Leaf heat tolerance in a native Californian shrub responds in expected and unexpected ways to differences in range, season, and sunlight exposure

PLANTS, PEOPLE, PLANET, EarlyView.
Earth's ecosystems are experiencing wide‐ranging impacts from global climate change, including increased average and extreme temperatures. These temperature shifts can drastically affect plant physiology, threatening the future of even common plant species. Here, we focus on photosynthetic function in a native Southern California shrub species.

Captivity may broadly impede bison ecological function: space, season, and management

Frontiers in Conservation Science
American bison (Bos bison) were spared from numerical extinction but considered to be ecologically extinct, partially due to spatial restrictions in their former range.

Using MALDI‐FTICR Mass Spectrometry to Enhance ZooMS Identifications of Pleistocene Bone Fragments Showing Variable Collagen Preservation

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Recent advances in high‐throughput molecular analyses of collagen peptides, especially ZooMS (Zooarchaeology by Mass Spectrometry), have permitted breakthroughs in the analysis of archaeological material that is highly fragmented, a factor that hinders morphological identification.

Restoring Lateral Connectivity to Anthropogenic Riverscapes: Six Lessons From Stage Zero

River Research and Applications, EarlyView.
ABSTRACT Centuries of river modification, particularly straightening and incision, have severely reduced lateral connectivity between rivers and their floodplains. As a result, Stage 0 riverscapes, characterised by high lateral connectivity (e.g., anastomosing or wetland riverscapes), are now rare in anthropogenic landscapes.

Ontologies for Sustainability: Theoretical Challenges

Sustainable Development, EarlyView.
ABSTRACT The lack of sustainable practices in key sectors of human societies is a global concern, posing threats for the whole planet. This paper provides the first review of ontologies for sustainability efforts, outlining their roles in assessing and advancing such efforts. Section 2 outlines three major challenges associated with sustainability: (1)

Diet and morphological variation in bison (Bison bison) from the Bighorn Basin, Wyoming, USA

Frontiers in Ecology and Evolution
Cranial morphology has been used to examine ecological pressures on bison (Bison bison) populations and to place isolated crania within chronological and evolutionary contexts.

A Test of the Coase Conjecture Using Prices of Electronic Books

Southern Economic Journal, EarlyView.
ABSTRACT The Coase Conjecture predicts that a durable‐goods monopolist without commitment will rapidly cut price toward marginal cost. We test this prediction in the electronic‐book market using release‐day prices. To proxy for marginal cost, we use competitive prices of public‐domain electronic books on the same platforms.

Vitamin and mineral status within various tissues of bison: a scoping review

Frontiers in Conservation Science
The North American bison (Bison bison) is gaining prominence in agricultural production systems across North America; however, comprehensive species-specific management guidelines, particularly regarding nutrition, remain limited.

Assessing physiological, behavioral and movement responses to Suprelorin implant delivery methods in free‐ranging eastern grey kangaroos Macropus giganteus

Wildlife Biology, EarlyView.
Overabundant populations of eastern grey kangaroos Macropus giganteus in peri‐urban areas pose ecological and social challenges. Current management strategies are often hindered by animal welfare and logistical concerns. This study aimed to assess stress responses of kangaroos to two contraceptive delivery methods.

MALIGNANT CATARRHAL FEVER IN AMERICAN BISON (Bison bison) IN SLOVENIA

Slovenian Veterinary Research, 2015
Summary: Malignant catarrhal fever (MCF) is a ubiquitous disease of cattle and other ruminants caused by ovine herpesvirus-2 (OvHV-2) in Europe and other continents and alcelaphine herpesvirus-1(AlHV-1) in Africa. In March 2010 MCF was recognized in small private zoological garden in three American bison (Bison bison) imported from Vienna.
