Tell Me How Much DNA You Have and I'll Tell You What Your Sex Is: Sex Determination by Flow Cytometry of Spiderlings of Allocosa marindia [PDF]
Ecology and Evolution, Volume 16, Issue 4, April 2026.The manuscript addresses the sex determination of spiderlings of the wolf spider Allocosa marindia using flow cytometry. Spiders are born with a defined sex, but it is not possible to determine their sex phenotypically until the adult or near‐adult stage. Sex identification at early stages of development is of great interest for studies in evolutionary

Sex‐Specific Variation in Foraging Behavior is Related to Telomere Length in a Long‐Lived Seabird [PDF]
Ecology and Evolution, Volume 14, Issue 12, December 2024.Foraging during breeding is energetically demanding, intimately linked to breeding investment, and possibly constrained by individual condition. Telomere length, the protective nucleoproteins located at the ends of the chromosomes, is considered a trait reflecting somatic maintenance and individual quality. We found that brown booby females with longer

Meristic co‐evolution and genomic co‐localization of lateral line scales and vertebrae in Central American cichlid fishes [PDF]
Ecology and Evolution, Volume 14, Issue 9, September 2024.We dissect the co‐evolution and genetic architecture of lateral line scale counts and vertebrae numbers in Neotropical Heroine cichlids. Our phylogenetic comparative analyses recovered a positive correlation between these two traits. Furthermore, our qualitative traits locus (QTL) analyses identified significant genomic co‐localized associations for ...

New approaches to studying early brain development in Down syndrome
Developmental Medicine &Child Neurology, Volume 61, Issue 8, Page 867-879, August 2019., 2019 Down syndrome is the most common genetic developmental disorder in humans and is caused by partial or complete triplication of human chromosome 21 (trisomy 21). It is a complex condition which results in multiple lifelong health problems, including varying degrees of intellectual disability and delays in speech, memory, and learning. As both length and

Physical Mapping of Bread Wheat Chromosome 5A: An Integrated Approach
The Plant Genome, Volume 8, Issue 3, November 2015., 2015 The huge size, redundancy, and highly repetitive nature of the bread wheat [Triticum aestivum (L.)] genome, makes it among the most difficult species to be sequenced. To overcome these limitations, a strategy based on the separation of individual chromosomes or chromosome arms and the subsequent production of physical maps was established within the ...

Urban Studies Research, Volume 2011, Issue 1, 2011., 2011 This paper analyzes the governance strategy of the 22@ District in Barcelona in order to assess the factors that explain its success and could support the economic reconversion of Montreal’s future Innovation District (ID), as well as that of other cities. We examine the case of the 22@ District as a former industrial neighbourhood seen as a “model” of
