Research overview: predicting carnivore density from prey biomass
OverviewA survey of the strong, general relationship between the abundance of prey and the density of the carnivores that depend on them, a cornerstone of predator ecology. Across species and systems, predato…
Research overview: preventive medicine programs for captive felids
OverviewModern zoos run structured preventive medicine programs for captive felids encompassing routine health monitoring, parasite control, vaccination, nutritional management, dental care, and increasingly…
Research overview: prey biomass and the bottom-up control of big-cat numbers
OverviewThe abundance of big cats is governed largely from the bottom up by the biomass of their prey. This overview synthesizes the strong, repeatedly demonstrated relationship between ungulate prey density…
Research overview: prey density thresholds for felid persistence
OverviewA survey of the minimum prey abundance large cats need to maintain viable populations and why prey depletion is a leading cause of felid decline. Because predator density scales with prey biomass, the…
Research overview: prey depletion and the empty forest syndrome
OverviewMany structurally intact Asian forests now hold few or no tigers because their prey has been hunted out, a phenomenon known as the empty forest syndrome. This overview synthesizes evidence that unsust…
Research overview: prey depletion and the empty forest syndrome
OverviewMany forests across tiger range remain structurally intact yet hold few or no tigers because their large prey have been hunted out, a condition often called the empty forest syndrome. This overview su…
Research overview: prey depletion and the empty forest syndrome for tigers
OverviewAn overview of how the loss of large ungulate prey to human hunting hollows out tiger habitat even where forest cover remains, producing empty forests that cannot support tigers. Because tigers requir…
Research overview: prey depletion as a driver of tiger livestock depredation and attacks
OverviewThis overview synthesises evidence that depletion of wild ungulate prey, through poaching, the bushmeat trade, and habitat loss, drives tigers toward livestock and, in extreme cases, people. It review…
Research overview: prey dynamics for Sundarbans tigers under climate stress
OverviewSundarbans tigers rely on prey such as spotted deer (chital) and wild boar, whose abundance depends on mangrove forest condition and freshwater availability. This overview surveys how climate-driven c…
Research overview: prey vigilance and anti-predator behavior toward cats
OverviewAn overview of the behavioral defenses ungulates and other prey deploy against felid predators, from vigilance scanning to alarm signaling and habitat avoidance. Because cats are stealthy ambush hunte…
Research overview: prey-selectivity indices in felid diet studies
OverviewA methodological survey of the indices used to measure whether felids prefer or avoid prey relative to availability, including the Jacobs index, Ivlev's electivity and related measures central to the…
Research overview: progestin contraceptive suppression in felids
OverviewProgestin-based contraceptives have been used to suppress reproduction in captive cats, but concerns about side effects have shaped their use. This overview surveys the application of progestin contra…
Research overview: protected contact versus free contact management of big cats
OverviewHow keepers interact with dangerous captive carnivores spans a spectrum from free contact, sharing space with the animal, to protected contact, where a barrier always separates human and cat. This ove…
Research overview: protected-area effectiveness for cats under land-use pressure
OverviewProtected areas are the cornerstone of felid conservation, but their effectiveness at stopping habitat loss varies and is tested by mounting land-use and climate pressure. This overview surveys method…
Research overview: protected-area networks and felid movement
OverviewIndividual reserves are rarely large enough to sustain wide-ranging cats on their own, so conservation increasingly relies on networks of protected areas linked by corridors, and this overview examine…
Research overview: prusten as a friendly close-range tiger signal
OverviewTigers and several other large cats produce prusten, also called chuffing, a soft fluttering sound made by blowing air through the nostrils with the mouth closed. This overview surveys observations th…
Research overview: qualitative behaviour assessment and affective state in felids
OverviewQualitative Behaviour Assessment asks trained observers to score the expressive demeanour of an animal, capturing emotional qualities such as relaxed, tense, content or frustrated that quantitative et…
Research overview: quality-of-life assessment and end-of-life decisions for captive felids
OverviewDeciding when a chronically ill or aged big cat's welfare no longer justifies continued life is among the most difficult tasks in captive felid care. This overview surveys structured quality-of-life a…
Research overview: range-wide climate vulnerability assessment for tigers
OverviewBeyond the Sundarbans, tigers across Asia face varied climate exposure layered onto severe habitat loss, prompting range-wide vulnerability thinking. This overview surveys how climate projections, sea…
Research overview: rapid-response teams and conflict tigers
OverviewThis overview synthesises the role of specialised rapid-response teams in managing human-tiger conflict, from Village Tiger Response Teams in the Sundarbans to forest-department units across India and…
Research overview: receptor adaptation and the host jumps of canine distemper virus into felids
OverviewA central question in distemper ecology is how a virus historically associated with dogs repeatedly jumps into cats. This overview surveys research on the molecular basis of canine distemper virus hos…
Research overview: rehabilitation and release of orphan Amur tigers
OverviewIn the Russian Far East, orphaned and conflict-involved Amur tiger cubs have been rehabilitated and released back into the wild, including into areas where tigers had become scarce, offering a distinc…
Research overview: religious and cultural values underpinning tolerance for big cats
OverviewThis overview examines how religious beliefs, sacred associations, and cultural traditions foster, or sometimes undermine, tolerance for big cats. It synthesises cases such as reverence for tigers and…
Research overview: remote drug delivery and darting in felid capture
OverviewRemote drug delivery using dart guns and pole syringes enables chemical immobilization of dangerous or free-ranging felids from a safe distance, a foundational technique for field and zoo capture. Suc…
Research overview: remote sensing for felid habitat change monitoring
OverviewSatellite remote sensing is the backbone of measuring habitat change across the vast ranges of wild cats. This overview surveys the data and methods, optical imagery for land-cover classification, rad…
Research overview: renal disease in captive big cats
OverviewChronic kidney disease is a common cause of illness and death in aging captive big cats, paralleling its prominence in domestic cats and reflecting the longer lifespans achieved in managed care. Capti…
Research overview: retirement of circus and entertainment felids
OverviewAs public attitudes and laws have turned against using big cats in circuses, film and other entertainment, retiring these animals to lifetime care has become a significant welfare undertaking. This ov…
