Vast, overlooked peat, and organic soils in Brazil's Cerrado: carbon storage, dynamics, and stability
Introduction Carbon is a critical element on Earth, underpinning life and contributing to global warming via greenhouse gas emissions. Understanding its distribution and turnover is therefore critical (IPCC et al., 2022). Soils represent the largest terrestrial organic carbon reservoir, storing more carbon than the atmosphere and vegetation combined, and therefore play a pivotal role in the global carbon budget (Scharlemann et al., 2014; Köchy et al., 2015).
The endomicrobiome and weed invasiveness in Mediterranean ecosystems worldwide - Nature Communications
|
Abstract Mediterranean ecosystems, one of the most significant global hotspots of biodiversity, are threatened by invasive weeds. Although endomicrobiomes – the vast array of microbes colonising living plant tissues – are known to affect plant fitness, their contribution to weed invasiveness remains virtually unknown. Here, we experimentally assess the role of the endomicrobiome in the invasiveness of Taraxacum officinale (common dandelion), a widespread weed in Mediterranean ecosystems worldwide.

Beyond species means - the intraspecific contribution to global wood density variation
Content Summary 4 I. Introduction 4 II. Materials and Methods 6 III. Results 9 IV. Discussion 12 Acknowledgements 17 References 19 I. Introduction Wood density, the oven-dry mass of wood (g) over its fresh volume (cm−3), is an important plant functional trait in ecology and global change studies. Accurate species-level averages of wood density are needed for unbiased estimation of aboveground carbon in vegetation (Phillips et al., 2019).
The Influence of Dominant Habitats on Termite Species Diversity and Community Structure in the Brazilian Savanna
1 Introduction Species distributions vary across space due to differences in environments and biogeographic history, and these patterns may differ at various spatial scales. For example, termites are known to strongly respond to latitude gradients due to changes in temperature and precipitation, which influence their distribution (Cancello et al. 2014; Wijas et al. 2022).
Biomass production of tropical trees across space and time: The shifting roles of diameter growth and wood density
1 INTRODUCTION Tropical forests are essential to the global carbon cycle, accounting for two-thirds of the terrestrial woody biomass (Pan et al., 2013) and more than half of the world's aboveground forest carbon (Pan et al., 2024). Trees store ~40%–50% of carbon in their dry biomass across their lifespan (Martin & Thomas, 2011), serving as long-term carbon reservoirs (Köhl et al., 2017).

Symbiotic status alters fungal eco‐evolutionary offspring trajectories
Phylogenetic regression of shifts in spore size and evolutionary transitions in symbiotic groups Because evolutionary history shapes how and where species are today, the role of this history can be examined by testing how traits shift across the tree of life. For fungal spores, recent reviews and anecdotal evidence suggest that spore size is expected to differ more widely in some fungal clades than others (Aguilar-Trigueros et al., 2019; Ingold, 2001).
Beyond the usual climate? Factors determining flowering and fruiting phenology across a genus over 117 years
Earlier plant reproduction has been well documented in response to climate change (Menzel et al., 2006; Parmesan, 2006; Miller-Rushing and Primack, 2008; Ganjurjav et al., 2020), with some species advancing phenology by up to 2.5 days per °C over 30 years (Menzel et al., 2006). Climate cues contribute significantly toward phenological variance.
Climate change could make one household pest increase its path of destruction
When we consider termites, we may think of the danger they can pose to our houses once they settle in and start eating wood. But in fact, only about 4 percent of termite species worldwide are considered pests that might, at some point, eat your house. In nature, wood-eating termites play a broad and important role in warm tropical and sub-tropical ecosystems. In feeding on wood, they recycle essential nutrients from the soil and release carbon back into the atmosphere.

Coevolutionary legacies for plant decomposition
Highlights Plant litter decomposition adds a different process and ecological context to the coevolution literature, which has thus far focused on the ecology of symbionts during their lifetimes. This context integrates the literature on how arms races between plants and their consumers (herbivores, pathogens) or mutualists (nitrogen-fixing bacteria, mycorrhizal fungi) drive the quality of plant tissue, with an important legacy for litter decomposability.
Three keys to the radiation of angiosperms into freezing environments
Abstract Early flowering plants are thought to have been woody species restricted to warm habitats1,2,3. This lineage has since radiated into almost every climate, with manifold growth forms4. As angiosperms spread and climate changed, they evolved mechanisms to cope with episodic freezing.
What we (don't) know about global plant diversity
AbstractRationale: The era of big biodiversity data has led to rapid, exciting advances in theoretical and applied biological, ecological and conservation sciences. While large genetic, geographic and trait databases are available, these are neither complete nor random samples of the globe. Biases in species absence in these databases create problems, reducing our inferential and predictive power.
