  • The Nordic collections are used today primarily to clarify which species have been present at a certain place at a certain time, for example, to be able to study how changes in the environment and climate have affected the flora over the past 200 years and to document newly immigrated potentially invasive species.

  • In the context of a family-level phylogeny, we can trace the evolution of the leiognathid LOS from a 'simple' non-sexually dimorphic circumesophageal light organ to a complex and species-specific luminescence system involving not only major structural modifications of the light organ itself but also numerous associated tissues.

  • Jessica Pamment, professional lecturer at DePaul University, walks through the evolution of species and their relationships to other groups. (coursehero.com)
  • A phylogeny illustrates the evolution of species and their relationships to other groups. (coursehero.com)
  • If that new trait is inherited, this may ultimately result in the evolution of one or more species. (coursehero.com)
  • A common ancestor may refer to an earlier organism that, through evolution, gives rise to new species that are related. (coursehero.com)
  • Lastly, I combine trait and phylogenetic information to explore patterns of trait evolution and determine how species that specialize in different environments are distributed across the phylogeny. (ubc.ca)

  • The results show that the similarity between different animal species in the middle of their embryonic development is shaped by selection,' adds Casey Bergmann, a co-author from the University of Manchester. (news-medical.net)
  • Our results indicate that species of conservation concern (IUCN ranking near threatened or above) are more likely to have a specialized diet than are species of least concern. (googleapis.com)
  • Our results may have important implications for the development of predictive models of extinction risk and for the assignment of extinction risk to insectivorous bat species. (googleapis.com)
  • However, not all phylogenies are trees: hybridization can occur and create new species and this results into reticulate phylogenies. (biomedcentral.com)
  • Cladistic analysis of the A-199a sequences was performed using Wagner parsimony to construct a soybean phylogeny. (nau.edu)
  • Based on significant vocal and phylogenetic differences, in July 2022 the South American Classification Committee of the American Ornithological Society split L. c. velutina and L. c. minuscula from L. coronata and named the resulting L. velutina the velvety manakin. (wikipedia.org)
  • The astonishing similarity in the appearance of embryos from different animal species was observed as far back as the 19th century by scientists such as Karl von Baer, Charles Darwin and Ernst Haeckel. (news-medical.net)
