Habitat management to conserve natural enemies of arthropod pests in agriculture.

Annual Review of Entomology, 2000
Many agroecosystems are unfavorable environments for natural enemies due to high levels of disturbance. Habitat management, a form of conservation biological control, is an ecologically based approach aimed at favoring natural enemies and enhancing ...

Effects of habitat fragmentation on birds and mammals in landscapes with different proportions of suitable habitat: a review

, 1994
Habitat fragmentation implies a loss of habitat, reduced patch size and an increasing distance between patches, but also an increase of new habitat. Simulations of patterns and geometry of landscapes with decreasing proportion of the suitable habitat ...

Prokaryotes and Their Habitats

1981
Prokaryotes are well recognized as essential members of the biosphere. They inhabit all possible locations for life to exist, from those offering ideal conditions for growth and reproduction to those representing extreme environments at the borderline of abiotic conditions.

Ecological Responses to Habitat Fragmentation Per Se

, 2017
For this article, I reviewed empirical studies finding significant ecological responses to habitat fragmentation per se—in other words, significant responses to fragmentation independent of the effects of habitat amount (hereafter referred to as habitat ...

Compositional Analysis of Habitat Use From Animal Radio-Tracking Data

, 1993
Analysis of habitat use based on radio-tagged animals presents difficulties inadequately addressed by current methods. Areas of concern are sampling level, data pooling across individuals, non-independence of habitat proportions, differential habitat use

Habitats of Life [PDF]

, 2008
There are four principal habitats in which life may exist—the surface of a planetary body, its subsurface, its atmosphere and space. From our own experience we know that life does exist on the surface of a planet, in its subsurface and transiently at least in the atmosphere.

Habitat fragmentation versus fragmented habitats

Biodiversity and Conservation, 2012
Habitats often show similar present structuring, but contrasting histories: habitats occur naturally fragmented due to abiotic or biotic factors over long time periods, but may also have become fragmented only recently through transformation from interconnected to highly fragmented habitats within short time periods. Species and populations being faced

Habitat Management to Suppress Pest Populations: Progress and Prospects.

Annual Review of Entomology, 2017
Habitat management involving manipulation of farmland vegetation can exert direct suppressive effects on pests and promote natural enemies. Advances in theory and practical techniques have allowed habitat management to become an important subdiscipline ...
