Bird Distribution in Biotopes of Open Agricaltural Lands in Breeding Season Based on comparative analysis of the vegetation structure in fields of different crops and taking into account intensity of land cultivation and types of avifauna communities formed in these fields, we identified five groups of fields in the Left-Bank Polissya and Wood-and-Steppe zone of Ukraine. The greatest number of breeding species and the most abundant species are in the first group (cereals, flax, white mustard, and buckwheat). The largest total average density, the highest average density of breeding species with nesting of two characteristic species is typical for fields of the second group (rapeseed and peas). The smallest proportion of breeding birds and the large dominant proportion were seen in low crops and in dense closed crops (soybean, lupine), these values are slightly higher than those in fields of beet and potatoes.

The breeding biology of tree frog, Polypedates teraiensis was studied during the breeding season at Mizoram University Campus. It was found that sound production by male during the breeding season was primarily a reproductive function and advertisement calls attract females to the breeding areas and announce other males that a given territory is occupied. The aim of this study was to provide the detailed information on the breeding behaviour and the advertisement calls of Polypedates teraiensis. The morphometric measurements of the amplecting pairs (males and females) for sexual dimorphism along with clutch sizes were also studied.
