Image-based taxonomic classification of bulk biodiversity samples using deep learning and domain adaptation

Tomochika Fujisawa, Víctor Noguerales, Emmanouil Meramveliotakis, Anna Papadopoulou & Alfried Vogler
Complex bulk samples of invertebrates from biodiversity surveys present a great challenge for taxonomic identification, especially if obtained from unexplored ecosystems. High-throughput imaging combined with machine learning for rapid classification could overcome this bottleneck. Developing such procedures requires that taxonomic labels from an existing source data set are used for model training and prediction of an unknown target sample. Yet the feasibility of transfer learning for the classification of unknown samples remains to be tested....

The life and times of Pteridinium simplex

Simon Darroch, Brandt Gibson, Maggie Syversen, Imran Rahman, Rachel Racicot, Frances Dunn, Susana Gutarra-Diaz, Eberhard Schindler, Achim Wehrmann & Marc Laflamme
Pteridinium simplex is an iconic erniettomorph taxon best known from late Ediacaran successions in South Australia, Russia, and Namibia. Despite nearly 100 years of study, there remain fundamental questions surrounding the paleobiology and -ecology of this organism, including it’s life position relative the sediment-water interface, and how it fed and functioned within benthic communities. Here, we combine a re-description of specimens housed at the Senckenberg Forschungsinstitut und Naturmuseum Frankfurt with field observations of fossiliferous surfaces...

Data from: Community assembly and metaphylogeography of soil biodiversity: insights from haplotype-level community DNA metabarcoding within an oceanic island

Carmelo Andújar Fernández, Paula Arribas, Heriberto López, Yurena Arjona, Antonio José Pérez-Delgado, Pedro Oromí, Alfried P. Vogler & Brent C. Emerson
Most of our understanding of island diversity comes from the study of aboveground systems, while the patterns and processes of diversification and community assembly for belowground biotas remain poorly understood. Here we take advantage of a relatively young and dynamic oceanic island to advance our understanding of eco-evolutionary processes driving community assembly within soil mesofauna. Using whole organism community DNA (wocDNA) metabarcoding and the recently developed metaMATE pipeline, we have generated spatially explicit and reliable...

Individual repeatability of avian migration phenology: a systematic review and meta-analysis

Kirsty Franklin, Malcolm Nicoll, Simon Butler, Ken Norris, Norman Ratcliffe, Shinichi Nakagawa & Jennifer Gill
Changes in phenology and distribution are being widely reported for many migratory species in response to shifting environmental conditions. Understanding these changes and the situations in which they occur can be aided by understanding consistent individual differences in phenology and distribution and the situations in which consistency varies in strength or detectability. Studies tracking the same individuals over consecutive years are increasingly reporting migratory timings to be a repeatable trait, suggesting that flexible individual responses...
