Due to the unique geographical features of large numbers, isolated by water and diverse formation histories, islands have become natural laboratories for ecological and evolutionary research. Islands have a high proportion of endemic species and disharmony in representing the species compared with that in the continent, which provides a good opportunity to explore the formation of island biodiversity. In this review, we focuse on island ecosystems and describes the progress of research in island biogeography in recent years from three aspects: formation, maintenance, and loss of island biodiversity.

Thus, domesticated individuals escaping into wild populations is a key conservation concern. In Prince William Sound, Alaska, over 700 million pink salmon () are released annually from hatcheries, providing a natural experiment to characterize the mechanisms underlying impacts to wild populations.

Background: The positive effects of mindfulness-based stress reduction (MBSR) on cognition, stress relief, and sleep have been well-documented. However, there is limited research on its potential benefits for older adults, particularly within vulnerable populations such as migrants. This study aimed to compare the impacts of MBSR with a health promotion program in individuals aged ≥55.

This study seeks to understand the association between immigration status and cognitive function in a representative sample of the US population and examine physical activity and nutritional intake's interaction with immigration status.
Method: The study cohort included 2,898 participants (673 immigrants and 2225 non-immigrants) from US National Health and Nutrition Examination Survey (NHANES) 2011-2014 who underwent at least one cognitive function test.

Introduction: Southern Africa has been inhabited by hunter-gatherers for at least 20,000 years and has received diverse immigration flows in the last 2000 years. The original inhabitants have interacted with the pastoralist migrants from Eastern Africa (∼2000 ybp), followed by the southern Bantu migration arriving some 1000 ybp, and more recently with the European and Asian settlers after the 17th century. Many of the original Khoekhoe and San inhabitants have either become extinct or have disappeared through admixture in South Africa (SA), in a sex-biased manner involving KhoeSan women.
