Anti‐Snake Ballistic Missiles: Explosions Trigger Immediate Movement in Snakes

Ethology, Volume 132, Issue 1, Page 67-71, January 2026.
Spalerosophis diadema snakes exhibited immediate movement responses to missile attacks accompanied by loud explosion noises during the military conflict between Israel and Iran. ABSTRACT Biodiversity and conservation are often the least noticed during armed conflicts. From October 1st, 2024, and again between June 13 and 24th, 2025, a brief but intense

Evidence of bovine viral diarrhea virus infection in three species of sympatric wild ungulates in Nevada: life history strategies may maintain endemic infections in wild populations

Frontiers in Microbiology, 2016
Evidence for bovine viral diarrhea virus (BVDV) infection was detected in 2009-10 while investigating a pneumonia die-off in Rocky Mountain bighorn sheep (Ovis canadensis canadensis), and sympatric mountain goats (Oreamnos americanum) in adjacent ...

Native and Alien Ungulates in North America: Potential for Restoring Herbivore Diversity and Functions

Global Ecology and Biogeography, Volume 35, Issue 1, January 2026.
ABSTRACT Aim Large herbivores play key roles in ecosystems by promoting plant diversity, dispersing seeds, regulating nutrient cycling, and shaping vegetation structure. Since the Late Pleistocene, their declines have led to profound ecosystem changes. While often viewed as problematic, alien herbivores may partly compensate for these losses; yet their

Dynamic Risk From Mexican Wolves and Mountain Lions Influences Elk Foraging Behavior

Ecology and Evolution, Volume 15, Issue 12, December 2025.
We observed elk foraging across a wolf risk gradient throughout all seasons and diel periods to quantify proportions of foraging, intense vigilance, and multitasking at the individual and herd levels. We quantified encounter and kill risk from Mexican wolves and mountain lions using habitat selection functions and utilization distributions.

Shared Bacterial and Viral Respiratory Agents in Bighorn Sheep (Ovis canadensis), Domestic Sheep (Ovis aries), and Goats (Capra hircus) in Montana

Veterinary Medicine International, 2011
Transmission of infectious agents from livestock reservoirs has been hypothesized to cause respiratory disease outbreaks in bighorn sheep (Ovis canadensis), and land management policies intended to limit this transmission have proven controversial.
