A new species of the genus Antarctobius Fairmaire (1885) from Islas Malvinas (Falkland Islands) is described and illustrated: A. malvinensis Posadas and Morrone n. sp. (type locality: East Falkland, Mt. Usborne). A key to ...

Parsimony analysis of endemicity (PAE) was used to analyse the distributional patterns of 124 species of Mexican gymnosperms, using two different sample units: gridcells and biogeographical provinces. PAE analyses were ...

a second one that includes southern Mexico and northern Central America a third one that includes the mountains in northwestern South America

The integration of biological and chemical data has provided patterns to identify three new Dysidea species from the Gulf of California (Pacific Ocean, Mexico). These three species are differentiated by distinctive ...

The study of the ecological and evolutionary consequences of clonal growth in vascular plants has been widely addressed

We investigate the evolutionary history of the wide-ranging Nearctic treefrog Hyla arenicolor through the integration of extensive range-wide sampling, phylogenetic analyses of multilocus genetic data, and divergence dating. ...

and (ii) the derived state of the breeding (rather than winter) ecological niches of each species.

In 1950, Tinbergen described the elicitation of offspring begging by the red spot on the bill of parent gulls, and this became a model system for behavioural studies. Current knowledge on colour traits suggests they can ...
