Research
Ecoregions of the United States--USFS
http://www.fs.fed.us/land/ecosysmgmt/ecoreg1_home.html
Ecological Subregions of the United States--USFS
http://www.fs.fed.us/land/pubs/ecoregions/
The electronic (interactive) version of a 1994 publication by the US Forest Service (USFS), these companion sites are based on the National Hierarchical Framework of Ecological Units, designed to provide "a standardized method for classifying, mapping, and describing ecological units" in the US. The first site, "Ecoregions of the United States," contains three simple color maps of the United States (including Alaska, Hawaii and Puerto Rico) showing generalized ecological boundaries. At the coarsest spatial scale, the Ecosystem Domains map delineates Dry, Humid Temperate, and Humid Tropical Domains. At the intermediate scale, an Ecosystem Divisions map delineates more than a dozen ecosystem types, ranging from tundra to rainforest. At the finest scale, over 50 Ecosystem Provinces are delineated. By clicking on a color type for any map (i.e., an ecosystem type), users may access further information on the abiotic and biotic characteristics within that ecosystem. A companion site, Ecological Subregions of the United States, contains the biophysical descriptions for the color-coded maps. This is a solid resource for anyone seeking broad ecosystem classifications for the United States. [LXP]

Animal Omnibus
http://www.birminghamzoo.com/ao/
Designed with children in mind, the Birmingham Zoo's Animal Omnibus site is "a list of web sources indexed by the name of the animal." Users search by animal name to get returns in the form of hyperlinked resource lists. The resource lists contain sites ranging from simple color photographs of individual species to sites steeped in scientific classification to publicly targeted zoo sites. Animal Omnibus may also be browsed by generic name within each taxonomic category (amphibians, arthropods, birds, dinosaurs, fish, mammals, mollusks, and reptiles). Although depth of content varies widely, this unique and diverse collection of information types is at once unpredictable and refreshing. [LXP]

SHEBA: Surface Heat Budget of the Arctic Ocean
http://sheba.apl.washington.edu/
The Ice Station SHEBA (Surface Heat Budget of the Arctic Ocean) has just completed one year of being frozen into the Arctic ice, while gathering information to improve climate modeling. When sea ice is formed there are important changes in polar and global climate processes. Scientists from the US, Russia, Norway, and Canada are collaborating on the SHEBA project, a 5-year National Science Foundation research project. Although not all sections of the site are current, the SHEBA homepage offers background information, data, and updates of research on the Ice Station SHEBA, as well as links to other ice- or climate-related sites.

New Data
Catalogue of the Type Specimens of the Dutch Herbaria
http://nhncml.leidenuniv.nl/types/
Now online is the first update of a computerized catalogue of 40,000 botanical Type Specimens, an impressive resource from the four largest herbaria in the Netherlands (Amsterdam, Leiden, Utrecht and Wageningen). The catalogue database is searchable by taxonomic level (family, genus, species), author, collector, year, country, locality, or vernacular. Search returns apply specifically to each specimen and vary accordingly, but descriptive fields include: field notes, vegetation, and economic use, in addition to location, collector, specimen number, and herbarium address. Complementing the incredible amount of information presented in this catalogue, 70% of all type specimens are accompanied by a digital image of the specimen. Though not for the beginning student, this database may be a gold mine for taxonomic botanists and educators. [LXP]

9. Lesser Snow Geese and the Trophic Cascade
http://research.amnh.org/~rfr/hbp/kenintro.html
This week's In The News addresses recent findings (published in the October 16, 1998 issue of Science) that killer whale predation on sea otters in the North Pacific has "created an ecological chain reaction in nearshore ecosystems." Such ecological chain reactions refer to the disruption of the complex balance between predator and prey species. Killer whales, which traditionally fed on the (now scarce) Steller sea lions and harbor seals, have recently shifted their diet to sea otters. The resulting decline in sea otters has, in turn, led to an increase in sea urchins (sea otter prey), which in turn have deforested many kelp (seaweed) beds in the nearshore marine community. Although killer whales are playing a critical role in the current disruption, this chain of interactions "was probably initiated by anthropogenic changes in the offshore oceanic ecosystem" -- namely, the region's burgeoning fisheries, higher ocean temperatures, and the depletion of baleen whales. Similar "trophic cascades" have been well documented for lakes and in other systems (e.g. Snow Geese in the Arctic), but this research provides a new example of a disrupted food web that may reach a wider audience -- as it involves several highly charismatic vertebrates. The nine resources above describe the recent scientific findings, provide background information on food webs, and offer several resources for understanding ecological (trophic) chain reactions.

The first two resources, from University of California Santa Cruz (1) and the daily news source UniSci (2), describe how killer whale predation on sea otters is disrupting coastal ecosystems in the North Pacific. Declining numbers of sea otters (3) and of Steller sea lions (4) are discussed in these two articles from the Environmental News Network. For background information on food webs, this course page (5) from Okanagan University College, British Colombia (Canada), offers a formal explanation of food webs; a more informal (but photo-illustrated and interactive) description is provided for the K-12 level by the Lloyd Center (6). overfishing by humans is one of the suggested causes behind the shift in killer whale feeding (from seals to otters). This webpage, from naturalSCIENCE, summarizes a recent important article on the far-reaching impacts of overfishing (7). At this site, a recent scientific article (8) from cutting-edge ecosystem scientists Drs. Carl Walters and Daniel Pauly describes EcoSpace, "an exploratory tool for analysis of trophic and spatial relationships." The EcoSpace model may be used, in part, to evaluate the ecosystem consequences of overfishing (see the February 18, 1988 Scout Report for Science & Engineering). (9) An example of a non-oceanic trophic cascade is provided by the American Museum of Natural History in this annotated slide-show on Lesser Snow Geese. [LXP]
