritario de hormigas y/o termitas. Esta especialización trófica ha aparecido en diversos grupos de mamíferos no emparentados directamente entre ellos, unida a adaptaciones muy específicas, dando lugar a un modelo mirmecófago muy estudi...
