Functional stasis and changing habitat preferences among mammalian communities from the PETM of the Bighorn Basin, Wyoming

Cambridge Prisms: Extinction
The transition between the Paleocene and Eocene epochs (ca. 56 Ma) was marked by a period of rapid global warming of 5 °C to 8 °C following a carbon isotope excursion (CIE) lasting 200 ky or less referred to as the Paleocene-Eocene Thermal Maximum (PETM).

Virgin River Spinedace Habitat Preference Study

The UW National Parks Service Research Station Annual Reports, 1987
Thus far in the study, 4 species of endemic fishes and 2 introduced trout species have been collected, measured for total length, and in some cases, weighed, and then released. Sampling has been accomplished by electroshocking on 6, 7, 8, and 9 July, 1987, at 4 sites on the East and North Forks of the Virgin River, as well as 1 site on the Santa Clara ...

Assessing the viability of genebanked seeds from rare, wild plants native to the United States using the D.E.A.D. paradigm

Applications in Plant Sciences, EarlyView.
Abstract Premise Genebanks must maintain viable seeds for decades. Seeds that germinate are clearly alive, but some seeds, often from wild populations, do not germinate because they are dormant, empty, aged, or damaged (D.E.A.D.). This work evaluates the effects of D.E.A.D.

Finite element analysis of feeding in red and gray squirrels (Sciurus vulgaris and Sciurus carolinensis)

The Anatomical Record, EarlyView.
Abstract Invasive gray squirrels (Sciurus carolinensis) have replaced the native red squirrel (Sciurus vulgaris) across much of Great Britain over the last century. Several factors have been proposed to underlie this replacement, but here we investigated the potential for dietary competition in which gray squirrels have better feeding performance than ...

The determinant factors underlying habitat selectivity and preference for Black fish Capoeta capoeta gracilis (Keyserling 1891) in Siyahrud River (a tributary of Sefidrud River basin)

‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2014
Understanding habitat requirements of aquatic organisms is key factor for sustainable exploitation and biodiversity conservation of riverine ecosystems. The habitat preference in fish has extremely important for the management of fish populations.

The effect of natal experience on habitat preferences

Trends in Ecology & Evolution, 2004
Several important problems in ecology, evolution and conservation biology are affected by habitat selection in dispersing animals. Experience in the natal habitat has long been considered a potential source of variation in the habitat preferences displayed when dispersers select a post-dispersal habitat.

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

The Anatomical Record, EarlyView.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

Variation in parrot jaw musculature

The Anatomical Record, EarlyView.
Interspecific morphological differences in some superficial jaw muscles of parrots. Abstract Psittaciformes, the order encompassing parrots and their relatives, are highly diverse and generally known for having a strong beaks used for multiple behaviors. The muscles related to the masticatory apparatus should reflect this functional complexity; however,

Comparative and functional anatomy of masticatory muscles and bite force in opossums (Didelphimorphia, Didelphidae)

The Anatomical Record, EarlyView.
We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...
