Bite of the cats: relationships between functional integration and mechanical performance as revealed by mandible geometry.
- BiologySystematic biology
There is significant correlation between integration at the clade level and per-clade averaged stress values, on both original data and by partialling out interclade allometry from shapes when calculating integration, which suggests a strong interaction between natural selection and the evolution of developmental and functional modules at theClade level.
Hyaenidae (Carnivora, Mammalia) from late Miocene and Pliocene of Çalta (Ankara, Turkey)
The two vertebrate localities of Çalta are located about 50 km northwest of Ankara in Central Anatolia. Çalta-1 has yielded a rich early Pliocene fauna that was the subject of an exhaustive study in…
Genomic insights into body size evolution in Carnivora support Peto’s paradox
- Biology, Environmental ScienceBMC genomics
A comparative genomics analysis of 20 carnivores suggested that large carnivores might have evolved an effective mechanism to resist cancer, which could be regarded as molecular evidence to support Peto’s paradox.
Caracal caracal (Carnivora: Felidae)
- Environmental ScienceMammalian Species
The caracal is a slender, medium-sized cat characterized by a short tail and long ear tufts and is found throughout Africa, north to the Arabian Peninsula, the Middle East, central and southwest Asia into India; its habitat includes arid woodlands, savanna, scrublands, hilly steppes, and arid mountainous regions.
Insectivory by Five Sympatric Carnivores in Cool-Temperate Deciduous Forests
- Environmental Science
Study of insectivory by five carnivores in a cool-temperate deciduous forest in Japan found that insects in feces may provide information on the dietary and habitat preferences of these carnivores.
Resolving the relationships of Paleocene placental mammals
- Geography, Environmental ScienceBiological reviews of the Cambridge Philosophical Society
The largest cladistic analysis of Paleocene placentals to date is presented, from a data matrix including 177 taxa (130 of which are Palaeogene) and 680 morphological characters, and supports an Atlantogenata–Boreoeutheria split at the root of crown Placentalia, the presence of phenacodontids as closest relatives of Perissodactyla, and the validity of Euungulata.
Hierarchy in adaptive radiation: A case study using the Carnivora (Mammalia)
- Environmental Science, BiologyEvolution; international journal of organic evolution
Evaluating the support for an early burst model of adaptive radiation in 14 ecomorphological traits plus body mass for the extant mammalian order Carnivora and its constituent families finds strong support for early bursts of dental evolution, suggesting a classic Simpsonian adaptive radiation along dietary resource axes.
Noninsect-Based Diet Leads to Structural and Functional Changes of Acidic Chitinase in Carnivora
- BiologyMolecular biology and evolution
It is shown that a noninsect-based diet has caused structural and functional changes in Chia during the course of evolution in Carnivora and that dietary changes affect the structure and activity of Chia.
Dietary specialization is linked to reduced species durations in North American fossil canids
- Environmental ScienceRoyal Society Open Science
A nonlinear relationship between species duration and degree of carnivory is found: species at either end of the carnivory spectrum tend to have shorter durations than mesocarnivores, and locality coverage shows no relationship with size, diet or duration.
Guardian dogs for livestock and protection in Australia
Wild predators can form a threat to livestock production all over the world. Lethal methods are often used to control predators, however, lethal control has many disadvantages. Livestock Guardian…

Energetic constraints on the diet of terrestrial carnivores
- Environmental Science, GeographyNature
It is shown, by reviewing the most common live prey in carnivore diets, that there is a striking transition from feeding on small prey to large prey (near predator mass), occurring at predator masses of 21.5–25 kg, and the predicted maximum mass that an invertebrate diet can sustain is predicted.
The Ecological Role of the Mammalian Mesocarnivore
- Environmental Science
Examples where mesocarnivores drive community structure and function in roles similar to, or altogether different from, their larger brethren substantiate the need for an assessment of the ecological role of mammalian carnivores beyond an examination of only the largest species.

Causes and consequences of marine mammal population declines in southwest Alaska: a food-web perspective
- Environmental SciencePhilosophical Transactions of the Royal Society B: Biological Sciences
Populations of sea otters, seals and sea lions have collapsed across much of southwest Alaska over the past several decades. The sea otter decline set off a trophic cascade in which the coastal…

Molecular and Evolutionary History of Melanism in North American Gray Wolves
- Biology, Environmental ScienceScience
It is shown that the melanistic K locus mutation in North American wolves derives from past hybridization with domestic dogs, has risen to high frequency in forested habitats, and exhibits a molecular signature of positive selection.
A Simple Genetic Architecture Underlies Morphological Variation in Dogs
