Carbon Stock and Environmental Variations of Typical Plantations in Mufu Mountain in Hubei Province, China

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Forest ecosystems play a critical role in the global carbon cycle. As a significant terrestrial carbon sink, plantations exhibit carbon stock patterns that are shaped by tree species composition, stand structure, and environmental conditions. Here, we investigated typical plantation types in the Mufu Mountain, Hubei Province.

Soil nematode communities in grasslands [PDF]

open access: yes, 2007
This thesis summarizes the results of five studies investigating the effect of plant species on soil nematode communities in grasslands. Nematodes (roundworms) are ubiquitous members of the soil fauna and have been much used as indicators of soil ...

Carbon, Nitrogen, and Corresponding Stable Isotope Signatures Reveal Channel Banks as Major Sediment Sources in a Tropical Agricultural Watershed

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Uncertainties about the applicability of δ13C and δ15N as tracers of sediment sources in tropical river basins highlight the need for more in‐depth investigations of these isotopes. This study therefore assessed the effectiveness of δ13C and δ15N signatures in discriminating sediment sources in an agricultural catchment in Northeast Brazil ...

The Endocrine Disrupting Compounds Bisphenol‐A and α‐Zeranol Mimic the Estrogen Transcriptional Program to Promote Proliferation and Stemness in Breast Cancer Cells

open access: yesMolecular Carcinogenesis, EarlyView.
ABSTRACT Excessive activation of the estrogen receptor (ER) drives proliferation, progression, and the formation of breast cancer stem cells (CSCs) in ER‐positive breast cancer. Estrogenic endocrine disrupting compounds (EDCs) found in plastics, water, and food are also able to bind to the ER.

A falácia da segurança alimentar

open access: yesCadernos de Campo, 2012
In the text we seek to reflect on some of the basis that structures the food security concept, identifying it functional and systemic character, shaped to perform the interests of the so-called agro business. We then seek to demonstrate that such concept

Functional diversity in agricultural landscapes: evidence of long‐term clustering and multi‐scale effects of land use on avian communities

open access: yesOikos, EarlyView.
Functional diversity (FD) is an essential community property connecting biodiversity, ecosystem functioning, and conservation objectives. In agricultural landscapes, avian communities, which play key functional roles, are facing large‐scale biodiversity erosion, largely due to land‐use changes.

Aquaculture technology adoption in Kapasia thana, Bangladesh: some preliminary results from farm record-keeping data [PDF]

open access: yes
A report on the adoption by target farmers of three aquaculture technologies in Kapasia Thana, Bangladesh. Preliminary results indicate that there were significant changes in fish production and resource use by farmer-cooperators from their previous ...

Linking regional and global functional trait data: insights from mammal communities in a fragmented Atlantic Forest landscape

open access: yesOikos, EarlyView.
Accurate functional trait data are essential for understanding ecosystem services and processes in fragmented landscapes. We evaluated whether the global EltonTraits 1.0 database adequately represents the functional structure of mammal communities in forest fragments and restoration sites in a highly fragmented Atlantic Forest landscape.

Enabling effective urban green space stewardship through planning: A qualitative comparative analysis in Southwest England

open access: yesPeople and Nature, EarlyView.
Abstract Amid increasing urbanisation and biodiversity decline, ‘effective stewardship’ of urban green space (UGS) is a complex but critical nature‐based solution for long‐term environmental, social and economic gain. Combining stewardship and sense‐of‐place frameworks with European nature‐based solutions guidance, we investigate which social and ...
