Multimodal SADs linked to spatial and taxonomic breadth
Species abundance distribution (SAD) models using OBIS and GBIF data reveals multimodality patterns are rather common and increase with ecological heterogeneity.
Some like it warm? Warm-dwelling species have increased in response to climate change in western/central Europe
A new study published in Nature Ecology & Evolution, using data from OBIS, showed effects of climate change on species’ abundances, with an increase of warm-dwelling marine fish in the North Sea.
Too hot at the Equator?
A recent review of the literature and available data on latitudinal gradients in marine species richness in OBIS found that in all previous studies, and for a dataset of 65 000 species, they were bimodal, with a dip in richness ...
Highest marine species richness is found in tropical coastal areas
Costello & Chaudhary (2017) used data from OBIS to show that marine species richness is higher in the coastal tropics and decreases with depth. The paper reviews what factors have led to species diversification, and how this knowledge informs conservation ...
Analysis of OBIS maps distinct biogeographic realms in the world ocean
Analysis of OBIS demonstrates for the first time that the ocean can be classified into distinct realms based on the uniqueness of their animals and plants. The findings have been published in the journal Nature Communications.
Plant feeding promotes diversity in the Crustacea
Poore et al. (2017) showed that the ability to eat seaweeds and plants promotes diversity among crustaceans, just as it does among herbivorous insects. The records from OBIS for each clade were analysed to estimate range size, latitudinal range and ...
Illuminating the Twilight Zone - expert panel maps the world's mesopelagic zone
A new study using data from OBIS identified 33 mesopelagic ecoregions of the world’s oceans. This is a first step towards a dynamic mesopelagic biogeography, which forms an important baseline to assess human impacts on the mesopelagic, or "twilight" zone; ...
Identifying relevant predictors for marine species distribution modelling with MarineSPEED
Bosch et al. (2017) showed that while temperature is a relevant predictor of global marine species distributions, considerable variation in predictor relevance is linked to the species distribution modelling (SDM) set-up. A standardized benchmark dataset (MarineSPEED) was created by combining ...
Counting seals with drones and thermal imagery
Alexander Seymour and his team at the Duke University Marine Laboratory, and Fisheries and Oceans Canada counted 3,355 grey seals using unoccupied aerial vehicles (UAV) with thermal sensors. The case study was published in Nature’s Scientific Reports journal. The data ...
