Comparative feeding ecology of four syntopic Hypostomus species in a Brazilian southeastern river

Brazilian Journal of Biology
Though their broad distribution in most Brazilian rivers, scarce studies concerning ecological interactions on Hypostomus species are available. This study observes the diet, the trophic interactions and some morphological aspects of four syntopic ...

Diet and trophic niche of Lithobates catesbeianus (Amphibia: Anura)

Zoologia (Curitiba), 2012
Lithobates catesbeianus (Shaw, 1802) is an invasive anuran introduced in Brazil that is associated with the displacement and the decline of populations of native species worldwide.

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks

Advanced Science, EarlyView.
Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,

Predicting niche overlap with model‐based ordination

Ecography
The ecological niche is a fundamental concept in ecology that can be used in order better understand species relationships. The overlap in species niches provides a measure of the likelihood for species to co‐occur. Most approaches that quantify niche overlap have been based on distance and similarity indices, for pairwise combinations of species.

Predator-prey temporal niche partitioning under human disturbance: a meta-analysis

Nature Communications
Human disturbances are modifying animal behavior in ecosystems worldwide, with the potential to reshape species interactions. For instance, human-induced shifts in diel activity may disrupt the alignment of daily activity patterns between interacting ...

Phase‐Resolved Dual Control of Phenol Photodissociation at the Air–Water Interface From Structure‐Resolved Statistics

Advanced Science, EarlyView.
Faster phenol photolysis at the air–water interface arises from two cooperative factors: a more favorable initial microenvironment for solvent‐side electron stabilization, which lowers CI access, and a more labile hydrogen‐bond network, which more readily reorganizes to stabilize the dark‐state intermediate.

A Generative Neuro‐Symbolic AI for Protein Sequence Design

Advanced Science, EarlyView.
We introduce EffieDes, a neuro‐symbolic framework coupling deep learning‐based fitness landscape parameterization with exact automated reasoning. Unlike greedy sampling, EffieDes identifies sequences that globally optimize fitness while satisfying intricate design constraints.

Leveraging multiple data sources to assess competition between introduced wild pigs and native deer

Ecosphere
Introduced species have diverse impacts on native wildlife and ecosystems. Negative effects of introduced species on native species through competition or amensalism are frequently hypothesized, but are challenging to test in the field, particularly for ...

EDNRA Forms a Positive Feedback Loop with the Hippo/YAP Axis to Drive Triple‐Negative Breast Cancer Progression

Advanced Science, EarlyView.
Endothelin receptor type A (EDNRA) and the Hippo/YAP pathway form a self‐reinforcing loop that sustains triple‐negative breast cancer. EDNRA activates YAP through Gαq/11–Rho/ROCK–LATS signaling, while YAP/TEAD4 reciprocally drives EDNRA transcription.
