A twofold development and demise of pine stands in the Netherlands during the Allerød interstadial: two hypotheses to explain a link to climate change recorded in Greenland ice

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The second half of the Allerød interstadial in the Netherlands is characterised by pine forest. Excavated trunks of 165 pine trees at Leusden‐Den Treek in the central Netherlands (LETR16) were dated by dendrochronology and radiocarbon. Two chronologically separated pine forest phases occurred during relatively warm periods as recorded in ...

Population biology of the sea star Anasterias minuta (Forcipulatida: Asteriidae) threatened by anthropogenic activities in rocky intertidal shores of San Matías Gulf, Patagonia, Argentina [PDF]

open access: yes, 2017
In Patagonian coastal areas, intertidal benthic communities are exposed to extreme physical conditions. The interaction between harsh environment and anthropogenic pressure can generate changes in population biology of marine invertebrates, like density ...

Aquatic and Littoral Successions in Various Post‐Mining Sites—Patterns and Possible Use in Ecological Restoration

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Vegetation succession in aquatic and littoral habitats has received much less attention than terrestrial habitats have. We sampled differently aged successional stages at five different types of post‐mining sites, that is, sandpits, stone quarries, clay quarries, brown coal spoil heaps and black coal subsidences, across the Czech Republic ...

Does Palsa Thaw in Northern Finland Contribute to Remobilisation of Metals Accumulated in Peat Into Surface Waters?

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Permafrost is rapidly degrading in the sporadic zone, including palsa mires in Scandinavia. Peatlands in the area have likely accumulated heavy metals from atmospheric deposition of industrial contaminants in the wider region. As the palsa mire chemical composition is not well known, and in other permafrost regions the permafrost thaw may ...

Additions to the bryophyte flora of Réunion (East African Islands) [PDF]

open access: yes, 2000
Nineteen species of bryophytes are reported for the first time for Réunion. Especially remarkable are the first African record of Anastrophyllum leucocephalum (Tayl.) Steph. and the first records for the East African Islands of Cephaloziella cf. vaginans

Corrosion Performance of Prepainted Galvanized Steel After 8‐Year Outdoor Exposure Upon the Distance to the Seashore in Temperate Environment

open access: yesMaterials and Corrosion, EarlyView.
The corrosion performance of line‐produced prepainted galvanized steel products was investigated upon the distance to the seashore in temperate environment over 8‐year exposure. The rate of underpaint corrosion from cut‐edge was estimated and depended on the agressiveness of the site and the angle of exposure.

A survey of selected coastal vegetation communities of Florida [PDF]

open access: yes, 1977
A survey of coastal vegetation around Florida was conducted during 1973 and 1974. Seventeen sites were selected and sampled using the transect method to determine species occurrence, relative densities, and habitat development and structure.
