ABSTRACT. Abundant fossil plant remains are preserved in the high-latitude late Paleocene Iceberg Bay Formation on Ellesmere Island, Nunavut, Canada. Intact leaf litter lenses and permineralized, in situ logs and stumps offer for the first time an opportunity to determine the structure, biomass, and productivity of a redwood-dominated forest that grew in the polar regions of Nunavut (paleolatitude 75–80° N). Well-preserved fossil tree trunks were excavated to develop equations that describe… 

Floral and environmental gradients on a late Cretaceous landscape

We describe an in situ fossil flora of Late Cretaceous age (∼73 Ma [mega-annum or million years]) from Big Cedar Ridge in central Wyoming, USA, which we sampled using a modified line-intercept method

PALEOBOTANICAL AND GEOCHEMICAL APPROACHES TO STUDYING FOSSIL TREE RINGS: QUANTITATIVE INTERPRETATIONS OF PALEOENVIRONMENT AND ECOPHYSIOLOGY

The proportions found in fossil wood can be compared to ring structures of modern wood to extrapolate the environmental causes determining ring formation, and several methods have been proposed to calculate density.

Structure of the 7 Ma Bükkábrány fossil forest in Hungary

An in situ late Miocene (Pannonian) fossil forest preserved as wood has been uncovered at Bukkabrany, Hungary. Excavation within the open-pit mine revealed 16 stumps that ranged from 1.8 to 3.6 m in

Arctic plant diversity in the Early Eocene greenhouse

The reduced latitudinal diversity gradient in Early Eocene North American plant species demonstrates that extreme photoperiod in the Arctic did not limit taxonomic diversity of plants.

ABSTRACT Megafossils and macrofossils of terrestrial plants (trees, leaves, fruiting bodies, etc.) are found in sedimentary and pyroclastic units interbedded with lavas in many ancient lava fields

Paleobotanical proxies for early Eocene climates and ecosystems in northern North America from mid to high latitudes

Early Eocene climates were globally warm, with ice-free conditions at both poles. Early Eocene polar landmasses supported extensive forest ecosystems of a primarily temperate biota but also with

The Hubbard Brook Ecosystem Study: Forest Biomass and Production

Analysis of stem wood volume reveals an abrupt and striking decrease in volume growth and productivity from 1956-60 to 1961-65, and both drought and effects of increasing air pollution may be responsible for the recent decrease in productivity.

A 50-Million-Year-Old Fossil Forest from Strathcona Fiord, Ellesmere Island, Arctic Canada: Evidence for a Warm Polar Climate

The remains of a fossil forest are buried within a sedimentary sequence of Eocene age (approximately 50 million years old) near Strathcona Fiord, Ellesmere Island. Large petrified tree stumps are

Community Structure, Dynamics and Nutrient Cycling in the Okefenokee Cypress Swamp-Forest

It appears that in recent years, above-water biomass has been maintained at a constant level by fire-induced thinning, and nutrients received from atmospheric precipitation are likely to be of special importance to the nutrition of this closed-basin swamp forest community.

Old‐Growth Pseudotsuga menziesii Communities of a Western Oregon Watershed: Biomass Distribution and Production Budgets

Living biomass, organic matter distribution, and organic matter production budgets were determined for plant communities of a small watershed dominated by 450—yr—old Pseudotsuga menziesii (Mirb.)

Environmental Limits on Aboveground Net Primary Production, Leaf Area, and Biomass in Vegetation Zones of the Pacific Northwest

Mature vegetation from eight of the 12 major vegetation zones in Oregon and Washington was sampled along a transect from the Pacific Coast to the east slopes of the Cascade Moun- tains, finding these systems receive more annual precipitation, and average twice the basal area and biomass.
