Estimating costs of ecological restoration across degradation scenarios in South Brazilian grasslands

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Grassland ecosystems are among the most threatened worldwide, and the Campos Sulinos—a region of subtropical grasslands in southern Brazil—experiences degradation driven by multiple factors. This study provides initial cost estimates for different restoration approaches, offering guidance for technical and budgetary planning ...

The Araucaria Project. The Distance to the Sculptor dwarf spheroidal galaxy from infrared photometry of RR Lyrae stars

open access: yes, 2008
We have obtained single-phase near-infrared magnitudes in the J and K bands for a sample of 78 RR Lyrae stars in the Sculptor dSph galaxy. Applying different theoretical and empirical calibrations of the period-luminosity-metallicity relation for RR ...

Matchmaking: a meta‐analysis of plant growth‐promoting microbial partnerships driving tree seedling performance in the Atlantic Forest biome

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction The Brazilian Atlantic Forest (BAF) is a biodiversity hotspot, and inoculating native seedlings with plant growth‐promoting microorganisms (PGPMs) may enhance seedling vigor for forest restoration. Objectives We performed a meta‐analysis to evaluate the effects of PGPMs on BAF seedlings and identify strategies to optimize ...

Effects of management practices on water yield in small headwater catchments at Cordillera de los Andes in southern Chile [PDF]

open access: yes, 2009
In several parts of the world, drinking water is obtained from springs in natural and managed mountainous forests. Since forests regulate quality as well as quantity of water, the effects of forest-management activities on water yield are an important ...
