Erosive effect of different dietary substances on deciduous and permanent teeth. [PDF]
, 2017 OBJECTIVES We investigated the effect of different dietary substances on deciduous and permanent enamel. MATERIALS AND METHODS Enamel specimens were prepared from human teeth (n = 108 deciduous molars and n = 108 permanent premolars).

Holocene vegetation change and fire–plant diversity shifts in Mediterranean France
Journal of Quaternary Science, EarlyView.ABSTRACT Changes in fire activity are recognized as a major threat to biodiversity and vegetation communities across the Mediterranean Basin. However, long‐term fire–vegetation interactions remain poorly investigated. Here, we combine a high‐resolution charcoal record with pollen data from the “Étang des Aulnes” lake (southern France) to reconstruct ...

Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND The present study investigated the potential health risks of heavy metals (HMs) in the fruits and leaves of mulberry and sour cherry trees exposed to water from Sivas geothermal basin (Turkey). RESULTS The target HMs were ranked according to their hazard index as: Cd < Pb < Zn < Cu < Ni < Mn < Cr. The total hazard index for mulberry

Ringtail (Bassariscus astutus) survival in southwestern Oregon
The Journal of Wildlife Management, EarlyView.We captured and monitored radio‐collared ringtails over 2 years to estimate monthly and annual survival rates. We found that annual survival rates were much higher within forested landscapes in Oregon than for populations in the southwestern United States.

Living on the edge: Habitat characteristics of northern myotis at the periphery of its distribution
The Journal of Wildlife Management, EarlyView.Northern myotis selected tall trees with minimal decay, in patches with other roosting options. In our study area, these trees occurred in narrow bands within an agricultural matrix, differing from contiguous forest at the core of the species' distribution. Nevertheless, bats selected the tallest trees in the densest patches available.

Topographic and Climatic Determinants of Soil Organic Carbon Across Landscapes: A Meta‐Analysis
Land Degradation &Development, EarlyView.ABSTRACT The soil is the greatest natural store of organic carbon, holding between 1500 to 1550 Pg C of organic carbon at the top 100 cm of the soil globally—roughly twice the carbon pool in the atmosphere. The spatial distribution of this stock is controlled by a complex chain of controls: topographic position regulates the hydrological redistribution,

Land Degradation &Development, EarlyView.ABSTRACT Previous studies often overlooked the dynamic effects of karst vegetation restoration on soil multi‐trophic biodiversity and the underlying community‐assembly mechanisms. To fill this gap, we performed a seasonal comparative analysis of soil biodiversity, co‐occurrence network architecture, and assembly processes across three representative ...
