Regional coyote densities estimated from camera trapping covary with deer productivity, anthropogenic land use, and human–coyote conflicts

Wildlife Biology, EarlyView.
Density estimates assist conservation and management decisions. Unfortunately, management of elusive mesocarnivores occurring at low densities has often relied on qualitative metrics or population indices. The proliferation of camera trap sampling of wildlife provides an opportunity to apply recently developed methods for estimating density of unmarked

Relationship between seed harvesting method and seed physiological quality for a number of Pioneer maize hybrids [PDF]

, 2012
The seed germination and seed vigor of eight Pioneer Hi-Bred maize hybrids were evaluated immediately after harvesting and a year later. The aim was to determine whether the seed showed loss of germination and vigor when shelled mechanically.

A preventive strategy for the control of aphids in sweet pepper using lacewings and micrococcinelid beetles

Insect Science, EarlyView.
Aphids pose a serious risk to horticultural crops. Current biocontrol strategies often fail due to the poor establishment of natural enemies when aphids are scarce. We evaluated the potential of two aphidophagous predators, Micromus variegatus and Scymnus interruptus, to be used as preventive biocontrol agents, released before aphid infestation.

AutoPollS: A tool for automated monitoring of pollinators using deep learning

Methods in Ecology and Evolution, EarlyView.
Abstract Deep learning and computer vision hold enormous potential for automated monitoring of biodiversity, including pollinators and other insects. Efficient, scalable monitoring of insect pollinators is crucial given pollinators' role in supporting biodiversity and agricultural productivity amidst declining pollinator populations.

Food without fire: Environmental and nutritional impacts from a solar stove field experiment

American Journal of Agricultural Economics, EarlyView.
Abstract Over 80% of the population in rural Sub‐Saharan Africa relies on biomass cooking fuel, a substantial source of anthropogenic greenhouse gases. We use a field experiment in Zambia to investigate the impact of solar stoves on biomass fuel use and cooking habits.

Movement and Survival of Spodoptera litura (Lepidoptera: Noctuidae) Neonate Larvae on Cotton Expressing Bacillus thuringiensis Proteins

Entomologia Experimentalis et Applicata, EarlyView.
Spodoptera litura neonates showed increased movement on Bt‐expressing Bollgard 3 (BG) cotton leaf discs but did not initially avoid it. Survival was higher when larvae could move from BG3 to non‐Bt leaf discs. On whole plants, more larvae dispersed from hatching on BG3 cotton compared to non‐Bt cotton. These findings suggest the larval movement differs

The rps15-rpl32 intergenic locus is a phylogeographic marker for Latin American Zea mays landrace varieties and subspecies

BMC Genomics
Background Maize (Zea mays L.) has a deep cultural significance in Latin America, with traditional and native varieties cultivated for millennia. Approximately 220 maize races have been identified in the region.

Economic and Biological Evaluation of Pheromone Trap Types for Western Bean Cutworm, Striacosta albicosta, Monitoring in Dry Edible Bean Fields

Entomologia Experimentalis et Applicata, EarlyView.
Pheromone trap use for monitoring Striacosta albicosta in dry edible beans was evaluated across multiple trap designs, lure replacement intervals, and insecticide timings. Bucket traps captured the most moths, yet trap counts poorly predicted crop damage.

Forage Plant Host and Early Feeding Choices Affect Spodoptera litura Feeding, Development and Egg‐Laying

Entomologia Experimentalis et Applicata, EarlyView.
We assessed Spodoptera litura (Lepidoptera: Noctuidae) performance on five common pasture plant species. Larvae consumed more dock, plantain and chicory per day than red or white clover, but with lower conversion efficiencies. Feeding on red clover reduced weights and egg laying, and lengthened development times compared with plantain.

Pentatricopeptide repeat proteins in crops: Advances in functional mechanisms and breeding applications

Journal of Integrative Plant Biology, EarlyView.
Pentatricopeptide repeat proteins coordinate nucleus‐organelle communication by modulating RNA metabolism within chloroplasts and mitochondria. This review highlights how they control critical processes like photosynthesis, seed development, fertility restoration, and stress survival in crops, and explores their potential as programmable tools for RNA ...
