553	Beaver Movements On Managed Land In The Southeastern United States McClintic, Lance Forest 11 May 2013 (has links) I studied movement characteristics and vegetative resources effects on home range size of beavers at Redstone Arsenal (RSA) in north central Alabama, USA. Beavers were captured and radio tagged from 11 wetlands during winter and spring of 2011. I monitored movements of radio-tagged beavers using radio telemetry from May 2011–April 2012. Beavers moved faster, presumably more favorable to central place foraging, in wetland as they proceeded farther away from the central place, but did not in upland. Additionally, distributions of hourly distances from lodges were bimodal. Home range, core areas, and distance from lodge did not differ between age classes. Home range sizes increased with increasing habitat productivity and resource dispersion, whereas home ranges decreased with temporal variation in resources throughout the year. Quantity and spatial distribution of resources and patterns of foraging behavior influence movements and home ranges of central place foragers. resource heterogeneity resource dispersion habitat productivity NDVI normalized difference vegetation index core use area home range central place foraging castor canadensis beaver
554	Population Size, Habitat Use and Diet of Kittlitz's Murrelets in Prince William Sound, Alaska Allyn, Andrew J 01 January 2012 (has links) (PDF) During the summer of 2008 and 2009, we studied the ecology of the Kittlitz’s Murrelet (Brachyramphus brevirostris), a small diving seabird and candidate for the U.S. Endangered Species List, in Prince William Sound (PWS), Alaska. At-sea survey data suggests that the population significantly increased from 2001 to 2009, however there is limited evidence of reproductive success. Habitat use models showed individuals were observed in shallower waters, closer to glaciers, the shoreline, and further from moraines than the available habitat during the daytime. Finer extent sampling from 2008 suggests temperature-depth profiles also influence Kittlitz’s Murrelet daytime habitat use. The associations between Kittlitz’s Murrelets and water column characteristics are likely an effect of prey availability. Stable isotope work in 2009 suggests birds were generalist foragers prior to the breeding season, becoming more specialized following the breeding season. This specialization may have been a response to strict foraging constraints during the flightless fall molt. Time budgets of radio-tagged individuals suggest birds may have been responding to ephemeral prey concentrations, and working near their maximum energetic limits. Remote monitoring of radio-tagged individuals showed birds left the glacial fjord system during the nighttime, possibly spending these hours near gillnet fishing areas, suggesting a new possible area of concern in evaluating potential threats to Kittlitz’s Murrelet populations.

555	Exploring the phenomena “foraging” in urban green spaces : examples from Järva City District and Stockholm County / Utforskande av fenomenet att samla och plocka i urbana grönområden : exempel från Järva och Stockholm Moum Rieser, Anja January 2020 (has links) As cities globally experience rapid urbanization, the pressure on urban green areas increases and simultaneously opportunities for human-nature interactions decrease, which are crucial for urban citizens’ wellbeing. Urban foraging- the gathering of plant or fungal materials in urban areas- is a common human-nature interaction that has been inadequately studied and overlooked in urban policy, planning, and design. The objective of this thesis is to gain insights into the practices, motivations, and barriers of foragers in Järva City District and Stockholm County. Through an exploratory mixed methodology approach, this study demonstrated that urban foraging is perceived as a recreational activity that motivates people to get out in nature and connects them to biodiversity in forests and parks within the city. Foraging links people to high quality and local food and encourages the sharing of local ecological knowledge. Foragers investigated display care for nature, indicating that foraging can nurture a bond between nature and urban citizens. The expressed barriers to foraging were time, proximity, lack of knowledge, and fear of pollution. The findings show that foraging provides various benefits for citizens in Stockholm County and Järva City District, implying that urban foraging should not be overlooked in future research and assessments, and should be considered and incorporated into urban policy, planning, and design. / Green Access biocultural diversity public food urban foraging urban green spaces urban green commons wild food Social Sciences Interdisciplinary Environmental Sciences Miljövetenskap

557	Time-Memory Behavior Yields Energetically Optimal Foraging Strategy in Honey Bees. Van Nest, Byron N. 08 May 2010 (has links) (PDF) Classical experiments on honey bee time-memory showed that foragers trained to collect food at a fixed time of day return the following day with a remarkable degree of time-accuracy. A series of field experiments revealed that not all foragers return to a food source on unrewarded test days. Rather, there exist two subgroups: "persistent" foragers reconnoiter the source; "reticent" foragers wait in the hive for confirmation of source availability. A forager's probability of being persistent is dependent both on the amount of experience it has had at the source and the environmental conditions present, but the probability is surprisingly high (0.4-0.9). Agent-based simulation of foraging behavior indicated these high levels of persistence represent an energetically optimal strategy, which is likely a compromise solution to an ever-changing environment. Time-memory, with its accompanying anticipation, enables foragers to improve time-accuracy, quickly reactivating the foraging group to more efficiently exploit a food source. agent-based model social insects food-anticipatory activity foraging Apis mellifera time-memory Behavior and Ethology Ecology and Evolutionary Biology Entomology Life Sciences
