Timothy B. Grabowski, Vilhjalmur Thorsteinsson, Gudrun Marteinsdottir
2014, Marine Ecology Progress Series (506) 279-290
Electronic data storage tags (DSTs) were implanted into Atlantic cod captured in Icelandic waters from 2002 to 2007 and the depth profiles recovered from these tags (females: n = 31, males: n = 27) were used to identify patterns consistent with published descriptions of cod courtship and spawning behavior. The individual...
Stream water temperature limits occupancy of salamanders in mid-Atlantic protected areas
Evan H. Campbell Grant, Amber N. M. Wiewel, Karen C. Rice
2014, Journal of Herpetology (48) 45-50
Stream ecosystems are particularly sensitive to urbanization, and tolerance of water-quality parameters is likely important to population persistence of stream salamanders. Forecasted climate and landscape changes may lead to significant changes in stream flow, chemical composition, and temperatures in coming decades. Protected areas where landscape alterations are minimized will therefore...
