Filtering efficiency and feeding mechanisms of Daphnia pulex on Microcystis aeruginosa and Nannochloropsis [PDF]
The filtering and feeding rate of Daphnia pulex from the Old Durham Reservoir, Durham, NH, were measured to determine the feeding efficiency on different concentrations of non-toxic Nannochloropsis (Class Eustigmatophyceae) and toxigenic cyanobacteria ...

Sexual cannibalism (SC), where one mating partner consumes the other in the context of mating, is especially prevalent among spiders. However, the evolution of SC in spiders is still not fully understood. We review key hypotheses for SC and explore how female‐initiated SC has driven the evolution of various male counter‐adaptations to mitigate its ...

Extreme Silk Toughness in Caerostris Spiders Is Limited to Adult Females
We ask whether species with exceptionally tough silk, like Caerostris bark spiders, show different developmental patterns in silk toughness between ontogenetic stages and sexes. We found that only large females produce exceptionally tough silk with higher initial stiffness, while juvenile females as well as adult and juvenile males produce inferior ...

Abstract Ecologists and evolutionary biologists are increasingly turning to 3D models to use in scientific research. Natural history museums are one of the primary sources for specimens used as 3D models, and efforts are underway to digitize their collections using methods like photogrammetry.

Abstract Microplastic input into the ocean represents an increasing threat to marine biota and may endanger the functioning of marine ecosystems, especially in semi‐enclosed basins, such as the Mediterranean Sea. The size spectrum of microplastics overlaps with that of nano‐microplankton (2–200 μm), thus potentially misleading suspension‐feeding ...

Recognition and utilization of egg maculation signals by two sympatric host species
Egg color polymorphism and egg mimicry are important adaptations in the game process between hosts and brood parasites at the egg stage. The ability of hosts to recognize and reject parasitic eggs based on effective egg characteristics is a crucial ...

Survival Remains High in Griffon Vultures 40 Years After Reintroduction
The reintroduction of the Griffon vulture (Gyps fulvus) in French Grands Causses in 1981 is largely regarded as a significant translocation success. 40 years of quality data from intensive monitoring allows us to investigate the survival rates in this long‐lived population on the long term, but also to reflect on the crucial role of adaptive management
