Application of LANDSAT system for improving methodology for inventory and classification of wetlands [PDF]

open access: yes
The author has identified the following significant results. Processing of LANDSAT MSS data for detection of prairie ponds and lakes was completed. Data coverage included a 36,876 sq km area in southeastern North Dakota during May and July.

Home range and core area characteristics of urban and rural coyotes and red foxes in southern Wisconsin

open access: yesWildlife Biology, EarlyView.
Second‐order habitat selection is influenced by a variety of factors, including individual‐ and species‐specific traits and resource requirements, as well as landscape characteristics. By comparing home range characteristics across individuals, species, and landscapes, we can draw conclusions regarding whether and how different factors influence home ...

Spraying drones: efficacy of integrating an avian repellent with drone hazing to elicit blackbird flock dispersal and abandonment of sunflower fields

open access: yesWildlife Biology, EarlyView.
Multiple management strategies exist to combat bird damage to agriculture. We explored combining two tools, drones as frightening devices and an avian repellent, to assess effectiveness of an integrated method to deter large flocks on complex landscapes. We evaluated the ability of a spraying drone (DJI Agras MG‐1P) deploying Avian Control (i.e. active

Differences in mammal community response to highway construction across different levels of human land use

open access: yesWildlife Biology, EarlyView.
Worldwide, transportation agencies have been involved in road mitigation efforts to reduce road mortality and promote connectivity of endangered species. Baseline data on how mammals respond to highway construction, however, are rarely collected in road mitigation and monitoring studies, including in the USA.

‘Using anuran community diversity and Pseudacris crucifer to predict landscape quality across a land use gradient'

open access: yesWildlife Biology, EarlyView.
As human‐modified landscape and climate changes proliferate, maintaining biodiversity and understanding the function and quality of available habitat is imperative. As anurans (frogs/toads) such as Pseudacris crucifer, can be an indicator species of habitat quality and ecosystem productivity, studying the anuran community in a mixed‐land use region ...

Ground squirrel damage and control in Montana [PDF]

open access: yes, 1978
The Columbian ground squirrel (Spermophilus columbianus), Richardson ground squirrel (Spermophilus richardsoni), and blacktail prairie dog (Cynomys ludovicianus) cause millions of dollars of loss to Montana agriculture each year.

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.

Keystone effects of prairie dogs (Cynomys spp.) on grassland birds: Current knowledge and future directions

open access: yesConservation Science and Practice
Keystone species are critical to maintaining ecological relationships and ecosystem functioning around the world. Prairie dogs (Cynomys sp.) are a genus of colonial keystone species endemic to North American grasslands that modify bird community ...

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.
