When 2 Mha of Amazonian forests are disturbed by selective logging each year, more than 90 Tg of carbon (C) is emitted to the atmosphere. Emissions are then counterbalanced by forest regrowth. With an original modelling approach, calibrated on a network of 133 permanent forest plots (175 ha total) across Amazonia, we link regional differences in climate, soil and initial biomass with survivors' and recruits' C fluxes to provide Amazon-wide predictions of post-logging C recovery. We show that net aboveground C recovery over 10 years is higher in the Guiana Shield and in the west (21 ±3 Mg C ha-1) than in the south (12 ±3 Mg C ha-1) where environmental stress is high (low rainfall, high seasonality). We highlight the key role of survivors in the forest regrowth and elaborate a comprehensive map of post-disturbance C recovery potential in Amazonia.

Tropical rainforests support critical biogeochemical cycles regulated by complex plant-soil microbial interactions but are threatened by global change. Much of the uniquely biodiverse and carbon rich forest on Borneo has been lost through extensive conversion to monoculture plantation, and a significant proportion of the remaining forest has been heavily modified by selective logging. Ecological restoration of tropical forest aims to return forests to a near pristine state, but restoration initiatives are hindered by limited understanding of the underpinning plant-soil feedbacks, and impacts on soil microbial communities are unresolved.

Borehole nuclear magnetic resonance (NMR) can be used to estimate the hydraulic conductivity (K) of unconsolidated materials. Various petrophysical models have been developed to predict K based on NMR response, with considerable efforts on optimizing site-specific constants. In this study, we assessed the utility of NMR logs to estimate K within highly heterogeneous glaciofluvial deposits by comparing them with K measurements from three types of co-located hydraulic testing methods, including permeameter, multi-level slug, and direct-push hydraulic profiling tool (HPT) logging tests.

The quantification of movable shale oil is crucial for the effective exploration and development of shale oil resources. Nuclear magnetic resonance (NMR), a nondestructive and noninvasive technique, has become an indispensable tool for evaluating movable oil saturation. However, the small core sizes, high-frequency instrumentation, costly measurements, and significant losses of light hydrocarbons pose substantial challenges in accurately assessing movable oil.

Narwhals (Monodon monoceros) are deep-diving Arctic cetaceans that migrate seasonally between summering and wintering grounds. The Baffin Bay population overwinters in southern Baffin Bay and Davis Strait, where they are known to forage on high-energy benthic prey. Studying narwhal winter behaviour and prey preference has been challenged by their remote distribution and limited lifespan of satellite tags deployed in summer, restricting data on their habitat use and foraging strategies.

Background: Exclusive breastfeeding is essential for optimal infant nutrition and health, yet many mothers experience concerns about insufficient milk supply. This study investigated the effects of a ginger-spiced millet-soya drink (Zim-So drink), selected for its rich content of phytoestrogens and cultural use as a galactagogue and breastfeeding education on breast milk volumes and prolactin levels to enhance breastfeeding experiences among postpartum mothers in Tamale, Northern Ghana.
Method: A randomized-controlled intervention study was conducted, with 75 participants randomly assigned to three groups: Zim-So drink (n = 25), breastfeeding education (n = 25), or control (n = 25).
