Abstract Aim Large trees (d.b.h. ≥ 70 cm) store large amounts of biomass. Several studies suggest that may be vulnerable to changing climate, potentially leading declining forest biomass storage. Here we determine the importance for tropical storage and explore which intrinsic (species trait) extrinsic (environment) variables are associated with density at continental pan‐tropical scales. Location Pan‐tropical. Methods Aboveground ( AGB) was calculated 120 intact lowland moist locations....
In urban environments, green roofs provide a number of benefits, including decreased heat island effects and reduced energy costs for buildings. However, little research has been done on the non-plant biota associated with roofs, which likely affect their functionality. For current study, we evaluated whether or not planted two native plant communities in New York City functioned as habitats soil fungal communities, compared roof growing media to microbial composition five city parks,...
Most tropical rain forests contain diverse arrays of tree species that form arbuscular mycorrhizae. In contrast, the less common monodominant forests, in which one comprises more than 50% canopy, frequently ectomycorrhizal (ECM) associates. this study, I explored potential for ECM networks, created by aggregations trees, to enhance seedling survivorship near parent trees. determined benefit conferred network on growth and an Guyana. Seedlings with access had greater (73% greater), leaf...
Fungi influence nutrient cycling in terrestrial ecosystems, as they are major regulators of decomposition and soil respiration. However, little is known about the substrate preferences individual fungal species outside laboratory culture studies. If active fungi differ their situ, then changes diversity due to global change may dramatically ecosystems. To test responses taxa specific substrates, we used a nucleotide-analogue procedure boreal forest Alaska (USA). Specifically, added four...
Plants interact with a diversity of microorganisms, and there is often concordance in their community structures. Because most community-level studies are observational, it unclear if such arises because host specificity, which microorganisms or plants limit each other's occurrence. Using reciprocal transplant experiment, we tested the hypothesis that specificity between trees ectomycorrhizal fungi determines patterns tree fungal soil specialisation. Seedlings 13 dipterocarp species...
Phosphorus (P) is an essential nutrient that often in limited supply, with P availability constraining biomass production many terrestrial ecosystems. Despite decades of work on plant responses to deficiency and the importance soil microbes ecosystem processes, how respond to, cope with, deficiencies remains poorly understood. We studied 583 soils from two independent sample sets each span broad natural gradients extractable collectively represent diverse biomes, including tropical forests,...
Abstract Although fungal communities are known to vary along latitudinal gradients, mechanisms underlying this pattern not well‐understood. We used high‐throughput sequencing examine the large‐scale distributions of soil fungi and their relation evolutionary history. tested Tropical Conservatism Hypothesis, which predicts that ancestral groups should be more restricted tropical latitudes conditions than would recently derived groups. found support for hypothesis in older phyla preferred...
Significance Bacterial natural products (NPs) have served as inspiration for many therapeutics. The hunt new bioactive NPs has led to a global search ecosystems from which bacteria can be cultured. Here, we used NP-focused metagenome sequencing explore biosynthetic diversity in urban park soil of New York City. Our analyses reveal rich these microbiomes and predict that gene clusters encoding clinically approved families discovered using cultured around the world are actually present single...
One mechanism proposed to explain high species diversity in tropical systems is strong negative conspecific density dependence (CDD), which reduces recruitment of juveniles proximity adult plants. Although evidence shows that plant-specific soil pathogens can drive CDD, trees also form key mutualisms with mycorrhizal fungi, may counteract these effects. Across 43 large-scale forest plots worldwide, we tested whether ectomycorrhizal tree exhibit weaker CDD than arbuscular species. We further...
Abstract According to the Intergovernmental Panel on Climate Change (IPCC), agriculture is responsible for 10-12% of total global anthropogenic emissions and almost a quarter continuing increase greenhouse gas (GHG) emissions. Not all forms agriculture, however, have equivalent impacts warming. Industrial contributes significantly warming, representing large majority agriculture-related GHG Alternatively, ecologically based methods agricultural production, predominantly used small-scale...
Fungi regulate key nutrient cycling processes in many forest ecosystems, but their diversity and distribution within across ecosystems are poorly understood. Here, we examine the spatial of fungi a boreal tropical ecosystem, focusing on ectomycorrhizal fungi. We analyzed fungal community composition litter (organic horizons) underlying soil horizons (0–20 cm) using 454 pyrosequencing clone library sequencing. In both forests, found significant clustering communities by site with analogous...
Our understanding of the long-lasting effects human land use on soil fungal communities in tropical forests is limited. Yet, over 70% all remaining are growing former agricultural or logged areas. We investigated relationship among history, biotic and abiotic factors, community composition diversity a second-growth forest Puerto Rico. coupled high-throughput DNA sequencing with tree environmental data to determine whether history had an effect descriptors. also factors that underlie such...
The underrepresentation of women in science has received significant attention. However, there have been few studies which longitudinal data were used to assess changes over time. Here, we surveyed the Organization for Tropical Studies graduate database, because this database was also 1988, determine challenges still faced by ecologists. Certain aspects women's situations shown substantial improvement since such as an increased number female colleagues, more-equal sharing childcare and...
