Influence of damming on anuran species richness in riparian areas: A test of the serial discontinuity concept

Ecology and Evolution, 2018
Almost all large rivers worldwide are fragmented by dams, and their impacts have been modeled using the serial discontinuity concept (SDC), a series of predictions regarding responses of key biotic and abiotic variables.

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 ...

What drives animal responses to high severity fire? The role of functional traits

Biological Reviews, EarlyView.
ABSTRACT Fire regimes are changing worldwide, with increases in the frequency, extent, and severity of fires posing growing risks to biodiversity. Fire severity – the degree of habitat alteration following fire – strongly influences both immediate survival and long‐term recovery of fauna.

Structure Elucidation and Total Synthesis of Granolides A–C: Ethyl‐branched Sesquiterpenes From the Tropical Frog Gephyromantis granulatus

Chemistry – A European Journal, EarlyView.
Males of the tropical frog Gephyromantis granulatus carry unique ethyl‐branched sesquiterpenoid macrolactones in their scent glands. Their structure elucidation was performed by GC/MS, leading to the proposed structures of the granolides. A flexible enantioselective synthesis confirmed the structures and allowed determination of their absolute ...

Mitonuclear and phenotypic discordance in an Atlantic Forest frog hybrid zone

Ecology and Evolution
Discordance between mitochondrial and nuclear DNA is common among animals and can be the result of a number of evolutionary processes, including incomplete lineage sorting and introgression. Particularly relevant in contact zones, mitonuclear discordance

Nonlinear permuted Granger causality

Canadian Journal of Statistics, EarlyView.
Abstract Granger causality is an established, contentious method that seeks causal temporal connections via association and precedence. While not true causal inference, it assists in mapping networks of information flow that may warrant further study.

Biophysical processes of morphogenesis in lizard lungs

Developmental Dynamics, EarlyView.
Abstract Background The lungs of squamate reptiles (lizards and snakes) are highly diverse, exhibiting single chambers, multiple chambers, transitional forms with two to three chambers, along with a suite of other anatomical features, including finger‐like epithelial projections into the body cavity known as diverticulae.

Mosaic activation of the zebrafish hsp70l heat shock promoter: Implications for interpreting transgenes

Developmental Dynamics, EarlyView.
Abstract Background The promoters and enhancers of heat shock genes, such as the 1.5‐kb promoter of the zebrafish hsp70l gene, are valuable tools for temporal activation of transgenes. It has been widely purported that heat shock treatments result in ubiquitous expression of hsp70l‐driven transgenes.

Role of SoxE transcription factors in development and disease

Developmental Dynamics, EarlyView.
Abstract Sox8, Sox9, and Sox10 arose by multiple rounds of genome duplications from a single SoxE gene in ancestral vertebrates. In this review, we will briefly discuss the molecular structure and function of SoxE transcription factors and their evolutionary origin. We will then discuss their expression, function, and developmental disorders.

Effects of Two Different Dietary Calcium Concentrations on Bone Density and Skin Microbiome in Lemur Tree Frogs (Agalychnis lemur)

Animals
The lemur tree frog (Agalychnis lemur), a critically endangered species, can benefit from ex situ conservation programs; however, managing amphibians under human care presents challenges, including the provision of appropriate nutrition.
