Description and phylogenetic position of a new species of Oreobates (Anura: Craugastoridae) from northwestern Argentina
(Herpetologists League, 2014-06)
We describe a new species of Oreobates from Jujuy, Argentina. The new species is clearly diagnosable from other species of Oreobates by a combination of morphological characters and support by molecular evidence (genetic ...
Phylogenetic position of Argentinian and Chilean endemic species of Senecio ser. Culcitium (Asteraceae) with an evolutionary analysis of morphological characters
(Magnolia Press, 2019-01-09)
In its current circumscription, Senecio ser. Culcitium Cabrera, which includes ca. 40 South American species, is characterized by discoid, sometimes nodding capitula, calycular bracts resembling a multiseriate involucre, ...
Area and distance from mainland affect in different ways richness and phylogenetic diversity of snakes in Atlantic Forest coastal islands
(Wiley-Blackwell, 2019-04-01)
Aim The Theory of Island Biogeography posits that ecological and evolutionary processes regulate species richness of isolated areas. We assessed the influences of an island area and distance from the mainland on species ...
Landscape heterogeneity shapes bird phylogenetic responses at forest–matrix interfaces in Atlantic Forest, Brazil
(2021-03-01)
Agricultural intensification is one of the major factors driving biodiversity loss. However, most studies in human-dominated landscapes have used taxonomic diversity in their analysis, ignoring evolutionary relationships. ...
The community-level effect of light on germination timing in relation to seed mass: a source of regeneration niche differentiation
(Wiley-Blackwell, 2014-11-01)
Within a community, species may germinate at different times so as to mitigate competition and to take advantage of different aspects of the seasonal environment (temporal niche differentiation). We illustrated a hypothesis ...
Climatic niche at physiological and macroecological scales: the thermal tolerance–geographical range interface and niche dimensionality
(Oxford, 2014-04)
Under the Hutchinsonian concept of the realized niche, biotic interactions and dispersal limitation may prevent species from fully occupying areas that they could tolerate physiologically. This can hamper the translation ...
