Responses Of The Florida Mouse (podomys Floridanus) To Habitat Management
… its status as a species that is threatened by habitat loss statewide. Publicly owned lands offer protection for the species, but management is generally focused on protecting biodiversity in general and not a particular species. The response of the Florida mouse to land management practices …

Influence of physical habitat management strategies on sportfish and food-web processes
The addition of habitat structures is a popular management strategy in reservoirs meant to mitigate the negative effects of passive and anthropogenic physical habitat degradation on sportfish populations and angler harvest and satisfaction. However, mechanisms linking the direct effect of habitat …

Impacts of habitat management on translocation of the rare terrestrial herb Platanthera integrilabia
… in situ and are most effective when species habitat requirements are well understood. Platanthera integrilabia is a rare terrestrial orchid endemic to the southeastern United States, and limited research has been done to investigate suitable habitat for this species, despite evidence …

Evaluation and Use of Stream Temperature Prediction Models for Instream Flow and Fish Habitat Management
… selecting a model to assess alternative water management scenarios was based on model capabilities. The RQUAL model, used to predict SRT temperatures under alternative hydropower release regimes, illustrated potential thermal habitat improvement for brown trout (Salmo trutta) compared to …

Response of Vegetation and Endangered Waterbirds to Habitat Management Techniques at Kealia Pond National Wildlife Refuge
<p>Habitat selection, reproductive effort, and habitat utilization of Hawai’ian stilts (Himantopus mexicanus knudseni) and Hawai’ian coots (Fulica alai) was studied on Kealia Pond National Wildlife Refuge in Mau’i, Hawai’i. Nesting behavior was confirmed following management treatments on the …

The effect of habitat management on biodiversity and ecosystem functions in oil palm plantations in Sumatra, Indonesia
… losses of biodiversity and increased pollution. Management interventions to mitigate these impacts are clearly needed. Oil palm is capable of supporting a dense understory with vegetation that can reach several metres high. However, some plantation owners completely remove this by spraying …

A model to understand population decline of the Devil's Hole pupfish (Cyprinodon diabolis) and support habitat management decisions
… recent decline and identify and test potential management strategies and policies to reverse or stop the deCline The model and modeling process was used to identify critical gaps in existing data. Tests simulating pore space manipulation, algae removal and addition of refugia fish resulted in …

EFFECTS OF SCALE AND HABITAT MANAGEMENT ON GRASSLAND BIRD RESPONSE IN CONSERVATION RESERVE PROGRAM FIELDS IN NORTHWEST ILLINOIS
… to multiple scales which encompass a spectrum of habitat variables, and the habitat scale of importance may depend on the response of interest. For practitioners, having knowledge of the effect of scale is useful because conservation efforts can be focused at the most appropriate scale. However, …

EFFECTIVENESS OF PRESCRIBED FIRE ON MEETING FUEL LOAD AND WILDLIFE HABITAT MANAGEMENT OBJECTIVES IN EAST TEXAS NATIONAL FORESTS
… Efficacy was determined by comparing defined management objectives established by the Forest Service to the data collected at the study sites. The results conclude that most objectives, as outlined by the Forest Service, are not being met with the current practices. Re-visitation of monitoring …

Estimating Forage Production for Waterbirds and Waterbird Response to Habitat Management at Lacreek National Wildlife Refuge, South Dakota
… to estimate waterfowl forage production on management units in order to meet habitat management goals. A technique was developed in Missouri to quickly estimate seed yields of common moist-soil plants consumed by a variety of waterfowl species by measuring phytomorphological measurements. …

Monkey beetles on the beat: urban monkey beetles reveal opportunities for pollinator habitat management in a South African city
… and relatively small interventions can provide habitat support in otherwise inhospitable urban landscapes. Despite this knowledge, there is a paucity of research on urban pollinators in Africa. This gap is noteworthy because Africa is a megadiverse region and southern Africa has three global …

Environmental differences in the microbiome and exposure to the emerging fungal pathogen, Emydomyces testavorans, in conservation rearing and release programs for the western pond turtle (Actinemys marmorata)
… and immune function. It is unknown if the management practices of built environments (e.g., disinfection, simplified substrates, full water changes) induce shifts to dysbiotic environmental and host-associated microbiomes that are susceptible to infection. We investigated the effect of the …

Regional Rarity: Consequences of Dispersal Limitation and Strategies for Reintroduction
… that limit species distributions within restored habitats has been a longstanding goal of restoration ecology, particularly with respect to differences between rare and widespread species. Numerous mechanisms have been proposed to contribute to rarity, including species traits, propagule …

Nutritional Value and Management of Waterfowl and Shorebird Foods in Atlantic Coastal Moist-Soil Impoundments
… documented for waterfowl, yet few evaluations of habitat management consider nutritional value of foods. I assessed 2 types of impoundment manipulation, using nutritional data as a basis for evaluation.Invertebrate and plant seed production were measured in disced and control plots in impoundments …

Maculinea arion as an indicator of rare niches in semi-natural acid grasslands in South West England and the role of Myrmica species of ant
Anecdotal evidence suggests that habitat management for the Large Blue butterfly, Maculinea arion, benefits other rare species. Selected plant and invertebrate species were monitored on a degraded site which was under going restoration management for the future re-introduction or natural …

An ecological study of the breeding birds of grassland habitats within Illinois
… vegetation structure, species interactions, and habitat management on community structure. Fragment size was found to strongly influence breeding bird species richness within grasslands. Non-prairie bird species dominated small grasslands whereas prairie bird species dominated large grasslands. …

DETECTION AND OCCURRENCE OF NERODIA HARTERI (SERPENTES: COLUBRIDAE) IN AN UPPER PORTION OF THE BRAZOS RIVER WATERSHED
… snakes are disproportionately impacted by habitat alteration adjacent to wetlands because of their reliance on both terrestrial and aquatic habitats. Brazos River Watersnakes, <em>Nerodia harteri</em>, are endemic natricines with one of the most restricted geographic ranges in North …

Habitat Selection of White-tailed and Mule Deer in the Southern Black Hills, South Dakota
… 1970's. This decline is believed to be due to habitat deterioration. Most habitats in the Black Hills are becoming ponderosa pinedominated climax communities. Such pine communities will not support as many deer as early successional vegetative stages. To better understand the declining …
