Juvenile hormone‐mediated accelerated post‐flight recovery of ovarian development in Loxostege sticticalis (Lepidoptera: Crambidae)

New Plant Protection, EarlyView.
Flight in female beet webworms (Loxostege sticticalis) promotes an increase in feeding, thereby enhancing abdominal energy reserves. Following flight, the flight muscles undergo accelerated histolysis, and the energy substances undergoing histolysis are redirected to the ovaries. These two processes collectively promote ovarian development.

HyLPD Digital Twin Control for UAV Stability in High‐Wind Conditions

Optimal Control Applications and Methods, EarlyView.
This work introduces a novel HyLPD, a hybrid control framework combining Linear Quadratic Regulator (LQR) for baseline stability and Deep Deterministic Policy Gradient (DDPG) for adaptive compensation, tailored for UAVs under high‐wind conditions.

Bioclimatic, demographic and anthropogenic correlates of grizzly bear activity patterns in the Greater Yellowstone Ecosystem

Oikos, EarlyView.
Plasticity of diel activity rhythms may be a key element for adaptations of wildlife populations to changing environmental conditions. In the last decades, grizzly bears Ursus arctos in the Greater Yellowstone Ecosystem (GYE) have experienced notable environmental fluctuations, including changes in availability of food sources and severe droughts ...

Localizing Efforts to Prevent Sexual Exploitation and Abuse in Humanitarian Aid: Evolving Experiences of Power and Agency in Lebanon

Public Administration and Development, EarlyView.
ABSTRACT Efforts to address gender‐based violence in humanitarian settings increasingly call for recognition of and funding to local women‐led organizations and women's rights organizations for long‐term response. The Empowered Aid initiative seeks to address sexual exploitation and abuse by working with local organizations as well as the refugee women

Urban wild meat and pangolin consumption across southern forested Cameroon: The limited influence of COVID‐19

People and Nature, EarlyView.
Abstract Overexploitation of wildlife is pervasive in many tropical regions, and in addition to being a significant conservation and sustainability concern, it has received global attention given discussions over the origins of zoonotic disease outbreaks.

Large, rugged and remote: The challenge of wolf–livestock coexistence on federal lands in the American West

People and Nature, EarlyView.
Abstract The expansion of grey wolves (Canis lupus) across the western United States, including on public lands used for extensive livestock grazing, requires tools and techniques for reducing wolf–livestock conflict and supporting coexistence. We examined approaches used on forested lands managed by the U.S.

Biotechnology for Endangered Plant Conservation

2014
The rhythm of biodiversity loss is estimated to be between 1000 and 10,000 times higher than the natural extinction rate. This is often referred to as “the sixth extinction crisis” after the five known mass extinction events in geological history. Plant species are known to be particularly vulnerable to present biotic crisis.

Soil Microbiomes Underlie Population Persistence of an Endangered Plant Species

American Naturalist, 2019
Microbiomes can dramatically alter individual plant performance, yet how these effects influence higher-order processes is not well resolved. In particular, little is known about how microbiome effects on individual plants alter plant population dynamics,
