  • 1989 - Fellow of the American Association for the Advancement of Science (AAAS)

Overview

Katherine Ralls is affiliated with the Smithsonian Conservation Biology Institute in the United States. Their research spans multiple fields with a focus on biochemistry, genetics, molecular biology, and environmental science. Within these domains, their work particularly addresses genetics, ecology, ecology evolution, behavior and systematics, ecological modeling, and global and planetary change.

The scientist has made contributions to understanding genetic and phenotypic traits in livestock, genetic diversity and population structure, marine animal studies, wildlife ecology and conservation, genetic mapping and diversity in plants and animals, environmental DNA in biodiversity studies, and species distribution in relation to climate change.

Selected recent publications include:

  • Genetic rescue: A critique of the evidence supports maximizing genetic diversity rather than minimizing the introduction of putatively harmful genetic variation (2020, Biological Conservation)
  • A pragmatic approach for integrating molecular tools into biodiversity conservation (2023, Conservation Science and Practice)
  • Hunting cetaceans with sound: a worldwide review (2023, The journal of cetacean research and management. Special issue)
  • An efficient method for simultaneous species, individual, and sex identification via in-solution single nucleotide polymorphism capture from low-quality scat samples (2021, Molecular Ecology Resources)
  • U.S. Pacific Marine Mammal Stock Assessments: 2019 (2020, Lincoln (University of Nebraska))

Frequent co-authors include:

  • Brian L. Cypher
  • Paul Sunnucks
  • Robert C. Lacy
  • Richard Frankham
  • Robert L. Brownell

The scientist's work is often published in venues such as Biological Conservation, Conservation Science and Practice, the journal of cetacean research and management (special issue), Molecular Ecology Resources, and Lincoln (University of Nebraska).

Katherine Ralls was named a Fellow of the American Association for the Advancement of Science (AAAS) in 1989.
