Rules of Plant Species Ranges: Applications for Conservation Strategies

open access: yesFrontiers in Ecology and Evolution, 2021
Earth is changing rapidly and so are many plant species’ ranges. Here, we synthesize eco-evolutionary patterns found in plant range studies and how knowledge of species ranges can inform our understanding of species conservation in the face of global ...

Genetic diversity and population structure of endangered rosewood from the Peruvian Amazon using ISSR markers [PDF]

open access: yesActa Amazonica, 2020
Rosewood, Aniba rosaeodora is an endangered species in Amazon forests and its natural stands have been heavily depleted due to over-exploitation for the cosmetic industry.

Gene Flow Between Great Lakes Region Populations of the Canadian Tiger Swallowtail Butterfly, \u3ci\u3ePapilio Canadensis\u3c/i\u3e, Near the Hybrid Zone With \u3ci\u3eP. Glaucus\u3c/i\u3e (Lepidoptera: Papilionidae) [PDF]

open access: yes, 2018
Papilio canadensis were sampled from three locations on either side of Lake Michigan to study gene flow near and through a butterfly hybrid zone. Allele frequencies at four polymorphic enzyme loci, as indicated by allozyme electrophoresis, were similar ...

Rivers of Gene Flow [PDF]

open access: yesScience, 2012
Ecology![Figure][1] CREDIT: © PETE MCBRIDE/NATIONAL GEOGRAPHIC SOCIETY/CORBIS Antibiotic resistance is becoming an urgent problem. We point one finger at lax medication sales, and another at livestock husbandry, but there is also an ancient background signal of antibiotic resistance, in part stemming from the natural functions of these molecules in ...

Defining Species When There is Gene Flow [PDF]

open access: yesSystematic Biology, 2020
AbstractWhatever one’s definition of species, it is generally expected that individuals of the same species should be genetically more similar to each other than they are to individuals of another species. Here, we show that in the presence of cross-species gene flow, this expectation may be incorrect.

Insights into PI3K/AKT signaling in B cell development and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
This Review explores how the phosphoinositide 3‐kinase and protein kinase B pathway shapes B cell development and drives chronic lymphocytic leukemia, a common blood cancer. It examines how signaling levels affect disease progression, addresses treatment challenges, and introduces novel experimental strategies to improve therapies and patient outcomes.

Potential for gene-flow from cultivated Irish grasses and cereals [PDF]

open access: yes, 2009
End of project reportThe importance of gene movement from cultivated plants has been highlighted in regard to minimising the movement of seed and/or pollen between GM and non-GM crops (i.e. gene flow). Although ryegrass covers in excess of 90% of Ireland’

Population genetics models of local ancestry

open access: yes, 2012
Migrations have played an important role in shaping the genetic diversity of human populations. Understanding genomic data thus requires careful modeling of historical gene flow.

The Himalayas as a Directional Barrier to Gene Flow [PDF]

open access: yesThe American Journal of Human Genetics, 2007
High-resolution Y-chromosome haplogroup analyses coupled with Y-short tandem repeat (STR) haplotypes were used to (1) investigate the genetic affinities of three populations from Nepal--including Newar, Tamang, and people from cosmopolitan Kathmandu (referred to as "Kathmandu" subsequently)--as well as a collection from Tibet and (2) evaluate whether ...
