Artificial nest experiment reveals inter-guild facilitation in duck nest predation
Global Ecology and Conservation, 2020 Predation is the most important factor limiting Northern Hemisphere duck nest survival. While most avian nest predators take only eggs, mammalian predators also pose mortality risks to incubating ducks.

Advanced Science, EarlyView.Comparative genomics of Gondwana‐diverged Pila and Pomacea reveals parallel evolution of aerial oviposition. Convergent chromosomal rearrangements reshape regulatory landscapes within topologically associating domains. Lineage‐specific gene family expansions and viral‐derived perivitelline proteins (PV1) underpin desiccation resistance.

Advanced Science, EarlyView.Whole‐genome analysis of 1,054 chickens reveals three ancestral sources (NWC, SYA, and SHF) with distinct temporal entry patterns into the Tibetan Plateau. Route‐specific selection scans, calibrated against a demographic null, suggest complementary functional enrichments—vascular homeostasis (NWC), calcium signaling and cardiac adaptation (SYA), and ...

Examining human–carnivore interactions using a socio-ecological framework: sympatric wild canids in India as a case study [PDF]
Royal Society Open Science, 2019 Many carnivores inhabit human-dominated landscapes outside protected reserves. Spatially explicit assessments of carnivore distributions and livestock depredation patterns in human-use landscapes are crucial for minimizing negative interactions and ...

The Cost of a Nutritious Diet in Cafeterias: Evidence From US Military Dining Facilities
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Providing nutritious meals in institutional settings with financial constraints, such as military dining facilities, is challenging. The US Department of War (DoW) and US Department of Agriculture (USDA) collaborated to modernize the Basic Daily Food Allowance (BDFA) using an optimization model that incorporates service members' consumption ...

Feed depredation by European starlings
Kansas Agricultural Experiment Station Research Reports, 2009 Introduction European starlings (Sturnus vulgaris) were first introduced to the United States in the late 1800s. It is believed that the starlings were imported from Europe and released in New York City’s Central Park so that all of the birds mentioned in Shakespeare’s works would inhabit the new country.
