The paper studies cuticular hydrocarbons of Dolichoderinae ants, identifies a new species in the Tapinoma nigerrimum group, and examines aggression behavior in T. magnum colonies.

The paper estimates age and growth of the Speartooth Shark using a small sample size and back-calculation techniques, finding an age-at-maturity of >12 years.

The paper tests if facultative endosymbionts in cereal aphids affect their sensitivity to pyrethroid insecticides, finding no link between endosymbiont presence and insecticide susceptibility.

The paper describes a new cichlid species, Lethrinops atrilabris, from Lake Malawi based on morphological characteristics and habitat.

This study examines how HE4 contributes to hyperoxia-induced alveolar damage in rats by activating ERK and p65, modulating MMP9 and TIMP1 pathways, and promoting fibrosis.

The paper describes the optimization of bat sampling methods in a sympatric colony to minimize animal stress and improve sample quality for ecological and virological studies.

The paper analyzes camera trap data to compare activity overlap between wolves, humans, and big game species in Hungary, finding that human disturbance has a greater impact on game activity than wolf presence.

This study quantifies the contribution of private game ranching and captive breeding operations in South Africa to the conservation of southern white rhinos, showing higher population growth compared to protected areas.

This study evaluates the wound healing and anti-inflammatory effects of Ajuga bracteosa-conjugated silver nanoparticles in Balb/c mice, finding they promote wound contraction and reduce inflammation.

This study analyzes felid population trends in Indian zoos to inform conservation strategies and breeding programs.

The paper describes a new Sympetrum species, Sympetrum bigeminus, distinguished by morphological differences in females from Sympetrum sanguineum.

The paper estimates abortion rates in tsetse flies from Zimbabwe, finding higher rates in artificial refuges and seasonal variations, but not age-related increases.

This study uses RNA-seq to analyze the venom complement and parthenogenesis mechanism of the parasitoid wasp Microctonus hyperodae, identifying key genes involved in host manipulation and asexual reproduction.

This study analyzes the phylogenetic relationships and evolutionary history of Lamiinae beetles from East of Marmara Basin, Turkey, and their relatives, using mitochondrial and nuclear genes.

This study shows near-anoxia induces sperm immobilisation and sustains viability in ant queens, but factors beyond anoxia are needed for long-term preservation.

The paper examines the impact of Neogene climate fluctuations and limited connectivity with diversity centers on the Western Palearctic net-winged beetle fauna, identifying relic species in Mediterranean refugia.

The paper restores the accurate body form of blue whales using photographs and skeletons, finding a hydrodynamic shape and estimating their mass at ~200 tonnes.

This study develops an algorithm to reduce disease spread in cattle by rewiring movements between herds, showing effectiveness in both epidemic and endemic scenarios.

This study examines morphological covariation between splanchnocranium and basicranium in Toy rabbits, finding significant asymmetry and allometric relationships, supporting paedomorphic growth patterns.

This study analyzes the kinetic behavior of eyelids in little owls using video recordings and anatomical/histological studies, revealing muscle interactions and structural variations.
