NIMBioS short-term visitor Klaas Hartmann (Institute for Marine and Antarctic Studies, Univ. of Tasmania) will give two short talks this Thursday, September 20, from 1:30-2:30 p.m.
Time/Date: Thursday, September 20, 2012, 1:30 p.m.*
Location: Hallam Auditorium, Room 206, Claxton Building, 1122 Volunteer Blvd.
Speaker: Klaas Hartmann (Institute for Marine and Antarctic Studies, Univ. of Tasmania), NIMBioS short-term visitor
The talk will focus on two distinct topics:
Constructing a complete global bird phylogeny
Abstract: Phylogenetic trees frequently omit some extant species due to a lack of sequence data. These "missing" species are often non-randomly distributed in the tree, for example, due to the remote habitats of some clades. This non-random distribution can bias the insights gained from the phylogeny. We developed a methodology for combining multiple sources of data to enable inclusion of all known species (for the study group) in a distribution of trees. This methodology was applied to produce a global phylogeny of birds, revealing novel spatial and temporal patterns in distribution.
Managing fisheries for public benefit
Abstract: Much attention in fisheries management is focused on maximizing the net present value (NPV) of fisheries. However, the mechanisms most frequently used to achieve this (licences, ITQs etc.) generally result in fishery profits being distributed to the owners of these rights. But because fish stocks are a public resource, there is an expectation, often legislated, that fisheries should be managed to give the greatest benefit to the public — this is often not achieved by contemporary fisheries management. Methods for improving public benefit from fish stocks under existing management structures will be discussed.
