The WUSCHEL gene is required for shoot and floral meristem integrity in Arabidopsis.
Self perpetuation of the shoot meristem is essential for the repetitive initiation of shoot structures during plant development. In Arabidopsis shoot meristem maintenance is disrupted by recessiveExpand

MMP-9/Gelatinase B Is a Key Regulator of Growth Plate Angiogenesis and Apoptosis of Hypertrophic Chondrocytes
Homozygous mice with a null mutation in the MMP-9/gelatinase B gene exhibit an abnormal pattern of skeletal growth plate vascularization and ossification. Although hypertrophic chondrocytes developExpand

The Last Mile: How to Sustain Long-Distance Migration in Mammals
Among Earth's most stunning, yet imperiled, biological phenomena is long-distance migration (LDM). Although the understanding of how and why animals migrate may be of general interest, few site-Expand

PATTERNS OF APPARENT EXTIRPATION AMONG ISOLATED POPULATIONS OF PIKAS (OCHOTONA PRINCEPS) IN THE GREAT BASIN
Abstract We conducted exploratory analyses to examine the relative roles played by natural and anthropogenic influences on persistence of a montane mammal. We revisited historical locations of pikasExpand

Epithelial immaturity and multiorgan failure in mice lacking epidermal growth factor receptor
SINCE the discovery that epidermal growth factor (EGF) can accelerate opening of the eyelids1, the EGF receptor (EGF-R) has been extensively studied and is now considered to be a prototype tyrosineExpand

Recolonizing Carnivores and Naïve Prey: Conservation Lessons from Pleistocene Extinctions
The current extinction of many of Earth's large terrestrial carnivores has left some extant prey species lacking knowledge about contemporary predators, a situation roughly parallel to that 10,000 toExpand

Rapid ecological and behavioural changes in carnivores: the responses of black bears (Ursus americanus) to altered food
Many areas have experienced disproportionate increases in the number of conflicts between large carnivores and humans, and this is especially true in western North America where urban sprawl hasExpand

USING BLACK BEARS TO TEST IDEAL-FREE DISTRIBUTION MODELS EXPERIMENTALLY
Abstract Models on the distribution of animals are invaluable in understanding how individuals and, ultimately, populations respond to ecological processes. Rarely, have they been applied toExpand

Global decline in aggregated migrations of large terrestrial mammals
Knowledge of mammal migrations is low, and human impacts on migrations high. This jeopardizes efforts to conserve terrestrial migrations. To aid the conservation of these migrations, we synthesizedExpand
