Habitat use and constructions

2022
This chapter describes beaver habitat selection and modification activities. It discusses their unusual ability to modify environments to suit their needs, including lodge and dam construction, location selection for these structures, and alteration of vegetation. Historically beavers have been described as a forest species.

Competitors and Habitat Use

Oikos, 1981
We examine the effects of a species', and its competitor's, density on the choice of habitats exploited by the species in models where there is a cost of selecting only one habitat. The state space of the two species' densities is partitioned into regions where the species take either their preferred habitat (assumed in this paper to be different), or ...

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.

Watershed Land Use and Local Habitat: Implications for Habitat Assessment

Wetlands, 2016
Our understanding of anthropogenic stressor effects on wetland biota and ecosystem processes would benefit from better defined relationships between landscape and local stressors. We assessed the connection between watershed land use and local habitat and local disturbance in Great Lakes coastal ecosystems across a full range of anthropogenic stress ...

Predicting Habitat Quality for Grassland Birds Using Density-Habitat Correlations

The Journal of Wildlife Management, 1986
Predictive models relating densities of 5 grassland bird species to habitat variables were developed and tested using stepwise multiple regression and principal components regression. For most species the models gave poor quantitative estimates. Because there were distinct habitat differences among the study sites used to generate and the study sites ...

Predicting habitat functionality using habitat network models in urban planning

Environment and Planning B: Urban Analytics and City Science
Recently, the European Union adopted a Nature restoration law that aims to stop the ongoing decline of biodiversity and even bring back nature to cities. This is challenging as urbanization is an ongoing process that thrives for more land and densification. In this paper we describe a new Open-Source GIS-tool that automates habitat network analyses and

Valuing biodiversity using habitat types

Australasian Journal of Environmental Management, 2010
The capacity to value biodiversity is important for governments facing the challenge of balancing the financial benefits from the construction of infrastructure, land clearing or agriculture against the benefits associated with the existence of diverse flora and fauna.

Habitat Use and Spatial Structure

1998
Most ecological theory is founded on the dubious notion that environmental conditions are homogeneous. Although it is undeniable that environmental variability increases substantially with the spatial scale of observation (Bell et al. 1993), there is still ample environmental variation within 1m2 plots (Beckett and Webster 1971; Tilman 1982; Lechowicz ...

Riverbird distributions and habitat use

2021
Students determine habitat use by birds associated with rivers, using data collected while moving downriver in boats. They use R to calculate resource selection functions for each species. Results can be compared among species, river reaches, or basins.
