Why we Should Study Solitary Species to Understand the Costs of Group‐Living
Ethology, EarlyView.It's easier to measure the benefits than the costs of a trait. Solitary species benefit by avoiding the costs of group living. Thus, measuring benefits of solitary living informs us about the costs of group living. ABSTRACT While for decades behavioral ecologists have studied the benefits of group living, measuring its costs has been more difficult. It

Ethology, EarlyView.Corpses are repositories of information about the cause of death. The distress of the bereaved acts as an honest signal drawing conspecifics to the body, enabling them to learn quickly about the death, adapt their behaviour, and spread knowledge of threats across multiple social levels.

Jurnal Kelautan TropisBlue swimming crab (Portunus pelagicus) is one of Indonesia’s essential fishery commodities, but overfishing has depleted its population. Aquaculture, as an alternative to produce this crab, is hampered by high levels of cannibalism.

Fisheries Management and Ecology, EarlyView.ABSTRACT Changes in angling response were studied over a period of three years in a natural, previously unfished population of northern pike. Standardized angling sessions took place during two weeks in spring and autumn with three bait types: bright‐ and natural‐colored soft plastic baits and a dead baitfish.

Journal of Applied Entomology, EarlyView.ABSTRACT Gryllodes sigillatus is an increasingly important species in edible insect production, yet the optimal rearing density for this species under commercial conditions remains poorly defined. This study evaluated the effects of five rearing densities (1.5, 2, 2.5, 3 and 4 mL of newly hatched nymphs, corresponding to approximately 0.144–0.385 ...

Journal of Applied Entomology, EarlyView.ABSTRACT Termites are eusocial insects that maintain cohesion and exchange information through frequent physical interactions among nestmates. This social organisation underlies the principle of horizontal insecticide transfer, which is widely exploited as a termite control strategy.

Early‐life temperature drives recruitment success in Eurasian perch (Perca fluviatilis) populations
Journal of Fish Biology, EarlyView.Abstract Interannual fluctuations in the abundance of young‐of‐the‐year (YOY) European perch (Perca fluviatilis) were studied in two large French peri‐alpine lakes using a 12‐year dataset of late summer hydroacoustic surveys. Previous research has highlighted the importance of temperature.
