Samoa 2012 Environmental Outlook : developing a vision for the next 50 years

Available Online

SPREP/MNRE/IAN

Samoas rich cultural heritage and future prosperity depends on a healthy environment. Over the past 50 years, Samoas environment has been pressured by increasing population and development, agricultural expansion, invasive species of plants and animals, and disasters such as tsunamis, cyclones, and fi res. Each of these threatens the health of our environment, thereby threatening the wellbeing of Samoan people and Fa Samoa our traditional way of life

The Ants of Fiji

Eli M. Sarnat

The ant fauna of the Fijian archipelago is a diverse assemblage of endemic radiations, pan-Pacific species, and exotics introduced from around the world. The Ants of Fiji describes the entire Fijian ant fauna, and includes the results of a recently completed archipelago-wide biodiversity inventory. A total of 187 ant species representing 43 genera are recognized here with an illustrated key to genera, synopses of each species, keys to species of all genera, and a species list. The work is heavily illustrated with specimen images, distribution maps, and habitat elevation charts.

Encyclopedia of biological invasions.

Island and Ocean Ecosystems, BRB

Rejmanek, Marcel

Simberloff, Dadniel

This encyclopedia illuminates a topic at the forefront of global ecology - biological invasions, or organisms that come to live in the wrong place. Written by leading scientists from around the world, the book addresses all aspects of this subject at a global level - including invasions by animals, plants, fungi, and bacteria - in succinct, alphabetically arranged articles. Scientifically uncompromising, yet clearly written and free of jargon, the volume encompasses fields of study including biology, demography, geography, ecology, evolution, sociology, and natural history and features many cross-references, suggestions for further reading, illustrations, an appendix of the world's worst 100 invasive species, a glossary, and more. The book features articles on well-known invasive species such the zebra mussel, chestnut blight, cheatgrass, gypsy moth, Nile perch, giant African snail, and Norway rat and details regions with especially large numbers of introduced species including the Great Lakes, Mediterranean Sea, Hawaiian Islands, Australia and New Zealand. This work will be of great value in ecology and conservation science. Invasive species are a severe and exponentially growing problem of the environment, and one difficult even to characterize, much less contain.-Edward O. Wilson, author and scientist "Second only to habitat loss mixed with climate disruption, invasive species represent the next most serious threat to biodiversity. The Encyclopedia of Biological Invasions, written by an impressive group of experts, now makes available to conservation biologists, managers, decision makers, and concerned citizens a comprehensive single source of this key topic."-Paul R. Ehrlich, co-author of The Dominant Animal

Patris, Sharon ... [et al.]

This document is part of a technical report series on conservation projects funded by the Critical Ecosystem Partnership Fund (CEPF) and the Conservation International Pacific Islands Program (CI-Pacific). The main purpose of this series is to disseminate project findings and successes to a broader audience of conservation professionals in the Pacific, along with interested members of the public and students. The reports are being prepared on an ad-hoc basis as projects are completed and written up. In most cases the reports are composed of two parts, the first part is a detailed technical report on the project which gives details on the methodology used, the results and any recommendations. The second part is a brief project completion report written for the donor and focused on conservation impacts and lessons learned. The CEPF fund in the Polynesia-Micronesia region was launched in September 2008 and will be active until 2013. It is being managed as a partnership between CI Pacific and CEPF. The purpose of the fund is to engage and build the capacity of non-governmental organizations to achieve terrestrial conservation. The total grant envelope is approximately US$6 million, and focuses on three main elements: the prevention, control and eradication of invasive species in key biodiversity areas (KBAs); strengthening the conservation status and management of a prioritized set of 60 KBAs and building the awareness and participation of local leaders and community members in the implementation of threatened species recovery plans.

Climate change impacts on migratory species: the path ahead

Climate Change Resilience, BRB

Available Online

UNEP/CMS/ZSL

The Zoological Society of London (ZSL) is conducting research for the UNEP Convention on Migratory Species (CMS) into the effects of climate change on species protected by CMS. Species have been identified as having a high, medium or low vulnerability to the threat of climate change and have been categorised on the basis of a standardised assessment process. This leaflet summarises the emerging results from an assessment of CMS Appendix I species, in order to provide guidance to policy makers at the earliest opportunity. Results highlight a number of processes by which greenhouse gas emissions and climatic changes will increasingly threaten migratory species; all species assessed will be affected by these impacts. A broad set of biological, geographical and socio-economic factors will influence species vulnerability. Identifying these factors and developing further conservation management practices will be essential for the short term future of these species. In the long term, the reduction of greenhouse gas emissions is vital if we are to avoid unmanageable levels of climate change.

Climate change and biodiversity in the European Union overseas entities

Petit, Jerome

Prudent, Guillaume

Climate change is a major threat to global biodiversity. From the tropics to the Poles, the worlds ecosystems are all under pressure. A study published in the scientific journal Nature posited that 15 to 37% of terrestrial animal and plant species could be at risk of extinction because of human-induced impacts on climate (Thomas et al., 2004). Scattered across the four corners of the Earth, European Union overseas entities, are home to a biological diversity that is as rich as it is vulnerable. Located in several global biodiversity hotspots, these territories are home to a far greater number of endemic animal and plant species than continental Europe. However, this natural wealth is under pressure from numerous quarters: habitat destruction, invasive alien species, pollution, over-exploitation of species; no territory has been spared. Today, climate change represents an additional threat to these ecosystems, and one which could possibly end up being as damaging as all the others combined.

Coping with climate change in the Pacific island region (CCCPIR): main report

Climate Change Resilience, Island and Ocean Ecosystems, BRB

SPC/GTZ

Within the context of an additional commitment of the German Federal Ministry for Economic Cooperation and Development (BMZ) for the ongoing ACCPIR Project GTZ commissioned an appraisal mission in order to investigate the options for extending it regionally and thematically. The regional scope of the mission includes all independent member states of the Secretariat of the Pacific Community (SPC). The thematic scope of the mission focused on climate change adaptation strategies for land- and marine based natural resources, adaptation options in the tourism sector and with regard to mitigation potentials to renewable energies as well as energy efficiency issues. Despite constraints in terms of time covering the whole South Pacific region, the regional institutional framework being under reconstruction and, the multitude of, hardly manageable donor initiatives in the field of climate change the team finally was confident that sufficient information was available to assess the climate change context of the region and to come up with a proposal which adds value to ongoing and planned climate change activities at the regional and national level.

Invasive species, climate change and ecosystem-based adaptation: addressing multiple drivers of global change

Climate Change Resilience, BRB

This report is targeted at policy-makers, particularly those responsible for developing climate mitigation and adaption strategies that address issues like conservation, ecosystem services, agriculture and sustainable livelihoods. It focuses on the primary linkages between invasive species and climate change, as well as the secondary and tertiary interactions of their corresponding impacts. Finally, the enclosed recommendations are intended to provide guidance on the best ways to integrate invasive species prevention and management into the consideration of climate change responses across a range of sectors. Building on a review of existing scientific and conservation literature (which is frequently centered on well-studied invasive species in developed countries), our research has reaffirmed that there are significant gaps and questions about the intersection of these two major drivers of change. The case studies included below highlight key relationships and questions related to invasive species, climate change and the role of ecosystem-based adaptation. The three key messages that can be distilled from this report are: 1. Climate change will have direct and second order impacts that facilitate the introduction, establishment and/or spread of invasive species. 2.Invasive species can increase the vulnerability of ecosystems to other climate-related stressors and also reduce their potential to sequester greenhouse gasses. 3.Using an ecosystem-based adaptation approach, these pressures on ecosystems and their ability to provide important services can be offset by preventing the introduction of new invasive species and by eradicating or controlling those damaging species already present.
