Data from: Sex determination in the wild: a field application of loop-mediated isothermal amplification successfully determines sex across three raptor speciesAlejandro Centeno-Cuadros, Ibrahim Abbasi & Ran Nathan
PCR-based methods are the most common technique for sex determination of birds. Although these methods are fast, easy and accurate, they still require special facilities that preclude their application outdoors. Consequently, there is a time lag between sampling and obtaining results that impedes researchers to take decisions in situ and in real time considering individuals’ sex. We present an outdoor technique for sex determination of birds based on the amplification of the duplicated sex-chromosome-specific gene...
Data from: Mass seasonal bioflows of high-flying insect migrantsGao Hu, Ka S. Lim, Nir Horvitz, Suzanne J. Clark, Don R. Reynolds, Nir Sapir & Jason W. Chapman
Migrating animals have an impact on ecosystems directly via influxes of predators, prey, and competitors and indirectly by vectoring nutrients, energy, and pathogens. Although linkages between vertebrate movements and ecosystem processes have been established, the effects of mass insect “bioflows” have not been described. We quantified biomass flux over the southern United Kingdom for high-flying (>150 meters) insects and show that ~3.5 trillion insects (3200 tons of biomass) migrate above the region annually. These flows...
Data from: Various competitive interactions explain niche separation in crop-dwelling web spidersItai Opatovsky, Efrat Gavish-Regev, Phyllis G. Weintraub & Yael Lubin
Competition for resources is a major organizing principle in communities of organisms that share similar ecological niches. Niche separation by means of exploitation or interference competition was investigated in two taxa of crop-inhabiting spiders that overlap in microhabitat use and have similar web design. Competition for prey and web sites was tested in microcosm experiments with the most common species that build sheet-webs: Enoplognatha gemina (Theridiidae) and Alioranus pastoralis (Linyphiidae). A field survey over the...
Data from: A theoretical foundation for multi-scale regular vegetation patternsCorina E. Tarnita, Juan A. Bonachela, Efrat Sheffer, Jennifer A. Guyton, Tyler C. Coverdale, Ryan A. Long & Robert M. Pringle
Self-organized regular vegetation patterns are widespread1 and thought to mediate ecosystem functions such as productivity and robustness, but the mechanisms underlying their origin and maintenance remain disputed. Particularly controversial are landscapes of overdispersed (evenly spaced) elements, such as North American Mima mounds, Brazilian murundus, South African heuweltjies, and, famously, Namibian fairy circles. Two competing hypotheses are currently debated. On the one hand, models of scale-dependent feedbacks, whereby plants facilitate neighbours while competing with distant individuals,...
Data from: The representation of prediction error in auditory cortexJonathan Rubin, Nachum Ulanovsky, Israel Nelken & Naftali Tishby
To survive, organisms must extract information from the past that is relevant for their future. How this process is expressed at the neural level remains unclear. We address this problem by developing a novel approach from first principles. We show here how to generate low-complexity representations of the past that produce optimal predictions of future events. We then illustrate this framework by studying the coding of ‘oddball’ sequences in auditory cortex. We find that for...
