Bromeliad selection by two salamander species in a harsh environment.

PLoS ONE, 2014
Bromeliad phytotelmata are frequently used by several Neotropical amphibian taxa, possibly due to their high humidity, microclimatic stability, and role as a refuge from predators.

The rhythm of the night: Assessing temporal variation of activity patterns in arhythmic environments from field data

Ecosphere, Volume 17, Issue 8, August 2026.
Abstract Ecologists and zoologists have worked for centuries to understand the spreading, extent, and regulation of biological rhythms among eukaryotes living in arhythmic ecosystems. Investigating whether the long‐standing hypothesis that biological clocks went lost in species inhabiting arhythmic environments can thus have broad implications in ...

FECUNDITY IN PRIMITIVE PLETHODONTID SALAMANDERS [PDF]

Evolution, 1969
The Plethodontidae, with 23 genera and over 180 species, has more living members than any other family of salamanders. The geographic distribution of the group includes most of the forested region of temperate North America, the American tropics, and a restricted area of southern Europe.

A comparison of monitoring methods for inferring demographics of a pond‐breeding amphibian population over 14 years

The Journal of Wildlife Management, Volume 90, Issue 6, August 2026.
We used 4 sampling methods to estimate or index the abundance and sex ratio of spotted salamanders (Ambystoma maculatum) over 14 years. The present study highlights the importance of considering individual heterogeneity in capture probability when estimating abundance of pond‐breeding amphibians from capture data with imperfect detection. Abstract Long‐

Vertebrate hosts as islands: dynamics of selection, immigration, loss, persistence and potential function of bacteria on salamander skin

Frontiers in Microbiology, 2016
Skin bacterial communities can protect amphibians from a fungal pathogen; however, little is known about how these communities are maintained. We used a neutral model of community ecology to identify bacteria that are maintained on salamanders by ...

Military lands provide an opportunity to recover red wolves

The Journal of Wildlife Management, Volume 90, Issue 6, August 2026.
Red wolf (Canis rufus) recovery remains challenging, with only one population persisting and no reintroductions since 1998. Despite extensive, biodiverse properties in the Southeast with conservation mandates, military lands have been overlooked. In our paper, we evaluate them as a potential path forward for red wolf reintroduction sites.

In search of critically endangered species: the current situation of two tiny salamander species in the Neotropical mountains of Mexico.

PLoS ONE, 2012
Worldwide, one in every three species of amphibian is endangered, 39 species have gone extinct in the last 500 years and another 130 species are suspected to have gone extinct in recent decades.

Macrophage: Biological Functions, Diseases, and Therapeutic Targets

MedComm, Volume 7, Issue 8, August 2026.
Macrophages are sentinel innate immune cells that arise from embryonic precursors and bone marrow monocytes, displaying a functional continuum that transcends the classical M1 (pro‐inflammatory)/M2 (anti‐inflammatory) dichotomy. Under homeostatic conditions, balanced M1/M2 polarization preserves tissue integrity by coordinating immune surveillance ...

Vaccination with Recombinant Baculovirus Expressing Ranavirus Major Capsid Protein Induces Protective Immunity in Chinese Giant Salamander, Andrias davidianus

Viruses, 2017
The Chinese giant salamander iridovirus (CGSIV), belonging to the genus Ranavirus in the family Iridoviridae, is the causative agent of an emerging infectious disease causing high mortality of more than 90% and economic losses in Chinese giant ...

Within‐Island Diversification Generates Lineage‐Specific Climate Vulnerability: Insights From the Taiwan‐Endemic Formosan Duke

Evolutionary Applications, Volume 19, Issue 8, August 2026.
ABSTRACT Global climate change disproportionately threatens island endemics because their restricted ranges and limited dispersal opportunities constrain their ability to shift their distributions. Therefore, when developing conservation strategies for species, it is crucial to incorporate population genomics data with ecological information to ...
