The niche variation hypothesis predicts hunting returns across human cultures

open access: yesOikos, 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

Fgf-signaling is compartmentalized within the mesenchyme and controls proliferation during salamander limb development

open access: yeseLife, 2019
Although decades of studies have produced a generalized model for tetrapod limb development, urodeles deviate from anurans and amniotes in at least two key respects: their limbs exhibit preaxial skeletal differentiation and do not develop an apical ...

Bleached pigment activates transduction in salamander cones. [PDF]

open access: yes, 1995
We have used suction electrode recording together with rapid steps into 0.5 mM IBMX solution to investigate changes in guanylyl cyclase velocity produced by pigment bleaching in isolated cones of the salamander Ambystoma tigrinum.

How vulnerable are amphibians to climate change? A mechanistic perspective

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Amphibians are frequently identified as highly vulnerable to climate change, yet the mechanisms driving this sensitivity remain uncertain. Approaches that explicitly link physiological mechanisms to environmental variation provide powerful tools for forecasting climate ...

Salamanders aid research into mechanisms of non‐canonical organ regeneration for clinical applications

open access: yesMedicine Advances
Salamanders possess remarkable regenerative capacities for organ regeneration among tetrapod vertebrates. Previous research has primarily focused on studying the regeneration of canonical tissues or organs such as limbs, tail, brain, spinal cord, heart ...

Potential risk of Batrachochytrium salamandrivorans in Mexico.

open access: yesPLoS ONE, 2019
The recent decline in populations of European salamanders caused by the chytrid fungus Batrachochytrium salamandrivorans (Bsal) has generated worldwide concern, as it is a major threat to amphibians.

Allochthonous chemical cues drive predation by a top carnivore

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Identifying the mechanisms by which mobile predators detect and select prey remains a central challenge in sensory biology and functional ecology. This study provides the first direct evidence that chemical cues associated with allochthonous organic matter (e.g.

Hatching asynchrony, survival, and the fitness of alternative adult morphs in \u3ci\u3eAmbystoma talpoideum\u3c/i\u3e [PDF]

open access: yes, 2004
The mole salamander, Ambystoma talpoideum, exhibits both aquatic (gilled) and terrestrial (metamorphosed) adult morphologies. Previous studies have shown the existence of body-size advantages associated with the terrestrial morph in A.

Updated Chorotypes of Terrestrial Vertebrates Shed New Light on Zoogeographical Regions in China

open access: yesIntegrative 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 ...
