The ecology of zoonotic parasites in the Carnivora.

Trends Parasitol 2021 Sep 17. Epub 2021 Sep 17.

Odum School of Ecology, University of Georgia 140 E. Green Street Athens, GA 30602, USA; Center for the Ecology of Infectious Diseases, University of Georgia 203 D.W. Brooks Drive Athens, GA 30602, USA.

The order Carnivora includes over 300 species that vary many orders of magnitude in size and inhabit all major biomes, from tropical rainforests to polar seas. The high diversity of carnivore parasites represents a source of potential emerging diseases of humans. Zoonotic risk from this group may be driven in part by exceptionally high functional diversity of host species in behavioral, physiological, and ecological traits. Read More

Causal assumptions and causal inference in ecological experiments.

Trends Ecol Evol 2021 Sep 15. Epub 2021 Sep 15.

Carey Business School, Johns Hopkins University, Baltimore, MD, USA; Department of Environmental Health and Engineering, a joint department of the Bloomberg School of Public Health and the Whiting School of Engineering, Johns Hopkins University, Baltimore, MD, USA. Electronic address:

Causal inferences from experimental data are often justified based on treatment randomization. However, inferring causality from data also requires complementary causal assumptions, which have been formalized by scholars of causality but not widely discussed in ecology. While ecologists have recognized challenges to inferring causal relationships in experiments and developed solutions, they lack a general framework to identify and address them. Read More

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.

Drivers of harmful algal blooms in coastal areas of Eastern Mediterranean: a machine learning methodological approach.

Math Biosci Eng 2021 07;18(5):6484-6505

Department of Marine Sciences, Faculty of Environment, University of the Aegean, University Hill, GR81100, Mytilene, Greece.

Harmful algal species are present in the Mediterranean Sea and are often associated with toxic events affecting the nearby coastal zones. The presence of 18 marine microalgae, at genus level, associated with potentially harmful characteristics was predicted using a number of machine learning techniques based exclusively on a small set of abiotic variables, already identified as drivers of blooms. Random Forest (RF) algorithm achieved the best predictive performance by correctly identifying the presence of most genera with a mean of 89. Read More

Smart allocation of restoration funds over space and time.

Ecol Appl 2021 Sep 12:e02448. Epub 2021 Sep 12.

Institute for Future Environments, Queensland University of Technology, Garden's Point, Queensland, 4000, Australia.

A challenge for natural area managers is to ensure that public expenditure on land restoration is cost-effective, efficient and transparent but this is difficult to achieve in practice, especially when there are many possible projects across multiple years. Here we develop a 'roadmap' for investment in land restoration. It explicitly considers space, time and their interaction, in relation to ecological outcomes and restoration costs (and their variation in time and space). Read More

Shape-shifting: changing animal morphologies as a response to climatic warming.

Trends Ecol Evol 2021 Aug 19. Epub 2021 Aug 19.

Centre for Integrative Ecology, School of Life and Environmental Sciences, Deakin University, Burwood, Victoria 3125, Australia.

Many animal appendages, such as avian beaks and mammalian ears, can be used to dissipate excess body heat. Allen's rule, wherein animals in warmer climates have larger appendages to facilitate more efficient heat exchange, reflects this. We find that there is widespread evidence of 'shape-shifting' (changes in appendage size) in endotherms in response to climate change and its associated climatic warming. Read More

Integrating thermal infrared stream temperature imagery and spatial stream network models to understand natural spatial thermal variability in streams.

J Therm Biol 2021 Aug 12;100:103028. Epub 2021 Jun 12.

Supervisory Research Landscape Ecologist at the U.S. Geological Survey, Forest and Rangeland Ecosystem Science Center, Cascadia Field Station; University of Washington School of Environmental and Forest Sciences, Box 352100 Seattle, WA 98195, USA.

Under a warmer future climate, thermal refuges could facilitate the persistence of species relying on cold-water habitat. Often these refuges are small and easily missed or smoothed out by averaging in models. Thermal infrared (TIR) imagery can provide empirical water surface temperatures that capture these features at a high spatial resolution (<1 m) and over tens of kilometers. Read More

[A review of research on the urban thermal environment effects of green quantity].

Ying Yong Sheng Tai Xue Bao 2020 Aug;31(8):2804-2816

School of Architecture and Design, China University of Mining and Technology, Xuzhou 221116, Jiangsu, China.

The regulative function of green quantity in urban thermal environment is an important topic in urban studies. Here, we reviewed the concepts and developments of green quantity, the measurements of green quantity and urban thermal environment, the relevance between green quantity and urban thermal environment, and its implications for urban planning. After summarizing domestic and international research processes, we put forward four prospective directions: 1) improving the methods for three-dimensional investigation of green quantity, 2) developing means for urban thermal environment monitoring and forecasting, 3) establishing an index system for three-dimensional pattern of urban green quantity, and 4) creating three-dimensional analytical methods to quantify the relationship between green quantity and urban thermal environment.

Bias assessments to expand research harnessing biological collections.

Trends Ecol Evol 2021 Sep 3. Epub 2021 Sep 3.

Department of Life Sciences, Texas A&M University-Corpus Christi, Corpus Christi, TX 78412, USA. Electronic address:

Biological collections are arguably the most important resources for investigations into the impacts of human activities on biodiversity. However, the apparent opportunities presented by museum-derived datasets have not resulted in consistent or widespread use of specimens in ecology outside phenological research and species distribution modeling. We attribute this gap between opportunity and application to biases introduced by collectors, curators, and preservation practices and an imperfect understanding of these biases and how to mitigate them.
