Cooperative Breeding: A Question of Climate?
In some species, including humans, parents receive help with offspring care. A new comparative study suggests that birds breed cooperatively when environmental conditions vary. Further empirical and theoretical work will be required to understand the evolutionary significance of this insight.
متن کاملA question of breeding
Switzerland had plenty to feel gloomy about in the current global economic situation. But they had the added grist of a session on demographics that made grim listening. The world's population will grow by 50 per cent in the next four decades, rising from six billion to nine billion by 2050, the panel — including Enrico Giovanni, the chief statistician at the Organisation for Economic Cooperati...
متن کاملClimate and the distribution of cooperative breeding in mammals
Cooperative breeding systems, in which non-breeding individuals provide care for the offspring of dominant group members, occur in less than 1% of mammals and are associated with social monogamy and the production of multiple offspring per birth (polytocy). Here, we show that the distribution of alloparental care by non-breeding subordinates is associated with habitats where annual rainfall is ...
متن کاملWhat drives cooperative breeding?
Cooperative breeding, in which more than a pair of conspecifics cooperate to raise young at a single nest or brood, is widespread among vertebrates but highly variable in its geographic distribution. Particularly vexing has been identifying the ecological correlates of this phenomenon, which has been suggested to be favored in populations inhabiting both relatively stable, productive environmen...
متن کاملC Cooperative Breeding
Cooperative breeding is characterized by a combination of group living and alloparental care, i.e., the care of others’ offspring. Typically, young of previous broods remain in their natal territory and help raising subsequent offspring of dominant breeders. Hence, the characteristic of cooperative breeding is the joint occurrence of delayed dispersal of young with a propensity to help caring f...
