Holding on or heading up? The roosting preferences of brown- and white-feathered laying hen pullets [PDF]

open access: yesPoultry Science
Although laying hens are known to be motivated to roost as high as possible and to use a perch that allows them to grasp, little is known about how these behaviours develop in young birds.

Similarity and Genetic Variation of Climbing Perch, Anabas testudineus (Bloch, 1792), From Java, Sumatra, and Kalimantan Islands, Indonesia [PDF]

open access: yesScientifica
Climbing perch, Anabas testudineus, is an economically important freshwater fish in Indonesia. The climbing perch, also known as betok, has emerged as a prominent species in aquaculture due to its air-breathing ability, which allows the climbing perch to
