open access: yesCurtis's Botanical Magazine, EarlyView.
Summary Allium kollmannianum is a small, late‐spring to early‐summer blooming Allium, endemic to the Negev Desert in south Israel, and previously thought to be extremely rare and critically endangered. Here we expand new information regarding its distribution and habitat in the Negev Desert, and a new estimation of its threat level, considering the new

Complete chloroplast genome sequence of Annamocarya sinensis (Juglandaceae), an endangered perennial plant

open access: yesMitochondrial DNA. Part B. Resources, 2019
Annamocarya sinensis (Juglandaceae) is a tertiary relict tree restricted to southeastern China and northern Vietnam. Here, we first report and characterize its complete chloroplast genome based on Illumina paired-end sequencing data. The complete plastid

Tetraether biomarker records from a loess-paleosol sequence in the western Chinese Loess Plateau

open access: yes, 2013
The ubiquitous occurrence of glycerol dialkyl glycerol tetraethers (GDGTs) in soils and their ability to record temperature and environmental changes offer the prospect of independently reconstructing continental paleotemperature and paleoenvironment ...

Measuring Thematic Funds Performance via an Approach Based on Observable and Latent Factors

open access: yesEuropean Financial Management, EarlyView.
ABSTRACT This paper investigates whether thematic equity funds deliver abnormal performance relative to conventional global equity funds. Using Fama‐French models augmented with latent factors, we estimate fund‐level alphas, and apply the false discovery rate methodology to an estimated three‐group mixture distribution, separating good, null and bad ...

Loess magnetic properties in the Ili Basin and their correlation with the Chinese Loess Plateau

open access: yes, 2010
     Over the past two decades, magnetoclimatological studies of loess-paleosol sequences in the Chinese Loess Plateau (CLP) have made outstanding achievements, which greatly promote the understanding of East Asian paleomonsoon ...

Identification of soil quality factors and indicators for the Loess Plateau of China

open access: yes, 2006
Soil quality has been significantly degraded in the Loess Plateau of China by soil erosion. Our objectives were to (i) identify regional-scale soil quality factors (groupings), (ii) select soil attributes within these factors that can be used as ...

Geolocation reveals wintering sites of near‐extinct Caucasian breeding sea duck

open access: yesIbis, EarlyView.
We obtained 14 sets of full annual cycle geolocator tracks from 13 individual nesting female Velvet Scoter Melanitta fusca from the relict Caucasian population at their last remaining breeding site, Lake Tabatskuri, Georgia. Results showed that females wintered at widespread discrete localities in Ukraine, around the coasts of the Crimean Peninsula and

Differential Effects of Age, Linguistic Distance, Gender, and Education on English Proficiency: A Comparative Crosslinguistic Study of Immersion and Nonimmersion Learners

open access: yesLanguage Learning, EarlyView.
Abstract Do immersion and nonimmersion learners’ English grammaticality judgment test (GJT) scores reflect the same underlying processes in language learning? Drawing on data from Chen and Hartshorne's (2021) study, we argue that they do not. Using generalized additive mixed models (GAMMs), we found that age of onset was the strongest predictor of GJT ...

Bacterial composition of Polygenis (Polygenis) bohlsi bohlsi (Wagner, 1901) (Siphonaptera: Rhopalopsyllidae) associated with Thrichomys fosteri (Rodentia: Echimyidae) in the Brazilian Pantanal wetland

open access: yesMedical and Veterinary Entomology, EarlyView.
This study characterizes the bacteriome of Polygenis (Polygenis) bohlsi bohlsi fleas collected from free‐living Thrichomys fosteri in the Pantanal region of Brazil. The bacterial microbiota associated with male fleas exhibited greater phylogenetic diversity, and the overall community structure differed between the flea sexes.
