Population genetics of Zamia decumbens (Zamiaceae, Cycadales), an endangered cycad from the Maya Mountains of Belize

open access: yesPlant Species Biology, EarlyView.
We utilized 10 microsatellite loci to examine the genetic diversity, genetic structure, and demographic history of Zamia decumbens Calonje, Meerman, M.P. Griff. & Hoese, an endangered cycad species occurring in small disjunct populations on karst topography within the Maya Mountains of Belize.

Integrative taxonomy of the Ceratozamia mexicana Brongn. (Zamiaceae) species complex from a phylogeographic perspective

open access: yesPlant Species Biology, EarlyView.
Recent research has ignited a renewed interest in Ceratozamia cycads, unveiling their remarkable diversity. While previous studies primarily focused on morphology, this investigation employs a multidisciplinary approach, integrating phylogenetics, morphology, and ecological niches. Our methods identify seven distinct lineages as separate species.

Infectious diseases, imposing density-dependent mortality on MHC/HLA variation, can account for balancing selection and MHC/HLA polymorphism [PDF]

open access: yesarXiv
The human MHC transplantation loci (HLA-A, -B, -C, -DPB1, -DQB1, -DRB1) are the most polymorphic in the human genome. It is generally accepted this polymorphism reflects a role in presenting pathogen-derived peptide to the adaptive immune system.

Multilocus sequence typing of the invasive pest Halyomorpha halys (Hemiptera: Pentatomidae) and associated endosymbiont reveals unexplored diversity

open access: yesInsect Science, EarlyView.
A multilocus sequence typing approach is proposed to explore Halymorpha halys genetic diversity, taking into consideration both insect nuclear markers and markers from the gut symbiont “Candidatus Pantoa carbekii.” Increased information was revealed regarding the number of distinct holobiont haplotypes in native and invasive populations of the pest ...
