The Hawaiian Islands represent one of the few ecosystems in the world that lacks native ants and thus represents a unique environment in which to study invasion biology. In the course of a study of behavioral interactions among invasive ant species, we collected the most abundant ants from four different field sites on the islands of Oahu and Hawaii. One year after the original collections, we ...

In this study, chromosome numbers of five Cardamine taxa [C. bulbifera Crantz, C. impatiens var. pectinata (Pall. ex DC.) Trautv., lazica Boiss. & Bal., tenera Gmel Mey. and graeca L.] from Turkey have been informed for the first time. The were determined as 2n=4x=24 in bulbifera, 2n=2x=16 tenera, 2n=2x=14 lazica, 2n=2x=12 graeca. Also, was different others with having satellite. Chromosomes st...

An estimate of phylogenetic relationships within Apiaceae subfamily Saniculoideae was inferred using data from the chloroplast DNA trnQ-trnK 5'-exon region to clarify the circumscription of the subfamily and to assess the monophyly of its constituent genera. Ninety-one accessions representing 14 genera and 82 species of Apiaceae were examined, including the genera Steganotaenia, Polemanniopsis,...
