Designing the Future Deer Herd

'Designer' deer herds touted to help farmers April 20, 2021 New Zealand, rnz

... a range of factors that influenced where a deer wanted to forage, including its personality, health, social interactions, past experience, food availability and diet. Thompson said if those foraging behaviors were better understood, it might be possible to create herds with deer that were suited to specific farms...


A review of urban wildlife management from the animal personality perspective: The case of urban deer T Honda, H Iijima, J Tsuboi, K Uchida - Science of The Total Environment, 2018

... Studies have shown how the personalities of wildlife contribute to their adaptation to urban habitats. In order to prevent human-urban wildlife conflicts, recognizing the personalities of wildlife and selective culling of bold individuals should be conducted for deliberate selection for shyness when developing wildlife management plans...


Integrating evolution in the management of captive zoo populations [PDF]

AI Schulte‐Hostedde, GF Mastromonaco - Evolutionary Applications, 2015

... Both natural animal populations and those in captivity are subject to evolutionary forces. Evolutionary changes to captive populations may be an important, but poorly understood, factor that can affect the sustainability of these populations...


Genetic Diversity Issues


Phylogeography, population genetics and conservation of the European red deer Cervus elaphus FE Zachos, GB Hartl - Mammal Review, 2011

... Although hunting has an impact on red deer gene pools, the main threat today is habitat fragmentation in human-dominated landscapes. The resulting increase in genetic drift and inbreeding reduces variability in isolated populations and may lead to inbreeding depression. To support vital meta-populations, migration corridors should be established...


Modeling problems in conservation genetics using captive Drosophila populations: Improvement of reproductive fitness due to immigration of one individual into small partially inbred populations Derek Spielman, Dr. Richard Frankham. Zoobiology. 1992

... Immigration into small isolated captive and wild populations is recommended to alleviate inbreeding depression... These results indicate substantial benefits can be gained by the translocation of as few as a single animal between small, partially inbred populations ...


Genetic diversity and genetic similarity between urban and rural white‐tailed deer populations in Iowa. Whitney Briggs, Lynne Gardner & Julie Blanchong,

Department of Natural Resource Ecology & Management, Iowa State University

... Conclusions: High levels of diversity suggests no isolation of urban deer. Urban and rural populations are genetically similar. Implications: High rate of movement between urban and rural populations


Population Viability Analysis and Genetic Diversity of the Endangered Red Deer Cervus elaphus Population from Mesola, Italy Frank E. Zachos, et al © Wildlife Biology, NKV 2008

... we present a genetic analysis of 25 Mesola red deer ... A sensitivity analysis revealed that inbreeding depression and possible catastrophes had a huge impact on the population's prospects. However, the establishment of two subpopulations and successful attempts at reducing the consequences of catastrophic events were able to significantly mitigate the harmful effects of both inbreeding and environmental stochasticity...

Captive breeding programs for populations with a small number of founders

Katherine Ralls. Jonathan Ballou Trends in Ecology & Evolution. Volume 1, Issue 1, July 1986, Pages 19-22

... Small captive populations are likely to become extinct. Detailed breeding plans based on the principles of population genetics and demography can greatly increase their chances of long-term survival. Zoos have now begun to implement such plans but lack the resources to extend them to the many species that are likely to become extinct in the wild in the near future.


Migration to Improve Genetic Diversity


Female deer disperse farther than males, present disease-control challenge, Science Daily, June 28, 2016

... “Dispersal of female deer is density dependent, meaning that higher deer densities lead to greater dispersal rates.” He explained. “Therefore, reducing deer density will reduce female dispersal rates — and likely will reduce disease spread. Containing the spread of chronic wasting disease is going to be difficult when female deer disperse. Although not as many females disperse — 8 to 24 percent of females versus 50 to 75 percent of males — there end up being more of them, because they live longer than males and they disperse an average of 11 miles compared to 5 miles for males.”

When the herd is even, one buck for one doe, the dominant buck is going to be spreading his genes.” ...
