Abstract Environmental monitoring of local climatic variations plays a vital role in the research on global warming, species diversity, ecological sustainability, and so on. Traditional technologies, such as meteorological stations or satellite imagery, can give an overall environment picture but at high cost, energy consumption, with insufficient regional details. Here, networking system made low‐cost, maintenance‐free, distributed self‐powered wireless nodes is proposed, aimed establishing sensing for long‐term wide‐area monitoring. It demonstrated that, driven by gentle wind, these are able to monitor temperature, humidity, atmospheric pressure automatically, then transfer data receiving terminals wirelessly using triboelectric nanogenerators harvesting technologies.

Taking the beat of the Arctic: are lemming population cycles changing due to winter climate?

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2024, Volume and Issue: 291(2016)

Reports of fading vole and lemming population cycles persisting low populations in some parts the Arctic have raised concerns about spread these fundamental changes to tundra food web dynamics. By compiling 24 unique time series fluctuations across circumpolar region, we show that virtually all displayed alternating periods cyclic/non-cyclic over past four decades. Cyclic patterns were detected 55% ( n = 649 years pooled sites) with a median periodicity 3.7 years, non-cyclic not more frequent recent years. Overall, there was an indication for negative effect warm spells occurring during snow onset period preceding year on abundance. However, winter duration or early climatic conditions did differ average between cyclic periods. Analysis shows is presently no Arctic-wide collapse cycles, even though been sporadic at most sites last Although non-stationary dynamics appears common feature also past, continued warming may decrease frequency periodic irruptions consequences ecosystems.

Effects of Human Disturbance on Terrestrial Apex Predators

Diversity, Journal Year: 2021, Volume and Issue: 13(2), P. 68 - 68

Published: Feb. 9, 2021

The effects of human disturbance spread over virtually all ecosystems and ecological communities on Earth. In this review, we focus the terrestrial apex predators. We summarize their role in nature how they respond to different sources disturbance. Apex predators control prey smaller numerically via behavioral changes avoid predation risk, which turn can affect lower trophic levels. Crucially, reducing population numbers triggering responses are also that causes predators, may influence role. Some populations continue be at brink extinction, but others partially recovering former ranges, natural recolonization through reintroductions. Carnivore recovery is both good news for conservation a challenge management, particularly when occurs human-dominated landscapes. Therefore, conclude by discussing several management considerations that, adapted local contexts, favor predator functions nature.

Snow cover phenology has exhibited dramatic changes in the past decades. However, distribution and attribution of hemispheric scale snow anomalies remain unclear. Using satellite-retrieved products, ground observations, reanalysis climate variables, this study explored onset date, end duration days over Northern Hemisphere from 2001 to 2020. The latitudinal altitudinal distributions 20-year averaged are well represented by matrixes. validation results using 850 stations demonstrated that matrixes capture spatial variability at 95% significance level during overlapping period 2001–2017. Moreover, a delayed date an earlier (1.12 decade−1, p < 0.05) detected 2001–2020 based on In addition, analysis indicated dominates increased melting season temperature is key driving factor NH 2001–2020.

Global change risks a threatened species due to alteration of predator–prey dynamics

Abstract Although global change can reshape ecosystems by triggering cascading effects on food webs, indirect interactions remain largely overlooked. Climate‐ and land‐use‐induced changes in landscape cause shifts vegetation composition, which affect entire webs. We used simulations of forest dynamics movements interacting species, parameterized empirical observations, to predict the outcomes a large‐mammal web boreal forest. demonstrate that climate‐ landscapes exacerbate asymmetrical apparent competition between moose threatened caribou populations through wolf predation. increased prey mortalities came from both behavioral numerical responses, responses had an overwhelming effect. The increase was exacerbated cumulating land use over short term climate impacts long term, with higher impact use. Indirect trophic will be key understanding community under change.

Pathways to global-change effects on biodiversity: new opportunities for dynamically forecasting demography and species interactions

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2023, Volume and Issue: 290(1993)

In structured populations, persistence under environmental change may be particularly threatened when abiotic factors simultaneously negatively affect survival and reproduction of several life cycle stages, as opposed to a single stage. Such effects can then exacerbated species interactions generate reciprocal feedbacks between the demographic rates different species. Despite importance such feedbacks, forecasts that account for them are limited individual-based data on interacting perceived essential mechanistic forecasting—but rarely available. Here, we first review current shortcomings in assessing population community dynamics. We present an overview advances statistical tools provide opportunity leverage population-level abundances multiple infer stage-specific demography. Lastly, showcase state-of-the-art Bayesian method project Mediterranean shrub community.
