Microhabitat use by Phalloceros harpagos Lucinda (Cyprinodontiformes: Poeciliidae) from a coastal stream from Southeast Brazil

Neotropical Ichthyology
The size-related microhabitat use of Phalloceros harpagos Lucinda, 2008 from Mato Grosso stream (Saquarema - RJ) was examined. We analyzed, during 8.3 h of underwater observation, a 200 m long reach in the upper Mato Grosso stream, quantifying the ...

Ecomorphological Variation in Three Species of Cybotoid Anoles [PDF]

, 2017
© 2018 by The Herpetologists' League, Inc. Caribbean Anolis lizards exhibit a complex suite of ecological, morphological, and behavioral traits that allow their specialization to particular microhabitats. These microhabitat specialists, called ecomorphs,

Can environmental variation affect seedling survival of plants in northeastern Mexico? [PDF]

Archives of Biological Sciences, 2011
The effects of global warming increase the frequency and intensity of many climate events such as rainfall. We evaluated the effects of environmental conditions on early stage seedling survival of the native thorn scrub species Caesalpinia mexicana A.

Parasite-mediated microhabitat segregation between congeneric hosts [PDF]

Biology Letters, 2018
Parasite-mediated competition can shape community structure and host distribution. If two species compete for resources, parasites may indirectly change the outcome of competition. We tested the role of a trematode parasite in mediating microhabitat use by congeneric isopods Austridotea annectens and ...

Microhabitat niche partitioning associated with hybridization among sympatric Ixora species in a tropical rainforest

Global Ecology and Conservation
Tropical rainforests exhibit remarkable plant diversity, including many congeneric species that coexist sympatrically within small spatial scales.

Niche divergence along a fine‐scale ecological gradient in sympatric color morphs of a coral reef fish

Ecosphere, 2018
Color polymorphisms offer unique opportunities for testing the role of ecological adaptation and natural selection in the origin of species. However, the ecological conditions that facilitate the coexistence and speciation of color morphs in nature ...

Habitat use by Astyanax taeniatus (Jenyns, 1842) (Characiformes: Characidae) in a coastal stream from Southeast Brazil

Neotropical Ichthyology
The habitat use of a stream-dwelling Astyanax taeniatus from the State of Rio de Janeiro was investigated. We performed 12 h of underwater observation in a 200 m long stretch in the upper Roncador stream and quantified the following microhabitat ...
