Systematics of wolves in eastern North America Systematics of wolves in eastern North America
Cranial morphology of Recent wolves throughout northern and western North America is remarkably consistent. Statistical analysis indicates the presence of four subspecies of gray wolf (Canis lupus) there, which are always distinguishable from the sympatric coyote (C. latrans). A fifth gray wolf subspecies, lycaon, occurs in southeastern Canada, and the red wolf (C. rufus), is found in...

The importance of floodplain forests in the conservation and management of neotropical migratory birds in the Midwest The importance of floodplain forests in the conservation and management of neotropical migratory birds in the Midwest
Bottomland forests of the Central Forest Region of the Upper Midwest are found primarily on the floodplains of large rivers and include at least six types of forest communities. Birds breeding in bottomland forests are affected by extensive variation in latitude, climate, hydrology, forest succession, and change caused by anthropogenic disturbances. The floodplain forest bird community...

The management of hunting of Anatidae The management of hunting of Anatidae
The objectives of harvest management for members of family Anatidae typically involve the size of the harvested population and the size of the harvest. Hunting regulations are the primary tool used to try to achieve the objectives of harvest management. Informed harvest management thus requires a knowledge of the relationship between hunting regulations and both Anatid abundance and...

The relevance of the Mediterranean Region to colonial waterbird conservation The relevance of the Mediterranean Region to colonial waterbird conservation
The Mediterranean Sea is the largest partially enclosed sea in the world and provides habitat to more than 100 species of waterbirds from the Palearctic-North African-Middle Eastern regions. Even though the Mediterranean suffers from pollution, has little tidal influence, and is oligotrophic, more than half of the western Palearctic populations of numerous waterfowl species winter in the...

The role of thermal stratification in tidal exchange at the mouth of San Diego Bay The role of thermal stratification in tidal exchange at the mouth of San Diego Bay
We have examined, from an observational viewpoint, the role of thermal stratification in the tidal exchange process at the mouth of San Diego Bay. In this region, we found that both horizontal and vertical exchange processes appear to be active. The vertical exchange in this case was apparently due to the temperature difference between the'bay water and ocean water. We found that the...
