eBird, a citizen-science program developed by the Cornell Lab of Ornithology and National Audubon, allows users to enter bird sightings from around the world in order to develop a large scale data set for research. This study seeks to analyze eBird data and methods in order to determine if the data collected is robust enough to be usable as a basis for habitat management and, if so, to what extent. This is accomplished through a comparison of Piping Plover (Charadrius melodus) (a threatened shorebird of management concern) counts, trends, and methodologies made through a survey following a strict protocol versus data collected by eBird in three different areas (Bolivar Flats, Apfel Park, and San Luis Pass). Using descriptive statistics such as mean counts, counts adjusted for effort, and frequency, and confirming with Kruskal-Wallis tests, variation was found between eBird and survey data. eBird contained lower counts of Piping Plovers and a lower sighting frequency than survey data. When adjusting counts as a function of effort, similar results were found. Piping Plovers were found not to occur frequently at Bolivar Flats (9 birds over 2 surveys), while Apfel Park and San Luis Pass showed similar but inconclusive results. This study ultimately determined that, while of great use on large scales, use of eBird data on the local level, should be used with caution. Further study should be done to investigate sources of variation and methods to increase the effectiveness of eBird on small scales.

<p> Breeding bird surveys were conducted on 7 properties belonging to 2 ranches in South Texas. Using these data I calculated temporal trends, and tested the effects of total May&ndash;April precipitation and cattle stocking rate on avian abundance. Trends were calculated for each ranch, the East Foundation and King Ranch, individually due to different range and wildlife management practices. Total avian abundance increased significantly on the 3 East Foundation properties between 2008 and 2015. During 39 breeding bird surveys, 16,441 individual birds of 88 species were recorded. Non-breeding bird surveys were also conducted on East Foundation properties, an increasing trend in total avian abundance was also calculated from these data. Total breeding bird abundance was stable on the 4 King Ranch properties between 2005 and 2013. A total of 19,162 individual birds of 87 species were recorded during 40 breeding bird surveys. The combined effect of livestock use and precipitation had a significant effect on total avian abundance on all King Ranch properties, and on the abundance of some individual species and groups. </p>

<p> Feral pigs (<i>Sus scrofa</i>) are one of the most ecologically harmful species in North America and are expanding across the U.S. at alarming rates. Feral pigs are an extremely prolific, destructive species and native ecosystems will continue to suffer unless resource managers intervene to reduce the damages caused by feral pigs. In 2015, in cooperation with the Texas Parks and Wildlife Department&ndash;Kerr Wildlife Management Area, I investigated the efficacy of several novel feral pig control prototype products (i.e., toxic baits) to: 1) compare lethality and length of intoxication times between 13 microencapsulated sodium nitrite (MESN) formulations in pseudo gavage dosed captive feral pigs; 2) evaluate residual sodium nitrite levels and potential risks of vomited MESN bait on non-target species; and 3) assess the lethality of 5 unique sodium nitrite formulations in group pen feeding trials. Pseudo gavage trials resulted in 4 MESN formulations achieving a 100% lethality rate with delayed emergence of intoxication symptoms compared to previous literature. Unexpectedly, gastric coatings delayed the onset of intoxication to the same degree as enteric coatings. Vomit appeared to be positively correlated with the delivery of a lethal dose of MESN paste bait as 55/56 pigs (98.21%) vomited and died. Residual sodium nitrite in vomited bait was 90% less than the sodium nitrite concentrations in the delivered paste matrix. Despite this reduction, vomited bait could serve as a potential threat to non-target and secondary consumers, although the degradation time, residual persistence, and probability of non-target vomit consumption remains unknown. Group pen trials, testing 5 unique sodium nitrite formulations, resulted in ?80.95% overall lethality, with the greatest individual formulation lethality equaling 96.77%. Results from these studies will be beneficial in determining a MESN feral swine toxicant formulation for registration with the United States Environmental Protection Agency in the future.</p>

<p> Globally, amphibians have suffered dramatic population declines in the past twenty years with habitat destruction implicated as the primary threat. The Natural Resources Conservation Service&rsquo;s Wetlands Reserve Program (WRP) restores wetlands on marginal agricultural land and is a means to restore the spatio-temporal wetland habitat required by amphibians to prevent, reverse, or stabilize declining population trends. The goal of WRP is &ldquo;to achieve the greatest wetland functions and values, along with optimum wildlife habitat, on every acre enrolled in the program.&rdquo; Functions and values are defined as the hydrological and biological characteristics of wetlands. A key unanswered question is to what extent is this goal being achieved? Amphibians enable quantifying the WRP goal due to their life-history requirements and explicit incorporation of their habitat needs into WRP plans. My research goal was to determine if hydrological and biological wetland characteristics had been restored to WRP sites in the Lower Grand River basin, north-central Missouri, based on distribution, recruitment success, and relative species richness estimates for members of a regional species pool. I identified three design strategies applied to WRP sites over time: walk-away, maximize hydrology, and naturalistic; the latter emphasizing restoring process as well as structure; and evaluated if design strategy was a useful covariate for restoration efforts. I encountered 10 amphibian species representing 59% of the regional species pool. Design strategy was not a predictive site-level covariate as sites within all three design strategies had varying hydrological wetland conditions resulting in greater habitat heterogeneity than anticipated on maximize hydrology and walk-away sites and less than anticipated on naturalistic sites. Amphibian detections occurred across all sites resulting in no difference among design strategy as the degree of heterogeneity in habitat conditions at the within site-scale demonstrated that amphibians were responding to ecological conditions that occur at a finer resolution than site. Results, irrespective of design strategy, indicate seven of the detected species or groups were widely- distributed, two were moderately- distributed, and two were sparsely distributed on WRP sites indicating hydrological wetland characteristics have been restored to sites given the moderate- to wide-distribution of species associated with both seasonal and permanent wetlands. Although species were successfully recruiting young into adult populations, only leopard frogs had high estimates of recruitment success whereas the remaining species had moderately high to moderate to low recruitment estimates indicating biological wetland characteristics are somewhat lacking to lacking for these species. Results from the relative species richness assessment indicate that, whereas 74% of the sites provided some degree of wetland habitat for members of the regional species pool over the course of the field season (7 March &ndash; 19 September), 52% of the sites lacked suitable habitat conditions during the peak of amphibian breeding and larval development (May through July). Targeting management actions that result in suitable seasonal wetland habitat conditions (shallow, vegetated wetlands that gradually dry by mid-to late-summer) throughout the time needed for species to complete their life history requirements is one method to increase the biological wetland value of restored WRP sites. Results show the value of WRP at conserving and restoring river-floodplain amphibians; however, achieving optimum wildlife habitat on every enrolled acre will be difficult at a site-level scale as habitat requirements, although overlapping, vary widely for the full range of species. Providing for all species in the regional species pool requires sites that transverse both the longitudinal and lateral floodplain gradient. If WRP is to realize its full potential, there must be recognition that optimum wildlife habitat can be defined at multiple spatial and temporal scales that match the landscape setting. Optimum wildlife habitat at a wetland scale is not the same as optimum wildlife habitat at the floodplain scale. The intent of WRP is to convert marginal, flood-prone agricultural lands back into wetlands so enrollment of lands located outside the active floodplain may be impracticable or unrealistic. Whereas attaining optimum wildlife habitat on every acre enrolled in the program may not be an achievable objective, providing optimum wildlife habitat for members of a regional species pool within an appropriately defined geography that includes both a longitudinal and lateral gradient represents an objective that is both desirable and attainable.</p><p>

This study was instigated by the lack of human dimensions research undertaken in New Zealand, and seeks to investigate the knowledge and values New Zealanders hold about New Zealand wildlife within three distinct groups of the New Zealand public. These groups were the Royal Forest and Bird Society of New Zealand Inc, the New Zealand Ecological Society (Inc.), and the New Zealand Deerstalkers Association. A questionnaire administered via Association list-serv's was utilised and a total of 52 questionnaires were completed by members of the three stakeholder groups. These were then analysed to investigate the values and knowledge New Zealanders hold toward wildlife in New Zealand. The findings of this study suggest that New Zealander's hold strong utilitarian and negativistic values toward wildlife while the humanistic, moralistic, and naturalistic values were expressed by the majority of respondents. This result could be due to the high level of respondents who were from the New Zealand Deerstalkers Association. Conversely, whiled the data suggests that New Zealander's hold the ecologistic/scientific value only weakly, overall they have a high level of factual knowledge about wildlife. Because of this, it may be suggested that wildlife managers should generate education programmes that specifically address the negativistic value by making them imaginative and interesting. Demographic factors were found to be influential in the ways in which New Zealander's value wildlife and the knowledge they hold although these were not as significant as indicated by studies undertaken in other countries. The lowest levels of knowledge were shown by respondents who were over 60 years of age; and higher income levels corresponded with the negativistic value being held more highly. Several areas of this study showed transgressions from other studies undertaken overseas. Unlike other studies, which suggested that females hold the naturalistic value more strongly than males, this study showed that both males and females held the naturalistic value only weakly. This indicates that findings from studies conducted overseas may not be transferable to the New Zealand situation and therefore, for New Zealand managers to effectively incorporate human dimensions information in decision-making processes, human dimensions research must be undertaken in the New Zealand context. Furthermore, wildlife managers should not make assumptions based on other studies and communities as these can lead to ineffective communication and implementation of wildlife management policies and education programmes.
