This overview examines the activity and spatial ecology of the Eurasian lynx, drawn from extensive GPS-telemetry research. The species is largely crepuscular and nocturnal, maintaining very large home…

The Eurasian lynx ranges across forests of Europe and Asia, and its spotted coat enables individual identification, making it a frequent subject of camera-trap capture-recapture density studies. This…

The Eurasian lynx is the largest of the lynxes and the most widely distributed, ranging across the forests of Europe, the Caucasus, and Siberia into central and eastern Asia. This overview compiles re…

This overview synthesizes telemetry research on Eurasian lynx in the Alps and Scandinavia, where reintroduced and recovering populations have been studied to understand ranging, dispersal, and predati…

Across much of its range the Eurasian lynx is a specialist predator of small ungulates, and this overview synthesizes studies showing roe deer as the principal prey in Europe, supplemented by chamois,…

An overview of the predator-prey relationship between Eurasian lynx and roe deer, the lynx's principal prey across much of temperate Europe. Lynx are efficient solitary ambush hunters of small ungulat…

The Eurasian lynx, a larger relative of the Canada lynx, occupies forests across Europe and Asia where its future is shaped by both climate and intensive land use. This overview surveys how habitat-su…

The return of the Eurasian lynx to parts of western and central Europe, through both natural recolonization and deliberate reintroduction, is a notable conservation story, and this overview reviews it…

The Eurasian lynx was exterminated from much of central and western Europe and has since been reintroduced to several regions, including the Alps, the Jura, and parts of central Europe. This overview…

The European wildcat occupies forest and agricultural mosaics across Europe, where proximity to settlements brings hybridisation with domestic cats, road mortality and habitat fragmentation. This over…

Fibroblast growth factor 23 (FGF23), a hormone regulating phosphate, rises early in feline CKD as the kidneys struggle to excrete phosphorus, and elevated levels have been associated with disease prog…

Cats can be simultaneously infected with FIV and feline leukemia virus, and coinfection tends to accelerate immune decline and worsen prognosis compared with either virus alone. The two retroviruses d…

Because FIV causes a naturally occurring, lifelong immunodeficiency in an outbred host, it became a prized small-animal model for lentiviral pathogenesis, antiretroviral testing, and vaccine concepts.…

FIV diagnosis traditionally relies on detecting antibodies, since infection is lifelong and antibody usually signals true infection in adult cats. Point-of-care ELISA tests give rapid screening, with…

FIV shares the genomic architecture of primate lentiviruses, encoding gag, pol, and env structural and enzymatic genes alongside accessory genes that regulate replication and immune evasion. Researche…

FIV strains cluster into several genetic subtypes (clades) distributed unevenly across continents, reflecting local transmission histories among free-roaming and owned cat populations. Surveys consist…

FIV is transmitted predominantly through deep bite wounds delivered during territorial fighting, which explains its concentration in intact outdoor male cats. Unlike feline leukemia virus, casual cont…

Developing an FIV vaccine proved difficult because lentiviruses mutate rapidly and protective immunity is hard to elicit. A commercial inactivated dual-subtype whole-virus vaccine was eventually marke…

FIV, like HIV, can invade the central nervous system, and infected cats sometimes develop behavioral changes, altered sleep, cognitive and motor deficits, and electrophysiologic abnormalities. The vir…

Lentiviruses related to domestic-cat FIV circulate widely in wild felid species including lions, pumas, leopards, and others, often at high seroprevalence yet apparently with limited disease in their…

Because FeLV spreads through prolonged close contact such as shared bowls, mutual grooming, and bites, managing it in shelters and multi-cat households requires careful testing, isolation, and housing…

FeLV subgroups enter cells using different host membrane receptors, and identifying these receptors clarified why the subgroups cause different diseases. Subgroup A uses a thiamine transporter, subgro…

Feline leukemia virus exists as distinct subgroups defined by receptor usage and biological behavior. Subgroup A is the transmissible form present in all infections; subgroups B, C, and T arise within…

FeLV diagnosis centers on detecting viral p27 antigen. Point-of-care ELISA tests detect soluble antigen in blood and are highly sensitive for screening, while immunofluorescent antibody (IFA) testing…

FeLV is a major cause of hematopoietic neoplasia in cats, classically producing lymphoma and leukemias through insertional mutagenesis and activation of cellular oncogenes. Historically, FeLV-positive…

Beyond cancer, FeLV frequently causes severe nonregenerative anemia and broader bone marrow suppression, making hematologic disease a leading cause of death in infected cats. The subgroup C variant sp…

FeLV impairs immune function, leaving cats vulnerable to a wide range of secondary bacterial, viral, fungal, and protozoal infections that frequently determine clinical course and survival. The subgro…

The African or Near Eastern wildcat, Felis silvestris lybica, is the direct ancestor of all domestic cats. This overview surveys its ecology, distribution and behaviour, describing a solitary, territo…

A key outcome of recent wildcat taxonomy is the treatment of the European wildcat (Felis silvestris) and the African or Near Eastern wildcat (Felis lybica) as separate species rather than subspecies o…

When Interstate 75 was extended across southern Florida as Alligator Alley, wildlife underpasses with continuous fencing were incorporated specifically to reduce roadkill of the endangered Florida pan…
