Mosquito traps designed to capture Aedes aegypti (Diptera: Culicidae) females: preliminary comparison of Adultrap, MosquiTRAP and backpack aspirator efficiency in a dengue-endemic area of Brazil

open access: yesMemorias do Instituto Oswaldo Cruz, 2008
In this report, the efficiency of Adultrap under field conditions is compared to a CDC backpack aspirator and to MosquiTRAP. An urban dengue-endemic area of Rio de Janeiro was selected to evaluate the efficiency of mosquito traps in capturing Aedes ...

The effect of metapopulation processes on the spatial scale of adaptation across an environmental gradient [PDF]

open access: yes, 2003
We show that the butterfly Aricia agestis (Lycaenidae) is adapted to its thermal environment in via integer changes in the numbers of generations per year (voltinism): it has two generations per year in warm habitats and one generation per year in ...

The phenology and population dynamics of Culicoides spp. in different ecosystems in the Netherlands [PDF]

open access: yes, 2008
The Netherlands has enjoyed a relatively free state of vector-borne diseases of economic importance for more than one century. Emerging infectious diseases may change this situation, threatening the health of humans, domestic livestock and wildlife.

Nanomaterial‐Based Inkjet Printing for Electrochemical Sensing

open access: yesSmall, EarlyView.
Inkjet printing provides a digitally controlled, versatile, and highly reproducible method for fabricating and functionalizing sensing devices. This Perspective highlights how homogeneous, material‐efficient deposition enables precise patterning of functional inks and scalable integration of sensors for chemical and biological detection. The discussion

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.

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.
