Summary: The study found that in Norway, non-native plant species and native plant species have similar levels of herbivory, suggesting that enemy release does not facilitate the growth of non-native plants. However, lower levels of herbivory at higher latitudes indicate that herbivory may increase as the climate warms.

Summary: This study found that the recent severe damage to Japanese orchids is likely not due to the introduction of exotic species, but rather may be related to a rapid increase in a native species. By examining herbarium specimens, researchers were able to identify the fly species that could be causing the damage, highlighting the importance of herbaria in elucidating the history and distribution of parasitic insects.

Summary: Quantifying variation in susceptibility to insect herbivory among closely related plant species is important for understanding the evolutionary pressures on plant functional traits. However, it is logistically difficult to measure this variation in situ across the geographic range of a plant-insect complex. Recently, new methods using herbarium specimens have been developed to investigate patterns in plant-insect symbioses on a large scale, providing insights into how anthropogenic changes may impact these interactions.

Summary: Herbarium specimens are crucial for studying plant morphology and distribution. Digitised specimens have the potential to address broader research issues. A study developed an accurate image recognition system for identifying taxon names, which can be applied globally and help correct misidentified herbarium specimens.

Summary: Trace fossils of insect herbivory are an important tool for palaeoecological and palaeoclimatic interpretations. The La Val fossil site in the Iberian Peninsula provides evidence of numerous plant-insect interactions, with a decrease in diversity of interactions over time possibly due to changes in temperature or humidity levels.

Summary: With the increasing availability of digitized herbarium specimens in online repositories, the development of automated tools to process and enrich these collections has become crucial for better access to preserved archives. The automatic enrichment of multi-specimen herbaria sheets presents unique challenges, but in this study, experiments were conducted to identify effective models for plant specimen localization. The lack of labeled data was addressed by proposing tools and algorithms to semi-automatically generate annotations for herbarium images. The results showed that segmentation models performed better than detection models, achieving an F1 score of 0.977 for accurately extracting specimens from the background.

Summary: The passage presents the first evidence of plant-insect interactions from an ephemeral volcanic island, focusing mainly on interactions in leaves of Cycadophytes. These interactions have been categorized into different Damage Types and Functional Feeding Groups, suggesting colonization by various insect groups.

Summary: This study examined the effect of aboveground herbivory on mycorrhiza-dependent nitrogen uptake in maize. The results showed that aboveground leaf herbivory did not affect nitrogen acquisition from soil via extraradical mycorrhizal mycelium, but it blocked nitrogen transfer from neighboring plants through common mycorrhizal networks (CMNs).

Summary: Specimen records are an important source of species information for biodiversity research, but the currently available records may be biased in terms of geography and environment. This study focuses on geographical and environmental biases in online records of the flora of the Colombian Andes and finds significant sampling bias. The sampling is better in highland areas (>2000m) and poorer in mid- and lowland areas (e.g. montane and lowland forests). The median sampling completeness across the Colombian Andes is less than 75% at the scales studied.

Summary: In this study, the researchers analyzed the early defense responses of potato leaves to potato tuber moth (PTM) herbivory. They found that simulated and actual herbivory triggered similar hormonal and transcriptional responses in the plants. Microbes associated with PTM herbivory were found to regulate the phytohormones jasmonic acid (JA) and abscisic acid (ABA). Additionally, seven gene modules were identified to explain how potato plants respond to different PTM herbivory stimuli.

Summary: Honduras is one of the least studies countries in Central America in terms of botany. The scientific botanical information for Honduras is mostly found in global herbaria, which is often overlooked. This study aims to compile a comprehensive inventory of fern and lycopod records from international herbaria and identify biases in spatial, temporal, and collector distribution. The database generated from this study will support the protection and sustainable use of Honduran ecosystems.

Summary: A new universal independent data analysis pipeline based on Dynamic Analysis has been developed for processing X-ray Fluorescence (XRF) data of herbarium specimens. The pipeline is more accurate and robust than the built-in instrument algorithms and empirical calibrations, capable of correcting complex X-ray interactions and identifying and quantifying elements that are not detected by the device algorithms.

Summary: By annotating specimen images and cropping annotations using open-source software and a custom script, a training library for image classification can be generated quickly. The approach demonstrated in this research allows taxonomists to use digitized herbarium specimens to produce training libraries within hours. It is expected that computer vision will increasingly become a part of taxonomic practice.

Summary: Despite decades of research on epicuticular wax metabolism in plants, the role of these metabolites in plant-herbivore interactions remains unclear. This study found that knockout mutations in wax metabolism genes of Nicotiana glauca led to changes in wax composition, affecting interactions with insects and snails. Different herbivore classes and species showed varied responses to wax components, suggesting the specific effects of different surface wax components are shaped by co-evolution.

Summary: The objective of this study was to optimize a DNA extraction protocol for obtaining high-quality DNA from preserved herbarium tissue. The improved protocol yielded DNA comparable in quality to commercially available kits and suitable for other applications. This simple and fast method utilizes standard laboratory-grade chemicals.
