Ecology and co-existence of two endemic day gecko (Phelsuma) species in Seychelles native palm forest [PDF]
, 2011 In island ecosystems, reptiles play diverse ecological roles as a result of niche broadening, which increases potential niche overlap between species. Ecological niche partitioning is a means of reducing direct competition between coexisting species and ...

Genome size evolution of the extant lycophytes and ferns
Plant Diversity, 2022 Ferns and lycophytes have remarkably large genomes. However, little is known about how their genome size evolved in fern lineages. To explore the origins and evolution of chromosome numbers and genome size in ferns, we used flow cytometry to measure the ...

Habitat preference and the marine-speciation paradox [PDF]
Proceedings of the Royal Society of London. Series B: Biological Sciences, 2003 Marine organisms challenge the classical theories of local adaptation and speciation because their planktonic larvae have the potential to maintain high gene flow. The marine-speciation paradox is illustrated by contact zones between incipient species that are so large that allopatric divergence seems unlikely.

Relationships Between Habitat and Snag Characteristics and the Reproductive Success of the Brown-headed Nuthatch (Sitta pusilla) in Eastern Texas. [PDF]
, 2004 Habitat use and reproductive success of the Brown-headed Nuthatch (Sitta pusilla Latham) were studied in East Texas during the 2001-2002 breeding seasons. We compared nest cavity selection at used and randomly selected non-used areas.

Interspecific aggression and habitat partitioning in garter snakes. [PDF]
PLoS ONE, 2014 Defense of a limited resource, such as space or food, has recently been discovered in snakes and has been widely documented in lizards. Garter snakes (Thamnophis spp.) are historically considered generalist predators such that food is not a limiting ...

Bees use anthropogenic habitats despite strong natural habitat preferences [PDF]
Diversity and Distributions, 2018 Abstract Aim Habitat loss and alteration are widely considered one of the main drivers of current pollinator diversity loss. Yet little is known about habitat importance and preferences for major groups of pollinators, although this information is crucial to anticipate and mitigate the current ...
