Adaptive harvest management for the Svalbard population of pink-footed geese: briefing summary Adaptive harvest management for the Svalbard population of pink-footed geese: briefing summary

The African-Eurasian Waterbird Agreement (AEWA; http://www.unep-aewa.org/) calls for means to manage populations which cause conflicts with certain human economic activities. The Svalbard population of the pink-footed goose has been selected as the first test case for such an international species management plan to be developed. This document describes progress to date on the...

Emergent wetlands status and trends in the northern Gulf of Mexico: 1950-2010 Emergent wetlands status and trends in the northern Gulf of Mexico: 1950-2010

Throughout the past century, emergent wetlands have been declining across the Gulf of Mexico. Emergent wetland ecosystems provide many resources, including plant and wildlife habitat, commercial and recreational economic activity, water quality, and natural barriers against storms. As emergent wetland losses increase, so does the need for information on the causes and effects of this...

Unpaved road dust management, a successful practitioner’s handbook Unpaved road dust management, a successful practitioner’s handbook

This handbook provides broad programmatic aspects of unpaved road management. It is based on observations made during a national scan tour and provides useful and insightful excerpts of realworld examples and includes practical how-to instructions for determining what type of treatment may be needed for different situations. It ultimately strives to encourage road managers to think...

Application of ground-truth for classification and quantification of bird movements on migratory bird habitat initiative sites in southwest Louisiana: final report Application of ground-truth for classification and quantification of bird movements on migratory bird habitat initiative sites in southwest Louisiana: final report

This project was initiated to assess migrating and wintering bird use of lands enrolled in the Natural Resources Conservation Service’s (NRCS) Migratory Bird Habitat Initiative (MBHI). The MBHI program was developed in response to the Deepwater Horizon oil spill in 2010, with the goal of improving/creating habitat for waterbirds affected by the spill. In collaboration with the University...

ECALS: Loading studies interim report July 2013 ECALS: Loading studies interim report July 2013

Since the initial detection of Asian carp moving up the Mississippi Basin, the potential for invasion of the Great Lakes by Silver Carp and Bighead Carp has been a major concern to stakeholders. To combat this problem, sampling for environmental DNA (eDNA) is used to monitor the waterways near Lake Michigan. This monitoring area includes the Chicago Area Waterways System (CAWS) and the...

Changes to oak woodland stand structure and ground flora composition caused by thinning and burning Changes to oak woodland stand structure and ground flora composition caused by thinning and burning

Our objective was to quantify the cumulative effects of prescribed burning and thinning on forest stocking and species composition at a woodland restoration experiment site in the Ozark Highlands of Missouri. Our study used four treatments (burn, harvest, harvest and burn, control) on three slope position and aspect combinations (south, north, ridge) replicated in three complete blocks

Groundwater flow cycling between a submarine spring and an inland fresh water spring Groundwater flow cycling between a submarine spring and an inland fresh water spring

Spring Creek Springs and Wakulla Springs are large first magnitude springs that derive water from the Upper Floridan Aquifer. The submarine Spring Creek Springs are located in a marine estuary and Wakulla Springs are located 18 km inland. Wakulla Springs has had a consistent increase in flow from the 1930s to the present. This increase is probably due to the rising sea level, which puts...

Adaptive harvest management for the Svalbard population of pink-footed geese: cooperator report Adaptive harvest management for the Svalbard population of pink-footed geese: cooperator report

This document describes progress to date on the development of a harvest‐management strategy for maintaining pink‐footed goose abundance near their target level by providing for sustainable harvests in Norway and Denmark. Many goose populations in western Europe have increased dramatically in recent decades. The Svalbard population of pink‐footed geese (Anser brachyrhynchus) is a good...

TanA: a fluorogenic probe for thiaminase activity TanA: a fluorogenic probe for thiaminase activity

A fluorogenic thiamine analogue is presented as a fluorescent probe for thiaminase activity. The emission of the fluorophore is quenched by photoinduced electron transfer (PET) to the N-substituted pyridinium portion of the probe. Action of the enzyme releases the free pyridine group causing a substantial increase in fluorescence.
