Influence of habitat structure on Pristimantis species (Anura: Craugastoridae) in a bamboo-dominated forest fragment in southwestern Amazonia

open access: yesPhyllomedusa: Journal of Herpetology, 2015
Structural and determinate factors for the composition of assemblages of species are diverse. Two theories attempt to explain the pattern of species composition in assemblies using different approaches—i.e., Niche Theory and Neutral Theory.

How do we share food? Feeding of four amphibian species from an aquatic habitat in south–western Romania [PDF]

open access: yesAnimal Biodiversity and Conservation, 2013
The feeding of four amphibian species (Triturus cristatus, Lissotriton vulgaris, Bombina variegata, Pelophylax ridibundus) was studied in 2011, in south–western Romania.

Can predators stabilize host–parasite interactions? Changes in aquatic predator identity alter amphibian responses and parasite abundance across life stages

open access: yesEcology and Evolution, 2022
The role of parasites can change depending on the food web community. Predators, for instance, can amplify or dilute parasite effects on their hosts.

Engineered Living Systems With Self‐Organizing Neural Networks: From Anatomy to Behavior and Gene Expression

open access: yesAdvanced Science, EarlyView.
Ectodermal tissue excised from Xenopus embryos self‐organizes into a three‐dimensional mucociliary organoid. Here, we generate a neural variant, termed neurobot, by implanting neural precursor cells. Neurobots develop mature neurons, adopt distinct morphologies, exhibit more complex motility, and respond differentially to neuroactive compounds. Imaging

Islet Amyloid Polypeptide Modelled to Simulate Diabetes Co‐Oligomerized with β‐Amyloid 1‐42 Reproducing the Pathological Cascade of Alzheimer's Disease in Human Cerebral Organoids

open access: yesAdvanced Science, EarlyView.
Human islet amyloid polypeptide (hIAPP) was used to mimic T2DM, and Aβ42‐hIAPP co‐oligomers were delivered into the human mature cerebral organoids (COs), which reproduce typical AD pathology and significant neuronal death more closely resembling that of AD patients.

Selectivity Filter Dynamics Define Ion Conductance and Selectivity Differences in CNG and HCN Channels

open access: yesAdvanced Science, EarlyView.
Cyclic nucleotide‐gated (CNG) and hyperpolarization‐activated cyclic nucleotide‐gated (HCN) channels share substantial sequence and structural similarity but differ markedly in ion conductance and K+ selectivity. Microsecond‐scale atomistic MD simulations qualitatively reproduced the conductance differences observed in single‐channel recordings and ...

Conservation translocations for amphibian species threatened by chytrid fungus: A review, conceptual framework, and recommendations

open access: yesConservation Science and Practice, 2021
Emerging infectious diseases are an increasingly prominent threat to biodiversity. However, traditional methods in conservation generally have limited efficacy in the face of disease threats.

Heterogeneous Wettability‐Based Construction of Two‐Phase Interfaces for Underwater Reversible Adhesion

open access: yesAdvanced Science, EarlyView.
The design employs heterogeneous wettability surfaces that construct stable oil‐water interfaces to achieve robust and rapid reversible adhesion. Linear enhancement of adhesion strength is realized through multi‐interface patterning. This adhesive enables rapid on‐demand detachment within five seconds via voltage‐induced electrolysis, offering a level ...

Lethal and Sublethal Effects of Glyphosate (Roundup® Active) to Embryos of Colombian Anurans

open access: yesActa Biológica Colombiana, 2013
Glyphosate is an herbicide widely used in agriculture, which may affect non-target species. The aim of this study was to determine the lethal (Median lethal concentration - LC50) and sublethal effects (changes on body size and development) of glyphosate (
