Resolving taxa in a challenging orchid species complex using evidence from phylogenetics, morphometrics and floral scent chemistry

open access: yesTAXON, EarlyView.
Abstract Species can be difficult to circumscribe using morphology alone, and additional data can thus be useful for resolving challenging species complexes. Here we provide a case study of a South African orchid species complex which we resolved by analysing morphology, floral scent chemistry and molecular data.

More than fruity scents: Pollination biology, scent, and spectral reflectance of Annonaceae species

open access: yesPlant Species Biology, EarlyView.
We characterised the floral visual and olfactory cues of numerous Annonaceae species and reported their pollinators. We further assessed the olfactory space of most Annonaceae species available in the literature. Abstract The family Annonaceae possesses a broad array of floral phenotypes and pollination specializations, and are important in the plant ...

Evidence for transient deleterious thermal acclimation in field recapture rates of an invasive tropical species, Bactrocera dorsalis (Diptera: Tephritidae)

open access: yesInsect Science, EarlyView.
Abstract Knowing how environmental conditions affect performance traits in pest insects is important to improve pest management strategies. It can be informative for monitoring, but also for control programs where insects are mass‐reared, and field‐released.

Contact Urticaria and Related Conditions: Clinical Review

open access: yesContact Dermatitis, EarlyView.
ABSTRACT Contact urticaria (CoU) is an immediate contact reaction occurring within minutes to an hour after exposure to specific proteins or chemicals. CoU is categorised into non‐immunologic (NI‐CoU) and immunologic (I‐CoU) types, with I‐CoU potentially leading to anaphylaxis. Both forms of CoU can be associated with protein contact dermatitis and the
