Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Other Life Sciences
The unrivalled growth in e-commerce of animals and plants presents an unprecedented opportunity to monitor wildlife trade to inform conservation, biosecurity, and law enforcement. Using the Internet to quantify the scale of the wildlife trade (volume, frequency) is a relatively recent and rapidly developing approach, which currently lacks an accessible framework for locating relevant websites and [...]
Local landscape position impacts demographic rates in a widespread North American steppe bunchgrass
Published: 2020-05-27
Subjects: Ecology and Evolutionary Biology, Life Sciences, Population Biology
[this article now published at Ecosphere: https://doi.org/10.1002/ecs2.3351] Understanding the environmental drivers of demographic rates and population dynamics over space and time is critical for anticipating how species will respond to climate change. While the influence of temporal environmental variation and large environmental gradients are well recognized, less is known about how local [...]
Crowdsourcing global perspectives in ecology using social media
Published: 2020-05-13
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Transparent, open, and reproducible research is still far from routine, and the full potential of open science has not yet been realized. Crowdsourcing––defined as the usage of a flexible open call to a heterogeneous group of individuals to recruit volunteers for a task ––is an emerging scientific model that encourages larger and more outwardly transparent collaborations. While crowdsourcing, [...]

Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Fieldwork has played a critical role in the development of landscape ecology, and it remains essential for addressing contemporary challenges such as understanding the landscape ecology of global change. Advances in technology have expanded the scope of fieldwork to include the deployment of drones and other sensors, and in recent years, researchers have expressed concerns that traditional [...]
Small-scale farming in drylands: New models for resilient practices of millet and sorghum cultivation
Published: 2020-05-11
Subjects: Agriculture, Life Sciences, Other Social and Behavioral Sciences, Social and Behavioral Sciences
Finger millet, pearl millet and sorghum are amongst the most important drought-tolerant crops worldwide. They constitute primary staple crops in drylands, where their production is known to date back over 5000 years ago. Compared to other crops, millets and sorghum have received less attention until very recently, and their production has been progressively reduced in the last 50 years. Here, we [...]
Associations between habitat quality and body size in the Carpathian land snail Vestia turgida: species distribution model selection and assessment of performance.

Subjects: Biodiversity, Life Sciences
Associations between habitat quality and body size in the Carpathian land snail Vestia turgida: species distribution model selection and assessment of performance. Tytar V., Baidashnikov O. – Species distribution models (SDMs) are generally thought to be good indicators of habitat suitability, and thus of species’ performance, consequently SDMs can be validated by checking whether the areas [...]
Rapid-warming tolerance correlates with tolerance to slow warming but not growth at non-optimal temperatures in zebrafish
Published: 2020-05-08
Subjects: Comparative and Evolutionary Physiology, Life Sciences, Physiology
Global warming is predicted to increase both acute and prolonged thermal challenges for aquatic ectotherms. Severe short and medium-term thermal stress over hours to days may cause mortality, while longer sub-lethal thermal challenges may cause performance declines. The interrelationship between the responses to short, medium and longer thermal challenges is unresolved. We asked if the same [...]
Why spatial scale matters in predicting synchrony of ecological disruption
Published: 2020-05-08
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Arising from: C. Trisos et al. Nature 580, 496–501, https://doi.org/10.1038/s41586-020-2189-9 (2020). ABSTRACT The fundamental assumption behind this provocative study (Trisos et al. 2020) is that current and future climatic tolerance limits for a species can be inferred from the last 170 years of climate records within its current distribution. Using this approach, the authors project the [...]
Climate change as a catalyst of social evolution
Published: 2020-05-08
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Evolution, Life Sciences
Anthropogenic climatic change will be a major factor shaping natural populations over the foreseeable future. The scope of this issue has spawned the integrative field of global change biology, which is chiefly concerned with identifying vulnerabilities of natural systems to climate change and integrating these into models of biodiversity loss. Meanwhile, there remains considerable latitude for [...]
Mapping the past, present and future research landscape of paternal effects
Published: 2020-05-07
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences, Medicine and Health Sciences, Other Medicine and Health Sciences, Physiology
Although in all sexually reproducing organisms, an individual has a mother and a father, non-genetic inheritance has been predominantly studied in mothers. Paternal effects have been far less frequently studied, until recently. In the last five years, research on environmentally induced paternal effects has grown rapidly in the number of publications and diversity of topics. Motivations for [...]
Assessing Raspberry Shake and Boom sensors for recording African elephant acoustic vocalizations

In this work we assess the performance of the Raspberry Shake and Boom (RS&B) sensor package for detecting and monitoring African elephants (Loxodonta africana). This is the first documented test of this particular unit for recording animal behaviour; the unit was originally designed for detecting tectonic earthquakes and low frequency (<50 Hz) atmospheric acoustics. During a four day [...]
Strengthening the evidence base for temperature-mediated phenological asynchrony and its impacts
Published: 2020-05-05
Subjects: Ecology and Evolutionary Biology, Life Sciences, Population Biology
Climate warming has caused the seasonal timing of many components of ecological food chains to advance (Thackeray et al. 2010, 2016). Differential shifts lead to phenological asynchrony, often referred to as trophic mismatch when it is detrimental for consumers (Cushing 1990). In the context of trophic interactions, it has been suggested that consumers will shift their phenology to adapt to [...]
Trophic cascades and connectivity in coastal benthic marine ecosystems: a meta-analysis of experimental and observational research
Published: 2020-05-03
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Marine Biology, Terrestrial and Aquatic Ecology
Predators often exert top-down control on lower trophic levels, such that their removal or addition can trigger trophic cascades. Despite coastal ecosystems containing well known trophic cascades, the abiotic and biotic factors governing the occurrence and strength of these cascades are still unclear. We worked to explain the variability of trophic cascades in benthic marine ecosystems by [...]
A Beginner’s Guide to Conducting Reproducible Research
Published: 2020-05-02
Subjects: Ecology and Evolutionary Biology, Life Sciences, Research Methods in Life Sciences
Reproducible research is widely acknowledged as an important tool for improving science and reducing harm from the "replication crisis", yet research in most fields within biology remains largely irreproducible. In this article, we make the case for why all research should be reproducible, explain why research is often not reproducible, and offer a simple framework that researchers can use to [...]
Understanding Non-genetic Inheritance: Insights from Molecular-Evolutionary Crosstalk
Published: 2020-05-01
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences
Understanding the evolutionary and ecological roles of non-genetic inheritance is daunting due to the complexity and diversity of epigenetic mechanisms. We draw on precise insights from molecular structures and events to identify three general features of non-genetic inheritance systems that are central to broader investigations: (i) they are functionally interdependent with, rather than separate [...]
