Re-isolating Batrachochytrium dendrobatidis from an amphibian host increases pathogenicity in a subsequent exposure. [PDF]

open access: yesPLoS ONE, 2013
Controlled exposure experiments can be very informative, however, they are based on the assumption that pathogens maintained on artificial media under long-term storage retain the infective and pathogenic properties of the reproducing pathogen as it ...

Detection of environmental DNA from amphibians in Northern Europe applied in citizen science

open access: yesEnvironmental DNA, Volume 5, Issue 6, Page 1429-1448, November 2023., 2023
Getting help from high school students for sampling and laboratorial setup allowed for the monitoring of eDNA from amphibians in Denmark. With more than 2000 qPCR setups it was possible to validate species‐specific eDNA assays for detection of nine out of 14 species of amphibians in northern Europe.

Faunistic review of amphibians in protected areas of Ukrainian Roztochia

open access: yesБіологічні студії, 2020
Background. Study of amphibian fauna as a necessary component of ecosystems is always relevant and requires a regular renewal of information, especially in protected areas.

Parallel adaptation to lower altitudes is associated with enhanced plasticity in Heliosperma pusillum (Caryophyllaceae)

open access: yesThe Plant Journal, Volume 115, Issue 6, Page 1619-1632, September 2023., 2023
Significance Statement In early stages of adaptation to hotter and drier habitats, an alpine plant in the carnation family shows increased expression plasticity at ecologically relevant genes. This paper investigates two contrasting hypotheses regarding the role of phenotypic plasticity during evolution of alpine/montane plant ecotypes.

Some like it salty: Spatio‐temporal dynamics of salinity differentially affect anurans and caudates in coastal wetlands

open access: yesFreshwater Biology, Volume 68, Issue 7, Page 1279-1292, July 2023., 2023
Abstract Coastal wetlands are naturally subjected to salinity, which is expected to increase through global climate changes. Most species will be affected by these changes, leading to major consequences for community structure and ecosystem functioning.

Consumptive and nonconsumptive effects of omnivorous tadpoles on aquatic invertebrate communities

open access: yesEcosphere, Volume 14, Issue 4, April 2023., 2023
Abstract Consumptive effects (CEs) of predation have been well‐studied in most aquatic systems, but nonconsumptive effects (NCEs) on prey have only recently received limited attention. As aquatic consumers, tadpoles have traditionally been considered strict herbivores, leaving their predatory impacts via CEs and NCEs largely unexplored.

Environmental DNA (eDNA) detects temporal and habitat effects on community composition and endangered species in ephemeral ecosystems: A case study in vernal pools

open access: yesEnvironmental DNA, Volume 5, Issue 1, Page 85-101, January 2023., 2023
Vernal pools are temporary wetlands that can form during a rainy season, often in Mediterranean climates, and serve as ideal testing grounds to understand species detection using eDNA and how biological communities may shift across time and spatial and environmental heterogeneity.

Interactions between Eastern Newts and Wood Frogs in an anthropogenically altered wetland system in eastern Kentucky [PDF]

open access: yes, 2014
A key characteristic of the ridge-top ecosystem in eastern Kentucky is the presence of ephemeral wetlands. Ephemeral wetlands of the ridge-top ecosystem support an amphibian community assemblage characterized by species with short larval periods (e.g ...

A second record of the Eastern Spadefoot Toad (Amphibia: Anura: Megophryidae: Leptobrachium bompu Sondhi & Ohler, 2011) with a note on its morphological variations and natural history

open access: yesJournal of Threatened Taxa, 2017
A single male specimen of Leptobrachium bompu was collected from Talle Valley Wildlife Sanctuary, Lower Subansiri District, Arunachal Pradesh in 2015.
