Bite force estimates and morphological correlations of jaw muscles in parrots

open access: yesThe Anatomical Record, EarlyView.
Abstract Parrots (Order: Psittaciformes) are renowned for their high bite force (BF) and morphological correlates thereof, including a highly mobile skull and two unique mandibular adductor muscles—m. pseudomasseter and m. ethmomandibularis, with the former being hypothesized to increase force output.

Lichen cover mapping for caribou ranges in interior Alaska and Yukon

open access: yesEnvironmental Research Letters, 2020
Previous research indicates that the effects of climate warming, including shrub expansion and increased fire frequency may lead to declining lichen abundance in arctic tundra and northern alpine areas. Lichens are important forage for caribou ( Rangifer

Biocrust effects on soil infiltrability in the Mu Us Desert: Soil hydraulic properties analysis and modeling

open access: yesJournal of Hydrology and Hydromechanics, 2021
The presence of biocrusts changes water infiltration in the Mu Us Desert. Knowledge of the hydraulic properties of biocrusts and parameterization of soil hydraulic properties are important to improve simulation of infiltration and soil water dynamics in ...

A Systemic Model for Understanding Business Interactions With Biodiversity and Ecosystems

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Biodiversity loss and ecosystem degradation represent critical threats to human well‐being and economic resilience, challenging businesses to understand and manage their interdependence with natural systems. This study develops a systemic framework—the BioModel—that elucidates the reciprocal relationship between businesses, biodiversity, and ...

Continental scale comparison of mycobiomes in Parmelia and Peltigera lichens from Turkey and South Korea

open access: yesBMC Microbiology
Background Lichens, traditionally considered as a simple partnership primarily between mycobiont and photobiont, are, in reality, complex holobionts comprised of a multitude of microorganisms.

Two New Species of the Genus Candelariella from China and Korea

open access: yesMycobiology, 2019
Candelariella is a widespread lineage of lichenized ascomycetes with ambiguous relationships among species that have not solved completely. In this study, several specimens belonging to Candelariella were collected from China and South Korea, and the ...

Long‐term outcomes of microsurgical interdental papilla reconstruction: 13‐year and 18‐year case follow‐ups

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background Loss of the interdental papilla compromises esthetics, speech, and hygiene, significantly affecting quality of life and psychological well‐being. Reconstruction has long been considered unpredictable, particularly in Cairo RT3 cases with advanced interproximal bone loss.

Estimation of lichen biomass with emphasis on reindeer winter pastures at Hardangervidda, S Norway

open access: yesRangifer, 2014
Quantification of lichen abundance is important for management of reindeer populations. We measured dry lichen biomass in 876 micro plots (16.5 cm × 16.5 cm) systematically sampled within 219 vegetation plots (2 m × 2 m) from 7 different areas in S ...

Increase in plant productivity in the tundra in Sweden is not related to increasing presence of warm‐adapted vascular plant species

open access: yesEcography, EarlyView.
Over the past decades, Arctic and alpine biomes have warmed faster than the global average. Substantial vegetation changes have been reported as a response to this warming, including increased productivity and the spread of warm‐adapted (thermophilic) species that are less resistant to grazing pressure into higher latitudes and altitudes.

Lichen Sclerosus

open access: yesActas Dermo-Sifiliográficas (English Edition), 2010
Lichen sclerosus is a chronic inflammatory mucocutaneous disease that is highly bothersome for men and women of all ages. The exact etiology is unknown, although genetic and autoimmune factors, as well as infections, have been implicated in its pathogenesis. First-line treatment is highly potent topical corticosteroid therapy for short periods. Surgery
