HEAR CLOSING      HEAR CLOSING      HEAR CLOSING

A message from Dr. David Duffy, Pacific Cooperative Studies Unit (PCSU), University of Hawaii (posted 05 November 2012):

Because of a lack of funds, HEAR (www.hear.org) may close as soon as December 15, although there may be enough funds to extend it until February 15. This will mean several things. The web site will be placed on a new server although it is not clear who will pay for the server or for transitioning the site. HEAR data will not be updated. The Pacific Ecosystems at Risk (PIER) (http://www.hear.org/pier/abtproj.htm) site will also become frozen, as will numerous books, reports and papers (http://www.hear.org/). As software evolves we will likely lose the ability to access the data. The various list servers will need new owners, otherwise moderated lists will cease to function altogether, while other lists will not be able to add or delete members. The photo collection (http://www.hear.org/starr/images/?o=plants) will remain accessible, but only through a third party site that will charge for access.

I should point out that we have already lost the original homes of both the Pacific Basin Information Node (PBIN) and Pacific Ecosystems at Risk (PIER) although they have found temporary refuges. Together with HEAR, they represent the corporate memory both here in Hawaii and across the Pacific of efforts to sustain our natural ecosystems and agriculture against problems caused by species alien to the islands. HEAR also serves as the glue that holds the community together, providing information and facilitating communication. I just hope hindsight is kind to this decision.

Taxonomy & nomenclature

Brachymyrmex obscurior information from ITIS
The Integrated Taxonomic Information System ITIS provides authoritative taxonomic information on Brachymyrmex obscurior, as well as other plants, animals, fungi, and microbes of North America and the world.

Images of 20 of the ant species of Hawaii help to identify the species.

Brachymyrmex obscurior images and description from Mississippi Entomological Museum
Brachymyrmex obscurior is compared to the similar B. patagonicus Mayr on this site, which includes high quality images of winged ants.


Impacts

Interspecific competition and coexistence between ants and land hermit crabs on small Bahamian islands (abstract)
Brachymyrmex obscurior Forel, drove off hermit crabs from food sources by recruiting large numbers of workers (Acta Oecologica, 2002).


Prevention

Change in Quarantine Action Policy for Ants Intercepted from Commodities Destined to the State of Hawaii
A policy change regarding quarantine action for ants intercepted from commodities in Hawaii is detailed here. The revised policy went into effect 10 April 2002.


Images

Images of Brachymyrmex obscurior (Formicidae) (brachymymex ant are provided by from Forest and Kim Starr.

Brachymyrmex obscurioir information from Antweb
Information about the ant Brachymyrmex obscurioir--including images of specimens--is available online from Antweb (California Academy of Science).


Distribution

Ants of Bermuda
The specimen records of 20 ant species of Bermuda are reviewed (Florida Entomologist, 2004).

Brachymyrmex obscurior most ubiquitous ant in Bahamian cays View info about Adobe Acrobat PDF format
If a small cay has only one ant species, it will almost always be Brachymyrmex obscurior. The open water distances separating the cays from each other from larger islands do not appear to be a major barrier to colonization.

A review of Bahamian ant (Hymenoptera: Formicidae) biogeography (Journal of Biogeography, 1998) View info about Adobe Acrobat PDF format
Results of surveys of native and exotic ants in the Bahamas are presented, and historical and ecological factors affecting the distribution of ant species are discussed.

Brachymyrmex obscurior among stowaways to Virgin Islands View info about Adobe Acrobat PDF format
Brachymyrmex obscurior was among several plant pests inadvertently transported to the British Virgin Isles in a shipment of potted plants from Florida, indicating the need for more effective measures to prevent continued spread of non-indigenous invertebrates to islands.


Discussion forums

Pacific Ant Group e-mail list (PAG-L@HAWAII.EDU)
The Pacific Ant Group discussion forum facilitates communication toward preventing establishment of Red Imported fire ant and other invasive ants on Pacific islands.

The Hawaiian Ecosystems at Risk project (HEAR) is currently funded by grants from the Hau'oli Mau Loa Foundation and the U.S. Forest Service with support from PCSU (UH Manoa). Historically, HEAR has also received funding and/or support from the Pacific Basin Information Node (PBIN) of the National Biological Information Infrastructure (NBII), PIERC (USGS), the USFWS, HCSU (UH Hilo), and HALE (NPS).
