An Experimental Study on the Protective Effect of Memantine in Noise‐Induced Hearing Loss

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective This study examined the potential protective effects of memantine, an N‐methyl‐D‐aspartate (NMDA) receptor antagonist, against acoustic trauma (AT) in guinea pigs, using electrophysiological and histopathological analyses. Methods Thirty guinea pigs with normal hearing were divided into six groups (n = 5 per group): Group 1 (control),

Spraying drones: efficacy of integrating an avian repellent with drone hazing to elicit blackbird flock dispersal and abandonment of sunflower fields

open access: yesWildlife Biology, EarlyView.
Multiple management strategies exist to combat bird damage to agriculture. We explored combining two tools, drones as frightening devices and an avian repellent, to assess effectiveness of an integrated method to deter large flocks on complex landscapes. We evaluated the ability of a spraying drone (DJI Agras MG‐1P) deploying Avian Control (i.e. active

Experimental assessment of large mammal population estimates from airborne thermal videography

open access: yesWildlife Biology, EarlyView.
Wildlife resource management requires reliable, fast, and affordable methods of surveying wildlife populations to develop and adaptively adjust policies. Thermal video from drones can yield high rates of detection over large areas with relative speed and safety.

Wild Pigs (Sus scrofa) Stand Their Ground: Investigating Flight Response, or Lack Thereof, to Perceived Predation Risk 野猪坚守原地:探究其面对感知捕食风险时的逃逸反应 (或无逃逸行为)

open access: yesWildlife Letters, EarlyView.
We used automated behavioral response systems (ABRs) to assess invasive wild pig (Sus scrofa) behavioral response to four auditory playbacks: humans, coyote vocalizations (Canis latrans), pigs in distress, and barred owl (Strix varia) calls. Wild pigs had a significant flight response to human playbacks, but 68% of pigs did not flee.

Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range

open access: yesWildlife Society Bulletin, EarlyView.
We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.

Field evaluations of thermal optics and tracking tunnels for small mammal surveys at airports and grass dominated habitats

open access: yesWildlife Society Bulletin, EarlyView.
Small mammal survey tools are needed at airports to help inform aircraft strike‐risk management. We evaluated thermal optics and tracking tunnels as small mammal survey tools. We conclude that thermal optics would not be a viable survey tool for mouse‐sized mammals (19‐41 g) at airfields and other thick grass habitats unless grass height was maintained
