Towards Structured Planning And Learning At The State Fisheries Agency Scale, Caleb A. Aldridge Dec 2022

Towards Structured Planning And Learning At The State Fisheries Agency Scale, Caleb A. Aldridge

Theses and Dissertations

Inland recreational fisheries has grown philosophically and scientifically to consider economic and sociopolitical aspects (non-biological) in addition to the biological. However, integrating biological and non-biological aspects of inland fisheries has been challenging. Thus, an opportunity exists to develop approaches and tools which operationalize planning and decision-making processes which include biological and non-biological aspects of a fishery. This dissertation expands the idea that a core set of goals and objectives is shared among and within inland fisheries agencies; that many routine operations of inland fisheries managers can be regimented or standardized; and the novel concept that current information and operations can …

Adaptive Management And Quail Conservation On Rangelands In The American West, Leonard A. Brennan, Ashley Tanner, Evan P. Tanner Sep 2022

Adaptive Management And Quail Conservation On Rangelands In The American West, Leonard A. Brennan, Ashley Tanner, Evan P. Tanner

National Quail Symposium Proceedings

Adaptive management has been and is being practiced with the goal of sustaining populations of wild quails on large areas of rangelands in the American West. Because the current land use practices throughout most of the eastern two-thirds of the United States largely do not promote early-successional vegetation communities, rangelands contain the largest remaining blocks of contiguous (unfragmented) habitat for the northern bobwhite (Colinus virginianus) and the other 5 species of quails found in the western states. Many wildlife professionals on both private and public rangelands are practicing a diverse array of quail habitat and population management actions …

State And Transition Models In Space And Time – Using Stms To Understand Broad Patterns Of Ecosystem Change In Iceland, I. C. Barrio, D. S. Hik, T. A. Mulloy, J. Thorsson, K. Svavarsdóttir, B. Marteinsdóttir, I. S. Jónsdóttir Jan 2022

State And Transition Models In Space And Time – Using Stms To Understand Broad Patterns Of Ecosystem Change In Iceland, I. C. Barrio, D. S. Hik, T. A. Mulloy, J. Thorsson, K. Svavarsdóttir, B. Marteinsdóttir, I. S. Jónsdóttir

IGC Proceedings (1997-2023)

Managing ecological systems sustainably requires a deep understanding of ecosystem structure and the processes driving their dynamics. Conceptual models can lead to improved management, by providing a framework for organizing knowledge about a system and identifying the causal agents of change. We developed state-and-transition models (STMs) to describe landscape changes in Iceland over three historical periods with different human influence, from pre-settlement to present days. Our models identified the set of possible states, transitions and thresholds in these ecosystems and their changes over time. To illustrate the use of these models for predicting and improving management interventions, we applied our …
