A data set of distributed global population and water withdrawal from 1960 to 2020.

Publication Type: Academic Journal

Source(s): Scientific data [Sci Data] 2022 Oct 21; Vol. 9 (1), pp. 640. Date of Electronic Publication: 2022 Oct 21.

Authors:

Abstract: Population and water withdrawal data sets are currently faced with difficulties in collecting, processing and verifying multi-source time series, and the spatial distribution characteristics of long series are also relatively lacking. Time series is th...

Intrinsic nonlinear dynamics drive single-species systems.

Publication Type: Academic Journal

Source(s): Proceedings of the National Academy of Sciences of the United States of America [Proc Natl Acad Sci U S A] 2022 Nov; Vol. 119 (44), pp. e2209601119. Date of Electronic Publication: 2022 Oct 24.

Abstract: The importance of oscillations and deterministic chaos in natural biological systems has been discussed for several decades and was originally based on discrete-time population growth models (May 1974). Recently, all types of nonlinear dynamics were sh...

Using gridCoal to assess whether standard population genetic theory holds in the presence of spatio-temporal heterogeneity in population size.

Publication Type: Academic Journal

Source(s): Molecular ecology resources [Mol Ecol Resour] 2022 Nov; Vol. 22 (8), pp. 2941-2955. Date of Electronic Publication: 2022 Jul 15.

Abstract: Spatially explicit population genetic models have long been developed, yet have rarely been used to test hypotheses about the spatial distribution of genetic diversity or the genetic divergence between populations. Here, we use spatially explicit coale...

Spatial structure of city population growth.

Publication Type: Academic Journal

Source(s): Nature communications [Nat Commun] 2022 Oct 08; Vol. 13 (1), pp. 5931. Date of Electronic Publication: 2022 Oct 08.

Abstract: We show here that population growth, resolved at the county level, is spatially heterogeneous both among and within the U.S. metropolitan statistical areas. Our analysis of data for over 3,100 U.S. counties reveals that annual population flows, resulti...

Guidance for management of free-roaming community cats: a bioeconomic analysis.

Publication Type: Academic Journal

Source(s): Journal of feline medicine and surgery [J Feline Med Surg] 2022 Oct; Vol. 24 (10), pp. 975-985. Date of Electronic Publication: 2021 Nov 29.

Abstract: Objectives: This study used computer simulation modeling to estimate and compare costs of different free-roaming cat (FRC) management options (lethal and non-lethal removal, trap-neuter-return, combinations of these options and no action) and their abi...

Factors impinge on the development of a smart city: a field study.

Publication Type: Academic Journal

Source(s): Environmental science and pollution research international [Environ Sci Pollut Res Int] 2022 Dec; Vol. 29 (57), pp. 86298-86307. Date of Electronic Publication: 2022 Jan 08.

Abstract: Smart city aims at amassed connectivity at various levels in the midst of citizens, as well as amid the administration and the daily growing population. India is one of the developing countries where population growth is one of the significant areas to...

Aging in Nigeria: A Growing Population of Older Adults Requires the Implementation of National Aging Policies.

Publication Type: Academic Journal

Source(s): The Gerontologist [Gerontologist] 2022 Oct 19; Vol. 62 (9), pp. 1243-1250.

Abstract: While the continent of Africa currently has the lowest share of adults aged 60 and older in its population among all world regions, the total number of older Africans is projected to triple between 2020 and 2050. Nigeria-Africa's leading economy and mo...

Harvesting can stabilise population fluctuations and buffer the impacts of extreme climatic events.

Publication Type: Editorial & Opinion

Source(s): Ecology letters [Ecol Lett] 2022 Apr; Vol. 25 (4), pp. 863-875. Date of Electronic Publication: 2022 Feb 01.

Abstract: Harvesting can magnify the destabilising effects of environmental perturbations on population dynamics and, thereby, increase extinction risk. However, population-dynamic theory predicts that impacts of harvesting depend on the type and strength of den...

Socioecology and fiction.

Publication Type: Academic Journal

Source(s): The Behavioral and brain sciences [Behav Brain Sci] 2022 Nov 18; Vol. 45, pp. e280. Date of Electronic Publication: 2022 Nov 18.

Authors:

Abstract: We argue that the generation and enjoyment of imaginary worlds do not necessarily rely on an evolved preference for exploration. Rather, we suggest that culture is shaped by socioecological facts on the ground, and we hypothesize about the role of resi...

Temporal correlations among demographic parameters are ubiquitous but highly variable across species.

Publication Type: Editorial & Opinion

Source(s): Ecology letters [Ecol Lett] 2022 Jul; Vol. 25 (7), pp. 1640-1654. Date of Electronic Publication: 2022 May 24.

Abstract: Temporal correlations among demographic parameters can strongly influence population dynamics. Our empirical knowledge, however, is very limited regarding the direction and the magnitude of these correlations and how they vary among demographic paramet...
