Little parallelism in genomic signatures of local adaptation in two sympatric, cryptic sister species

Journal of Evolutionary Biology, Volume 34, Issue 6, Page 937-952, June 2021., 2021
A whole‐genome analysis of two cryptic, sympatric sister species of the neotropical ant Crematogaster levior sampled along a climatic gradient in French Guiana was carried out. The correlations between population‐specific environmental parameters and cuticular hydrocarbon profiles reveal very little parallelism in genomic signatures of selection ...

Multiple Upper Outlier Detection Procedure in Generalized Exponential Sample

European Journal of Statistics, 2021
Hawkins [6] defined an outlier as an observation that is significantly different from the remaining observations in a dataset so as to arouse suspicion that it was generated by different mechanism.

Cuticular hydrocarbons as potential mediators of cryptic species divergence in a mutualistic ant association

Ecology and Evolution, Volume 9, Issue 16, Page 9160-9176, August 2019., 2019
The two mutualistically associated ant species Crematogaster levior and Camponotus femoratus from the neotropics both exhibit unusually high cuticular hydrocarbon (CHC) diversity. By analyzing genetic barcodes, cuticular hydrocarbon profile, and morphological data, we can conclusively show that this diversity in fact reflects cryptic species and argue ...

Poneromorph Ants Associated with Parasitoid Wasps of the Genus Kapala Cameron (Hymenoptera: Eucharitidae) in French Guiana

Psyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012
Eucharitid wasps are specific, specialized parasitoids of ants. The genus Kapala Cameron is the most common in the Neotropics but few species are described, and information dealing with their biology, behavior and host associations is scarce. Numerous poneromorph ant colonies were inspected over 4 collection surveys in French Guiana. A diverse fauna of
