Using citizen science photos to perform phenological studies

Post provided by Yves P. Klinger (he/him)

Photos collected by citizen scientists are a rich source of information that is still relatively unexplored. Phenology, the study of recurring biological events, could make use of photos taken by citizen scientists at different times, but accessing and preparing the plethora of publicly available data is challenging. In this post, Yves P. Klinger describes the motivation behind developing a workflow for using citizen science photos for phenological research, as featured in the paper “iPhenology – using open-access citizen science photos to track phenology at continental scale”.

plantR: Managing species records from biological collections

Post provided by Renato Lima

Many biodiversity studies, covering a wide range of goals, need species records. These records are becoming readily available online, however there is minimal standardisation for these records at this stage, therefore requiring final users to spend a significant amount of time formatting records prior to using data. To overcome this, Renato Lima et al. have created plantR – an open-source package that provides a comprehensive toolbox to manage species records from biological collections. In this blog post, Renato discusses the workflow of the package and describes how this package can help researchers better assess data quality and avoid data leakage.

Flora Incognita – more than just a plant identification app

Post provided by Michael Rzanny & Jana Wäldchen

Species identification is an essential tool for recording biodiversity, especially in an era of habitat loss and climate change. Developing skills to correctly identify plants to a species or even a genus level can take many years of training, but a new app called Flora Incognita aims to empower citizens with botanical expertise while also collecting data for scientific analysis.

In this blog post, Michael Rzanny and Jana Wäldchen reveal the inspiration behind this new app and discuss highlights from their new paper “The Flora Incognita app – interactive plant species identification” recently published in Methods in Ecology & Evolution.

Editor Recommendation: Quantitative Evolutionary Patterns in Bipartite Networks

Post provided by ROB FRECKLETON

The study of interactions and their impacts on communities is a fundamental part of ecology. Much work has been done on measuring the interactions between species and their impacts on relative abundances of species. Progress has been made in understanding of the interactions at the ecological level, but we know that co-evolution is important in shaping the structure of communities in terms of the species that live there and their characteristics.

Exploring Coevolutionary History: Do Entire Communities Shape the Evolution of Individual Species?

Post provided by Laura Russo, Katriona Shea, and Adam Miller

Diffuse Coevolution

Interactions between plants and pollinators tend to be highly generalized.
Interactions between plants and pollinators tend to be highly generalized.

In 1980, Janzen published an article titled “When is it coevolution?” where he explained the concept of diffuse coevolution: the idea that evolution of interacting species is shaped by entire communities, rather than simple paired interactions. This idea, though compelling, remains poorly understood, and strong evidence of diffuse coevolution acting on a community is lacking. Perhaps this is because there’s a lack of consensus on what would constitute evidence in support of the concept of diffuse coevolution, or, indeed, coevolution in general (Nuismer et al 2010).

Improved and Harmless Demethylation Method for Ecological Epigenetic Experiments

In a new Methods in Ecology and Evolution video, Javier Puy outlines a new method of experimental plant DNA demethylation for ecological epigenetic experiments. While the traditionally-used approach causes underdeveloped root systems and high mortality of treated plants, this new one overcomes the unwanted effects while maintaining the demethylation efficiency. The authors demonstrate its application for ecological epigenetic experiments: testing transgenerational effects of plant–plant competition. … Continue reading Improved and Harmless Demethylation Method for Ecological Epigenetic Experiments

Tiny Grains, Big Data: The Global Pollen Project

The Global Pollen Project is a new, online, freely available tool developed to help people identify and disseminate palynological resources. Palynology – the study of pollen grains and other spores – is used across many fields of study modern and fossil vegetation dynamics, forensic sciences, pollination, beekeeping, and much more. This platform helps to facilitate cross/multi-disciplinary integration and discussion, outsourcing identifications, expertise and the sharing of knowledge.

Pollen’s Role in Plant Conservation

Successful conservation of rare, threatened, and valuable plants is dependent on an understanding of the threats that they face. Also, conservationists must prioritise species and populations based on their value to humans, which may be cultural, economic, medicinal, etc. The study of fossil pollen (palaeoecology), deposited through time in sediments from lakes and bogs, can help inform the debate over which species to prioritise: which are native, and when did they arrive? How did humans impact species richness? By establishing such biodiversity baselines, policymakers can make more informed value judgements over which habitats and species to conserve, especially where conservation efforts are weighted in favour of native and/or endemic flora.
