Stronger effect of temperature on body growth in cool than in warm populations suggests lack of local adaptation

open access: yesEcography, EarlyView.
Body size is a key functional trait that has declined in many biological communities, partly due to changes in individual growth rates in response to climate warming. However, our understanding of growth responses in natural populations is limited by relatively short time series without large temperature contrasts and unknown levels of adaptation to ...

Efficient Curation of Invertebrate Image Datasets Using Feature Embeddings and Automatic Size Comparison [PDF]

open access: yesarXiv
The amount of image datasets collected for environmental monitoring purposes has increased in the past years as computer vision assisted methods have gained interest. Computer vision applications rely on high-quality datasets, making data curation important. However, data curation is often done ad-hoc and the methods used are rarely published.

Global phylogenetic and functional structure of rodent assemblages

open access: yesEcography, EarlyView.
Exploring the global patterns of phylogenetic and functional structure of assemblages is key to describe the distribution of biodiversity on Earth and to predict how communities and ecosystem functioning may be affected by anthropogenic pressures. Rodent communities have been studied in this regard in the past, but previous work largely focused on ...

Letter to Jane Claire Dirks Acknowledging Smithsonian Specimen Contributions [PDF]

open access: yes, 1941
Many of the specimens collected by Jane Claire Dirks (later Jane Claire Dirks-Edmunds) went on to become part of her colleagues\u27 collections. In this letter, Paul Bartsch, Curator of the the Divisions of Mollusks and Cenozoic Invertebrates at the ...

SuoiAI: Building a Dataset for Aquatic Invertebrates in Vietnam [PDF]

open access: yesarXiv
Understanding and monitoring aquatic biodiversity is critical for ecological health and conservation efforts. This paper proposes SuoiAI, an end-to-end pipeline for building a dataset of aquatic invertebrates in Vietnam and employing machine learning (ML) techniques for species classification. We outline the methods for data collection, annotation, and

Habitat heterogeneity overrides local processes to drive the species–area relationship of benthic macroinvertebrates in shallow floodplain lakes

open access: yesEcography, EarlyView.
The species–area relationship (SAR) on islands describes how the numbers of species increase with increasing island size (or island‐like habitat, such as lakes). Despite its conceptual importance, there is considerable uncertainty surrounding its shape in freshwater lakes, as well as the potential mechanisms that underlie the SAR.

METHOD FOR MODULATING EICOSANOID MEDIATED IMMUNE RESPONSES IN ARTHROPODS [PDF]

open access: yes, 2000
The invention is directed to compositions which alter the health of invertebrate organisms by affecting eicosanoid mediated immune responses, and methods of using the compositions.

The effects of climate on bat morphology across space and time

open access: yesEcography, EarlyView.
According to Bergmann's and Allen's rules, climate change may drive morphological shifts in species, affecting body size and appendage length. These rules predict that species in colder climates tend to be larger and have shorter appendages to improve thermoregulation. Bats are thought to be sensitive to climate and are therefore expected to respond to
