Reseeding Of Grazing Gastropods And Bivalves Into The Marine Environment In Western Australia, Jane Borg
Reseeding Of Grazing Gastropods And Bivalves Into The Marine Environment In Western Australia, Jane Borg
Fisheries management papers
The Department of Fisheries does not want to embark on what is ‘new territory’ in Western Australia without a policy framework to define what is to happen, why it is to happen, and what will happen if the project does or does not succeed. This paper therefore attempts to do three things. 1. It sets in place accepted definitions of reseeding and stock enhancement within the general context of fisheries management in Western Australia. 2. It discusses the policy issues associated with reseeding grazing gastropods and bivalves into the natural environment. 3. It proposes a framework or process to be …
Biological Synopsis Of The Black Bream, Acanthopagrus Butcheri (Munro) (Teleostei: Sparidae) In Western Australia With Reference To Information From Other Southern States, Jeffrey V. Norriss, J E. Tregonning, Rod C J Lenanton, Gavin A. Sarre
Biological Synopsis Of The Black Bream, Acanthopagrus Butcheri (Munro) (Teleostei: Sparidae) In Western Australia With Reference To Information From Other Southern States, Jeffrey V. Norriss, J E. Tregonning, Rod C J Lenanton, Gavin A. Sarre
Fisheries research reports
This synopsis presents a review of the literature and research to April 2001on the biology of black bream, Acanthopagrus butcheri (Sparidae), particularly in relation to Western Australian populations. A. butcheri is a commercially and recreationally important species, and is endemic to the coastal lakes, estuaries, river systems and sheltered coastal waters of southern Australia, including Tasmania. Separate stocks reside within each river/estuarine system in southwestern Australia, and there is considerable variation in feeding, growth rates and age at maturity among stocks. For rivers/estuaries that are seasonally flushed in winter, downstream movement with the flush is followed by the annual upstream …
Coyote Foraging Ecology, Vigilance, And Behavioral Cascades In Response To Gray Wolf Reintroduction In Yellowstone National Park, T. Adam Switalski
Coyote Foraging Ecology, Vigilance, And Behavioral Cascades In Response To Gray Wolf Reintroduction In Yellowstone National Park, T. Adam Switalski
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Vigilance behavior can aid in the detection of predators and may also play a role in observation of conspecifics, in food acquisition, and in the prevention of kleptoparasitism. However, in most occasions, vigilance is most important as an antipredator function. Generally, factors that increase the risk of predation also increase the amount of vigilance. We examined whether the reintroduction of the large predator, the wolf, in Yellowstone National Park (YNP) would influence coyote vigilance and foraging ecology. From December 1997 to July 2000, we collected 1743 h of coyote activity budgets. Coyote home ranges occurred within wolf territories (termed high-use …
Anting Behavior In Birds: Ant Selection And Effect Of Ant Chemistry On Feather Ectoparasites, Hannah Carrington Revis
Anting Behavior In Birds: Ant Selection And Effect Of Ant Chemistry On Feather Ectoparasites, Hannah Carrington Revis
Biological Sciences Theses & Dissertations
Active anting behavior occurs when songbirds apply ants to their feathers. During anting displays, a bird draws its wings forward in front of the head and swings its tail around to the far right or left. Both wing and tail feathers are then rubbed with ants held in the bird's beak. The potential associations among ants, feather ectoparasites and birds make anting behavior an important community-level interaction. Although this behavior is cosmopolitan in distribution and occurs in a wide variety of passerine birds, it remains poorly understood. This dissertation tested hypotheses about anting behavior through controlled experiments with captive songbirds …
Daft Plan Of Management For The Proposed Miaboolya Beach Fish Habitat Protection Area., Department Of Fisheries Western Australia
Daft Plan Of Management For The Proposed Miaboolya Beach Fish Habitat Protection Area., Department Of Fisheries Western Australia
Fisheries management papers
The aims of the proposal outlined in this draft management plan is to protect and rehabilitate the aquatic habitat of Miaboolya Beach, the associated mangrove ecosystem, and involve the community in their management. By setting the area aside as a FHPA, the Department of Fisheries will establish a framework to promote and actively conserve all the habitats within the Miaboolya system, as described in Section 3 of this document.

Effects Of Management Practices On Grassland Birds: Wilson’S Phalarope, Jill A. Dechant, Douglas H. Johnson, Lawrence D. Igl, Christopher M. Goldade, Amy L. Zimmerman, Betty R. Euliss
Effects of Management Practices on Grassland Birds
Information on the habitat requirements and effects of habitat management on grassland birds were summarized from information in more than 4,000 published and unpublished papers. A range map is provided to indicate the relative densities of the species in North America, based on Breeding Bird Survey (BBS) data. Although birds frequently are observed outside the breeding range indicated, the maps are intended to show areas where managers might concentrate their attention. It may be ineffectual to manage habitat at a site for a species that rarely occurs in an area. The species account begins with a brief capsule statement, which …
