Skin swabs with FTA® cards as a dry storage source for amphibian DNA [PDF]

, 2018
Amphibians are the most endangered group of vertebrates, and conservation measures increasingly rely on information drawn from genetic markers. The present study explores skin swabs with Whatman FTA® cards as a method to retrieve PCR-amplifiable ...

Powerful yet challenging: mechanistic niche models for predicting invasive species potential distribution under climate change

Ecography, Volume 2026, Issue 5, May 2026.
Risk assessments of invasive species present one of the most challenging applications of species distribution models (SDMs) due to the fundamental issues of distributional disequilibrium, niche changes, and truncation. Invasive species often occupy only a fraction of their potential environmental and geographic ranges, as their spatiotemporal dynamics ...

Shifts in the foraging tactics of crocodiles following invasion by toxic prey

Scientific Reports, 2022
Biological invasions can modify the behaviour of vulnerable native species in subtle ways. For example, native predators may learn or evolve to reduce foraging in conditions (habitats, times of day) that expose them to a toxic invasive species.

Non-native Amphibian Pet Trade via Internet in Poland [PDF]

, 2018
Overharvesting and trade in amphibian populations is one of the causes of their global decline. Online trade not only encourages the exploitation of an increasing number of rare and endangered amphibian species from all over the world but also ...

Thermal Plasticity is Regulated by a Key MicroRNA During Range Expansion of an Invasive Fruit Fly

Advanced Science, Volume 13, Issue 23, 23 April 2026.
Populations at the invasion front of Bactrocera dorsalis adapt through reduced phenotypic and gene expression plasticity, a phenomenon likely to be driven by genetic assimilation. We identify a key miRNA‐mediated regulatory axis, in which miR‐276b post‐transcriptionally represses thw, a conserved chitin‐binding gene critical to the cold‐tolerance ...

Correlates of Post‐Introduction Displacement in a Conservation Translocation of Threespine Stickleback

Freshwater Biology, Volume 71, Issue 4, April 2026.
ABSTRACT Predicting the distance between an individual's release point into a new environment and their subsequent location (‘displacement’) could be useful during biological ‘introduction’ events (e.g., invasions/translocations) because variation in displacement could lead to spatially‐structured ecological and evolutionary effects, as well as ...

Vasoactivity of nitrite in the iliac artery of the toadRhinella marina [PDF]

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2018
Nitrite ([Formula: see text]) causes vasodilation in mammals due to the formation of (nitric oxide) NO by endogenous [Formula: see text] reduction in the vascular wall. In this study, we determined if a similar mechanism operates in amphibians. Dual-wire myography of the iliac artery from Rhinella marina showed that applied [Formula: see text] caused a

ONTOGENY OF THE DIET IN ANURANS (AMPHIBIA) COLLECTED AT LA VIEJA RIVER BASIN IN THE DEPARMENTO OF QUINDIO (COLOMBIA)

Caldasia, 2014
The diet of three anuran species, Rhinella marina (Bufonidae), Pristimantis achatinus (Strabomantidae) and Dendropsophus columbianus (Hylidae), that inhabit agroecosystems at the Rio La Vieja Basin (Quindio, Colombia) was examined. The goal of this study

Laid-back invaders: Cane toads (Rhinella marina) down-regulate their stress responses as they colonize a harsh climate

Global Ecology and Conservation, 2020
In response to encountering abiotic extremes, many organisms exhibit stress responses as measured by levels of corticosterone and heat-shock protein (e.g., HSP70) in the blood. Such responses can enhance organismal viability.
