Nursing Females Are More Prone To Heat Stress: Demography Matters When Managing Flying-Foxes For Climate Change, Stephanie T. Snoyman, Jasmina Munich, Culum Brown
Ecological Impacts of Climate Change Collection
Determining the underlying mechanisms responsible for species-specific responses to climate change is important from a species management perspective. The grey-headed flying-fox, Pteropus poliocephalus, is listed as vulnerable but it also a significant pest species for orchardists and thereby presents an interesting management conundrum. Over the last century, the abundance of the grey-headed flying-fox, P. poliocephalus, in Australia has decreased due to a variety of threatening processes but has increased in abundance in urban areas. These flying-foxes are highly susceptible to extreme heat events which are predicted to increase in the future under climate change scenarios. Exceptionally hot days result in …

Monitoring Standing Herbage Of The Sands And Choppy Sands Ecological Vegetation Types In The Nebraska Sandhills, Daniel W. Uresk
Monitoring Standing Herbage Of The Sands And Choppy Sands Ecological Vegetation Types In The Nebraska Sandhills, Daniel W. Uresk
Great Plains Research: A Journal of Natural and Social Sciences
A modified Robel pole with white and gray alternating bands (2.54 cm) was used to measure vegetation on sands and choppy sands ecological types in the Sandhills of Nebraska. Objectives were to determine the relationship between visual obstruction readings (VOR) and clipped standing herbage, develop guidelines for monitoring standing herbage, and provide sample size estimates. Visual obstruction measurements of standing herbage were linear, and regression coefficients were significant (P< 0.001) for 125 transects (R2 = 0.60, SE = 496 kg/ha). Clipped standing herbage ranged from 293 to 4389 kg/ha with a mean of 1,559 kg/ha. A minimum of four transects (20 stations/transect with four …

Peer Influence Of Non-Industrial Private Forest Owners In The Western Upper Peninsula Of Michigan, Jillian R. Schubert, Audrey L. Mayer
Peer Influence Of Non-Industrial Private Forest Owners In The Western Upper Peninsula Of Michigan, Jillian R. Schubert, Audrey L. Mayer
College of Forest Resources and Environmental Science Publications
Understanding how non-industrial private forest (NIPF) owners gain and share information regarding the management of their property is very important to policy makers, yet our knowledge regarding how and to what degree this information flows over privately owned landscapes is limited. The work described here seeks to address this shortfall. Widely administered surveys with close-ended questions may not adequately capture this information flow within NIPF owner communities. This study used open-ended questions in interviews of clusters of NIPF owners to determine whether and to what extent owners influence each other directly (through conversations or referrals to sources of advice) or …

Fisheries research reports
The commercial fishery is managed in three zones: south of latitude 30°S (Zone C), north of latitude 30°S (Zone B) and a third offshore zone (Zone A) around the Abrolhos Islands (Figure 1.3). Effort is evenly split between the southern and northern zones through the implementation of management controls aimed at addressing zone-specific issues. These issues include different maximum size restrictions and seasonal opening and closing dates. This report focuses on the state of the western rock lobster ecology at the date of publication.
Monitoring Standing Herbage Of Mid-Grass Prairie On The Fort Pierre National Grassland, South Dakota, Daniel W. Uresk
Monitoring Standing Herbage Of Mid-Grass Prairie On The Fort Pierre National Grassland, South Dakota, Daniel W. Uresk
The Prairie Naturalist
Monitoring vegetation with a modified Robel pole on the Fort Pierre National Grassland was evaluated for combined shallow clay and loamy overflow ecological sites (dominated by warm-season grasses), and for clayey ecological sites (dominated by cool-season grasses). My objectives were to 1) develop a relationship between visual obstruction readings (VOR) and standing herbage, 2) provide guidelines for vegetation monitoring, and 3) evaluate vegetation monitoring during the growing season for clayey ecological sites. The relationship between visual obstruction readings and standing herbage was linear and regression coefficients were highly significant (P < 0.001) for both ecological types. Cluster analyses for shallow clay and loamy overflow ecological sites grouped the VOR and standing herbage (kg•ha-1) into 4 resource categories. Monitoring with 4 transects will provide adequate information to estimate standing herbage within 259 ha (1 section). Three resource categories (VOR + herbage) for clayey ecological sites were defined by cluster analyses. Monitoring with 4 transects was determined to provide reliable estimates of standing herbage. July validation of vegetation with the developed clayey ecological site model will provide reliable monitoring of standing herbage from July through November for this ecological site.

Species composition, seasonality and distribution of immature fly populations on a southern Queensland feedlot during 2001–2003 were determined. Similar data were collected on feedlots in central New South Wales and central Queensland. The fly species recovered in the highest numbers were Musca domestica L. (Diptera: Muscidae), Stomoxys calcitrans L. (Diptera: Muscidae) and Physiphora clausa Macquart (Diptera: Ulidiidae). Houseflies were the dominant species at all feedlots. Houseflies preferred the warmer months from October to June, but stable flies preferred the cooler months and peaked in spring (September–November) and autumn (March–May). Larval abundance ratings recorded in the feedlot and numbers of larvae …

Department of Plant Pathology: Faculty Publications
The purpose of this review is to highlight key developments in nematode ecology from its beginnings to where it stands today as a discipline within nematology. Emerging areas of research appear to be driven by crop production constraints, environmental health concerns, and advances in technology. In contrast to past ecological studies which mainly focused on management of plant-parasitic nematodes, current studies reflect differential sensitivity of nematode faunae. These differences, identified in both aquatic and terrestrial environments include response to stressors, environmental conditions, and management practices. Methodological advances will continue to influence the role nematodes have in addressing the nature of …
Using Bird Strike Information To Direct Effective Management Actions Within Airport Environments, Todd J. Pitlik, Brian E. Washburn
Using Bird Strike Information To Direct Effective Management Actions Within Airport Environments, Todd J. Pitlik, Brian E. Washburn
USDA Wildlife Services: Staff Publications
Wildlife--aircraft collisions (wildlife strikes) pose a serious safety risk to aircraft. Many bird species, especially gulls, are very difficult to manage within airport environments as many traditional methods (e.g., trap and remove from the airport) can be relatively ineffective due to the birds’ various activities on airports (e.g., feeding, loafing, and flying). Such challenges have greatly impacted the Los Angeles International Airport and the Van Nuys Airport, as documented through historical bird strike records collected since 1990. Using information contained in these bird strike records, USDA APHIS Wildlife Services personnel conducted strategic planning efforts to reduce the risk of bird …
Deer Mice (Peromyscus Spp.) Biology, Damage And Management: A Review, Gary W. Witmer, Rachael S. Moulton
Deer Mice (Peromyscus Spp.) Biology, Damage And Management: A Review, Gary W. Witmer, Rachael S. Moulton
USDA Wildlife Services: Staff Publications
The deer mouse is the most widely distributed and abundant small mammal in North America. They use a wide array of habitats, are very adaptable, and have a high reproductive potential. They play a number of roles in ecosystems, but can cause damage to orchards, forests, agriculture crops, and rangelands primarily through seed and newly-emerged seedling consumption. They also cause damage similar to house mice when they occupy buildings or other structures. Deer mice are important components in disease transmission especially of hantaviruses and Lyme disease. Damage reduction methods generally involve lethal control to reduce numbers using rodenticides and traps. …
Effects Of Turf Rolling And Soil Aeration On Rodent Populations, Gary W. Witmer, David Borrowman
Effects Of Turf Rolling And Soil Aeration On Rodent Populations, Gary W. Witmer, David Borrowman
USDA Wildlife Services: Staff Publications
Rodent populations at airports can cause human safety issues by attracting raptors which increases the risk of raptor-aircraft strikes. Various methods can be used to reduce rodent numbers, including trapping, poisoning, and habitat manipulation. Burrow disruption by turf rolling and soil aeration is a potential habitat manipulation method that could potentially reduce the carrying capacity for rodents. We tested this method at Kansas City International Airport, Missouri. We monitored the rodent populations in a control (untreated) area and in a nearby treated area where the turf was rolled and the soil aerated. We used grids of live traps to determine …

USDA Wildlife Services: Staff Publications
Double-crested Cormorants (Phalacrocorax auritus) have used central New York waters for breeding and stopover habitats during migration since 1984. In response to public concern over Oneida Lake, the United States Department of Agriculture Wildlife Services and the New York State Department of Environmental Conservation initiated an integrated research, management and monitoring program aimed at mitigating cormorant impacts to fisheries and other natural resources in 1998. The history of this program was reviewed and efforts to reduce negative impacts of the Double-crested Cormorant population in central New York described. Management was successful, as demonstrated by a substantial decrease in …

USDA Wildlife Services: Staff Publications
The New York State Department of Environmental Conservation initiated a Double-crested Cormorant (Phalacrocorax auritus) control program in the eastern basin of Lake Ontario to mitigate cormorant impacts in 1999. Key objectives included improving the quality of Smallmouth Bass (Micropterus dolomieu) and other fisheries, restoring the structure and function of the warmwater fish community and reducing cormorant impacts to nesting habitats of other colonial waterbird species. In eight years of intensive control, cormorant numbers declined, with a corresponding reduction in estimated fish consumption. Diversity and numbers of co-occurring waterbirds either increased or have not been shown to …

Losses to life and property from unplanned fires (wildfires) are forecast to increase because of population growth in periurban areas and climate change. In response, there have been moves to increase fuel reduction—clearing, prescribed burning, biomass removal and grazing—to afford greater protection to peri-urban communities in fire-prone regions. But how effective are these measures? Severe wildfires in southern Australia in 2009 presented a rare opportunity to address this question empirically. We predicted that modifying several fuels could theoretically reduce house loss by 76%–97%, which would translate to considerably fewer wildfire-related deaths. However, maximum levels of fuel reduction are unlikely to …

Aim: The aim of this study was to identify the enablers and barriers to guideline implementation in a primary healthcare setting by employing the Promoting Action on Research Implementation in Health Services (PARIHS) framework as a template for data analysis and interpretation. Background: The use of clinical practice guidelines is pivotal to improving health outcomes. However, the implementation of guidelines into practice is complex, unpredictable, and, in spite of much investigation, remains resistant to explanation of what works and why. Optimising the enablers and minimising the barriers to implementation of a guideline for reducing cardiovascular disease risk has the potential …

The Management Of Feral Pig Socio-Ecological Systems In Far North Queensland, Australia, Gabriela Shuster
Antioch University Dissertations & Theses
The development of management programs for socio-ecological systems that include multiple stakeholders is a complex process and requires careful evaluation and planning. This is particularly a challenge in the presence of intractable conflict. The feral pig (Sus scrofa) in Australia is part of one such socio-ecological system. There is a large and heterogeneous group of stakeholders interested in pig management. Pigs have diverse effects on wildlife and plant ecology, economic, health, and social sectors. This study used the feral pig management system as a vehicle to examine intractable conflict in socio-ecological systems. The purpose of the study was …
