The paper uses local fishers' knowledge to assess shark and ray population declines in Western Ghana from 1980 to 2020, finding significant depletions linked to overfishing and IUU activities.

This study examines AV nodal function in giraffes during atrial fibrillation and ventricular tachycardia, finding prolonged PR intervals and slow ventricular responses consistent with unique cardiovascular adaptations.

The paper surveys aphidiine wasps in Australian grain landscapes, identifies key species, and provides a key for identification, highlighting their role in pest management.

The paper describes a data-poor fishery targeting large threatened rays in Indonesia and reports catch data from 2001-2005 and 2017-2018, highlighting declines and shifts in catch composition.

This study evaluates the impact of different dietary electrolyte balance levels on hematological and biochemical parameters of broilers under heat stress, finding significant effects on various blood and plasma indicators.

This study establishes regression models for estimating facial soft tissue thickness in chimpanzees, showing covariation with craniometric dimensions and interspecies compatibility with hominids similar to chimpanzees.

The paper estimates the population size and habitat association of Swaynes Hartebeest in Maze National Park using line-transect sampling and chi-square tests, finding no seasonal variation in population size and significant habitat preference for savannah grassland.

This study extracts and analyzes the essential oil from Callistemon citrinus and assesses its toxic effects on Tribolium castaneum, showing high mortality and repellent activity.

This study identifies genetic diversity in Bemisia tabaci populations in Qassim, Saudi Arabia using ISSR-PCR and COI analysis, revealing four genetic groups and confirming the presence of B biotypes.

The study examines breeding performance, survival, and growth of common carp in Nepal's fish farms using induced breeding and monitoring water quality and growth metrics.

This study investigates the transmission and biological effects of a torix group Rickettsia in bed bugs, finding maternal transmission and reduced development and fecundity without cytoplasmic incompatibility.

The paper monitors pyrethroid resistance in Anopheles darlingi in French Guiana and suggests metabolic resistance may be responsible for observed resistance without target gene mutations.

This study examines the effects of transport and altitude on stress hormones and oxidative stress in sheep, finding no significant changes in cortisol and T3 but concluding that transport and altitude cause stress.

This study shows artificial light at night disrupts circadian rhythms in great tits, with shifts in gene expression and metabolomic profiles indicating circadian disruption across tissues.

The paper identifies key stakeholders in integrated crops-livestock farming systems in West New Guinea and maps their roles and relationships through network analysis.

The paper shows that apparent negative density-dependent dispersal in tsetse flies is an artifact of flawed analysis, not a real biological phenomenon.

This study investigates the existence and characteristics of the myodural bridge in Gentoo penguins, finding it analogous to humans but with unique features.

The paper assesses geographic variation in threats to Egyptian Vultures along the eastern Mediterranean flyway using tracking, surveys, and interviews, finding differing mortality causes across regions.

Image3C enables single-cell analysis without species-specific reagents by using image-based clustering and CNN integration to detect cellular composition changes.

InSegtCone automates the segmentation of crystalline cones in arthropod compound eyes, achieving 60%-80% accuracy and 250x speed compared to manual labeling.
