Spatial multi-criteria decision analysis to predict suitability for African swine fever endemicity in Africa [PDF]

open access: yes, 2014
Background African swine fever (ASF) is endemic in several countries of Africa and may pose a risk to all pig producing areas on the continent. Official ASF reporting is often rare and there remains limited awareness of the continent-wide distribution ...

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

open access: yesThe 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 ...

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

open access: yesThe 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 ...

Analysis of two decades of Landsat satellite images reveals long-term changes in aquatic and terrestrial vegetation in Bimini, The Bahamas with coastal development

open access: yesFACETS
Tropical coastal ecosystems are often characterized by vegetated marine habitats, including mangroves and seagrass beds. Over past decades, these habitats have been impacted by coastal development resulting in vegetation losses with consequences for ...

Lagomorph cranial biomechanics and the functional significance of the unique fenestrated rostrum of leporids

open access: yesThe Anatomical Record, EarlyView.
Abstract The crania of leporid lagomorphs are uniquely fenestrated, including the posterior cranial bones and the lateral portion of the maxilla. The functional significance of the highly fenestrated rostrum has received considerably little attention, despite being absent in other mammalian herbivores with a long rostrum.

Ecological study of chalk and limestone streams. Annual Report October 1974 to September 1975 [PDF]

open access: yes, 1975
Few detailed studies have been made on the ecology of the chalk streams. A complex community of plants and animals is present and much more information is required to achieve an understanding of the requirements and interactions of all the species. It is
