GnRH Single-Injection Immunocontraception of Black-Tailed Deer [PDF]

, 2006
High deer densities increase vehicle collisions, damage agricultural crops, and amplify the spread of zoonotic and animal diseases, intensifying human-deer conflict.

Effects of prolonged immunocontraception on the breeding behavior of American bison

Journal of Mammalogy, 2017
In late 2009, the Catalina Island Conservancy began using fertility control to replace periodic removals to manage an introduced population of American bison (Bison bison) on the island.

Effects of GonaCon immunocontraceptive vaccine in free‐ranging female Rocky Mountain elk (Cervus elaphus nelsoni)

Wildlife Society Bulletin, 2014
Duration of efficacy and prevalence of side‐effects associated with GonaCon Immunocontraceptive Vaccine (GonaCon) in free‐ranging female elk (Cervus elaphus) are unknown. In January 2008, we captured 120 mature female elk in Rocky Mountain National Park (

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.

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 ...

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.

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.

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 ...

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.
