Do the recent severe droughts in the Amazonia have the same period of length? [PDF]

, 2015
We propose a new measure based on drought period length to assess the temporal difference between the recent two severe droughts of 2005 and 2010 in the Amazonia. The sensitivity of the measure is demonstrated by disclosing the distinct spatial responding mechanisms of the Northeastern and Southwestern Amazon (NA, SA) to the surrounding sea surface ...

Reconstructing the late Pleistocene glacial history of the Cairngorm Mountains, Scotland, using paired cosmogenic 10Be and 14C

Journal of Quaternary Science, EarlyView.
ABSTRACT Chronologic and geomorphic evidence of past glaciations is largely recorded in areas at relatively low elevation and/or landscapes defined by high glacial erosion. As a result, data from areas that did not experience significant glacial erosion and the highest elevation locations are lacking from reconstructions of past ice masses.

Is there a hot spot of sea-level rise acceleration along the mid-Atlantic United States? A Gaussian process decomposition of tide gauge records [PDF]

arXiv, 2013
To test a hypothesized faster-than-global sea-level acceleration along the mid-Atlantic United States, I construct a Gaussian process model that decomposes tide gauge data into short-term variability and longer-term trends, and into globally-coherent, regionally-coherent and local components.

Challenges in dating blanket peat and implications for understanding its initiation in Ireland

Journal of Quaternary Science, EarlyView.
ABSTRACT Blanket peat is widespread in maritime extra‐tropical environments. Prehistoric land‐use activity was traditionally invoked as the stimulus of blanket peat initiation in the British Isles, but recently, climate has been viewed as the driver of peat formation.

Development of alternative feed with seed and insect meal for sustainable production of rainbow trout (Oncorhynchus mykiss) and quality fillets

JSFA reports, EarlyView.
Abstract Background Rainbow trout (Oncorhynchus mykiss) is a freshwater fish with an aquaculture industry widely distributed throughout the world, whose diet is based on fish meal (marine origin), with serious sustainability problems associated with the sector. The objective of the study was the inclusion of other flours as a protein source (insect and

Sixty Years of Sugarcane Monoculture Alters Carbon Preservation in Large Soil Macroaggregates in Tropical Soil

Land Degradation &Development, EarlyView.
ABSTRACT Frequent and intensive tillage in conventional agriculture disrupts soil aggregates, engendering significant depletion of soil organic carbon (SOC) stocks. Long‐term studies are essential for assessing the impact of sustainable practices on aggregate dynamics and carbon sequestration in sugarcane monocropping in tropical ecosystems.

Assessing the Acoustic Landscape and Vegetational Structure of a Mining Area Undergoing Restoration for Over 30 Years

Land Degradation &Development, EarlyView.
ABSTRACT Mining causes substantial changes in urban and natural ecosystems, making land restoration an essential step along the mining process and after mine closure. Here, we elucidate the soundscape and vegetation structure of a recently closed mine site under restoration over the past 30 years.

Autonomous observations enhance our ability to observe the biological carbon pump across diverse carbon export regimes

Limnology and Oceanography, EarlyView.
Abstract The expansion of autonomous observation platforms offers vast opportunities for analyzing ocean ecosystems and their role in carbon export. As part of the EXport Processes in the Ocean from RemoTe Sensing campaign, we autonomously measured the productivity regimes in two contrasting end‐member ecosystem states.

Overlooked Bird Extinctions in Semideciduous Atlantic Forests

Ecology and Evolution
ABSTRACTThe semideciduous forest is a prominent yet highly degraded phytophysiognomy within the Atlantic Forest. Historically, bird species inhabiting these forests occurred throughout central and western São Paulo state, south‐eastern Brazil, until the mid‐20th century.
