Exploring the Effects of Anthropogenic Habitat Change on Euplerid Carnivore Occupancy in a Humid Evergreen Forest, South-East Madagascar [PDF]

Mammalian carnivores are vulnerable to anthropogenic pressures, including habitat modifications, disturbance, and the introduction of non‐native species. Forests throughout Madagascar are under persistent pressure from extraction of timber and non‐timber

Little-spotted-cat (Leopardus tigrinus) in the Caatinga: occupancy and activity pattern of an endangered and little known feline in the tropical dry forest from the northeast of Brazil

, 2015
While the carnivores are considered regulators and structuring of natural communities are also extremely threatened by human activities. Endangered little-spotted-cat (Leopardus tigrinus) is one of the lesser known species from the Neotropical cats.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes

Advanced Materials, EarlyView.
Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.

Localized Temperature Monitoring in Mouse Brain during Light Delivery via a Non‐Planar Tapered Fiber‐Integrated µRTD Sensor

Advanced Materials, EarlyView.
We report a multifunctional tapered optical fiber integrating a conformal micro‐resistance temperature detector (µRTD) for local, real‐time thermometry during optical stimulation. The platform combines light‐delivery and temperature sensing within a minimally invasive footprint, enabling detection of sub‐degree cortical heating under representative ...

Conservation threats from roadkill in the global road network

, 2021
Aim The road network is increasing globally but the consequences of roadkill on the viability of wildlife populations are largely unknown. We provide a framework that allows us to estimate how risk of extinction of local populations increases due to ...

Viral Infection‐Inspired Autonomous Detection of Fusion‐Competent Viruses for Screening and Environmental Surveillance

Advanced Materials, EarlyView.
Inspired by viral entry mechanisms, the FUSION assay enables autonomous detection of respiratory viruses via membrane fusion–triggered CRISPR‐Cas13a activation. VEACON selectively fuses with fusion‐competent viruses, triggering fluorescence within confined vesicles.

Molecular Detection of Cytauxzoon spp. in Asymptomatic Brazilian Wild Captive Felids

, 2015
Cytauxzoon. spp. DNA was detected for the first time in blood samples from asymptomatic Brazilian wild captive felids. In 2606, 72 EDTA blood samples from seven wild felids species: Puma concolor (pinna), Leopardus pardalis (ocelot), Puma yagouaroundi ...
