This study evaluated the memory and visual discrimination capabilities of Enteroctopus dofleini, the Giant Pacific Octopus. Octopuses have been known to have advance sensory capabilities and through this study we challenged our specimen to remember and actively choose a specific patterned jar based on a visual pattern and positive reinforcement....
The "global marketplace" has been a driving force for change, resulting in a
dramatic increase in competition and expectations of consumers. With more mailing
options available, consumers are scrutinizing service and cost performance at a level
never-before experienced by the United States Postal Service. For an organization that
has operated...
The lionfish (Pterois volitans) is a successful invasive predator with large impacts on native fish populations in the western Atlantic. Lionfish predation may affect competition between prey species so it is important to understand whether lionfish display preferences between prey species. I investigated lionfish and native graysby grouper prey preference...
The purpose of this study was to investigate the effectiveness of a guidance-based career exploratory program related to skilled trades and technical occupations for internal-external locus of control middle school females in Murray, Kentucky. The problem was to determine the change in career interests resulting from the interaction between a...
Zonal and meridional Seasoar sections centered at 1°50’S, 156°06’E were repeated >30 times in three 20-day periods between November 13, 1992, and February 15, 1993. Both sections were 130 km long, and sampling depth was 0–280 m, with a vertical resolution of ~2 dbar (2 x 104 Pa) and a...
Interest is expanding for the potential role of estuaries, particularly seagrass and salt marsh habitats, to sequester carbon, mitigate ocean acidification, and support abundant fisheries. The important functions of estuaries are part of a broader set of ecosystem services, or benefits to humans, which are regulated by ocean and watershed...
Coastal and marine ecosystems in Latin America and the Caribbean are undergoing a rapid and drastic transformation. Dense human populations are concentrated in coastal areas, leading to increased coastal development, destruction of near-shore habitats, pollution, and overexploitation of marine resources. For most Latin American and Caribbean countries, the deterioration of...
An international Coupled Ocean-Atmosphere Response Experiment
(COARE) was conducted in the warm-pool region of the western equatorial
Pacific Ocean over a four-month period from November 1992 through
February 1993 (Webster and Lukas, 1992). Most of the oceanographic and
meteorological observations were concentrated in the Intensive Flux Array
(IFA) centered at...
Eelgrass (Zostera marina) provides critical ecosystem functions and services and is a vital biogenic habitat on Washington’s marine aquatic reserves but its placement at the land-sea interface leaves it vulnerable to multiple environmental and anthropogenic stressors. In this study, published scientific literature is examined to identify thresholds of environmental stressors...
Ecologists must increasingly balance the need for accurate predictions about how ecosystems will be affected by climate change, against the fact that making such predictions at the ecosystem-level may be infeasible. Although information about responses of individual species to a changing environment is increasing, scaling such information to the community...
