Phylogeny and historical biogeography of the Pachira sensu lato clade (Bombacoideae, Malvaceae) with a new infrageneric classification

open access: yesTAXON, EarlyView.
Abstract We explore phylogenetic relationships within the Pachira sensu lato clade (Bombacoideae, Malvaceae), test the monophyly of the genera Eriotheca and Pachira, and investigate their biogeographic history. The Pachira s.l. clade comprises ca. 72 species that traditionally have been placed in Eriotheca and Pachira. We sampled ca. 79% of its species

Rubidium marking of Aphidius rhopalosiphi (Hymenoptera: Braconidae) on Sitobion avenae (Hemiptera: Aphididae) reared on a diet supplemented with RbCl

open access: yesEuropean Journal of Entomology, 2005
Markers are essential to study movements of insects in their natural habitat. Among the available techniques, trace elements may be applied to insects as small as parasitoids. Rubidium is the most common element used for marking insects.

Characterization of the Carbonyl Metalates [Mn2(CO)8]2− and [W2(CO)8]4− Featuring M=M Double Bonds

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The novel homoleptic carbonyl metalate anions [Mn2(CO)8]2− and [W2(CO)8]4− featuring M=M double bonds are structurally characterized and investigated using quantum chemical calculations and QTAIM methods. The crystal structures of [Rb[2.2.2]crypt]2[Mn2(CO)8] ⋅ 4NH3 and [K[18]crown‐6]2K2[W2(CO)8] ⋅ 14NH3 are reported, containing the first homoleptic ...

DNA Barcoding the Canadian Arctic Flora: Core Plastid Barcodes (rbcL + matK) for 490 Vascular Plant Species

open access: yesPLoS ONE, 2013
Accurate identification of Arctic plant species is critical for understanding potential climate-induced changes in their diversity and distributions. To facilitate rapid identification we generated DNA barcodes for the core plastid barcode loci (rbcL and

Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)

open access: yesInsect Science, EarlyView.
As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...
