Forest size and avian diversity in New Jersey woodlots with some land use implications.

abstract：:Species-habitat relationships are an important aspect of fish life history, particularly in early ontogeny. To address the lack of information on the microhabitat use/requirements of European coarse fishes, particularly 0-group fishes in riverine systems, an empirical model was generated from data collected in the Riv...
