Hunting, age structure, and horn size distribution in bighorn sheep
Sign Up to like & getrecommendations! Published in 2017 at "Journal of Wildlife Management"
DOI: 10.1002/jwmg.21259
Abstract: Trophy hunting, the selective removal of animals for human recreation, can contribute to conservation when appropriately managed. Yet, little is known about how harvest rates or different definitions of trophy affect age structure and trophy… read more here.

The demographic dividend is more than an education dividend
Sign Up to like & getrecommendations! Published in 2020 at "Proceedings of the National Academy of Sciences of the United States of America"
DOI: 10.1073/pnas.2012286117
Abstract: The demographic dividend has long been viewed as an important factor for economic development and provided a rationale for policies aiming at a more balanced age structure through birth control and family planning. Assessing the… read more here.

Empirically based spatial projections of US population age structure consistent with the shared socioeconomic pathways
Sign Up to like & getrecommendations! Published in 2019 at "Environmental Research Letters"
DOI: 10.1088/1748-9326/ab4a3a
Abstract: Spatially-explicit population projections by age are increasingly needed for understanding bilateral human-environment interactions. Conventional demographic methods for projecting age structure experience substantial challenges at small spatial scales. In search of a potentially better performing alternative,… read more here.

DOI: 10.1093/eurpub/ckz186.582
Abstract: Against the background of urbanization and aging and the aim to design age-friendly cities, it is crucially important to understand whether and why older adults’ health may benefit from being surrounded by older peers mainly,… read more here.

Trends in the size and age structure of marine fishes
Sign Up to like & getrecommendations! Published in 2018 at "ICES Journal of Marine Science"
DOI: 10.1093/icesjms/fsy180
Abstract: Size-selective harvesting is expected to reduce the average age and weight of commercially exploited fishes. The loss of larger, older fish has been hypothesized to negatively affect metrics of population viability, such as spawning behaviour,… read more here.

DOI: 10.1186/s12889-022-12717-9
Abstract: Background From 1982 to 2010, the country’s crude death rate (CDR) dropped sharply, fluctuated, and finally slightly declined. There is a big difference in CDR between urban and rural areas. From 1982 to 1990, the… read more here.

DOI: 10.14232/ejqtde.2019.1.30
Abstract: We show a detailed study on the dynamics of a neutral delay differential population model with age structure in the prey species. By selecting the mature delay as a bifurcation parameter, we obtain the stability… read more here.

DOI: 10.3390/biology11060898
Abstract: Simple Summary Age determination is very important for observing life history traits, evaluating vulnerable life stages, and setting proper management and conservation strategies. Age determination in animals has always been tricky. Among other approaches, skeletochronology,… read more here.
