Loss, persistence and reversal of phenotypic traits
Biological Reviews, EarlyView.ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

Streptozotocin induced hyperglycemia in the axolotl
Developmental Dynamics, EarlyView.Abstract Background Diabetes is a group of diseases characterized by loss of β cell mass and/or function, resulting in hyperglycemia. With no established curative treatment, this has initiated research in β cell regeneration. Current animal models have either limited regenerative capacity (mice) or small size and evolutionary distance from humans ...

Reintroduction and Post-Release Survival of a Living Fossil: The Chinese Giant Salamander.
PLoS ONE, 2016 Captive rearing and reintroduction / translocation are increasingly used as tools to supplement wild populations of threatened species. Reintroducing captive-reared Chinese giant salamanders may help to augment the declining wild populations and conserve

Global Ecology and Conservation, 2019 Conserving amphibian populations living in urban areas is challenging due to a lack of information about urban amphibian natural history, ecology, and responses to habitat management.

Digits lost or gained? Evidence for pedal evolution in the dwarf salamander complex (Eurycea, Plethodontidae). [PDF]
PLoS ONE, 2012 Change in digit number, particularly digit loss, has occurred repeatedly over the evolutionary history of tetrapods. Although digit loss has been documented among distantly related species of salamanders, it is relatively uncommon in this amphibian order.

Ecography, EarlyView.Risk assessments of invasive species present one of the most challenging applications of species distribution models (SDMs) due to the fundamental issues of distributional disequilibrium, niche changes, and truncation. Invasive species often occupy only a fraction of their potential environmental and geographic ranges, as their spatiotemporal dynamics ...

Monitoring mercury across the National Wildlife Refuge System using a biosentinel approach
The Journal of Wildlife Management, EarlyView.We measured mercury concentrations in 1,356 dragonfly larvae collected from 30 National Wildlife Refuges across the United States and found wide variability among refuges, spanning the full range reported for other protected lands. Using a management‐focused mercury impairment index, 80% of refuges contained sites classified as moderate or higher risk.

The niche variation hypothesis predicts hunting returns across human cultures
Oikos, EarlyView.The niche variation hypothesis (NVH) proposes that a broader population niche arises from greater individual specialization. Despite decades of empirical testing, research remains constrained to non‐human foragers, and the generality of NVH may extend beyond wildlife. The analysis of > 8000 hunting records from 12 human societies across four continents

Updated Chorotypes of Terrestrial Vertebrates Shed New Light on Zoogeographical Regions in China
Integrative Zoology, EarlyView.Chorotype represents a fundamental concept for identifying groups of species that share similar distribution patterns. However, the last comprehensive revision of animal chorotypes in China was performed more than a decade ago. Here, we update the chorotype classifications for 1040 species and propose an updated zoogeographical regionalization scheme ...

Ecological implications of metabolic compensation at low temperatures in salamanders [PDF]
PeerJ, 2016 Global warming is influencing the biology of the world’s biota. Temperature increases are occurring at a faster pace than that experienced by organisms in their evolutionary histories, limiting the organisms’ response to new conditions.
