Wild Animal Suffering Is Not Intractable: A Precautionary Approach to Compassionate Intervention

Journal of Applied Philosophy, Volume 43, Issue 2, Page 471-490, May 2026.
ABSTRACT Wild animals suffer due to human activity, yet natural factors contribute far more significantly to their suffering. In light of this, some propose that we have a pro tanto obligation to intervene in ecosystems to improve wild animal welfare.

Administering GonaCon^TM to White-Tailed Deer Via Hand-Injection Versus Syringe-Dart

Human-Wildlife Interactions, 2017
Immunocontraceptive vaccines have shown some promise for fertility control of white-tailed deer (Odocoileus virginianus) in urban and suburban habitats where traditional methods of population control may not be applicable.

Understanding Why Grey Squirrels (Sciurus carolinensis) Bark Strip in British Woodlands: A Systematic Map

Mammal Review, Volume 56, Issue 1, March 2026.
Studies investigating the bark‐stripping behaviour of squirrel species that cause economic damage focus on developing methods to manage the behaviour. On the other hand, studies investigating the behaviour of species that do not cause economic damage focus on understanding the behavioural ecology of the species to meet conservation objectives.

Investigating the potential of RFID in identifying individual white-tailed deer for PZP immunocontraceptive programs

Frontiers in Conservation Science
IntroductionIdentifying individual white-tailed deer (Odocoileus virginianus) for treatment with porcine zona pellucida (PZP) immunocontraceptive vaccines is critical to the success of fertility management programs, but adult female deer are very ...

Foaling rates in feral horses treated with the immunocontraceptive porcine zona pellucida

Wildlife Society Bulletin, 2011
Locally abundant feral horses (Equus caballus) can rapidly deplete available resources. Fertility control agents present promising nonlethal tools for reducing their population growth rates.

Twenty Years of SpayVac® Research: Potential Implications for Regulating Feral Horse and Burro Populations in the United States

Human-Wildlife Interactions, 2018
There are currently >75,000 feral horses (Equus ferus caballus) and burros (E. asinus ) on U.S. public lands, yet the Appropriate Management Level (AML) is set at just under 27,000.

General mechanisms for a top–down origin of the predator–prey power law

Oikos, Volume 2025, Issue 9, September 2025.
The ratio of predator‐to‐prey biomass density is not constant along ecological gradients: denser ecosystems tend to have fewer predators per prey, following a scaling relation known as the ‘predator–prey power law'. The origin of this surprisingly general pattern, particularly its connection with environmental factors and predator–prey dynamics, is ...

The projected Phinda elephant population divided into age classes represented as absolute numbers under different immunocontraception scenarios.

, 2013
The age classes are classified as 0–2 years: infant, 2–4 years: juvenile, 5–8 years: intermediate, 9–12 years: sub-adults, older than 13 years are classified as an adult.

Efficacy of SpayVac® as a contraceptive in feral horses

Wildlife Society Bulletin, 2017
We tested the efficacy of 2 formulations of the immunocontraceptive SpayVac®, which packages the immunogen porcine zona pellucida (PZP) and an adjuvant in multilamellar liposomes, as a contraceptive in captive feral horses (Equus caballus) for 3 ...

Demographics of Non-Hunted White-Tailed Deer Populations in Suburban Areas

Human-Wildlife Interactions, 2017
Burgeoning deer populations in urban and suburban areas, along with the inherent problems stemming from this increase, are becoming increasingly widespread. To address these problems, wildlife biologists need quality baseline data of herd composition for
