Several clades of spiders whose females evolved giant sizes are known for extreme sexual behaviors such as sexual cannibalism, opportunistic mating, mate-binding, genital mutilation, plugging and emasculation. However, these behaviors have only been tested in a handful of size dimorphic spiders. Here,...
Sexual selection was first proposed by Charles Darwin and can be considered a “special case” of natural selection, by which fitness and reproductive success of an individual is primarily determined by its ability to choose ...
From Lavoisier’s perspective, for example, the antiquated term dephlogisticated air sometimes means “what remains when phlogiston is removed from the air” (in which case, because there is no such substance as phlogiston, the term fails to pick out anything in the world). But at other ...
Spiders are mega diverse arthropods and play an important role in the ecosystem. Identification of this group is challenging due to their cryptic behavior, sexual dimorphism, and unavailability of taxonomic keys for juveniles. To overcome these obstacles, DNA barcoding plays a pivotal role in spider...
No, "super-Earth" is not Captain Planet's dorky cousin. In astronomy, the term refers to a type of planet with a mass up to 10 times greater than Earth's. Star surveys have turned up oodles of these worlds that could have the right conditions for liquid water. This means alien life...
With the Open Science approach becoming important for research, the evolution towards open scientific-paper reviews is making an impact on the scientific community. However, there is a lack of publicly available resources for conducting research activities related to this subject, as only a limited ...
Prospects for using DNA barcoding to identify spiders in species-rich genera E. A Robinson, G. Blagoev, P. D.N Hebert, et al. ZooKeys, 16 (2009) Polyphyly of the hawk genera leucopternis and Buteogallus(Aves, accipitridae): multiple habitat shifts during the neotropical buteonine diversific...
The first analysis of extreme calving events in Antarctica finds no correlation with climate change, highlighting the significance of common, smaller calving events for ice loss and instability. Antarctica 10 amazing things we found on Mars in 2024, from hundreds of 'spiders' to a 'Martian dog...
Using similar arguments, the dramatic evidence of the sensory processing, analytical and prediction ability of salticid spiders provides evidence for awareness greater than in any other invertebrates except cephalopods but we have little evidence of a pain system so do not at pres...
after a 50 y long-term field experiment established at Martonvásár, Hungary. Four types of crop rotation were chosen for sampling: corn monocropping, corn-alfalfa, corn-wheat, and corn-spring barley-peas-wheat. Community composition of AMF in soil was analyzed with a molecular approach amplify...
