Counter‐Stigmatization in the Digital Age: The Case of the Sex Tech Award Incident

open access: yesJournal of Management Studies, EarlyView.
Abstract Scholars have shown considerable interest in how organizations manage stigma when powerful actors discredit them and their products. However, research has paid less attention to how organizations might deflect stigma back onto their stigmatizers.

Larvicidal potential of Cyathea species against Culex quinquefasciatus

open access: yesPharmaceutical and Biomedical Research, 2017
Resistance to insecticides has persuaded researchers to find new methods to control Culex quinquefasciatus proliferation. Plants may be a source of alternative agents for mosquito control due to ever-growing insecticide resistance in mosquito vectors and

Integrative taxonomy supports DNA barcoding in revealing an abundant cryptic species in the United States Coastal Plain

open access: yesJournal of Systematics and Evolution, EarlyView.
We present the most densely sampled phylogeny of Carex section Lupulinae to date (107 specimens) and describe herein a new cryptic species for science from the southern United States, which is locally abundant and found in well‐explored and densely populated areas. Combining DNA sequences with morphometric data obtained from 299 samples, we Demonstrate

Automated extraction of leaf mass per area from digitized herbarium specimens

open access: yesNew Phytologist, EarlyView.
Summary The digitization of vast herbarium collections has made millions of plant specimen images freely available online, which can now be used to generate phenotypic datasets of unprecedented scope. Here, we assess the potential of computer vision tools to automate the extraction of predicted leaf mass per area (LMApred) from digitized herbarium ...

Nitrogen transfer from nitrogen-fixing lichen to co-occurring epiphytes in the subtropical forests of Yunnan

open access: yesGuangxi Zhiwu
Acquiring sufficient nitrogen(N)to meet requirements for growth is a major challenge for epiphytes living in nutrient-poor canopy habitats. Cyanolichens(lichens that contain cyanobacterial symbionts)can function as the primary participants in biological ...

Ecological drivers and phylogenetic patterns of leaf minimum conductance variability in vascular plants

open access: yesNew Phytologist, EarlyView.
Summary Stomatal closure prevents significant water losses during drought events. Yet, leaves are not perfectly hermetic and dehydration ensues through residual water losses, known as minimum conductance (gmin), which is highly relevant since it informs on the water depletion dynamics under stress.
