The bumble bees (Hymenoptera: Apidae: Bombus) of Arkansas, fifty years later [PDF]
, 2015 Many species of bumble bees (Hymenoptera: Apidae: Bombus Latreille) are declining throughout their ranges in North America, yet detecting population trends can be difficult when historical survey data are lacking. In the present study, contemporary data

Phylogeny of Amorpheae (Fabaceae: Papilionoideae) [PDF]
American Journal of Botany, 2004 The legume tribe Amorpheae comprises eight genera and 240 species with variable floral form. In this study, we inferred a phylogeny for Amorpheae using DNA sequence data from the plastid trnK intron, including matK, and the nuclear ribosomal ITS1, 5.8S, and ITS2.

ChemMedChem, EarlyView.A series of 42 homoisoflavones were synthesized and evaluated against Mycobacterium tuberculosis (Mtb). Three derivatives showed potent inhibition of Mtb strains. Evaluation in infected macrophages revealed promising intracellular activity, where one derivative featuring a nitrofuranyl and piperidine group emerges as the most promising.

Impact of broom, Cytisus scoparius (Fabaceae), in naturally treeless sub-alpine frost-hollow vegetation communities at the Barrington Tops, south-eastern Australia [PDF]
, 2013 The exotic shrub Cytisus scoparius (L.) Link (family Fabaceae), known as broom, is having a major impact on native vegetation in naturally treeless sub-alpine frost-hollow areas (c. 32o 01’ 37” S, 151o 26’ 12” E’, 1440 m elevation) at the Barrington Tops,

Ecography, EarlyView.Delayed greening, the phenomenon in which expanding leaves appear red, blue or pale green due to low chlorophyll content, has long intrigued ecologists. However, little is known about what type of species are most likely to delay greening or which environmental conditions are associated with delayed greening.

INDEPENDENT ORIGINATION OF FLORAL ZYGOMORPHY, A PREDICTED ADAPTIVE RESPONSE TO POLLINATORS: DEVELOPMENTAL AND GENETIC MECHANISMS [PDF]
, 2016 Observations of floral development indicate that floral organ initiation in pentapetalous flowers more commonly results in a medially positioned abaxial petal (MAB) than in a medially positioned adaxial petal (MAD), where the medial plane is defined by ...

Ecography, EarlyView.Invasive alien plant species can cause considerable ecological, economic, and social impacts, and the number of impactful species will likely increase with globalisation and anthropogenic climate change. Preventing potentially invasive alien plant species from becoming introduced is the most cost‐effective way to protect Norway's ecosystems from future
