Effects of soil physical properties on dung beetle assemblages in pasture landscapes of the Brazilian Cerrado

open access: yesAgricultural and Forest Entomology, EarlyView.
We assessed the effect of the type of soil texture (loamy sand and sandy loam) and its physical properties on dung beetle species assemblages in a pastureland region of the Brazilian Cerrado. We found a reduction in the total and paracoprid beetle abundances in loamy sand soil. Furthermore, the increase of soil compaction negatively affected the entire

The Nasal Microbiome and Associations With Environmental Exposures and Respiratory Health

open access: yesAllergy, EarlyView.
This study evaluates the association of the nasal microbiome with air pollutants, meteorological conditions, and respiratory health in adolescents. Bacterial diversity is positively associated with hay fever and short‐term NO2 exposure, and negatively with temperature. A Moraxella‐dominated nasotype is linked to lower O3 exposure and higher temperature

Vitamin D levels and biomarkers of male fecundity: A study from the Danish National Birth Cohort

open access: yesAndrology, EarlyView.
Abstract Background Vitamin D is metabolised throughout the male reproductive system, suggesting a direct regulatory role of vitamin D in male reproduction. Objectives To investigate the association between plasma vitamin D levels at sperm ejaculation and during spermatogenesis and biomarkers of male fecundity in young men.

Single‐dose Pasteurella multocida and Histophilus somni autogenous vaccines administered at induction significantly improved feedlot cattle performance and profitability in Australia

open access: yesAustralian Veterinary Journal, EarlyView.
Background Bovine respiratory disease (BRD) is the most economically important disease affecting feedlot cattle. While viral pathogens are initiating agents, bacterial coinfections exacerbate disease severity. Vaccines for Pasteurella multocida and Histophilus somni are not commercially available in Australia.

Peri‐Implant Crevicular Fluid Analysis by Mid‐Infrared Spectroscopy in Peri‐Implantitis—A Pilot Study

open access: yesClinical Oral Implants Research, EarlyView.
ABSTRACT Objectives This study aimed to assess biochemical differences in peri‐implant crevicular fluid (PICF) using ATR‐FTIR spectroscopy and multivariate analysis, through a between‐participant comparison of healthy and peri‐implantitis (PI) sites, and a within‐participant comparison of PI‐PICF and GCF from contralateral periodontal healthy teeth ...

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas

open access: yesConservation Biology, EarlyView.
Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

Knowledge, perceptions, and barriers influence public actions to help bees in Toronto, Canada

open access: yesConservation Science and Practice, EarlyView.
Abstract Despite the enthusiasm surrounding bees, the public's current knowledge is sourced from the non‐native honey bee whose life history differs from many endemic North American species. Ascertaining the public's understandings and perceptions of bees is essential to implementing publicly supported conservation initiatives that may benefit bee ...

Efficient multiplication for finite fields of p characteristic

open access: yesTongxin xuebao, 2009
Based on residue arithmetic,a new form of polynomial named PAPB in Fp[x] had been constructed.The amount and distribution of such irreducible polynomials had also been investigated.Then,an efficient algorithm for multiplication modulo PAPB had been ...

Moduli space of filtered λ-ringstructures over a filtered ring

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
Motivated in part by recent works on the genus of classifying spaces of compact Lie groups, here we study the set of filtered λ-ring structures over a filtered ring from a purely algebraic point of view. From a global perspective, we first show that this

Mapping bee diversity with landscape‐level models to inform conservation

open access: yesConservation Science and Practice, EarlyView.
Native bee conservation is complicated by limited distribution data and life history knowledge. However, recent state‐wide pollinator surveys, combined with species distribution models that account for biased datasets and capture regional habitat associations, present a strong foundation for informing essential conservation action.
