Special Issue Information

Dear Colleagues,

In the context of ongoing climate change that becomes effective at global, regional, and local levels, understanding animals’ adjustments to environmental fluctuations is of high importance. In all of this work, amphibians and reptiles, as ectotherms that rely on their ambient environmental temperature to regulate most aspects of their biology, have been important model organisms to address questions related to climate change effects. With this Special Issue, we aspire to present novel findings in the field of ectotherms’ thermoregulation, physiological performance, and ecology in relation to how species respond to environmental changes and how the different environmental conditions affect species biology. We warmly invite contributions from biologists, physiologists, ecologists, and evolutionary biologists aiming at understanding the adaptive and non-adaptive responses of reptiles and amphibians to environmental shifts. Submissions exploring these effects in vivo and in vitro are particularly encouraged.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Animals is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Amphibian conservation concerns frequently center on the idea of ‘saving’ them, with the underlying assumption they are the passive victims of anthropogenic environmental change. But this approach ignores the physiological, biochemical, and behavioral flexibility amphibians have employed since they first evolved ~365 million years ago. One overlooked advantage amphibians possess in the struggle for survival, and one humans might use in their efforts to conserve them, is their brains share the same blueprint as human brains, which allows them to acquire knowledge and understanding through experiences—in other words, amphibians have cognitive capabilities that assist them in their effort to survive. Here, we use four examples from our work on the behavioral ecology of Crawfish Frogs (Rana areolata) to form hypotheses about how cognition affects amphibian reaction to environmental and social change. The first two examples describe Crawfish Frog responses to seasonality and reproductive status, the third details their reaction to ecological disturbance, and the fourth describes how their response to the same stimulus changes with growth/age. In each example, we detail the neuronal circuitry thought to be involved and hypothesize the role of cognition. We propose that as one component of our fight to conserve amphibians, researchers should consider the full range of anatomical, physiological, biochemical, and behavioral features amphibians themselves employ in their defense, which are features responsible for their historical evolutionary success up until the Anthropocene. Further, we submit that acknowledging amphibians possess cognitive abilities can enrich interpretations of not only behavioral and ecological observations but also of neuroanatomical and neurophysiological results.
