Refining the Use of Habitat Equivalency Analysis

Environmental Management, 2007
When natural resources are injured or destroyed in violation of certain U.S. federal or state statutes, government agencies have the responsibility to ensure the public is compensated through ecological restoration for the loss of the natural resources and services they provide.

Strategies of Habitat Use by Mountain Gorillas

Folia Primatologica, 1991
Patterns of home range use by a mountain gorilla group are examined here in relation to variation in food abundance and quality, diet quality and rainfall, to interactions between different social units and to the distribution of hazards (poaching risk).

Habitat-Net: Habitat interpretation using deep neural nets

2018
Biological diversity is decreasing at a rate of 100-1000 times pre-human rates [1] [2], and tropical rainforests are among the most vulnerable ecosystems. To avoid species extinction, we need to understand factors influencing the occurrence of species.

Assessing Habitat Use and Movement

2004
Sharks occur in all of the world oceans and in waters that include deep-sea, oceanic, neritic, and estuarine habitats. In addition, a few specialized species also occur in rivers and lakes connected to the ocean. The occurrence of sharks within these broad regions is well understood for most species.

Selection and Use of Habitat of Wintering Migrants

1990
The objectives of this chapter are to discuss which habitats migrants choose for the winter quarters, and how they use these habitats. This discussion will focus on small migrant land birds that move from high to tropical latitudes. Therefore, the term “migrants” refers to north temperate species that winter at tropical and subtropical latitudes, and ...

Evolutionary dynamics of habitat use

Evolutionary Ecology, 1997
I examine the evolution of alternate genotypes that use two habitats that differ in vegetative cover, focusing on the interplay between ecological dynamics of the community and changes in selective advantage. Facultative habitat choice can stabilize a predator population that would cycle if isolated in the more open habitat.

Waterfowl Habitat Is Beneficial Use

Journal AWWA, 1995
A farmer's activities in improving on an interconnected drainage system of a wetland site did not constitute “normal farming,” and the farmer was thus not exempt from the Clean Water Act's requirement that a permit be obtained for the discharge of dredged or fill material into waters of the United States.
