Habitat-Based Predictions of Bridle Shiner (<i>Notropis bifrenatus</i>) in the Northeastern United States. [PDF]

open access: yesEcol Evol
We developed local and regional models for Maine and New Hampshire that may be used to focus bridle shiner (Notropis bifrenatus) surveys on areas with high predicted habitat suitability. This is significant because bridle shiners receive protection or concern status in thirteen states and two Canadian provinces: Limited data show that bridle shiners ...

Methods to Explore Changes in the Extent of Habitat Provided by <i>Ceratophyllum demersum</i> Shoots for Epiphytic Organisms in Changing Environments. [PDF]

open access: yesEcol Evol
Macrophytes, no information has yet been published on changes in their surface, that is, the extent of their habitat provided for epiphytic organisms. The aim of this paper was to (i) test the morphological diversity of C. demersum stands from various aquatic habitats, (ii) develop methods for accurate measurement, calculation, and simple estimation of

Habitat Complexity Reduces the Feeding Strength of Freshwater Predators. [PDF]

open access: yesEcol Evol
We investigated how habitat complexity influences the feeding responses of an ambush predator (Ischnura elegans) and a pursuit predator (Notonecta glauca) preying on Asellus aquaticus. Feeding rates of I. elegans were primarily affected by the presence or absence of structure, whereas N.
