Are Amphipod invaders a threat to the regional biodiversity? Conservation prospects for the Loire River [PDF]

, 2010
The impact of invasions on local biodiversity is well established, but their impact on regional biodiversity has so far been only sketchily documented.

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 ...

Microhabitat preferences of Maculinea teleius (Lepidoptera: Lycaenidae) in a mosaic landscape

European Journal of Entomology, 2007
The Scarce Large Blue (Maculinea teleius) is an endangered butterfly throughout Europe due to its special life-cycle and habitat loss. Our aims were to describe the microhabitats available to this butterfly, to test what factors influence the presence ...

Is scuba sampling a relevant method to study microhabitat in lakes? Examples and comparisons for three European species [PDF]

, 2001
We compared fish microhabitat use patterns in the littoral zone of a lake using a new direct method (i.e. Point Abundance Sampling by Scuba, PASS) and the widely used Point Abundance Sampling by Electrofishing technique (PASE).

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.

The role of glacier mice in the invertebrate colonisation of glacial surfaces: the moss balls of the Falljökull, Iceland [PDF]

, 2012
Glacier surfaces have a surprisingly complex ecology. Cryoconite holes contain diverse invertebrate communities while other invertebrates, such as Collembola often graze on algae and windblown dead organic on the glacier surface.

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 ...
