Copula lucentia sp. nov., a new box jellyfish (Cnidaria: Cubozoa: Carybdeida) from Western Mediterranean SeaNARA Subscribed
A new species of box jellyfish, Copula lucentia sp. nov., is described from El Campello, Spain, and compared to the holotype of Copula sivickisi that was successfully recovered after being lost for almost 60 years. So far, the only cubozoan species recorded in the Western Mediterranean was Carybdea marsupialis . The genus Copula just included the type species ( Copula sivickisi ) reported from different localities in the Pacif...
Generating biomass-at-age indices for fisheries stock assessments with acoustic data collected by uncrewed surface vessels (USVs) has been hampered by the need to resolve acoustic backscatter with contemporaneous biological (e.g., age) composition data. To address this limitation, Pacific hake ( Merluccius productus ; “hake”) acoustic data were gathered from a USV survey (in 2019) and acoustic-trawl survey (ATS; 2019 and eight...
Vulnerability to climate change of managed stocks in the California Current large marine ecosystemOA Marine
Introduction Understanding how abundance, productivity and distribution of individual species may respond to climate change is a critical first step towards anticipating alterations in marine ecosystem structure and function, as well as developing strategies to adapt to the full range of potential changes. Methods This study applies the NOAA (National Oceanic and Atmospheric Administration) Fisheries Climate Vulnerability Asse...
Heat wave occurrences over Senegal during spring: Regionalization and synoptic patternsNARA Subscribed
Based on 12 Senegalese stations of the Global Summary of the Day (GSOD) database (1979–2014), heat waves (HW) are defined for each station in spring (March–April–May, the hottest season in Senegal) as the daily maximum temperature (Tx), minimum temperature (Tn), or average apparent temperature of the day (AT), exceeding the corresponding 95% mobile percentile for at least three consecutive days. A hierarchical cluster analysis...
Protoxenidae fam. nov. (Insecta, Strepsiptera) from Baltic amber — a ‘missing link’ in strepsipteran phylogenyNARA Subscribed
A male specimen of a new strepsipteran genus and species ( Protoxenos janzeni gen. et sp. nov.) and family (Protoxenidae fam. nov.) found in Baltic amber is described and illustrated. It shows features which are apparently more plesiomorphic than in hitherto known strepsipterans, such as laterally inserted eight‐segmented antennae, very robust mandibles with a broad base, a prominent galea, a comparatively short, transverse me...

Amazonian Tree Mortality during the 1997 El Niño DroughtNARA Subscribed
In 1997, the Amazon Basin experienced an exceptionally severe El Niño drought. We assessed effects of this rare event on mortality rates of trees in intact rain forest based on data from permanent plots. Long‐term (5‐ to 13‐year) mortality rates averaged only 1.12% per year prior to the drought. During the drought year, annual mortality jumped to 1.91% but abruptly fell back to 1.23% in the year following El Niño. Trees dying...
