The population dynamics of clustered consumer-resource spatial patterns: Insights from the demographics of a Turing mechanism.
Proc Natl Acad Sci U S A

In ecology, Alan Turing's proposed activation-inhibition mechanism has been abstracted as corresponding to several ecological interaction types to explain pattern formation in ecosystems. Consumer-resource interactions have strong theoretical arguments linking them to both the Turing mechanism and pattern formation, but there is little empirical support to demonstrate these claims. Here, we connect several lines of evidence to support the proposition that consumer-resource interactions can create empirically observed spatial patterns through a mechanism similar to Turing's theory.

Introduction: Alcohol-associated liver disease (ALD) disproportionately impacts men, racial and ethnic minorities, and individuals of low socioeconomic status; however, it's unclear how recent increases in ALD burden have impacted these disparities. We aimed to describe trends in racial, ethnic and socioeconomic disparities in alcohol-associated hospital encounters.
Methods: We conducted a retrospective cohort study of adult hospital encounters with alcohol-associated diagnoses from three health systems between January 2016 and December 2021.
Physical activity, Vitamin D, and all-cause/cardiovascular mortality: a prospective study in older Chinese adults.
BMC Geriatr
January 2025
Department of Geriatrics, Tongji Hospital of Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China.
Background: Physical activity was associated with the risk of all-cause and cardiovascular mortality. However, little is known about older adults, especially those aged over 80 years.
Methods: 2863 older adults in the Chinese Longitudinal Healthy Longevity Survey (CLHLS) were enrolled.
Female reproductive ageing persists despite high infanticide risk in chacma baboons and geladas.

Department of Anthropology, Stony Brook University, Stony Brook, NY, USA.
Across mammals, fertility and offspring survival are often lowest at the beginning and end of females' reproductive careers. However, extrinsic drivers of reproductive success-including infanticide by males-could stochastically obscure these expected age-related trends. Here, we modelled reproductive ageing trajectories in two cercopithecine primates that experience high rates of male infanticide: the chacma baboon () and the gelada ().

Bacterial Diseases of Livestock Research Unit, National Animal Disease Center, Agricultural Research Service, 1920 Dayton Ave, Ames, IA, 50010, USA.
Background: Mycobacterium bovis BCG is the human tuberculosis vaccine and is the oldest vaccine still in use today with over 4 billion people vaccinated since 1921. The BCG vaccine has also been investigated experimentally in cattle and wildlife by various routes including oral and parenteral. Thus far, oral vaccination studies of cattle have involved liquid BCG or liquid BCG incorporated into a lipid matrix.
