Abstract:

Abstract Peat bogs and specially raised bogs are vulnerable ecosystems all over the world and they create refuges for some rare plant species. The aim of this paper is to provide information regarding the conservation status of five oligotrophic peat bogs situated in the volcanic mountains in the Oriental Chain of Carpathians, in Maramureș County. The studied peat bogs are: Tăul lui Dumitru (Dumitru Pond), Mlaștina Vlășinescu (Vlășinescu Peat bog), Iezeru Mare (Big Tarn), Tăul Chendroaiei (Chendroaiei Pond) and Tăul Negru (Black Pond), all of them have the status of nature reserve and under th

Abstract:

Paleoecological data can be used to inform nature conservation practice. Dream Lake (DL) is the best-preserved peat bog in the Tatun Volcanic Group of northern Taiwan. We analyzed continuous pollen and charcoal data from a well-dated sediment core from DL to reconstruct the changes in climate, lacustrine condition, and floristic diversity during the last 4500 cal BP. An absence of volcanic ash from all sediments indicates weak volcanic activity. Significant changes in lithology and pollen composition show that DL changed from a deep lake to a shallow peat bog from 3000 cal BP onwards. The paly

Abstract:

The vast peatlands of the European North of Russia were drained in the 20th century. Some of the drained areas were left without management and maintenance, which led to re-waterlogging. The current trend towards peatlands restoration requires an understanding of all the changes that have taken place in such ecosystems. The study aims to assess the changes in vegetation cover relative to changes in peat deposits in the rewetted oligotrophic bogs. The objects of research were located on the south-White Sea oligotrophic bogs. The studies were carried out using generally accepted geobotanical and

Blanket mires extend over approximately 22,500 km2 of the north and west of the British Isles, and are of both national and international importance. Blanket peat started to form locally in some regions 9400 years ago, but the period of most active spread was between 5100 and 3100 BP. Clearance of forest and scrub by human activity probably triggered peat formation in many areas, though the influence of longer term changes in climate can be detected both in the times of peat initiation and in subsequent peat growth.

Investigation has shown that in peat‐bog sites active vegetation period temperature higher than the long‐term average influences the formation of radial increment positively (r = 0.22–0.34; p < 0.0

Abstract. Dust deposition in southern Belgium is estimated from the geochemical signature of an ombrotrophic peatland. The Rare Earth Elements (REE) and lithogenic elements concentrations, as well as Nd isotopes, were determined by HR-ICP-MS and MC-ICP-MS respectively, in along a ~6 m peat section covering 5300 yr, from 30 BC to 5300 BC dated by the 14C method. Changes in REE concentration in the peat correlate with those of Ti, Al, Sc and Zr that are lithogenic conservative elements, suggesting that REE are immobile in the studied peat bogs and can be used as tracers of dust deposition.

Abstract:

Dust deposition in two ombrotrophic peatlands (Baie and Ile du Havre peatland (IDH) bogs) of the Estuary and Gulf of the St. Lawrence in eastern Canada was reconstructed using elemental geochemistry. The rare earth elements (REEs) and other lithogenic element concentrations were measured by ICP-oES and Q-ICP-MS along two peat cores spanning the last 4000 years. Principal component analyses on the geochemical profiles show that REEs display the same behavior as Al, Ti, Sc, and Zr, all conservative elements, which suggests that REEs are immobile in the studied peat bogs and can be used as tracer

Abstract:

The objective of this work was to evaluate the effects of KMnO4 on the extension of postharvest life of 'Sunrise Golden' papaya, stored under modified atmosphere and refrigeration. Fruit with up to 10% yellow peel were harvested in a commercial orchard in Linhares, state of Espírito Santo, Brazil. Sets of three fruit (unit mass of 289.9±18.5 g) were wrapped in low-density polyethylene films (28 ¼m thick) containing sachets of KMnO4 at 0, 0.5, 1, 1.5, and 2 g per bag. The bags were sealed and stored at 10.4±0.9°C and 90±5% relative humidity for 25 days. After this period, the fruit were removed

Two studies determined relations between state resident Big Five personality scores and state work satisfaction for the 50 states in the United States. Study 1 and 2 personality profiles were based on responses of 619,397 residents to the 44-item Big Five Inventory. For Studies 1 and 2, state work satisfaction scores were respectively taken from the Gallup-Healthways Well-Being Index based on 353,039 phone interviews in 2008 and on 353,564 in 2012. Higher neuroticism was associated with lower work satisfaction ( r = −.49, p < .001) in both studies despite negative recession impacts in Study

Abstract:

A particular kind of quintessence is considered, with equation of motion pQ/ρQ=-1, corresponding to a cosmological term with time-dependence Λ(t)=Λ(t0)(R(t0)/R(t))P which we examine initially for 0≤P<3. Energy conservation is imposed, as is consistency with big-bang nucleosynthesis, and the range of allowed P is thereby much restricted to 0≤P<0.2. The position of the first Doppler peak is computed analytically and the result combined with analysis of high-Z supernovae to find how values of Ωm and ΩΛ depend on P. Some comparison is made to the CMBFAST public code.

Abstract:

The πN system in [Formula: see text] is limited to be pure isospin 1/2 due to isospin conservation. This is a big advantage in studying N*→πN from the J/ψ decays, compared with πN and γN experiments which mix isospin 1/2 and 3/2 for πN system. Based on the 58 million J/ψ data collected at the Beijing Electron Positron Collider, [Formula: see text] and other decay channels are analyzed. In the decay [Formula: see text], three peaks show up very clearly at 1400 MeV/c2, 1500 MeV/c2 and 1670 MeV/c2 in the πN invariant mass spectrum with additional peak around 2030 MeV/c2 which may be caused by a n

Abstract:

Abstract. Seasonal variation in water table depth (WTD) determines the balance between aggradation and degradation of tropical peatlands. Longer dry seasons together with human interventions (e.g. drainage) can cause WTD drawdowns making tropical peatland C storage highly vulnerable. Better predictive capacity for effects of WTD on net CO2 exchange is thus essential to guide conservation of tropical peat deposits. Mathematical modelling of basic eco-hydrological processes under site-specific conditions can provide such predictive capacity. We hereby deploy a process-based mathematical model ec

Abstract. Southeast Asian peatlands supply ∼10 % of the global flux of dissolved organic carbon (DOC) from land to the ocean, but the biogeochemical cycling of this peat-derived DOC in coastal environments is still poorly understood. Here, we use fluorescence spectroscopy and parallel factor (PARAFAC) analysis to distinguish different fractions of dissolved organic matter (DOM) in peat-draining rivers, estuaries and coastal waters of Sarawak, Borneo. The terrigenous fractions showed high concentrations at freshwater stations within the rivers, and conservative mixing with seawater across the e

Abstract:Discussions about looted antiquities often focus on large, culturally and monetarily valuable items. Nevertheless, it is clear that mundane small finds, which sell for relatively small amounts, account for a large portion of the global market in antiquities. This article highlights two types of small artifacts—namely, cylinder seals and coins, presumed to come from Syria and Iraq and offered for sale by online vendors. We argue that the number of cylinder seals and coins sold on the Internet has increased steadily since 2011, reaching a peak in 2016–17. This shows that the trade in Ir
