Kategoria BISAC: Nature >> Ecosystems & Habitats - Lakes, Ponds & Swamps

A water strider darts across a pond, its feet dimpling the surface tension; a giant water bug dives below, carrying his mate's eggs on his back; hidden among plant roots on the silty bottom, a dragonfly larva stalks unwary minnows. Barely skimming the surface, in the air above the pond, swarm mayflies with diaphanous wings. Take this walk around the pond with Gilbert Waldbauer and discover the most amazingly diverse inhabitants of the freshwater world.

In his hallmark companionable style, Waldbauer introduces us to the aquatic insects that have colonized ponds, lakes, streams, and...

Enclosed ecosystem experiments have gained in popularity as research tools in ecological science, particularly in the study of coastal aquatic environments. These systems provide scientists with a degree of experimental control that is not achievable through field experiments. Yet to date, techniques for systematically extrapolating results from small-scale experimental ecosystems to larger, deeper, more open, more biologically diverse, and more heterogeneous ecosystems in nature have not been well developed. Likewise, researchers have lacked methods for comparing and extrapolating...

Ninety Fathoms Down is the first collection of Canadian stories about the Great Lakes, the inland seas that shaped the development of Ontario. This fascinating book explains the history of the Canadian side of the Great Lakes by telling the stories of people whose lives took dramatic turns on the vast lakes. In these pages you will meet people like Paul Ragueneau, the Jesuit priest who tried to save thousands of starving Hurons in 1650; the seventeenth-century dreamer Rene-Robert Cavalier de La Salle, whose luck always let him down; and Lt. Miller Worsley, who takes revenge on the...

Proper designation of Essential Fish Habitat (EFH) is a highly important spatial measure in any management of fishery resources. EFH is defined as those waters and substrates necessary to fish for spawning, breeding, feeding, or growth to maturity, a definition that includes the physical, chemical and biological properties of marine areas and the associated sediment and biological assemblages that sustain fish populations throughout their full life cycle.

This book presents latest advances in EFH mapping and modelling and introduces the environmental approach to EFH identification...

Biological invasions by alien (non-native) species are widely recognized as a significant component of human-caused global environmental change and the second most important cause of biodiversity decline. Alien species threaten many European ecosystems and have serious environmental, economic and health impacts. The DAISIE (Delivering Alien Invasive Species Inventories for Europe) project has now brought together all available information on alien species in Europe (terrestrial, aquatic and marine) and from all taxa (fungi, plants, animals). Thus for the first time, an overview and...
