ABSTRACT The lack of soil data is a complication that most soil scientists will encounter throughout their career; this critical aspect is exacerbated due to the excessive cost of soil surveying. Consequently, it is essential to develop strategies that guarantee the permanent accessibility of past soil sampling efforts.

Our results emphasize the necessity of considering the complex influences of grazing intensity on diversity and stability at different spatial scales for the effective management of Andean grasslands. Abstract Intensive land use and changing environmental conditions are reshaping the biodiversity, functioning and stability of local Andean grassland ...

We explored the allocation strategies of N and P in leaves and fine roots (metabolic organs) and, in stems and coarse roots (woody organs) of nine dominant tree species in secondary tropical dry forests using scaling analysis. The scaling relationships of P versus N concentrations in non‐leaf organs were isometric across secondary succession and ...

Island restoration to rebuild seabird populations and amplify coral reef functioning
Abstract Mobile organisms like seabirds can provide important nutrient flows between ecosystems, but this connectivity has been interrupted by the degradation of island ecosystems. Island restoration (via invasive species eradications and the restoration of native vegetation) can reestablish seabird populations and their nutrient transfers between ...

Abstract Nearshore seagrass, kelp, and other macroalgae beds (submerged aquatic vegetation [SAV]) are productive and important ecosystems. Mitigating anthropogenic impacts on these habitats requires tools to quantify their ecological value and the debits and credits of impact and mitigation.

The authors explored how insularity influences herbivory in oaks across island–mainland sites. By experimentally excluding vertebrate predators (e.g. birds, bats) and measuring leaf traits (e.g. phenolics, specific leaf area, nutrients), they provide insights into the mechanisms driving island–mainland herbivory patterns.

Ectomycorrhizal fungi and the nitrogen economy of Nothofagus in southern Patagonia
Ectomycorrhizal fungi play essential roles in nitrogen cycling and plant nutrient uptake at high latitudes. However, they have disproportionately been studied in boreal forests dominated by evergreen conifers. We characterized ectomycorrhizal associations and the nitrogen economy of co‐occurring deciduous and evergreen angiosperms from the genus ...
