Spatial pattern development of selective logging over several years [PDF]

open access: yes, 2015
Selective logging gives currently a major contribution to ongoing deforestation in the Brazilian Amazonia. On satellite images, log-landing sites (LLS) are well visible, and they serve as a proxy to selective logging activities. In this study we analysed

Estimates of selective logging impacts in tropical forest canopy cover using RapidEye imagery and field data

open access: yesiForest - Biogeosciences and Forestry, 2016
Selective logging is one of the leading causes of forest degradation in the Brazilian Amazon region. The Brazilian Federal government has adopted a forest concession policy as a strategy to mitigate impacts of selective logging and regulate operations of

Serological Benefit of SARS‐CoV‐2 Vaccination Relative to Infection in Children With Acute Lymphoblastic Leukemia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with acute lymphoblastic leukemia (ALL) are at risk of severe outcomes from SARS‐CoV‐2 (SCV2). In the post‐pandemic context, where most children have been infected with SCV2, there are limited data on whether vaccination remains beneficial in children with ALL.

Responses of fruit-feeding butterflies to selective logging in Sabah, Borneo [PDF]

open access: yes, 2001
This study investigated the impacts of selective logging on tropical butterflies in lowland dipterocarp rainforest of Sabah, Malaysia (Borneo). Fruit-baited traps were used to survey butterflies in unlogged forest and forest that had been selectively ...

Evolutionary dynamics of selective logging in the tropics: a systematic review of impact studies and their effectiveness in sustainable forest management

open access: yes, 2018
Selective logging is the dominant timber harvesting practice in natural tropical forests. Considering its scale and its contribution to forest management outcome, efficient management of selective logging is crucial to address challenges associated with ...

Assessing impacts of selective logging on water, energy, and carbon budgets and ecosystem dynamics in Amazon forests using the Functionally Assembled Terrestrial Ecosystem Simulator [PDF]

open access: yesBiogeosciences, 2020
Tropical forest degradation from logging, fire, and fragmentation not only alters carbon stocks and carbon fluxes, but also impacts physical land surface properties such as albedo and roughness length.

The Role of Hematopoietic Cell Transplantation in Ataxia‐Telangiectasia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Ataxia‐telangiectasia (A‐T) is a DNA repair disorder characterized by neurodegeneration, immunodeficiency, and cancer predisposition. Hematopoietic cell transplantation (HCT) is an established therapy in related disorders such as Fanconi anemia (FA) and Nijmegen breakage syndrome (NBS), but its role in A‐T is unclear.

Selective logging and damage to unharvested trees in a hyrcanian forest of Iran [PDF]

open access: yesBioResources, 2012
Selective logging in mature hardwood stands of Caspian forests often causes physical damage to residual trees through felling and skidding operations, resulting in a decline in bole quality and subsequent loss of tree value.

Change Detection of Selective Logging in the Brazilian Amazon Using X-Band SAR Data and Pre-Trained Convolutional Neural Networks

open access: yesRemote Sensing, 2021
It is estimated that, in the Brazilian Amazon, forest degradation contributes three times more than deforestation for the loss of gross above-ground biomass. Degradation, in particular those caused by selective logging, result in features whose detection

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.
