Impacts of different intensities of commercial Sphagnum moss extraction on CO fluxes in a northern Patagonia peatland.

Peatlands are key ecosystems for global climate regulation because they provide the most efficient carbon sink on the planet. Despite this, they have been widely degraded by various anthropogenic disturbances, causing imbalances in their ecological functioning. A more recent type of disturbance corresponds to the commercial extraction of Sphagnum mosses, which has been carried out in temperate peatlands distributed in Australasia and Patagonia.

Purpose Of Review: This review outlines the prevalence and complications of apneas and intermittent hypoxemic events in preterm infants, examines current monitoring limitations in neonatal ICUs (NICUs), and explores emerging technologies addressing these challenges.
Recent Findings: New evidence from the Prematurity-Related Ventilatory Control (Pre-Vent) study, which analyzed cardiorespiratory data from 717 extremely preterm infants, exposes the varying frequency, duration, and severity of apneas, intermittent hypoxemia, bradycardias, and periodic breathing during hospitalization, and highlights the negative impact of intermittent hypoxemia on pulmonary outcomes at discharge. Although traditional monitoring methods cannot differentiate between apnea types and quantify their burden, recent advancements in sensor technologies and data integration hold promise for improving real-time detection and evaluation of apneas in the NICU.
Differential responses of plant and microbial respiration to extreme precipitation and drought during spring and summer in the Eurasian meadow steppe.

Electronic address:
Increasing extreme precipitation and drought events along changes in their seasonal patterns due to climate change are expected to have profound consequences for carbon cycling. However, how these climate extremes impact ecosystem respiration (R) and whether these impacts differ between seasons remain unclear. Here, we reveal the responses of R and its components to extreme precipitation and drought in spring and summer by conducting a five-year manipulative experiment in a temperate meadow steppe.

Chronic Obstructive Pulmonary Disease (COPD) is a heterogeneous disease with a variety of symptoms including, persistent coughing and mucus production, shortness of breath, wheezing, and chest tightness. As the disease advances, exacerbations, i.e.

While soundscapes shape the structure and function of auditory systems over evolutionary timescales, there is limited information regarding the adaptation of wild fish populations to their natural acoustic environments. This is particularly relevant for freshwater ecosystems, which are extremely diverse and face escalating pressures from human activities and associated noise pollution. The Siamese fighting fish is one of the most important cultured species in the global ornamental fish market and is increasingly recognized as a model organism for genetics and behavioural studies.
