The data were collected from two localities of different altitudes and food supply. The locality on summits was covered mostly with grasses in herb layer and inhabited by chamois and red deer, while in the lower locations raspberry, forbs and broadleaved tree was abundant and red and roe deer were presented. The aim of the study was to analyze a feeding strategy of three ungulate species in mountain habitats with limited food supply and to deduce implications to management of their populations. (1) Botanic composition of the ungulate food was influenced not only by their foraging specialisation but also food supply was very important. Red deer consumed grasses (more than 90 percent of volume) on the summit in growing season while forbs and browse were presented in substantial amount in its diet in lower altitudes. (2) The food quality based on nitrogen content was higher in general in roe deer than in the others ungulates but during late winter the roe deer consumed the diet based on spruce needles of very low quality. The quality of red deer diet was lower in the summit area (grassy habitats) than at foot hills where the food supply was more various. (3) The roe deer distribution can be restricted by absence of high quality food resources in ground vegetation while red deer and chamois can use food of lower quality (grasses). (5) Winter is a critical period for all study species when the food supply is a worst quality and the ungulate diets were similar and the possibility of competition for limited resources increase.","PeriodicalId":89522,"journal":{"name":"Wildlife biology in practice (Online)","volume":"88 1","pages":"46-55"},"PeriodicalIF":0.0,"publicationDate":"2011-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84339221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One tool that resource managers in the United States use for managing, protecting, and conserving fragile marine resources is the designation of Marine Protected Areas. Presently, the public is concerned with the status and health of the fish and fisheries associated with the Flower Garden Banks National Marine Sanctuary (FGBNMS). Given these conservation and social issues, the main goal of this study was to provide an evaluation of the recreational fisheries associated with the FGBNMS. Findings showed that recreational landings were dominated by red snapper, vermilion snapper, and gray triggerfish; landings varied significantly by month and location. The highest fishing effort was in summer and the highest catch rates were in spring and fall; catch rates varied significantly by species and location in some areas. The mean weight of the primary recreational species taken was correlated negatively with time, but statistical similar. Proposed management measures for the FGBNMS are expected to impact some recreational fisheries, but long-term outcomes should benefit the Gulf of Mexico ecosystem.","PeriodicalId":89522,"journal":{"name":"Wildlife biology in practice (Online)","volume":"70 1","pages":"90-115"},"PeriodicalIF":0.0,"publicationDate":"2011-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75127330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We developed an expert system, based on expert interviews and literature analyses. We selected the most important site- and stand-related predisposing factors for bark peeling of red deer, considering the relation of food dependent and food independent settling stimuli. Within the mechanistic expert system, knowledge on predisposing effects of certain site and stand features is represented in the form of an award-penalty point system. In the current paper, we present the predisposition assessment system for bark peeling and the verification of the system with data of the inventory of natural resources of the Limestone Alps National Park (Upper Austria). \u0000Three site-related indicators, i.e. terrain features, roughness/smoothness of relief, and local climate, and six stand-related indicator, i.e. tree age, canopy cover, proportion of conifers, cover of herb layer, method of final cutting, and harassment, were included in the system. Both the chosen indicators and the overall assessment clearly reflected the predisposition in terms of relative frequencies of peeled and unpeeled sample plots. A supplemental logistic regression run with the occurrence/absence of bark peeling as response variable and the assessed predisposition scores from the PAS as explanatory variable proved the discriminatory value of the PAS.","PeriodicalId":89522,"journal":{"name":"Wildlife biology in practice (Online)","volume":"30 1","pages":"66-89"},"PeriodicalIF":0.0,"publicationDate":"2011-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74659861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To assess how elk (Cervus elaphus) and deer (Odocoileus spp.) were spatially distributed relative to roads and coal-bed natural gas well pads, we collected pellet group data during 2 summers in south-central Colorado. We used generalized linear mixed models to assess the relative probability of use of elk and deer in relation to roads and well pads. We found relative probability of use was positively associated with distance from roads, indicating greater use of areas farther away from roads. Relative probability of use was negatively associated with distance to well pads, potentially as a result of plant phenology and reseeding in disturbed areas around well pads. Other factors such as elevation, slope and vegetative security cover also influenced elk and deer spatial distributions. Based on these data, it appears resource use may be driven by forage and security cover more than disturbance features. Pellet group surveys appear to be an appropriate technique for evaluating resource use of populations across large spatial extents when logistical and financial constraints limit the use of more advanced technology such as very high frequency and global positioning system collars.","PeriodicalId":89522,"journal":{"name":"Wildlife biology in practice (Online)","volume":"1 1","pages":"32-40"},"PeriodicalIF":0.0,"publicationDate":"2011-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90355214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These owners were seen to manage their lands in a suboptimal manner resulting in low forest productivity relative to other ownership groups, leading to future timber supply problems. Over time these concerns lessened, but numerous federal forestry incentive programs still exist today to ensure family forest lands are \"properly\" managed. Since family forest owners control nearly two-thirds of American private forest land, this concern can be defended. Policies that impact the family forests will coincidentally often become important wildlife policies. The NIPF and family forest literature is examined to identify the transition in the NIPF problem from one centered solely on timber to one that considers the broader values of the forest, especially wildlife. This literature also describes many natural resource management relationships and policy tools that directly related to wildlife policy. The interaction of forest and wildlife policies is a fascinating aspect of the human dimension of wildlife. The literature review is extensive so that wildlife researchers will have a source to identify this important research resource.","PeriodicalId":89522,"journal":{"name":"Wildlife biology in practice (Online)","volume":"11 1","pages":"1-22"},"PeriodicalIF":0.0,"publicationDate":"2011-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72748002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
