Unravelling Evolutionary Dynamics of Female Sexual Cannibalism and Male Reproductive Strategies in Spiders

open access: yesIntegrative Zoology, EarlyView.
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 ...

To seal a wound, caterpillars transform blood from a viscous to a viscoelastic fluid in a few seconds

open access: yesFrontiers in Soft Matter
In insects vulnerable to dehydration, the mechanistic reaction of blood after wounding is rapid. It allows insects to minimize blood loss by sealing the wound and forming primary clots that provide scaffolding for the formation of new tissue.

The Effects of Noise on the Juvenile Life Stage of Crustaceans: Behavioral, Cellular, and Molecular Responses in Procambarus clarkii

open access: yesIntegrative Zoology, EarlyView.
Juvenile Procambarus clarkii exposed to noise exhibited behavioral changes, shifts in enzymatic activity, and altered expression of stress and immune genes. The findings highlight the sensitivity of invertebrate juveniles to anthropogenic acoustic pollution.

Hemolymph composition, gene expressions in the gills, and thus the survival of euryhaline crabs are controlled by ambient minor cations according to osmotic condition‐dependent manner

open access: yesEcology and Evolution, 2020
Na+ and Cl− are the most abundant dissolved ions in seawater, constituting ~ 85% of total ions. They significantly affect the osmolality of body fluids of marine invertebrates.

Histomorphology Structure of the Gastric Caecum, Midgut, and Malpighian Tubules in Adult Flatheaded Pine Borer Chalcophora mariana (Linnaeus, 1758) (Coleoptera: Buprestidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT The pine weevil is one of the largest species in the jewel beetle (Buprestidae) family found in Central Europe and Turkey. Chalcophora mariana is generally considered a secondary guest and primarily develops in weakened, decaying, or recently dead pine trees.

Hemagglutinin Activities in Pearl Oyster, Pinctada fucata martensii, Hemolymph

open access: yes, 1988
Occurrence and partial characterization of hemagglutinin activities in the pearl oyster, Pinctada fucata martensii, hemolymph were investigated. Comparison of natural hemagglutinin activities against various kinds of erythrocytes (Table 1) revealed a ...

A Modified Standardized Method to Extract and Store Insect Hemolymph with Use of a Glass Capillary

open access: yesJournal of Apicultural Science, 2020
Hemolymph is the “blood” circulating in the entire insect body. Analysis of this fluid gives information about the condition of the insect. The most precise analyses are conducted on insects’ hemolymph suspended in 0.6% physiological saline (NaCl).
