Article Abstract
Premise: Plant morphological traits, their observable characteristics, are fundamental to understanding the role played by each species within its ecosystem; however, compiling trait information for even a moderate number of species is a demanding task that may take experts years to accomplish. At the same time, online species descriptions contain massive amounts of information about morphological traits, but the lack of structure makes this source of data impossible to use at scale.
Methods: To overcome this, we propose to leverage recent advances in large language models and devise a mechanism for gathering and processing plant trait information in the form of unstructured textual descriptions, without manual curation.
Results: We evaluate our approach by automatically replicating three manually created species-trait matrices. Our method found values for over half of all species-trait pairs, with an F1 score of over 75%.
Discussion: Our results suggest that large-scale creation of structured trait databases from unstructured online text is now feasible due to the information extraction capabilities of large language models. However, the process is currently limited by the availability of textual descriptions that cover all traits of interest.

Background And Aims: Trait-based approaches have advanced our understanding of plant strategies, yet they often focus on leaf-level traits, overlooking the functional roles of stem anatomy and twig characteristics. We investigated intraspecific trait variation in Salix flabellaris, an alpine dwarf shrub, along climatic gradients in the Himalayas. Our goal was to identify distinct axes of trait variation related to stem, twig, and leaf traits, assess their environmental drivers, and evaluate population-specific growth responses to recent climate change.

(Linnaeus, 1767), a member of the Blattellidae family within the order Blattodea, is a significant global sanitary pest. Several species within the genus Caudell, 1903 and its closely related genera ( Bey-Bienko, 1950; Hebard, 1916; and Hebard, 1929) exhibit external morphological traits similar to those of . By integrating morphological identification and molecular analyses, one new species was identified: Cai, Yao & Che, Additionally, Mizukubo, 1981 was downgraded to a subspecies of .

Understanding the relationship between macro- and microevolutionary processes and their delimitation remains a challenge. This review focuses on the role of chromosomal rearrangements in plant population differentiation and lineage diversification resulting in speciation, helping bridge the gap between macro- and microevolution through chromosomal evolution. We focus on angiosperms, a group that comprises the majority of extant plant species diversity and exhibits the largest chromosomal and genomic variations.

Camels have unique morphological traits that enable them to adapt well to harsh conditions. This work aims to describe the vascular architecture of the camel retina and investigate its cellular components with a focus on the distribution of mitochondria in Muller cells and photoreceptors, using light and electron microscopy. The camel retina is euangiotic in which blood vessels extend in the inner retina from the nerve fiber layer to the outer plexiform layer.

Echinorhynchids are a group of globally distributed acanthocephalan parasites mainly of freshwater, brackish and marine fishes and occasionally, reptiles and amphibians. During several parasitology surveys in the Gulf of Mexico and Northeast Pacific, Mexico, acanthocephalans were recovered from two marine fish species. The specimens from the Gulf of Mexico were identified as Caballerorhynchus lamothei (Cavisomidae), a typical parasite of the striped mojarra, whereas adult acanthocephalans from the Northeast Pacific, Mexico, from the Garibaldi fish exhibited morphological characteristics belonging to the family Transvenidae.
