The effect of dispersal on asymptotic total population size in discrete- and continuous-time two-patch models.
Publication Type: Academic Journal
Source(s): Journal of mathematical biology [J Math Biol] 2023 Sep 21; Vol. 87 (4), pp. 60. Date of Electronic Publication: 2023 Sep 21.
Abstract: Many populations occupy spatially fragmented landscapes. How dispersal affects the asymptotic total population size is a key question for conservation management and the design of ecological corridors. Here, we provide a comprehensive overview of two-p...
High school science fair: School location trends in student participation and experience.
Publication Type: Academic Journal
Source(s): PloS one [PLoS One] 2023 Sep 11; Vol. 18 (9), pp. e0291049. Date of Electronic Publication: 2023 Sep 11 (Print Publication: 2023).
Abstract: The findings reported in this paper are based on surveys of U.S. high school students who registered and managed their science and engineering fair (SEF) projects through the online Scienteer website over the three years 2019/20, 2020/21, and 2021/22. ...
Phenological mismatch affects individual fitness and population growth in the winter moth.
Publication Type: Academic Journal
Source(s): Proceedings. Biological sciences [Proc Biol Sci] 2023 Aug 30; Vol. 290 (2005), pp. 20230414. Date of Electronic Publication: 2023 Aug 23.
Abstract: Climate change can severely impact species that depend on temporary resources by inducing phenological mismatches between consumer and resource seasonal timing. In the winter moth, warmer winters caused eggs to hatch before their food source, young oak...
Stationary status of discrete and continuous age-structured population models.
Publication Type: Academic Journal
Source(s): Mathematical biosciences [Math Biosci] 2023 Oct; Vol. 364, pp. 109058. Date of Electronic Publication: 2023 Aug 02.
Abstract: From Leonhard Euler to Alfred Lotka and in recent years understanding the stationary process of the human population has been of central interest to scientists. Population reproductive measure NRR (net reproductive rate) has been widely associated with...
Purging and accumulation of genetic load in conservation.
Publication Type: Academic Journal
Source(s): Trends in ecology & evolution [Trends Ecol Evol] 2023 Oct; Vol. 38 (10), pp. 961-969. Date of Electronic Publication: 2023 Jun 19.
Abstract: Our ability to assess the threat posed by the genetic load to small and declining populations has been greatly improved by advances in genome sequencing and computational approaches. Yet, considerable confusion remains around the definitions of the gen...
Changing Landscape of Routine Pediatric Surgery for Rural and Urban Children: A Report From the Child Health Evaluation of Surgical Services (CHESS) Group.
Publication Type: Academic Journal
Source(s): Annals of surgery [Ann Surg] 2023 Oct 01; Vol. 278 (4), pp. 530-537. Date of Electronic Publication: 2023 Jul 27.
Abstract: Objective: To describe the changes to routine pediatric surgical care over the past 2 decades for children living in urban and rural environments.Background: A knowledge gaps exists regarding trends in the location where routine pediatric surgical care...
Noise-induced dynamics in a single species model with Allee effect driven by correlated colored noises.
Publication Type: Academic Journal
Source(s): Journal of theoretical biology [J Theor Biol] 2023 Sep 21; Vol. 573, pp. 111610. Date of Electronic Publication: 2023 Aug 20.
Abstract: In this paper, a single species model with Allee effect driven by correlated colored noises is proposed and investigated. The stationary probability density of the model is obtained using the approximative Fokker-Planck equation, and its shape is discu...
Inclusive fitness forces of selection in an age-structured population.
Publication Type: Academic Journal
Source(s): Communications biology [Commun Biol] 2023 Sep 05; Vol. 6 (1), pp. 909. Date of Electronic Publication: 2023 Sep 05.
Abstract: Hamilton's force of selection acting against age-specific mortality is constant and maximal prior to the age of first reproduction, before declining to zero at the age of last reproduction. The force of selection acting on age-specific reproduction dec...
The impact of devolution on experienced health and well-being.
Publication Type: Academic Journal
Source(s): Social science & medicine (1982) [Soc Sci Med] 2023 Sep; Vol. 333, pp. 116139. Date of Electronic Publication: 2023 Aug 08.
Abstract: Devolution of health systems from national to local levels is a common focus of policymakers across the world. The overarching aim is to improve population health by better meeting the specific needs of local citizens. We examine the case of a coordina...
Generation time and seasonal migration explain variation in spatial population synchrony across European bird species.
Publication Type: Academic Journal
Source(s): The Journal of animal ecology [J Anim Ecol] 2023 Sep; Vol. 92 (9), pp. 1904-1918. Date of Electronic Publication: 2023 Jul 13.
Abstract: Spatial population synchrony is common among populations of the same species and is an important predictor of extinction risk. Despite the potential consequences for metapopulation persistence, we still largely lack understanding of what makes one spec...
