Population Growth Parameters of a Reintroduced Trumpeter Swan Flock , Seney
—Once an abundant and conspicuous presence in wetlands across much of north-central North America, Trumpeter Swan ( Cygnus buccinator ) poplulations were decimated in the midto late 1800s by a combination of market hunting, subsistence hunting, and habitat loss. Since then, restoration has focused primarily on reintroduction efforts in which captive-reared birds are released and then monitored....
متن کاملSeed-dispersal distributions by trumpeter hornbills in fragmented landscapes.
Frugivorous birds provide important ecosystem services by transporting seeds of fleshy fruited plants. It has been assumed that seed-dispersal kernels generated by these animals are generally leptokurtic, resulting in little dispersal among habitat fragments. However, little is known about the seed-dispersal distribution generated by large frugivorous birds in fragmented landscapes. We investig...
متن کاملApplying Cooperative Distributed Problem Solving Methods to Trumpeter Swan Management
We are developing a decision support system in an effort to assist biologists who are managing habitats for the Rocky Mountain population of trumpeter swans. Swan management is a domain that is ecologically complex, and this complexity is compounded by spatial and temporal issues. We are focused on providing decision support that allows managers to develop habitat management plans for local sit...
متن کاملOne Fish, Two Fish, Butterfish, Trumpeter: Recognizing Fish in Underwater Video
This paper presents a deformable template object recognition method for classifying fish species in underwater video. This method can be a component of a system that automatically identifies fish by species, improving upon previous works which only detect and track fish and those that rely on significant inter-species shape variations or special equipment. Our method works with video shot by a ...
متن کاملEmpirical Evaluation of Decision Support Systems: Concepts and an Example for Trumpeter Swan Management
Decision support systems are often not empirically evaluated, especially the underlying modelling components. This can be attributed to such systems necessarily being designed to handle complex and poorly structured problems and decision making. Nonetheless, evaluation is critical and should be focused on empirical testing whenever possible. Verification and validation, in combination, comprise...
