.Environmental Guidance Note for Disaster Risk Reduction: Healthy Ecosystems for Human Security and Climate Change Adaptation

Description: This publication was developed to provide guidance on the benefits of and ways to integrate environmental concerns into disaster risk reduction strategies (DRR) at the local and national levels. As recognised and outlined within the Hyogo Framework for Action priority 4, healthy ecosystems and environmental management are considered key actions in DRR. Although the field of disaster risk management has evolved to recognize the need for addressing sustainable development issues for reducing risk, the environmental dimension has not to date received adequate attention and practical guidance.

Protocol amending the 1916 Convention for the Protection of Migratory Birds : message from the President of the United States transmitting a protocol between the United States and Canada amending the 1916 Convention for the Protection of Migratory birds in Canada and the United States, with related exchange of notes, signed at Washington on December 14, 1995

Description: This treaty is an amendment between the United States and Canada to the statute making it unlawful to pursue, hunt, take, capture, kill or sell certain birds. The statute does not discriminate between live or dead birds and also grants full protection to any bird parts including feathers, eggs and nests.

Description: Ecosystem health with its near infinite number of variables is difficult to measure, and there are many opinions as to which variables are most important, most easily measured, and most robust, Bioassessment avoids the controversy of choosing which physical and chemical parameters to measure because it uses responses of a community of organisms that integrate all aspects of the system in question. A variety of bioassessment methods have been successfully applied to aquatic ecosystems using fish and macroinvertebrate communities. Terrestrial biotic index methods are less developed than those for aquatic systems and we are seeking to address this problem here. This study had as its objective to examine the baseline differences in ant communities at different seral stages from clear cut back to mature pine plantation as a precursor to developing a bioassessment protocol. Comparative sampling was conducted at four seral stages; clearcut, 5 year, 15 year and mature pine plantation stands. Soil and vegetation data were collected at each site. All ants collected were preserved in 70% ethyl alcohol and identified to genus. Analysis of the ant data indicates that ants respond strongly to the habitat changes that accompany ecological succession in managed pine forests and that individual genera as well as ant community structure can be used as an indicator of successional change. Ants exhibited relatively high diversity in both early and mature seral stages. High ant diversity in the mature seral stages was likely related to conditions on the forest floor which favored litter dwelling and cool climate specialists.

Understanding ecosystems

Description: Plants and animals live in environments which change over different periods of time. Some changes happen each year with the seasons, whilst others take hundreds or even millions of years. As these changes occur, living organisms respond in different ways. To cope with the changing seasons, individuals can change their physiology or behaviour, for instance by hibernating or migration. In response to longer-scale change, species may adapt through evolutionary change. If they cannot, they must either move away or become extinct.

Global Ocean Ecosystem Dynamics: Implementation Plan

Description: This document describes plans for the implementation of the Global Ocean Ecosystem Dynamics (GLOBEC) programme element of the International Geosphere-Biosphere Programme (IGBP). This Implementation Plan is an international response to the need to understand how global change, in the broadest sense, will affect the abundance, diversity and productivity of marine populations comprising a major component of oceanic ecosystems. The Plan describes the consensus view, developed under the auspices of the GLOBEC Scientific Steering Committee (SSC), on the research required to fulfill the scientific goals laid out in the GLOBEC Science Plan (IGBP Report No. 40). The Implementation Plan expands on the Science Plan, drawing on the results and recommendations of workshops, meetings, and reports thereof, that have been sponsored under the auspices of GLOBEC. The GLOBEC research programme has four major components which, are described in detail in this Implementation Plan; the research Foci, Framework Activities, Regional Programmes, and Integrating Activity. These are summarized in the Table of Contents, and in schematic diagrams within the text. They are the elements that have been planned by, and will be implemented under the auspices of, the GLOBEC SSC. National GLOBEC programmes may select those aspects of this international framework which are relevant to meeting national objectives, or they may develop new directions as needed to meet specific national needs.

Eddy covariance mapping and quantification of surface CO2 leakage fluxes

Description: We present eddy covariance measurements of net CO{sub 2} flux (F{sub c}) made during a controlled release of CO{sub 2} (0.3 t d{sup -1} from 9 July to 7 August 2008) from a horizontal well {approx}100 m in length and {approx}2.5 m in depth located in an agricultural field in Bozeman, MT. We isolated fluxes arising from the release (F{sub cr}) by subtracting fluxes corresponding to a model for net ecosystem exchange from F{sub c}. A least-squares inversion of 611 F{sub cr} and corresponding modeled footprint functions recovered the location, length, and magnitude of the surface CO{sub 2} flux leakage signal, although high wavenumber details of the signal were poorly resolved. The estimated total surface CO{sub 2} leakage rate (0.32 t d{sup ?1}) was within 7% of the release rate.
