Knowledge of mammalian diversity is still surprisingly disparate, both regionally and taxonomically. Here, we present a comprehensive assessment of the conservation status and distribution of the world's mammals. Data, compiled by 1700+ experts, cover all 5487 species, including marine mammals. Global macroecological patterns are very different for land and(More)
We used a model of the pelagic ecosystem in the eastern tropical Pacific Ocean to explore how climate variation at El Niño – Southern Oscillation (ENSO) scales might affect animals at middle and upper trophic levels. We developed two physical-forcing scenarios: (1) physical effects on phytoplankton biomass and (2) simultaneous physical effects on(More)
An ecosystem approach to fisheries management is a widely recognized goal, but describing and measuring the effects of a fishery on an ecosystem is difficult. Ecological information on the entire catch (all animals removed, whether retained or discarded) of both species targeted by the fishery and nontarget species (i.e., bycatch) is required. We used data(More)
A motion detection framework is presented that integrates spatial and temporal data by decomposition of the feature space. Temporal data is employed to monitor frame changes on a per-pixel basis, whilst the spatial data is used to provide region-based segmentation of image frames. The thresholded difference image from the change detection is then fused with(More)
Shore based surveys of northbound gray whale calves were conducted between March and June from for the 10 consecutive surveys. Over this period, annual estimates averaged 4.1% of the total abundance as estimated by Laake et al. (2009). The estimates from 2001-2010 represent the most recent of a 17-year time series of surveys from this site and include both(More)
— A change detection framework which fuses both spatial and temporal data using fuzzy if-then rules is presented. Temporal data is used on a per-pixel basis to monitor the sequence for changes by employing a fuzzy codebook model. Spatial data is gathered using a fuzzy multithresholding algorithm that decomposes the RGB color space into three color pair(More)
