The ability of planktonic copepods to detect and pursue remote prey is well documented, but there are no empirical descriptions of their three-dimensional (3D) sensory fields. In this study, the attack volume of females of Euchaeta rimana Bradford, a planktonic calanoid copepod, was mapped by plotting the positions of attacked prey within a standardized 3D coordinate system defined by the body ...

One million to two million years ago, most of today's large, predatory mammals coexisted with larger extinct species, such as saber-toothed cats and giant running bears. Comparisons of tooth fracture frequencies from modern and Pleistocene carnivores imply that predator-prey dynamics and interspecific interactions must have been substantially different 36,000 to 10,000 years ago. Tooth fracture...

This article introduces predatory publishers in the context of biomedical sciences research. It describes the characteristics of predatory publishers, including spamming and using fake metrics, and it describes the problems they cause for science and universities. Predatory journals often fail to properly manage peer review, allowing pseudo-science to be published dressed up as authentic scienc...

This article is a first-hand account of the author's work identifying and listing predatory publishers from 2012 to 2017. Predatory publishers use the gold (author pays) open access model and aim to generate as much revenue as possible, often foregoing a proper peer review. The paper details how predatory publishers came to exist and shows how they were largely enabled and condoned by the open-...

A new species of the predatory mite family Caeculidae, N. orientalis sp. nov., is described and illustrated, based on adult and all active immature instars from moss and forest litter of various localities in Thailand. Neocaeculus orientalis sp. nov. differs from its congeners in uniquely having the adult femur I divided but femora II-IV entire, adult coxal setation of 5-1-2-1 (4a excluded), an...

A spokesperson for the Interior Department announced today the American Scientist was being placed on the endangered species list. Under the Endangered Species Act, an animal is placed on the list when numbers drop below a level critical for the continued vitality of the species. The spokesperson said the decision was forced by the continuation of predatory behavior by university administrators...

the modeling investigation in this paper discusses the system level effects of a toxicant on a three species food chain system. in the models, we have assumed that the presence of top predator reduces the predatory ability of the intermediate predator. the stability analysis of the models is carried out and the sufficient conditions for the existence and extinction of the populations under the ...

Mimicry complexes typically consist of multiple species that deter predators using similar anti-predatory signals. Mimics in these complexes are assumed to vary in their level of defence from highly defended through to moderately defended, or not defended at all. Here, we report a new multi-order mimicry complex that includes at least 140 different putative mimics from four arthropod orders inc...
