  1. Combined Effects of Clime, Vegetation, Human-Related Land Use and Livestock on the Distribution of the Three Indigenous Species of Gazelle in Eritrea

    Full-text: Available

    | Contributor(s):: Hagos, Futsum, Yemane, Tecle, Ibrahim, Kamal M., Mangiacotti, Marco, Sacchi, Roberto

    The status and habitat selection of the three species of gazelle indigenous to Eritrea, i.e., Nanger soemmerringii, Gazella dorcas and Eudorcas tilonura, are not well known. In this study, we analyzed the present distribution of the three species in the country in order to identify preferred...

  2. Instagram as a data source for sea turtle surveys in shipwrecks in Brazil

    | Contributor(s):: Leitao, A. T. T. S., Alves, M. D. de O., Santos, J. C. P. dos, Bezerra, B.

  3. Environmental and training factors affect canine detection probabilities for terrestrial newt surveys

    | Contributor(s):: Grimm-Seyfarth, A.

  4. The Effects of Urbanization on Performance, Habitat Selection, and Persistence of Anolis Lizards

    Full-text: Available

    | Contributor(s):: Andrew Clark Battles

    Urbanization is a global change phenomenon that is increasing in frequency and magnitude worldwide. As a greater proportion of the human population resides in urban areas, cities must grow, therefore exposing an increasing number of species to human-modified habitat. While some species become...

  5. Testing artificial nestbox designs for in-situ conservation of tamarins

    | Contributor(s):: Ahsmann, Judith, Price, Eluned, Griede, Tine, Wormell, Dominic

  6. Spatial Design of Guest Feeding Programs and Their Effects on Giraffe Participation and Social Interactions

    | Contributor(s):: Ramis, Fatima, Mohr, Michaela, Kohn, Gregory, Gibson, Quincy, Bashaw, Meredith, Maloney, Dan, Maple, Terry

  7. Spatial and temporal plasticity in free-ranging dogs in sub-Antarctic Chile

    | Contributor(s):: Schüttler, Elke, Saavedra-Aracena, Lorena, Jiménez, Jaime E.

    Free-ranging owned dogs are a conservation concern worldwide, but knowledge on their movement ecology is only recently increasing. To examine unsupervised dog movements into wilderness, we attached Global Positioning System devices to 33 village and four rural dogs on a sub-Antarctic island in...

  8. Effects of the artificial reef and flow field environment on the habitat selection behavior of Sebastes schlegelii juveniles

    | Contributor(s):: Li, Jiajia, Li, Jiao, Gong, Pihai, Guan, Changtao

    With pollution and disturbances in marine ecological environments, the quality and structure of fish habitats in offshore regions have exhibited drastic decreasing trends. Artificial reefs are a vital engineering measure for restoring such degraded marine habitats. In this study, the quantitative...

  9. Post-release activity and habitat selection of rehabilitated black bears

    Full-text: Available

    | Contributor(s):: Patrick J. Myers, Julie K. Young

    Despite the long history of wildlife rehabilitation and the abundance of empirical knowledge of the behavior and resource selection of wildlife species, rarely does research bridge these disciplines. Such investigations could be of value to wildlife managers and rehabilitators by revealing the...

  10. Conserving Vermont's Endangered Species through Designation of Critical Habitat

    Full-text: Available

    | Contributor(s):: Amanda M. Ramsing-Lund

    Although the Endangered Species Act of 1973 is federal legislation, protection of threatened and endangered (T & E) species varies in stringency across states. H.570 (Act 145) is a Vermont law passed during the 2015-2016 legislative session that updated some of the legal protections for T...

  11. Efficacy of an interactive apparatus as environmental enrichment for common bottlenose dolphins (Tursiops truncatus)

    | Contributor(s):: Lauderdale, L. K., Miller, L. J.

  12. Zoo foraging ecology: development and assessment of a welfare tool for captive animals

    | Contributor(s):: Troxell-Smith, S. M., Whelan, C. J., Magle, S. B., Brown, J. S.

  13. An Evaluation of Systematic Versus Strategically-Placed Camera Traps for Monitoring Feral Cats in New Zealand

    Full-text: Available

    | Contributor(s):: Margaret Nichols, James Ross, Alistair S. Glen, Adrian M. Paterson

    We deploy camera traps to monitor feral cat (Felis catus) populations at two pastoral sites in Hawke’s Bay, North Island, New Zealand. At Site 1, cameras are deployed at pre-determined GPS points on a 500-m grid, and at Site 2, cameras are strategically deployed with a bias towards forest...

  14. Consistent behavioural responses to heatwaves provide body condition benefits in rangeland sheep

    | Contributor(s):: Leu, Stephan T., Quiring, Katrin, Leggett, Keith E. A., Griffith, Simon C.

  15. Cattle habitat selection and associated habitat characteristics under free-range grazing within heterogeneous Montane rangelands of Alberta

    | Contributor(s):: Kaufmann, Jillian, Bork, Edward W., Blenis, Peter V., Alexander, Michael J.

    The integration of multiple uses on public rangeland requires reliable information on patterns of livestock use. We used GPS data and field plot utilization indices to examine cattle selection at the landscape and patch levels, respectively, within a heterogeneous Montane environment of SW...

  16. Nest sharing under semi-natural conditions in laying hens

    | Contributor(s):: Riber, Anja Brinch

    Under natural conditions, the feral hen (Gallus gallus domesticus) will choose a nest location away from the flock, whereas under commercial conditions, the domestic hen will often choose the same nest as other hens have used or are still using. Simultaneous nest sharing causes several welfare...

  17. Movement in a confined space: Estimating path tortuosity

    | Contributor(s):: Miller, Curtis, Christman, Mary C., Estevez, Inma

    Tortuosity of an animal's path may be defined in the most general sense as departure of the path from straightness and is closely related to the animal‘s behavior. For example, movement toward a destination is straighter and hence less tortuous than foraging behavior where the animal is searching...

  18. Spatial and temporal activity of cattle grazing in Mediterranean oak woodland

    | Contributor(s):: Schoenbaum, Iris, Kigel, Jaime, Ungar, Eugene D., Dolev, Amit, Henkin, Zalmen

    We examined the temporal and spatial variation patterns of the grazing activity of free-ranging cattle in Mediterranean oak woodland in the Western Galilee, Israel, as affected by seasonal and management factors. The vegetation is dominated by scrub-oak woodland (Quercus calliprinos Webb.),...

  19. How you can help save the bees, one hive at a time | Noah Wilson-Rich

    Full-text: Available

    | Contributor(s):: Noah Wilson-Rich

    Bees are dying off in record numbers, but ecologist Noah Wilson-Rich is interested in something else: Where are bees healthy and thriving? To find out, he recruited citizen scientists across the US to set up beehives in their backyards, gardens and rooftops. Learn how these little data...

  20. Movement and home range of owned free-roaming male dogs in Puerto Natales, Chile

    | Contributor(s):: Pérez, Guillermo E., Conte, Annamaria, Garde, Elena J., Messori, Stefano, Vanderstichel, Raphael, Serpell, James

    Free-roaming dogs (FRDs) pose a significant health threat to humans, other animals and the environment. Yet, the effects of their movements and habitat use within cities and adjacent rural areas are poorly known, especially in relation to predation and the transmission of diseases that can impact...
