Summary: This study analyzes the morphological variability of Caquetaia kraussii and finds that environmental stress influences about 10% of its body shape, while the majority of the variability is not directly influenced by environmental parameters, suggesting a possible effect from sexual dimorphism. Additionally, there is shape variation among populations of different localities, which may be subject to environmental and sexual stresses.

Summary: This study evaluated the effects of water-soluble 17 beta estradiol exposure on the external morphology of Bluegill, showing changes in male dimorphic characters and morphological structure. These changes could potentially impact reproductive success and mate selection in fish populations.

Summary: Manually collecting landmarks for complex morphological phenotypes can be tedious and prone to errors. We introduce a fast and open-source automated landmarking pipeline (MALPACA) that uses multiple templates to accommodate large-scale variations. Our results show that MALPACA outperforms single-template methods and we also provide a K-means method for template selection. MALPACA is an efficient and reproducible method that can handle large morphological variability.

Summary: The study suggests that using the shape of crab carapaces as a biomarker for the environmental quality of salt marsh systems, particularly for monitoring metal pollution, is an effective method. By applying geometric morphometrics, the research delves into symmetric and asymmetric variations in carapace shape, finding that the symmetric component can serve as a stress biomarker related to metal contamination.

Summary: From a taxonomic perspective, it is crucial to understand the differences in skull shape between species and breeds. This study identified variations in the shape of the skulls of three different cat breeds, with the orbit being the main differentiating factor. The shape of the orbit's edge has been shown to be a distinctive feature for distinguishing between cat skulls.

Summary: Postnatal growth in mammals is crucial for acquiring adult shape. The mandible undergoes changes in response to functional constraints, leading to bone formation and remodelling to accommodate dietary and behavioural changes. Interactions between bone, muscles, and teeth drive developmental plasticity, resulting in convergences in ontogenies and adult shape variations.

Summary: The accumulation of functional diversity in communities is investigated in a multiscale study of land snail communities on 10 oceanic archipelagos. Consistent patterns of functional diversity across island ontogeny on all examined archipelagos indicate a common role for habitat filtering, ecological opportunity, and competition in diverse systems, leading to predictable changes in functional diversity and average morphology through island ontogeny.

Summary: This study shows that the traditional naming conventions and classification methods for Cannabis may not be suitable for plants based on hybrid lineages. Therefore, a new system is needed to identify variations within Cannabis and provide reliable property identifiers.

Summary: The article discusses the application and advantages of geometric morphometrics in analyzing biogenic recording structures, with a focus on the potential of outline-based geometric morphometrics in structure identification. The differences between outline-based geometric morphometrics and traditional methods are highlighted.

Summary: This study aims to provide evidence for the morphological differentiation between subspecies and putative species in the South American river dolphins genus Inia. Results show that there is significant morphometric diversity within the group, inconsistent with the assumption of a single taxon. The traditional differentiation of three distinct morphotypes corresponding to described subspecies I. g. geoffrensis, I. g. humboldtiana, and I. g. boliviensis is supported by the morphometric evidence. Additionally, there are no differences in morphometric data between I. g. geoffrensis and the newly proposed species I. araguaiaensis. The conservation importance of the genus and the different threats they face suggests an urgent need for integrative taxonomic treatment to protect these unique cetaceans.

Summary: Placoderms, an extinct group of jawed vertebrates, are important for understanding the evolution of jawed animals. However, due to the poor preservation of their cartilaginous axial and fin elements, our knowledge of their anatomy and ecological adaptations is limited.

Summary: African mole-rats of the genus Fukomys exhibit a unique combination of monogamous mating system and sexual size dimorphism, living in cooperatively breeding groups. Male mole-rats have larger skulls relative to body size and expansion of the facial portion of the cranium, with no effect from reproductive status. Scaling analyses show compliance to Rensch's rule, indicating intense male intrasexual competition in Fukomys species.

Summary: This study on the seed beetle Acanthoscelides obtectus found that females were larger than males and had different modular organization, indicating that reproductive function plays a central role in forming patterns of modularity.

Summary: This study found sexual dimorphism in the wing form of the subgenus Avaritia, with differences in traits between species. Wing shape is optimized for different flight types in males and females, with shape differences being more pronounced in males and strongly associated with aspect ratio. It suggests that selective pressures affecting flight performance characteristics are more varied and intense in males than in females among the studied species.

Summary: This study investigated the morphological changes in the adult offspring of T. castaneum and T. confusum after exposure to two insecticides. Results showed that T. confusum had higher tolerance to the insecticides compared to T. castaneum. The hindwings of T. castaneum experienced deformations, with more significant changes observed in the alpha-cypermethrin treatment. The findings suggest that deformities caused by insecticide exposure in parental adults could reduce the frequency of insecticidal applications in storage facilities.
