Ecology of declining populations of gray foxes (Urocyon cinereoargenteus) in Indiana, USA Ecología de las poblaciones en declive de zorros grises (Urocyon cinereoargenteus) en Indiana, EE.UU.

Wildlife Monographs, EarlyView.
We estimated seasonal space use, cover selection, and resource selection; evaluated gene flow and potential genetic barriers; and assessed cause‐specific survival rates and reproduction of radiomarked gray foxes in Indiana, USA. Our results provide evidence that gray foxes in Indiana are an edge species with relatively large home ranges, relatively low

Calibration of Low-Cost Moisture Sensors in a Biochar-Amended Sandy Loam Soil with Different Salinity Levels

Sensors
With the increasing focus on irrigation management, it is crucial to consider cost-effective alternatives for soil water monitoring, such as multi-point monitoring with low-cost soil moisture sensors. This study assesses the accuracy and functionality of

“Alien versus predator”: predatory effect of coccinellid Exochomus quadripustulatus on the scale insect Toumeyella parvicornis. An open‐field experimentation on the Pinus pinea of Rome

Insect Science, EarlyView.
The release of gravid Exochomus quadripustulatus females proved to be effective in containing Toumeyella parvicornis infestations on stone pine trees, under open‐field condition. The ladybugs caused a lower infestation level compared to the trees that did not receive any ladybugs during the observation season.

Impact of food scarcity on the foraging dynamics of Eriopis connexa (Germar, 1824) (Coleoptera: Coccinellidae) Impacto da escassez de alimentos na dinâmica de forrageamento de Eriopis connexa (Germar, 1824) (Coleoptera: Coccinellidae)

Agricultural and Forest Entomology, EarlyView.
Starvation duration alters predatory behaviour of Eriopis connexa, affecting aphid consumption and survival dynamics. Increased starvation enhances attack rate, accelerating prey depletion without substantially affecting handling time. Functional response remains type II, with stronger predation under prolonged food deprivation.

Optimizing Citrus aurantifolia (Christm. Swingle) Production Through Integrated Irrigation and Growth Regulation Strategies

Agronomy
Optimizing irrigation and the targeted use of plant growth regulators are key strategies to improve productivity in citrus systems under water-limited conditions. This study evaluated the effects of three irrigation levels (4.44, 5.18, and 7.77 mm day−1)
