Optimal Foraging00:48

Optimal Foraging

How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.
Ecological Niches02:02

Ecological Niches

All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.
Habitat Fragmentation02:31

Habitat Fragmentation

Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.
Types of Selection01:46

Types of Selection

Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...
Frequency-dependent Selection01:21

Frequency-dependent Selection

When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.
Distribution and Dispersion00:54

Distribution and Dispersion

To understand intra-specific interactions in populations, scientists measure the spatial arrangement of species individuals. This geographic arrangement is known as the species distribution or dispersion. Highly territorial species exhibit a uniform distribution pattern, in which individuals are spaced at relatively equal distances from one another. Species that are highly tied to particular resources, such as food or shelter, tend to concentrate around those resources, and thus exhibit a...

Summary

Woodland caribou (Rangifer tarandus caribou) avoid forestry at broad scales and linear features at fine scales. A single scale-integrated resource selection function (SRSF) effectively maps habitat suitability for conservation.

Area of Science:

  • Ecology
  • Wildlife Conservation
  • Spatial Modeling

Background:

  • Species distribution is influenced by habitat suitability across multiple spatial and temporal scales.
  • Translating multi-scale habitat suitability to single spatial maps for conservation is challenging.
  • Anthropogenic disturbances like forestry and linear features can impact species distributions.

Purpose of the Study:

  • To investigate the multi-scale effects of forestry and linear features on woodland caribou (Rangifer tarandus caribou) distribution.
  • To develop and validate scale-integrated resource selection functions (SRSFs) for habitat suitability mapping.
  • To support conservation efforts for threatened species through improved habitat mapping.

Main Methods:

  • Estimation of resource selection functions (RSFs) at three distinct spatial scales for woodland caribou.
  • Analysis of avoidance patterns related to forestry cut-blocks and linear features across scales.
  • Development and validation of a single SRSF synthesizing multi-scale selection data.

Main Results:

  • A scale-specific avoidance pattern was observed: woodland caribou avoided forestry at broad scales and linear features at fine scales.
  • These avoidance patterns align with predictions of predator-mediated effects.
  • A single SRSF demonstrated comparable predictive accuracy to single-scale RSFs across different prediction scales.

Conclusions:

  • Resource selection by woodland caribou exhibits scale-dependent responses to anthropogenic disturbances.
  • A single SRSF can effectively integrate multi-scale selection data for habitat suitability mapping.
  • SRSFs offer a valuable tool for critical habitat identification and species recovery planning.
