Exploring gaps, biases, and research priorities in the evidence for reptile conservation actions
Conservation Biology, EarlyView.Abstract With over 21% of reptile species threatened with extinction, there is an urgent need to ensure conservation actions to protect and restore populations are informed by relevant, reliable evidence. We examined the geographic and taxonomic distribution of 707 studies that tested the effects of actions to conserve reptiles synthesized in ...

Future Needs in Mast Cell Biology. [PDF]
, 2019 The pathophysiological roles of mast cells are still not fully understood, over 140 years since their description by Paul Ehrlich in 1878. Initial studies have attempted to identify distinct "subpopulations" of mast cells based on a relatively small ...

Effect of Vipera ammodytes ammodytes Snake Venom on the Human Cytokine Network
Toxins, 2018 Local inflammation is a well-known symptom of envenomation by snakes of the family Viperidae, attributed primarily to the phospholipase A2s, metalloproteinases and L-amino acid oxidases contained in their venom.

Emulating duration and curvature of coral snake anti-predator thrashing behaviors using a soft-robotic platform [PDF]
arXiv, 2020 This paper presents a soft-robotic platform for exploring the ecological relevance of non-locomotory movements via animal-robot interactions. Coral snakes (genus Micrurus) and their mimics use vigorous, non-locomotory, and arrhythmic thrashing to deter predation.

Venom Evolution: Gene Loss Shapes Phenotypic Adaptation [PDF]
, 2016 Snake venoms are variable protein mixtures with a multitude of bioactivities. New work shows, surprisingly, that it is the loss of toxin-encoding genes that strongly influences venom function in rattlesnakes, highlighting how gene loss can underpin ...

Variational approximations to homoclinic snaking [PDF]
, 2010 We investigate the snaking of localised patterns, seen in numerous physical applications, using a variational approximation. This method naturally introduces the exponentially small terms responsible for the snaking structure, that are not accessible via standard multiple-scales asymptotic techniques.

Orbis Litterarum, EarlyView.Abstract Fluidity invigorates a utopian home in Chinese Canadian author Larissa Lai's Salt Fish Girl (2002). In the novel, the fishlike lesbian couple cyclically returns to their aquatic habitat between mortal reincarnations: from last‐century colonial South China to near‐future bio‐capitalistic Canada, where they recurrently experience displacement ...

The urgent need to develop novel strategies for the diagnosis and treatment of snakebites [PDF]
, 2019 Snakebite envenoming (SBE) is a priority neglected tropical disease, which kills over one hundred thousand people per year. However, many millions of survivors also suffer through disabilities and long-term health consequences.

Optimizing snake locomotion in the plane. II. Large transverse friction [PDF]
arXiv, 2013 We determine analytically the form of optimal snake locomotion when the coefficient of transverse friction is large, the typical regime for biological and robotic snakes. We find that the optimal snake motion is a retrograde traveling wave, with a wave amplitude that decays as the -1/4 power of the coefficient of transverse friction. This result agrees

Philosophical Perspectives, EarlyView.ABSTRACT In a pure event semantics for natural language, the domain of quantification and predication is limited to events and states. I offer pure event semantic analyses of several phenomena, some of which have not been treated before in formal semantics. In the pure event semantics sketched in the second section, nouns are state predicates, and this
