The origin and evolution of shrews (Soricidae, Mammalia).
Proc Biol Sci
December 2024
Department of Zoology, University of Cambridge CB2 3EJ, UK.
Shrews are among the most speciose of mammalian clades, but their evolutionary history is poorly understood. Their fossil record is fragmentary and even the anatomy of living groups is not well documented. Here, we incorporate the oldest, most complete fossil shrew yet known into the first phylogenetic analysis of the group to include molecular, morphological and temporal data.

Morphological observations of their endocranial structures allow for outlining some of the early steps of the evolutionary history of the cetacean brain. The external features of the brain and associated sinuses of Raoellidae are so far only documented by the virtual reconstruction of the endocast based on specimens of the species Indohyus indirae.

Two characteristic features distinguishing the extinct species (among other characters present in one combination or another in extant species) are sparse, inconspicuous elytral pubescence and rectangular, sharp posterior pronotal angles. The new species, Nicobium necrocrator sp.

The benthic pennate diatom Nitzschia navis-varingica, known for producing domoic acid (DA) and its isomers, is widely distributed in the Western Pacific (WP) region. To investigate the genetic differentiation and gene flow patterns among the populations in the WP, the genetic diversity of 354 strains of N. navis-varingica was analysed using two nuclear-encoded rDNA loci: the large subunit rDNA (LSU rDNA) and the internal transcribed spacer 2 (ITS2).

Article Synopsis
- The text discusses a diverse family of macrofungi, primarily wood-decaying fungi, containing about 89 species across various climates and some that act as pathogens for forest trees.
- Phylogenetic analysis using genomic data revealed two major clades of genera within this family, with additional insights about their evolutionary timeline, indicating significant diversification events in the Early Cretaceous and Eocene epochs.
- The study also introduces a new species identified in Oman, detailing its morphological characteristics and genetic relationships, alongside an identification key and discussions on the ecology and distribution of the family’s species.
