Developmental Dynamics, EarlyView.Abstract Homology in vertebrate body plans is traditionally ascribed to the high‐level conservation of regulatory components within the genetic programs governing them, particularly during the “phylotypic stage.” However, advancements in embryology and molecular phylogeny have unveiled the dynamic nature of gene repertoires responsible for early ...

Limb preference in the gallop of dogs and the half-bound of pikas on flat ground [PDF]
Laterality 13, 4 (2008) 310-319, 2008 During fast locomotion - gallop, half bound - of quadruped mammals, the ground contact of the limbs in each pair do not alternate symmetrically. Animals using such asymmetrical gait thus choose whether the left or the right limb will contact the ground first, and this gives rise to limb preference.

Wallacean mammalogy and zooarchaeology: remembrances and a renaissance
Records of the Australian Museum, 2023 [Excerpt] The richness of life is not distributed haphazardly across the globe, but instead exhibits profound, non-random patterns. Numbers of species of insects, trees, and frogs, for example, abound in tropical localities, like in Brazil or the Congo ...

Fast Compatibility Testing for Phylogenies with Nested Taxa [PDF]
arXiv, 2016 Semi-labeled trees are phylogenies whose internal nodes may be labeled by higher-order taxa. Thus, a leaf labeled Mus musculus could nest within a subtree whose root node is labeled Rodentia, which itself could nest within a subtree whose root is labeled Mammalia.

Aminoisothiazolamides, a new class of potent inhibitors of lysyl‐tRNA synthetase
Pest Management Science, EarlyView.The present work covers a series of novel herbicidal lead structures that possess an aminoisothiazolamide scaffold as a structural key feature. Lysyl‐tRNA synthetase 1 (KRS1) was identified as the biochemical mode‐of‐action. Based on optimized and tailored synthetic approaches, a broader SAR study was carried out delivering some lead structures that ...

Reconstruction of the deep history of "Parent-Daughter" relationships among vertebrate paralogs [PDF]
arXiv, 2018 Gene duplication is a major mechanism through which new genetic material is generated. Although numerous methods have been developed to differentiate the ortholog and paralogs, very few differentiate the "Parent-Daughter" relationship among paralogous pairs.

Integrative Zoology, EarlyView.Our findings reveal that the western black crested gibbon (Nomascus concolor) did not divide into different subspecies, and the relatively low level of genetic diversity emphasizes the importance of monitoring this indicator for vulnerable wildlife.

Neotropical IchthyologyThe fossil species Arrhinolemur scalabrinii, which was described from late Miocene deposits of Entre Ríos, Argentina, is reevaluated. Whereas the species was originally placed in the Primates (Mammalia) and later made the unique member of the order ...

A Comprehensive Evaluation of Taxonomic Classifiers in Marine Vertebrate eDNA Studies
Molecular Ecology Resources, EarlyView.ABSTRACT Environmental DNA (eDNA) metabarcoding is a widely used tool for surveying marine vertebrate biodiversity. To this end, many computational tools have been released and a plethora of bioinformatic approaches are used for eDNA‐based community composition analysis.

Cladistics, EarlyView.Abstract Using a new character matrix composed of revised matrices of previous analyses and new morphological findings, the phylogeny of Malacostraca (Pancrustacea) is analysed anew with 207 characters for 35 terminal taxa across all recognized orders. Particular emphasis was placed on methodological versatility, including different degrees of implied ...
