In two harvester ant populations, queens and workers from the same colonies are genetically very different, with only queens coming from pure species-specific lineages. The ants have committed to a hybrid workforce strategy, relying on interspecific hybrid workers for survival.
The SimBioS Center will enable biologists to integrate, analyze, and model data on human health and disease using innovative software programs. The center aims to bring high-quality physical modeling capabilities to all biologists, addressing key challenges in simulating living systems from individual atoms to entire organisms.
A minor earthquake occurred in the Evansville area with a preliminary magnitude of 3.9, according to the USGS. This region has been identified as having a potential for damaging earthquakes.
USGS researchers link Mercury levels in Lake Tulane to global climate changes, while also analyzing African dust's role in affecting coral health. Additionally, scientists explore the Chesapeake Bay bolide's crater formation and its structural implications.
Scientists from various disciplines gather to develop recommendations for restoring Pacific rivers for salmon habitats. The workshop aims to select candidate watersheds and measurements for evaluating restoration success, bringing together expertise in watershed restoration.
A new study from the USGS and Oregon Graduate Institute reveals that up to 9,000 community water wells in 31 states may be contaminated with MTBE due to proximity to leaking underground storage tanks. The EPA has announced plans to phase out MTBE use in gasoline, but it will persist in the environment for at least a decade.
The USGS is launching a citizen science program to monitor frogs and toads across the United States. Volunteers will collect data on local amphibian populations, helping scientists understand the decline of these species worldwide.
The BioOne Board will guide policies and progress, comprising ten individuals from collaborating organizations. The aggregation will offer cross-journal searches and inter-journal linking, with a broad selection of journals from AIBS member societies.
The USGS has been monitoring a series of large earthquakes around the world since August 17. The seismic activity is believed to be related to stress buildup in the Earth's crust. Scientists will discuss their findings and lessons learned from recent earthquakes, including those in Turkey, Greece, Taiwan, and Mexico.
The USGS has successfully released captive-reared puaiohi birds into the wild, with four chicks having already fledged. This is a significant step towards the species' recovery, with biologists optimistic about re-establishing a self-sustaining population.
The USGS report synthesizes current information to document the changing nation's biological resources, identifying key factors affecting biological resources nationwide. Land use, water use, and nonindigenous species are the primary factors having broad-scale effects.
UC and CREW biologists use a basic hole-puncher to collect plant samples, then study how to protect them from dehydration and rehydration. They discover that plants secrete a hormone called abscisic acid to protect themselves during dry times.
Taxonomic names are in flux, reflecting current knowledge about species. The USGS-developed ITIS database provides a tool to link and integrate name changes over time.
The USGS has taken the lead in establishing the National Biological Information Infrastructure (NBII) to increase access to biological diversity data and information. The initiative aims to democratize environmental science by providing a broad array of knowledge on the diversity of nature's living creatures.
At the AAAS meeting in February 1998, USGS scientists presented research on predicting the fate of contaminants in the New York Bight and developing a regional map of sea floor characteristics. The study aims to provide information for guiding habitat and resource management and monitoring long-term environmental change.
The ITIS system provides a unified way of naming nature's living organisms, enabling easy access to credible databases and information on species origin and distribution. This standardized terminology facilitates accurate documentation, data sharing, and research among scientists, resource managers, and the general public.
USGS geochemist Keith Kvenvolden's study suggests that most oil residues in Monterey Bay are likely from natural seeps, rather than ruptured tankers. The study found unusually heavy carbon isotopic compositions characteristic of crude oils from the Miocene Monterey Formation of California.
Researchers successfully cloned the first mammalian clock gene, identified as 'Clock', which regulates biological clocks and sleep patterns. The discovery provides new insights into the genetic basis of individual differences in human sleep-wake behavior and may lead to the development of new drugs to regulate circadian rhythms.
The U.S. Geological Survey's 1998 budget allocates $6.5 million more to address pressing demands on natural resources and mitigate hazards. The funding boost enhances biological science research, expands earthquake monitoring, and improves drinking water quality information.
The review paper reviews powerful computational tools in studying ecology, genetics and evolution, infectious diseases and immunology. Computational biologists use models to understand the behavior of entire systems, mediated by smaller and larger scales.
