Non-random dispersal in the butterfly Maniola jurtina: implications for metapopulation models [PDF]

open access: yes, 2000
The dispersal patterns of animals are important in metapopulation ecology because they affect the dynamics and survival of populations. Theoretical models assume random dispersal but little is known in practice about the dispersal behaviour of individual

A comparison of thermal drones and camera trap population estimates for Sitka black‐tailed deer in Alaska

open access: yesWildlife Biology, EarlyView.
One of the most difficult challenges for wildlife managers is reliably estimating wildlife populations. Camera traps combined with spatial capture–recapture (SCR) models are a popular tool for population estimation. They have limitations, however, including long data processing times.

Rhodamine-B for the mark, release, and recapture experiments in gamma-irradiated male Aedes aegypti (Diptera: Culicidae): Persistence, dispersal, and its effect on survival [PDF]

open access: yesVeterinary World
Background and Aim: Rhodamine-B (Rh-B) marking shows a great potential for use in mark-release-recapture (MRR) studies for rear-and-release mosquito control strategies, including the radiation-based sterile insect technique.

A high‐altitude thermal infrared method for estimating moose abundance and demography in Rocky Mountain National Park, USA

open access: yesWildlife Biology, EarlyView.
Resource managers require accurate estimates of large herbivore abundance and demography to maintain ecological integrity. Common methods to count these species, including observations from low altitude helicopter flights, may conflict with other protected area management objectives and struggle to produce precise estimates for more cryptic species. To

A comparison of linear transect and capture recapture methods results in Iranian Jerboa population density and abundance estimation in Mirabad plains, Shahreza

open access: yesیافته‌های نوین در علوم زیستی, 2019
During a period from spring 2008 till fall 2010, Iranian Jerboa population abundance was estimated using distance (linear transect) and capture-recapture methods in the Mirabad plains near Shahreza city in Isfahan Province.

Dispersal of Engineered Male Aedes aegypti Mosquitoes.

open access: yesPLoS Neglected Tropical Diseases, 2015
BackgroundAedes aegypti, the principal vector of dengue fever, have been genetically engineered for use in a sterile insect control programme. To improve our understanding of the dispersal ecology of mosquitoes and to inform appropriate release ...

Scientific Standards and the Regulation of Genetically Modified Insects [PDF]

open access: yes, 2012
Experimental releases of genetically modified (GM) insects are reportedly being evaluated in various countries, including Brazil, the Cayman Islands (United Kingdom), France, Guatemala, India, Malaysia, Mexico, Panama, Philippines, Singapore, Thailand ...

A framework for the ethical use of animal‐borne devices in post‐release monitoring following rehabilitation

open access: yesWildlife Biology, EarlyView.
Rehabilitation and release contribute to conservation efforts for threatened species. Ensuring that these efforts are effective requires a good understanding of the factors which determine survival and integration of released animals into wild populations.

Dispersal of the invasive pasture pest Heteronychus arator into areas of low population density: effects of sex and season, and implications for pest management

open access: yesFrontiers in Plant Science, 2016
African black beetle, Heteronychus arator (Scarabaeidae), is an exotic pest of pastures in northern New Zealand. Both adults and larvae feed on pasture grasses. Adults disperse by walking (short range) or flying (long range).
