    Pelagic fish predation is stronger at temperate latitudes than near the equator

    Data and filtering We quantified the relative predation that is exerted by large pelagic fish predators based on four publicly available datasets from pelagic longline fishing (West Pacific, East Pacific, Atlantic, and Indian Ocean), each managed by an independent commission (see Supplementary Table 1 for details). All datasets included catch per effort records per month and […] More

    Diurnal activity in cane toads (Rhinella marina) is geographically widespread

    Standardised surveys in australia We quantified the abundance of cane toads by day and by night at sites along two continent-scale transects, each covering the full 84-year timespan of the toad invasion chronosequence in Australia (Table 1). The “east coast transect” (surveyed October 2017 to April 2018) consists of 16 sites running north-south, beginning near Townsville […] More

    Conspecific and heterospecific pheromones stimulate dispersal of entomopathogenic nematodes during quiescence

    Rearing EPNs S. carpocapsae (All strain) and S. feltiae (SN strain) IJs (ARBICO Organics, Tucson, AZ), S. scapterisci, S. riobrave (355), S. glaseri (11a&7b strain), S. diaprepesi, H. bacteriophora (HP88 strain), H. indica (HOM1 strain) and H. floridensis (K22 strain) have been kept in culture using Galleria mellonella in the laboratory. To maintain cultures, commercially […] More

    Bats seek cold roosts

    For hibernating mammals, increases in yearly temperature can impact hibernation quality, leading to subsequent fitness fallouts. For bats, hibernating at warmer temperatures requires increased energy expenditure, which can result in lowered survival or reproductive success. While previous studies have indicated that warming may promote range changes for some bat species, the impact on cryophilic (cold […] More

    Stranded investments

    J. Environ. Econ. Manag. 100, 102277 (2020). Financial investments in fossil fuel assets could be lost if climate policies limit emissions in line with climate targets. Stranded assets, as these are known, thus represent an investment risk which may not be currently accounted for by investors and company valuations. The German climate policy Klimabeitrag — […] More

    Heterospecific eavesdropping on an anti-parasitic referential alarm call

    Sites and study species Both playback experiments (described below) took place in multiple wetlands in Champaign (n = 3), Iroquois (n = 1), and Vermilion counties (n = 3) in central Illinois, USA. Sites were comprised of mesic shrubland habitat, with dominant shrubs including willow (Salix spp.), dogwood (Cornus spp.), and Autumn Olive (Elaeagnus umbellate), with mesic grasses abundant among shrubs. Patches […] More

    Small phytoplankton dominate western North Atlantic biomass

    Mean dynamic topography (MDT) delineates phytoplankton regional variation MDT divides the North Atlantic into four regions: subpolar, temperate, subtropical, and Gulf Stream/Sargasso Sea (Fig. 1a) (ref. [23]). Two meridional transects covered these four subregions capturing the initiation of winter deep mixing and the peak of the bloom following the water column re-stratification (Fig. S1). Fig. 1: […] More
