Pollen landscape saturation on pollinator bodies reduces pollen deposition by subsequently visited bat‐pollinated flowers

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Sexual selection in flowering plants often operates through male–male competition, yet the mechanisms underlying this phenomenon remain difficult to demonstrate. One potential arena for such competition is pollen placement on pollinators, where pollen grains from ...

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

Integrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Unravelling the phylogeny of armadillos and their kin (Mammalia, Xenarthra, Cingulata) combining morphological, molecular, and stratigraphic data

Cladistics, EarlyView.
Abstract Cingulata, a major lineage of Xenarthra, comprises extinct and extant armoured placental mammals that diversified throughout the Cenozoic. Despite extensive study, phylogenetic hypotheses based on morphological and molecular data remain incongruent, and no total evidence analysis has been conducted. Here, we integrate the largest morphological

Overexpression of MAP2 and NF-H Associated with Dendritic Pathology in the Spinal Cord of Mice Infected with Rabies Virus

Viruses, 2018
Rabies is a viral infection that targets the nervous system, specifically neurons. The clinical manifestations of the disease are dramatic and their outcome fatal; paradoxically, conventional histopathological descriptions reveal only subtle changes in ...

Cryptic diversity and recent diversification in the Pyrrhulina australis species complex (Characiformes, Lebiasinidae) revealed by mitochondrial DNA

Journal of Fish Biology, EarlyView.
Abstract Pyrrhulina australis Eigenmann & Kennedy, 1903, is widely distributed across the main hydrographic basins of South America. The taxonomic integrity of this species is nevertheless challenged by the lack of clear diagnostic characters, its marked geographic variation and the morphological overlap with its congeners. In this context, the present
