Juncus emmanuelis [PDF]

open access: yes, 2018
This species is endemic to a small area in the southwestern Iberian Peninsula, with subpopulations scattered in approximately 16 localities. It is assessed as Endangered (EN B2ab(ii,iii,iv)) because it has an Area of Occupancy (AOO) of less than 500 km2 ...

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 ...

Aloe littoralis - a review of this widespread African species [PDF]

open access: yes, 2018
The history and natural distribution of Aloe littoralis are discussed and the species is described both in habitat (principally in Namibia) and in cultivation. Notes on its flowering, conservation status, common names and appearance in a Coat of Arms are

Use of Occupancy Models to Evaluate Expert Knowledge-based Species-Habitat Relationships

open access: yesAvian Conservation and Ecology, 2012
Expert knowledge-based species-habitat relationships are used extensively to guide conservation planning, particularly when data are scarce. Purported relationships describe the initial state of knowledge, but are rarely tested.

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part II Deriving instrument‐specific correction equations for meta‐analyses using published data

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has emerged as a valuable method for investigating the feeding ecology of vertebrates. Over the past decade, three‐dimensional topographic data from microscopic regions of tooth surfaces have been collected, and surface texture parameters have been published for both extant and fossil species.

Ecological benefits of tourism management and the challenges of habitat classification

open access: yesGlobal Ecology and Conservation
Nature-based tourism is increasingly popular, with destination competitiveness tied to natural assets or protection status. While tourism often poses conservation challenges, limited research explores its potential ecological benefits when management ...

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

open access: yesThe 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 ...

Wildlife habitat conservation needs in Florida: updated recommendations for strategic habitat conservation areas

open access: yes, 2009
In 1994, researchers from the Florida Fish and Wildlife Conservation Commission (FWC) completed a report, entitledClosing the Gaps in Florida’s Wildlife Habitat Conservation System, assessing the security of rare and imperiled species on existing conservation lands in Florida.
