Research overview: iridoid chemistry and nepetalactol in silver vine
OverviewThe active ingredients behind the silver vine and catnip response belong to a class of plant compounds called iridoids, with nepetalactol identified as a particularly potent driver of the reaction in…
Research overview: iridoid responses in big cats and wild felids
OverviewThe response to catnip and related iridoids is not unique to domestic cats; various wild felids also react. This overview surveys reports that some big cats, such as lions and others, show interest in…
Research overview: iris atrophy and pupil function in older cats
OverviewWith age, the iris of a cat's eye can thin and degenerate, a condition called iris atrophy that may affect how the pupil responds to light. This overview surveys age-related iris atrophy in cats, in w…
Research overview: iris musculature controlling the feline slit pupil
OverviewThe vertical-slit pupil is produced by a specific arrangement of iris muscles that constrict and dilate the aperture into a line rather than a shrinking circle. This overview surveys the anatomy of th…
Research overview: is the Chinese mountain cat a species or a wildcat subspecies?
OverviewThe Chinese mountain cat, a sandy-colored felid of the eastern Tibetan Plateau, has been classified both as a full species, Felis bieti, and as a subspecies of the wildcat, Felis silvestris bieti. Thi…
Research overview: is the jaguar a single subspecies?
OverviewHistorically the jaguar was divided into many subspecies, but molecular evidence supports treating it as essentially one continuous species. This overview reviews the debate, explaining that phylogeog…
Research overview: island biogeography of the leopard cat lineage
OverviewThe leopard cat lineage offers a natural laboratory for studying how island isolation shapes felid taxonomy. This overview surveys how leopard cats colonized numerous islands across Asia, from Japan t…
Research overview: islet amyloid in feline diabetes
OverviewDeposition of islet amyloid polypeptide (amylin) within pancreatic islets is a characteristic pathologic feature of feline diabetes, paralleling human type 2 diabetes and contributing to progressive b…
Research overview: isolation risk for southern Canada lynx populations
OverviewLynx populations in the contiguous United States, in the Rockies, Cascades, Great Lakes region, and New England, sit at the warm, dry edge of the species' range and are unusually exposed to climate-dr…
Research overview: isotopic and dietary studies of the American lion
OverviewThis overview surveys what stable isotope and dental studies reveal about the diet of Panthera atrox. By analysing carbon and nitrogen values in the bone collagen of American lions alongside contempor…
Research overview: isotopic evidence for cave lion diet
OverviewThis overview surveys stable isotope studies of cave lion diet, which use carbon and nitrogen values in bone collagen to identify the prey of Panthera spelaea across Ice Age Eurasia and Beringia. Seve…
Research overview: isotopic evidence for proboscidean prey in Homotherium
OverviewThis overview surveys how isotopic and contextual evidence has been used to test the long-standing idea that the scimitar-toothed cat Homotherium specialized in hunting young proboscideans. At sites s…
Research overview: isotopic niche partitioning among Ice Age predators
OverviewThis overview examines how stable isotope studies reveal the way coexisting Ice Age predators divided up prey and habitat. By comparing carbon and nitrogen values in the bone collagen of species such…
Research overview: isotopic reconstruction of Smilodon prey choice
OverviewThis overview surveys how stable isotope studies have been used to identify the prey of Smilodon at sites such as Rancho La Brea. By comparing carbon and nitrogen values in sabertooth bone collagen wi…
Research overview: iterative evolution of the sabertooth ecomorph
OverviewThis overview synthesizes the striking pattern by which a sabertooth body plan evolved repeatedly and independently across unrelated lineages of predatory mammals. True cats (machairodonts), nimravids…
Research overview: jaguar and puma coexistence in the Neotropics
OverviewAcross much of Latin America jaguars and pumas occur together, and their coexistence is mediated by differences in prey, habitat, and behavior. This overview synthesizes research showing that jaguars…
Research overview: jaguar and puma coexistence with smallholders in Mesoamerica
OverviewThis overview reviews human-felid conflict involving both jaguars and pumas across smallholder and indigenous landscapes of Central America, where the two cats overlap and complicate attribution of li…
Research overview: jaguar bite force and the killing of armored prey
OverviewThe jaguar has the most powerful bite relative to size among big cats, and this overview synthesizes research linking its robust skull and jaw musculature to a distinctive killing style. Unlike most l…
Research overview: jaguar coexistence and tourism in the Brazilian Pantanal
OverviewThis overview examines coexistence dynamics in the Pantanal, where high jaguar densities, extensive cattle ranching, and a booming jaguar-tourism industry intersect. It synthesises research on depreda…
Research overview: jaguar conflict and corridors in the Calakmul region, Mexico
OverviewThis overview examines human-jaguar conflict around the Calakmul Biosphere Reserve and the broader Selva Maya of southern Mexico, a critical node in the jaguar's northern range and the Mesoamerican co…
Research overview: jaguar conflict on the Brazilian Cerrado agricultural frontier
OverviewThis overview reviews human-jaguar conflict across Brazil's Cerrado savanna, a rapidly converting agricultural frontier where soy, cattle, and croplands fragment jaguar habitat. It synthesises studies…
Research overview: jaguar density networks and range-wide monitoring
OverviewJaguars are monitored across the Americas through camera-trap capture-recapture, and coordinated initiatives increasingly link local surveys into range-wide networks producing comparable density estim…
Research overview: jaguar depredation and management in Belize
OverviewThis overview reviews human-jaguar conflict in Belize, home to important jaguar populations and the Cockscomb Basin reserve, where small-scale ranchers and farmers experience cattle and occasionally o…
Research overview: jaguar ecology in continuous Amazon rainforest
OverviewThe Amazon basin holds the largest remaining expanse of jaguar habitat, and the cat's ecology there differs from open wetlands. This overview synthesizes research on jaguars in continuous rainforest,…
Research overview: jaguar genetic structure and fragmentation across the Americas
OverviewJaguar populations historically formed a largely connected continental network, but deforestation and barriers are increasingly structuring their genetics. This overview surveys what molecular studies…
