Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

A Nested Demand Shares Model of Artificial Marine Habitat Choice by Sport Anglers [PDF]
There is growing public interest in the development of artificial habitats to enhance and diversify coastal marine resources for recreational and commercial uses. In this article, a hierarchical discrete choice model of recreational demand for artificial

Abstract Muscle architecture is a major determinant of muscle performance and, in mammalian lineages, has been correlated with both feeding ecology and locomotor behaviors. Over the past decade, contrast‐enhanced micro‐CT (DiceCT) has emerged as an alternative to traditional dissection‐based measurement.

Trade‐offs in habitat use and occupancy of bats across the gradient of urbanization and seasons
Urbanization that occurs across a gradient from low‐ to high‐density development, is a primary driver of landscape change that can affect biodiversity. Animals balance trade‐offs in obtaining resources and avoiding anthropogenic disturbances across the ...

Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

Why do ICDPs fail? The relationship between subsistence farming, poaching and eco- tourism in wildlife and habitat conservation [PDF]
In this paper we investigate the reasons why integrated conservation and development projects (ICDPs) fail to achieve their conservation goals. We develop a bio-economic model of open access land and wildlife exploitation, which is consistent with many ...

Abstract As habitat salinity markedly differs between the endangered, freshwater‐dwelling Saimaa ringed seal (Pusa saimensis Nordquist, 1899) and the brackish water‐inhabiting Baltic ringed seal (Pusa hispida botnica Gmelin, 1788), we investigated whether this difference has resulted in morphological changes to their kidneys.

Allocation of Land at the Rural-Urban Fringe Using a Spatially-Realistic Ecosystem Constraint [PDF]
Development in rural-urban fringe communities is increasing with the potential to damage healthy ecosystems and endanger the long-term persistence of resident flora and fauna.

Abstract The green iguana (Iguana iguana) is an iguanine lizard with herbivorous and arboreal habits, whose distribution spans through South America, Central America to the south of North America. Although the genus Iguana is well‐known, the species still lacks a comprehensive and up‐to‐date anatomical study, particularly addressing the axial skeleton,

Studies of habitat use in breeding birds often assume species have relatively stable breeding distributions. Some species, however, display considerable year‐to‐year variability, complicating efforts to determine suitable or preferred habitats.
