Summary: This study investigates the impact of dry forest biomass fluctuation on connectivity in tropical dry forests, using vegetation scenarios based on rainfall patterns and NDVI fluctuations. Results show that potential connectivity increases during wet scenarios and decreases during dry scenarios, indicating temporal variability in connectivity in runoff-dominated regions.

Summary: Seed-rain-successional feedbacks play a deterministic role in shaping successional trajectories in secondary wet forests, with increasing strength as the forest ages. The composition of seed rain becomes more similar to that of mature forests as successional niches and seed-rain-successional feedbacks shape successional trajectories.

Summary: Recent studies have identified fog-driven epiphyte-rich tropical cloud forests in the lowlands of French Guiana. A high-resolution product based on satellite images has shown widespread occurrence of fog/low stratus clouds (FLS) in the entire tropical lowland rain forest of South America, providing suitable environmental conditions for the Tropical Lowland Cloud Forest (TLCF). This knowledge on the spatial distribution of potential TLCF is crucial for conservation efforts.

Summary: Governments are increasingly investing in forest restoration for carbon sequestration and community benefits. However, the impacts of forest restoration on local hydrological services are poorly understood. Research shows that regenerating tropical forest vegetation can positively contribute to locally important hydrological ecosystem services.

Summary: This study assesses the ecohydrological effects of recent meteorological droughts in tropical South America and investigates the mechanisms underlying the drought response and recovery of different ecohydrological systems. The study finds that the response and recovery of soil drought lag behind meteorological drought, and the differences are more pronounced in different regions and soil depths. Additionally, the replenishment of soil moisture plays a crucial role in the recovery process.

Summary: This study found that light can initiate seed germination of certain species in the soil seed bank when a gap is formed in closed-canopy forests. However, temperature alone cannot trigger seed germination. The combined effect of light and temperature can initiate seed germination of more species.

Summary: The study found that functional diversity, redundancy and over-redundancy were positively correlated with species richness, while functional vulnerability was negatively correlated with species richness in old-growth tropical forests. The null model tests revealed that species in each forest type were packed into a few functional entities, resulting in functional over-redundancy and vulnerability. Functionally diverse tropical forests may have high probability of redundancy, but it cannot fully offset functional vulnerability in the ecosystems.

Summary: The ordination of tropical rain forest plots based on stand-level structural attributes often demonstrates a gradient from poorly stocked to highly stocked plots, along with strong positive correlations between biomass, basal area, and the number of large trees. By filtering out patterns inherited from individual trees, this study unveiled hidden site differences that provide more information on ecological processes, such as different histories of large-scale forest disturbance.

Summary: Recent studies have found that climate warming is causing a delay in tropical rainfall over land due to the increasing influence of greenhouse gases and anthropogenic aerosols. This delay, primarily driven by external forcings, is expected to further amplify in the future as greenhouse gases increase and aerosols decrease.

Summary: The study reveals that Ecuador's seasonal dry forests faced deforestation and fragmentation between 1990 and 2018, with semi-deciduous forests experiencing the highest levels of fragmentation. National protected areas had lower levels of fragmentation, while protected forests had higher levels of fragmentation.

Summary: Global tropical deforestation rates are rising, particularly in arable landscapes of West Africa where remaining forest fragments are highly fragmented. This study aims to inventory and characterize these forest patches using remote sensing, finding that while larger patches may experience more loss on average, smaller secondary forest patches persist in the landscape. Larger forest patches also harbor denser tree cover and higher trees, indicating potential resilience to human pressures.

Summary: This study investigated the biodiversity and distribution of longhorn beetles across different elevation gradients and seasons in six regions of Thailand. A total of 199 morphospecies were identified from 1376 specimens collected by malaise traps. Longhorn beetles showed a peak in species richness and abundance during the hot and early rainy season, except for the southern region which peaked in the rainy season. The study concluded that the distribution of most species was correlated with regions and forest type at middle and low elevations.

Summary: Research findings suggest that rain events do not significantly impact the diversity and composition of phyllosphere microbial communities, indicating their resilience to such disturbances. Long-term climatic variations are shown to be the main factor influencing the phyllosphere community.

Summary: Oxygen in cells has a dual nature, serving both as an energy source and a potential source of damage through reactive oxygen species. The mechanisms for handling oxygen have evolved to maintain cellular homeostasis, with protection as a fundamental principle. Understanding these basic mechanisms is important for disease pathogenesis and maintaining health.

Summary: Driptips play important roles in controlling soil erosion and in the water cycle. The size distribution and morphology of water droplets on the leaves were measured for different species, and it was found that the size of the driptips and the wettability of the leaves were correlated. The study highlights the importance of considering the kinetic energy of driptips in selecting intercropping species, and it can help predict canopy water processes.

Summary: This study identified non-cyclic nucleotide partial agonists of EPAC1 that are well tolerated and effective binders. These activators regulate genes associated with endothelial activation and suppress IL-6-induced STAT3 activation. These findings are important for the development of specific and non-toxic EPAC1 activators.

Summary: The next-generation PARPi thioparib shows strong antitumor activity against PARPi-sensitive and -resistant HR-deficient cells, inducing DNA damage, replication stress, cell cycle arrest, and apoptosis. It also inhibits HR-mediated DNA repair, activates STAT1 and induces type I interferon production, leading to tumor growth inhibition.
