Photovoltaic Effect in a III‐IV‐V Compound Semiconductor
A large reduction of the GaAs band gap is obtained with incorporation of 6.5% Ge during epitaxy without introducing extended defects or composition inhomogeneity. Heterojunction solar cell devices were fabricated with 0.76‐V open circuit voltage and an internal quantum efficiency above 40% at energies below the bandgap of the GaAs emitter.

We compared two island populations of Bethencourtia palmensis and their culturable endophytic fungi, revealing distinct plant chemistries and a higher biopesticidal potential in the endophytic fungi from La Palma population along with high potential for the discovery of novel compounds.

Rodent outbreaks have significant socio‐economic impacts worldwide, and anticipation is crucial for timely management decisions. We combined rainfall and periodicity data to provide an early warning signal of vole population growth in Mediterranean farmlands, a year in advance of a peak.

Malathion resistance in Spanish field populations of Ceratitis capitata is associated with a point mutation (R allele) and a heterogeneous duplication (RS haplotype) of the Ccace2 gene. The R allele imposes a higher fitness cost than the RS haplotype under laboratory and field conditions. An evolutionary model supports the stability of the RS haplotype

This study proposes an automated method to infer brown bear hair snare interactions by detecting bipedal behavior in camera‐trap images using a pose estimation model and a multilayer perceptron (MLP). A YOLO‐based model, fine‐tuned from humans and dogs to a custom dataset, achieved high performance (≈93% keypoint precision and ≈96% classification ...

We demonstrate that high‐resolution multispectral imagery combined with machine learning can accurately predict key biocrust functional indicators, particularly the UV‐protective pigment scytonemin, across dryland ecosystems. Using fine‐scale imagery acquired in the Chihuahuan Desert and Colorado Plateau, we identified spectral bands strongly ...
