Complementary habitat use by wild bees in agro-natural landscapes.
Human activity causes abrupt changes in resource availability across the landscape. In order to persist in human-altered landscapes organisms need to shift their habitat use accordingly. Little is known about the mechanisms by which whole communities persist in human-altered landscapes, including the role of complementary habitat use. We define complementary habitat use as the use of different ...
متن کاملSexy males and choosy females on exploded leks: correlates of male attractiveness in the Little Bustard.
In their choice of mates, females may use alternative tactics, including a comparative assessment of males in a population, using one or several relative preference criteria. Traits involved in female choice should presumably be variable between, but not within males, thus potentially providing reliable cues of male identity and quality for prospecting females. In lekking species, sexual select...
متن کاملCourtship behaviour in a lekking species: individual variations and settlement tactics in male little bustard.
We analysed the display behaviour of male little bustard Tetrax tetrax to identify displays that are used in the context of male-male competition and those that are used for attracting females. Courtship was the main activity of males during the breeding season. Calling activity occurred throughout the day, and leks were attended for more than 4 months. Male sexual displays included snort call,...

متن کاملDiet Diversity in Pastoral and Agro-pastoral Households in Ugandan Rangeland Ecosystems.
We explore how diet diversity differs with agricultural seasons and between households within pastoral and agro-pastoral livelihood systems, using variety of foods consumed as a less complex proxy indicator of food insecurity than benchmark indicators like anthropometry and serum nutrients. The study was in the central part of the rangelands in Uganda. Seventy nine households were monitored for...
