Summary: Censuses of seedlings in the permanent Forest Dynamics Plot on Barro Colorado Island, Panama were conducted between 2001 and 2018, resulting in a dataset of nearly 1 million observations of over 185,000 individuals of >400 tree, shrub, and liana species. These data will allow for spatially-explicit analyses of seedling distributions, recruitment, growth, and survival for hundreds of woody plant species.

Summary: This study aimed to understand the phylogenetic relationship between alien plant species at different stages of invasion and the influence of environmental filtering process on this relationship. The results showed that phylogenetically related species tend to cluster together at smaller spatial scales, indicating the importance of environmental filtering process. The presence of close relatives in the community may facilitate the successful naturalization and invasion of introduced alien species. Temperature has a stronger effect on phylogenetic patterns than precipitation, especially at smaller spatial scales. Different plant families showed different phylogenetic patterns, but all tend to form more clustered assemblages.

Summary: Studies focusing on relatively small spatial scales have shown that alien plants are more likely to invade phylogenetically clustered communities, and that the introduction of alien plants further increases phylogenetic clustering in the recipient communities. However, whether these patterns hold at a continental scale remains untested. Here, we investigate the phylogenetic structure of native and alien regional assemblages of angiosperms across North America.

Summary: The introduction of alien species in China's angiosperm assemblages can be influenced by the phylogenetic structure of the native species, while also altering that structure. The richness and phylogenetic structure of alien species show spatial patterns similar to native species, and are correlated with climatic factors. At broader phylogenetic scales, alien species tend to recapitulate the biogeographic patterns of natives, while at narrower scales, this pattern is less clear.

Summary: Most studies on terrestrial ecosystems have shown that non-native species are more likely to invade phylogenetically clustered communities. Our study found that non-native fish species tend to invade communities with lower phylogenetic dispersion and that the introduction of non-native species can both decrease and increase clustering in different watersheds. The results suggest that the phylogenetic diversity of the invaded assemblages plays a role in the support for Darwin's naturalization and preadaptation hypotheses.

Summary: Island floras are diverse and face severe threats. The vulnerability of island species to invasive plants and their ability to resist displacement remains unclear. The assumption that island plants have evolved conservative resource use, slow growth rates, and weak competitive abilities has mixed evidence. Future studies comparing functional strategies of native island and native continental plants, as well as tests for competition between native and invasive island plants, are urgently needed to protect these biodiversity hotspots.

Summary: Antagonistic seed predation networks in the tropics can be predicted based on plant phylogenetic distance and traits, with higher insect host specificity observed in Panama. Factors such as insect faunal composition, incidence of dry fruits, and plant traits influence network structure, highlighting the need to study both types of networks for forest conservation practices.

Summary: The niche variation hypothesis suggests that competition release allows populations to expand their ecological niche through individual specialization and expanding the niche of all individuals. Previous studies have provided strong evidence supporting this hypothesis when considering behavioral or ecological traits. This study aims to provide robust evidence for a significant and positive relationship between total niche width and individual specialization in amphibian populations at a global scale.

Summary: We analyzed population dynamics in Barro Colorado Island (Panama) using 35 years of census data and investigated whether the community is in a stationary state. Although individual species abundances showed large fluctuations, determining stationarity required distinguishing random fluctuations from actual trends. We argued that a species average is the best proxy for the unfeasible history average, and found that the population dynamics of BCI is stationary but not static, exhibiting fluctuations with a characteristic time of around 15 years, which is two orders of magnitude less than previously estimated.

Summary: Shifts between native and alien climatic niches pose challenges for predicting biological invasions, especially for insular species. This study analyzed alien occurrences of endemic insular amphibians, reptiles, and birds and found that climatic mismatches were common in invasions of birds and reptiles, but less common in amphibians. Several predictors were identified for climatic mismatches, which varied among taxonomic groups.

Summary: Vegetation phenology is highly sensitive to climate change. Using solar-induced chlorophyll fluorescence (SIF) and Normalized Difference Vegetation Index (NDVI), the study found similar spatial patterns in phenological states but different dates for key events. NDVI data overestimated the photosynthetic period in the extratropical Northern Hemisphere compared to CSIF data.

Summary: Despite progress in understanding global biodiversity loss, there are still taxonomic and geographic knowledge gaps. Decision makers often rely on expert judgement, but cannot engage with large and diverse groups of specialists. A survey of biodiversity experts worldwide revealed consensus and differences in perspectives and estimates, with underrepresented groups recommending different conservation priorities and providing higher estimates of biodiversity loss.

Summary: The relationship between biodiversity and ecosystem functions has been widely studied, but the variation in ecosystem functions across systems with similar species diversity has been rarely addressed. In this study, a food web model and empirical data were used to examine the relationships between species richness and variation in ecosystem functions. The results suggest that the variation in ecosystem functions is influenced by trophic interactions and the diversity of basal species, which has implications for biodiversity loss and ecosystem predictability.

Summary: Gradient and scale are two key concepts in ecology and evolution that can jointly influence eco-evo patterns. While scale refers to the dimensional space of a specific issue, gradient measures the range of a variable. However, the role of changing gradients has received relatively little attention compared to changing scales. Evaluating the role of scale in ecological patterns should be done in conjunction with considering the underlying environmental gradients, as the difference between sampled and potential gradients can profoundly impact observed patterns and alter scale-gradient relationships.

Summary: The 3D physical aspects of ecosystems are linked to ecological processes. Structural diversity, defined as the volumetric capacity, physical arrangement, and identity/traits of biotic components, has been overlooked due to a lack of theoretical foundation and measurement tools. A framework is proposed to conceptualize and incorporate structural diversity into ecological theory and practice, considering the interplay of genetic and environmental factors. A practical approach is suggested to test the ecological role of structural diversity and integrate it into ecological theory and management across scales.

Summary: This study investigates the response of soil nitrogen (N) concentrations and C:N ratios to afforestation in northern China and on a global scale. The results show that soil N status influences soil carbon (C) and N dynamics after afforestation. Afforestation increases soil C and N storages in N-poor soils but decreases them in N-rich soils. Changes in soil C:N ratios are mediated by the initial relative abundance of soil C and N, as well as the types of mycorrhiza associated with planted trees.

Summary: This study uses satellite data and tree-ring data to find that 70% of negative extreme anomalies in vegetation growth (NEGs) across the global land surface from 1981 to 2015 are attributed to five types of climate extremes and their combinations. The dominant climate extremes responsible for NEGs vary by region and biome. The findings have important implications for climate-specific disaster prevention and mitigation planning.

Summary: The authors found that early spring phenology slows drought recovery, while delayed spring phenology prolongs it. More than half of ecosystems in the mid- and high-latitudinal Northern Hemisphere fail to recover from extreme droughts within a single growing season. The phenology effects on drought recovery are comparable to or larger than other well-known postdrought climatic factors, suggesting the need to incorporate these interactions into Earth system models.

Summary: Using satellite data, we investigated the trends in foliar carbon accumulation and allocation during leaf green-up across the Northern Hemisphere from 2000 to 2017. Our results showed that there was an accelerated accumulation of foliar carbon in the early green-up period, driven by both increased photosynthesis and higher carbon allocation to leaves due to climate change. However, in the late stage of green-up, there were decreasing trends in foliar carbon accumulation and allocation. These stage-dependent trends are currently not represented in terrestrial biosphere models, highlighting the need for better incorporation of carbon allocation in these models.

Summary: This study develops a convolutional recurrent deep learning model to accurately predict fine-resolution spatiotemporal changes in grass coverage in arid regions. Applying the model to the Gobi Desert reveals that ecological flow regulation contributes to 61.8% of the total increase in grass cover over 2005-2015, nearly triple the contribution of local climate change. The study highlights the importance of timely, adaptive and spatially heterogeneous ecological flow management in addressing grassland degradation in arid regions and expands the understanding of the global greening process.

Summary: This study used satellite data to analyze the changes in tropical forests in mainland Southeast Asia. The results showed that during the period from 2000 to 2020, tropical forests gradually transformed into savannahs, and the reasons for this transformation varied in different time periods. In the early period, the increase in savannahs was mainly due to tree regeneration from grasslands, while in the recent period, the degradation of forests was the main cause. This study provides important references for land management and tropical forest protection.
