A roadmap towards predicting species interaction networks (across space and time).

Philos Trans R Soc Lond B Biol Sci 2021 Nov 20;376(1837):20210063. Epub 2021 Sep 20.

Sciences Biologiques, Université de Montréal, Montréal, Canada H2V 0B3.

Networks of species interactions underpin numerous ecosystem processes, but comprehensively sampling these interactions is difficult. Interactions intrinsically vary across space and time, and given the number of species that compose ecological communities, it can be tough to distinguish between a true negative (where two species never interact) from a false negative (where two species have not been observed interacting even though they actually do). Assessing the likelihood of interactions between species is an imperative for several fields of ecology. Read More

Anthropogenic land‒use impacts on the size structure of macroinvertebrate assemblages are jointly modulated by local conditions and spatial processes.

Environ Res 2021 Sep 16;204(Pt B):112055. Epub 2021 Sep 16.

Freshwater Centre, Finnish Environment Institute, PO Box 413, FI‒90014, Oulu, Finland. Electronic address:

Body size descriptors and associated resemblance measurements may provide useful tools for forecasting ecological responses to increasing anthropogenic land‒use disturbances. Yet, the influences of agriculture and urbanisation on the size structure of biotic assemblages have seldom been investigated in running waters. Using a comprehensive dataset on stream macroinvertebrates from 21 river basins across Western Finland, we assessed whether the structure of assemblages via changes in taxonomic composition and body size distributions responded predictably to anthropogenic land‒use impacts.

Biotic interactions are more often important at species' warm versus cool range edges.

Ecol Lett 2021 Aug 27. Epub 2021 Aug 27.

Department of Biology, McGill University, Montreal, Quebec, Canada.

Predicting which ecological factors constrain species distributions is a fundamental ecological question and critical to forecasting geographic responses to global change. Darwin hypothesised that abiotic factors generally impose species' high-latitude and high-elevation (typically cool) range limits, whereas biotic interactions more often impose species' low-latitude/low-elevation (typically warm) limits, but empirical support has been mixed. Here, we clarify three predictions arising from Darwin's hypothesis and show that previously mixed support is partially due to researchers testing different predictions. Read More

Entropy as an Objective Function of Optimization Multimodal Transportations.

Entropy (Basel) 2021 Jul 24;23(8). Epub 2021 Jul 24.

Department of Economics and Finance, Educational and Scientific Institute of Marine Business, Odesa National Maritime University, 65029 Odesa, Ukraine.

This article considers the use of the entropy method in the optimization and forecasting of multimodal transport under conditions of risks that can be determined simultaneously by deterministic, stochastic and fuzzy quantities. This will allow to change the route of transportation in real time in an optimal way with an unacceptable increase in the risk at one of its next stages and predict the redistribution of the load of transport nodes. The aim of this study is to develop a mathematical model for the optimal choice of an alternative route, the best for one or more objective functions in real time. Read More

SDM-CropProj - A model-assisted framework to forecast crop environmental suitability and fruit production.

MethodsX 2021 23;8:101394. Epub 2021 May 23.

Escola Superior Agrária, Instituto Politécnico de Viana do Castelo, Praça Gen. Barbosa 44, 4900-347 Viana do Castelo, Portugal.

The effects of climate change (CC) will impact species ranges, and crops are no exception. Anticipating these changes through forecasting the environmentally suitable area of crops would help to reduce or mitigate the impact and adapt ecological and economic strategies. To forecast the CC effects on crops, we describe here a model-assisted framework (hereafter SDM-CropProj) that combines two modelling steps to be implemented in sequence: i) a multi-technique calibration process and ensemble-forecasting approach to predict the current and future environmental suitability of target crops; ii) a parsimonious univariate log-log linear model to relate the average total annual production to the current SDM-based suitable area.

Reservoir computing on epidemic spreading: A case study on COVID-19 cases.

Phys Rev E 2021 Jul;104(1-1):014308

Physics and Applied Mathematics Unit, Indian Statistical Institute, 203 B. T. Road, Kolkata 700108, India.

A reservoir computing based echo state network (ESN) is used here for the purpose of predicting the spread of a disease. The current infection trends of a disease in some targeted locations are efficiently captured by the ESN when it is fed with the infection data for other locations. The performance of the ESN is first tested with synthetic data generated by numerical simulations of independent uncoupled patches, each governed by the classical susceptible-infected-recovery model for a choice of distributed infection parameters.

Restoration of marine ecosystems: Understanding possible futures for optimal outcomes.

Sci Total Environ 2021 Nov 2;796:148845. Epub 2021 Jul 2.

College of Arts, Society and Education, James Cook University, Queensland 4811, Australia.

Accelerating declines in the extent, quality and functioning of the world's marine ecosystems have generated an upsurge in focus on practical solutions, with ecosystem restoration becoming an increasingly attractive mitigation strategy for systems as diverse as coral reefs, mangroves and tidal flats. While restoration is popular because it promises positive outcomes and a return to something approaching unimpacted condition and functioning, it involves substantial public and private investment, both for the initial restoration activity and for on-going maintenance of the restored asset. This investment often affords one big chance to get things right before irretrievable damage is done. Read More

Front Plant Sci 2021 23;12:667964. Epub 2021 Jun 23.

State Key Laboratory of Subtropical Silviculture, Zhejiang A&F University, Hangzhou, China.

Nutrient resorption can affect plant growth, litter decomposition, and nutrient cycling. Although the effects of nitrogen (N) and biochar fertilizers on soil nutrient concentrations and plant nutrient uptake have been studied, an understanding of how combined applications of N and biochar affect plant nutrient resorption in plantations is lacking. In this study, we applied N (0, 30, 60, and 90 kg N ha yr defined as N0, N30, N60, and N90, respectively) and biochar (0, 20, and 40 t biochar ha defined as BC0, BC20, and BC40, respectively) to the soil of a Moso bamboo plantation.

Effects of stochasticity on the length and behaviour of ecological transients.

J R Soc Interface 2021 07 7;18(180):20210257. Epub 2021 Jul 7.

Department of Mathematics, Bowdoin College, Brunswick, ME 04011, USA.

There is a growing recognition that ecological systems can spend extended periods of time far away from an asymptotic state, and that ecological understanding will therefore require a deeper appreciation for how long ecological transients arise. Recent work has defined classes of deterministic mechanisms that can lead to long transients. Given the ubiquity of stochasticity in ecological systems, a similar systematic treatment of transients that includes the influence of stochasticity is important. Read More

Understanding norovirus reporting patterns in England: a mixed model approach.

BMC Public Health 2021 06 28;21(1):1245. Epub 2021 Jun 28.

Institute of Infection, Veterinary and Ecological Sciences, University of Liverpool, Liverpool, UK.

Background: Norovirus has a higher level of under-reporting in England compared to other intestinal infectious agents such as Campylobacter or Salmonella, despite being recognised as the most common cause of gastroenteritis globally. In England, this under-reporting is a consequence of the frequently mild/self-limiting nature of the disease, combined with the passive surveillance system for infectious diseases reporting. We investigated heterogeneity in passive surveillance system in order to improve understanding of differences in reporting and laboratory testing practices of norovirus in England. Read More

Soil aeration rather than methanotrophic community drives methane uptake under drought in a subtropical forest.

Sci Total Environ 2021 Oct 5;792:148292. Epub 2021 Jun 5.

School of Life Sciences, University of Chinese Academy of Sciences, Yuquan Road, Beijing 100049, China.

Little information is available about the effects of drought on soil methane (CH) uptake and the underlying feedback of the soil microbial community in forest biomes. More importantly, a meta-analysis of the current literature on this topic revealed that there are virtually no data available in subtropical forests. To fill the abovementioned knowledge gap, we carried out a 3-year investigation of in situ CH efflux under drought in a subtropical forest, and found that drought significantly increased soil CH uptake (P < 0.
