1. Advances in datalogging technologies have provided a way to monitor the movement of individual animals at unprecedented spatial and temporal scales, both large and small. When used in conjunction with social network analyses, these data can provide insight into fine scale associative behaviors. The variety of technologies demand continuous progress in workflows to translate data streams from [...]
Participatory mapping of aquatic invasive species: a demonstration in a coastal lagoon
Published: 2020-10-15
Subjects: Biodiversity, Life Sciences, Marine Biology, Other Life Sciences, Research Methods in Life Sciences
Aquatic Invasive species (AIS) are a growing driver of change across marine and freshwater ecosystems but spatially-explicit information is seldom available for supporting management actions and decision making. Here we conceived and tested a new participatory method to map the distribution of three invasive species (Callinectes sapidus, Procambarus clarkii and Oreochromis niloticus) in the [...]
Insights from regional and short-term biodiversity monitoring datasets are valuable. A Reply to Daskalova et al. 2020 EcoEvoRxiv doi:10.32942/osf.io/cg3zs
Published: 2020-10-15
Subjects: Biodiversity, Biology, Entomology, Life Sciences, Research Methods in Life Sciences
Reports of major losses in biodiversity have stimulated an increasing interest in temporal population changes, particularly in insects, which had received little attention in the past. Existing long-term datasets are often limited to a small number of study sites, few points in time, a narrow range of land-use intensities and only some taxonomic groups, or they lack standardized sampling. While [...]
A fine balance: specialized questioning techniques and their use in conservation
Published: 2020-10-01
Subjects: Ecology and Evolutionary Biology, Environmental Studies, Life Sciences, Other Social and Behavioral Sciences, Research Methods in Life Sciences, Social and Behavioral Sciences
Conservationists measuring noncompliance with rules about the exploitation of natural resources often need to ask sensitive questions. However, respondents can introduce bias through distorting their answers to direct questions, due to social norms and/or the risk of legal sanctions. Specialized Questioning Techniques (SQTs) are often a more suitable approach to counteracting respondent bias, as [...]
Assessing Raspberry Shake and Boom sensors for recording African elephant acoustic vocalizations

Subjects: Animal Sciences, Ecology and Evolutionary Biology, Life Sciences, Other Animal Sciences, Other Ecology and Evolutionary Biology, Research Methods in Life Sciences
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 [...]
A Beginner’s Guide to Conducting Reproducible Research
Published: 2020-05-03
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 [...]
COVID-19 has led to a global increase in web searches for bats: a risk for conservation ?
Published: 2020-04-29
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Life Sciences, Other Social and Behavioral Sciences, Research Methods in Life Sciences, Social and Behavioral Sciences
SARS-CoV-2, the virus that caused COVID-19 pandemic, is genomically similar to a SARS-like beta-coronavirus found in Chinese rhinolophids. This evolutionary relationship impressed global media, which emphasized bats as key actors in the spillover during the pandemic outbreak. In this study we highlight qualitative and quantitative changes about bats in the media coverage, and Internet search [...]
[Final version available] Explainable Artificial Intelligence enhances the ecological interpretability of black-box species distribution models
Published: 2020-04-17
Subjects: Artificial Intelligence and Robotics, Biodiversity, Computer Sciences, Ecology and Evolutionary Biology, Life Sciences, Physical Sciences and Mathematics, Research Methods in Life Sciences, Terrestrial and Aquatic Ecology
Species distribution models (SDMs) are widely used in ecology, biogeography and conservation biology to estimate relationships between environmental variables and species occurrence data and make predictions of how their distributions vary in space and time. During the past two decades, the field has increasingly made use of machine learning approaches for constructing and validating SDMs. Model [...]
Measurement and analysis of interspecific spatial associations as a facet of biodiversity
Published: 2019-12-06
Subjects: Ecology and Evolutionary Biology, Life Sciences, Research Methods in Life Sciences, Terrestrial and Aquatic Ecology
Interspecific spatial associations (ISA), which include co-occurrences, segregations, or attractions among two or more species, can provide important insights into the spatial structuring of communities. However, ISA has primarily been examined in the context of understanding interspecific interactions, while other aspects of ISA, including its relations to other biodiversity facets and how it [...]
Experimenting with the past to improve environmental monitoring programs

Subjects: Agriculture, Biodiversity, Ecology and Evolutionary Biology, Environmental Monitoring, Environmental Sciences, Life Sciences, Physical Sciences and Mathematics, Research Methods in Life Sciences
Long-term monitoring programs are a fundamental part of both understanding system dynamics and informing management decisions. However, monitoring programs not always designed to consider statistical power, site selection, or the full costs and benefits of monitoring. Further, data from monitoring programs with different goals and protocols are now being combined for comparative analyses. Key [...]
The role of replication studies in ecology
Published: 2019-10-10
Subjects: Ecology and Evolutionary Biology, Life Sciences, Research Methods in Life Sciences
Recent large-scale projects in other disciplines have shown that results often fail to replicate when studies are repeated. The conditions contributing to this problem are also present in ecology but there have not been any equivalent replication projects. Here we examine ecologists’ understanding of and opinions about replication studies. When asked what percentage of ecological studies are [...]
Evidence synthesis for tackling research waste

Slicing: a sustainable approach to the analysis of long-term biobanks
Published: 2018-12-19
Subjects: Life Sciences, Research Methods in Life Sciences
The longitudinal study of populations is a core tool for understanding ecological and evolutionary processes. These studies typically collect samples over individual lifetimes and across multiple generations, building up a continuously growing biobank from which samples are then analysed in clusters over time in the laboratory. To ensure data are comparable among clusters we need to account for [...]
