Current temporal trends in moth abundance are counter to predicted effects of climate change in an assemblage of subarctic forest moths
(InterceptWiley Periodicals, Inc., 2014-06)
Changes in climate are influencing the distribution and abundance of the world's biota, with significant consequences for biological diversity and ecosystem processes. Recent work has raised concern that populations of ...
A boundary current drives synchronous growth of marine fishes across tropical and temperate latitudes
(R Foundation for Statistical ComputingWiley Periodicals, Inc., 2018-05)
Entrainment of growth patterns of multiple species to single climatic drivers can lower ecosystem resilience and increase the risk of species extinction during stressful climatic events. However, predictions of the effects ...
Export Production in the Subarctic North Pacific over the Last 800 kyrs: No Evidence for Iron Fertilization?
(Kluwer Academic Publishers; The Oceanographic Society of Japan ; Springer Science+Business Media, 2004-01)
The subarctic North Pacific is a high nitrate-low chlorophyll (HNLC) region, where phytoplankton growth rates, especially those of diatoms, are enhanced when micronutrient Fe is added. Accordingly, it has been suggested ...
Chemistry and decomposition of litter from Populus tremuloides Michaux grown at elevated atmospheric CO 2 and varying N availability
(Blackwell Science Ltd, 2001-01)
It has been hypothesized that greater production of total nonstructural carbohydrates (TNC) in foliage grown under elevated atmospheric carbon dioxide (CO 2 ) will result in higher concentrations of defensive compounds in ...
Effects of elevated atmospheric carbon dioxide on amino acid and NH 4 + -N cycling in a temperate pine ecosystem
(Blackwell Publishing Ltd, 2007-09)
Rising atmospheric carbon dioxide (CO 2 ) is expected to increase forest productivity, resulting in greater carbon (C) storage in forest ecosystems. Because elevated atmospheric CO 2 does not increase nitrogen (N) use ...
Extinction vulnerability of tropical montane endemism from warming and upslope displacement: a preliminary appraisal for the highest massif in Madagascar
(Blackwell Publishing Ltd, 2008-08)
One of the predicted biological responses to climate warming is the upslope displacement of species distributions. In the tropics, because montane assemblages frequently include local endemics that are distributed close ...
Forest fine-root production and nitrogen use under elevated CO 2 : contrasting responses in evergreen and deciduous trees explained by a common principle
(Blackwell Publishing Ltd, 2009-01)
Despite the importance of nitrogen (N) limitation of forest carbon (C) sequestration at rising atmospheric CO 2 concentration, the mechanisms responsible are not well understood. To elucidate the interactive effects of ...
Photosynthesis, carboxylation and leaf nitrogen responses of 16 species to elevated pCO 2 across four free-air CO 2 enrichment experiments in forest, grassland and desert
(Blackwell Science Ltd, 2004-12)
The magnitude of changes in carboxylation capacity in dominant plant species under long-term elevated CO 2 exposure (elevated pC a ) directly impacts ecosystem CO 2 assimilation from the atmosphere. We analyzed field CO 2 ...
From endogenous to exogenous pattern formation: Invasive plant species changes the spatial distribution of a native ant
(Wiley Periodicals, Inc.Chapman and Hall, 2017-06)
Invasive species are a significant threat to global biodiversity, but our understanding of how invasive species impact native communities across space and time remains limited. Based on observations in an old field in ...
Seedling survival in a northern temperate forest understory is increased by elevated atmospheric carbon dioxide and atmospheric nitrogen deposition
(Blackwell Publishing Ltd, 2007-01)
We tested the main and interactive effects of elevated carbon dioxide concentration ([CO 2 ]), nitrogen (N), and light availability on leaf photosynthesis, and plant growth and survival in understory seedlings grown in an ...
