Researchers found that blind naked mole-rats disperse from their natal colonies to seek new partners and form new colonies, challenging the assumption that inbreeding is the norm for these eusocial creatures. The study also revealed that outbreeding is the preferred breeding system of choice for mole-rats.
Research reveals penguins can quickly acclimate to tourists visiting their breeding colonies, with reduced stress levels after brief exposure. After 10 days of repeated human visits, penguin stress levels decreased significantly, suggesting a possible long-term adaptation to ecotourism.
Researchers have found that migratory birds' winter habitats influence their breeding success by affecting arrival time and physical condition. American redstarts in wetter environments maintained better body mass and robust condition, while those in drier environments lost mass and showed signs of deteriorating condition.
A study by Ohio State University researchers found that high-testosterone males were more likely to fertilize females other than their mates, resulting in fewer offspring with their own mates. Conversely, these males produced more offspring with the mates of their neighbors.
