Conservation of Declining Populations

Conservation of Declining Populations

Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.

Conservation of Small Populations

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

What is Conservation Biology?

What is Conservation Biology?

Conservation biology is a scientific field that focuses on the preservation of biodiversity in order to protect ecosystems while meeting the needs of the human population. Humans require properly functioning ecosystems to maintain our supply of natural resources, including food, medicines, and building materials.

Threats to Biodiversity

Threats to Biodiversity

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Optimal Foraging

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.

Habitat Fragmentation

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.

Summary

This summary is machine-generated.

Tiger conservation in Asia depends on prey availability and habitat quality, not just protected areas. Managing human use in forests is key for tiger persistence in working landscapes.

Ecology

Wildlife Management

Background:

Tiger (Panthera tigris) conservation in Asia relies on protected areas within human-dominated landscapes.
Effective tiger conservation requires metapopulations and habitat use beyond protected area boundaries, including multiple-use forests.
Understanding factors influencing tiger occurrence in working landscapes is crucial but incomplete.

Purpose of the Study:

To assess the influence of protection status, prey, grasslands, human use, and connectivity on tiger occurrence.
To evaluate tiger occupancy and habitat use at multiple spatial scales in the Central Terai Landscape, India.
To inform conservation strategies for tigers in human-dominated landscapes.

Main Methods:

Occupancy modeling was used to analyze tiger sign detection data collected by two observer teams.
Surveys covered 1009 km of trails and water courses across 60 cells within a 5400 km² landscape.
Multiscale analysis examined cell-scale occupancy and segment-scale habitat use based on environmental and management covariates.

Main Results:

Tiger occupancy was primarily influenced by prey availability and habitat quality, not protected area status.
Tiger use of habitat segments was high where prey and grasslands were abundant but decreased with increased human and livestock presence.
Low tiger occupancy was observed in some Indian protected areas connected to larger habitats in Nepal, questioning current strategies.

Conclusions:

Prey availability and habitat quality are more critical than protected area designation for tiger occurrence in working landscapes.
Riparian grasslands may serve as vital refugia for tigers, enabling daytime survival amidst human activity.
Managing human use in high-quality multiple-use forests can complement protected areas for tiger population persistence.
