Anthropogenic effects of habitat modification on anuran species diversity in a swamp forest area, Kenya

open access: yesAfrican Journal of Ecology, Volume 62, Issue 1, January 2024.
Abstract Anuran species are some of the good environmental indicators of habitat quality and condition in ecosystems. This is due to their amphibious life modes and sensitivity to environmental change caused by rapid expansion of agricultural activities, advancement of forest destruction, climate change and emerging infectious diseases.

Different invasibility of permanent and temporary waterbodies in a semiarid Mediterranean Island [PDF]

open access: yes, 2019
Nonindigenous species (NIS) represent a threat to aquatic biodiversity worldwide. However, freshwater ecosystems in drylands are potentially more prone to biological invasions than those located in temperate regions because of the higher number of ...

Muscle opacity (mo), a new mutant gene in Xenopus laevis, linked to the rusty locus [PDF]

open access: yes, 2017
A new developmental mutant is described in Xenopus laevis (Amphibia, Anura): muscle opacity (mo). Homozygotes die at larval stage 48. The underlying defect, visible at stage 47, is a degeneration of cephalic musculature.

The effect of amidation on the behaviour of antimicrobial peptides [PDF]

open access: yes, 2016
Aurein 2.6-COOH and aurein 3.1-COOH were studied along with their naturally occurring C-terminally amidated analogues. Circular dichroism (CD) and molecular dynamic (MD) simulations were used to study the effects of amidation on the interaction of ...

Characterisation of major histocompatibility complex class I genes in Japanese Ranidae frogs. [PDF]

open access: yes, 2016
The major histocompatibility complex (MHC) is a key component of adaptive immunity in all jawed vertebrates, and understanding the evolutionary mechanisms that have shaped these genes in amphibians, one of the earliest terrestrial tetrapods, is important.
