AquaMaps
AquaMaps is a collaborative project with the aim of producing computer-generated (and ultimately, expert reviewed) predicted global distribution maps for marine species on a 0.5 x 0.5 degree grid of the oceans based on data available through online species databases such as FishBase and SeaLifeBase and species occurrence records from OBIS or GBIF and using an environmental envelope model (see niche modelling) in conjunction with expert input. The underlying model represents a modified version of the relative environmental suitability (RES) model developed by Kristin Kaschner to generate global predictions of marine mammal occurrences. According to the AquaMaps website in August 2013, the project held standardized distribution maps for over 17,300 species of fishes, marine mammals and invertebrates. The project is also expanding to incorporate freshwater species, with more than 600 biodiversity maps for freshwater fishes of the Americas available as at November 2009. AquaMaps ...

C-squares
C-squares (acronym for the ''Concise Spatial QUery And REpresentation System'') is a system of spatially unique, location-based identifiers (geocodes) for areas on the surface of the earth, represented as cells from a latitude- and longitude-based Discrete Global Grid at a hierarchical set of resolution steps, obtained by progressively subdividing 10×10 degree World Meteorological Organization squares; the term "c-square" is also available for use to designate any component cell of the grid. Individual cell identifiers incorporate literal values of latitude and longitude in an interleaved notation (producing grid resolutions of 10, 1, 0.1 degrees, etc.), together with additional digits that support intermediate grid resolutions of 5, 0.5, 0.05 degrees, etc. The system was initially designed to represent data "footprints" or spatial extents in a more flexible manner than a standard minimum bounding rectangle, and to support "lightweight", text-based spatial querying; it can al ...

Environmental Niche Modelling
Species distribution modelling (SDM), also known as environmental (or ecological) niche modelling (ENM), habitat modelling, predictive habitat distribution modelling, and range mapping uses computer algorithms to predict the distribution of a species across geographic space and time using environmental data. The environmental data are most often climate data (e.g. temperature, precipitation), but can include other variables such as soil type, water depth, and land cover. SDMs are used in several research areas in conservation biology, ecology and evolution. These models can be used to understand how environmental conditions influence the occurrence or abundance of a species, and for predictive purposes (ecological forecasting). Predictions from an SDM may be of a species’ future distribution under climate change, a species’ past distribution in order to assess evolutionary relationships, or the potential future distribution of an invasive species. Predictions of current and/or f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Biodiversity Informatics
Biodiversity informatics is the application of informatics techniques to biodiversity information, such as taxonomy, biogeography or ecology. Modern computer techniques can yield new ways to view and analyze existing information, as well as predict future situations (see niche modelling). Biodiversity informatics is a term that was only coined around 1992 but with rapidly increasing data sets has become useful in numerous studies and applications, such as the construction of taxonomic databases or geographic information systems. Biodiversity informatics contrasts with "bioinformatics", which is often used synonymously with the computerized handling of data in the specialized area of molecular biology. Overview Biodiversity informatics (different but linked to bioinformatics) is the application of information technology methods to the problems of organizing, accessing, visualizing and analyzing primary biodiversity data. Primary biodiversity data is composed of names, observation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biogeography
Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time. Organisms and biological communities often vary in a regular fashion along geographic gradients of latitude, elevation, isolation and habitat area.Brown University, "Biogeography." Accessed February 24, 2014. . Phytogeography is the branch of biogeography that studies the distribution of plants. Zoogeography is the branch that studies distribution of animals. Mycogeography is the branch that studies distribution of fungi, such as mushrooms. Knowledge of spatial variation in the numbers and types of organisms is as vital to us today as it was to our early human ancestors, as we adapt to heterogeneous but geographically predictable environments. Biogeography is an integrative field of inquiry that unites concepts and information from ecology, evolutionary biology, taxonomy, geology, physical geography, palaeontology, and climatology.Dansereau, Pierre. 1957 ...

Sea Around Us Project
The Sea Around Us is an international research initiative and a member of the Global Fisheries Cluster at the University of British Columbia. The Sea Around Us assesses the impact of fisheries on the marine ecosystems of the world and offers mitigating solutions to a range of stakeholders. To achieve this, the Sea Around Us presents fisheries and fisheries-related data at spatial scales that have ecological and policy relevance, such as by Exclusive Economic Zones, High Seas areas, or Large Marine Ecosystems. All spatialized data are visualized either graphically or mapped, and all data can be downloaded. Global fisheries catches from 1950 to the present are available, under explicit consideration of coral reefs, seamounts, estuaries and other critical habitats of fish and marine invertebrates. The data presented, which are all freely available, are meant to support studies of global fisheries trends and the development of sustainable, ecosystem-based fisheries policies. In the ea ...

CSIRO Marine And Atmospheric Research
CSIRO Oceans and Atmosphere (O&A) is one of the current 8 Business Units (formerly: Flagships) of the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australia's largest government-supported science research agency. History The CSIRO Oceans and Atmosphere (O&A) Business Unit was formed in 2014 as one of the then 10 "Flagship" operational units of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) as part of a major organisational restructure; from 2015 onwards the term "Flagship" was officially dropped. This Business Unit was formed essentially as a synthesis of the pre-existing CSIRO Division of Marine and Atmospheric Research (CMAR), representing the scientific capability, and the previously established Wealth from Oceans (WfO) Flagship, which was the route via which much of the relevant Australian government research funding was directed. As at 2016, its Director is Dr. Ken Lee, previously WfO Flagship Director. The O&A Business Uni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Invertebrate
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50 μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra'', whi ...
