The Sustainability of Robusta Coffee Under Global Change—A Review

open access: yesSustainable Development, EarlyView.
ABSTRACT This contribution reviews the scientific evidence concerning climate resiliency claims as well as sustainability issues for robusta coffee (Coffea canephora), focusing on: climate change analyses, climate parameters, soil water, and farming inputs, especially irrigation and synthetic fertilizer use.

Underground Baristas: ecology of mycorrhizal fungi in Cerrado coffee cultivation

open access: yesScientific Reports
The symbiosis between arbuscular mycorrhizal fungi (AMF) and coffee plants can improve nutrient use and crop resilience in low-fertility tropical soils.

Ecosystem services from tropical savannas: economic opportunities through payments for environmental services

open access: yes, 2009
Economic activity in the tropical savannas of northern Australia, like rangeland regions across the globe, has traditionally been based on primary production – predominantly cattle grazing and mining. More recently, northern Australia has experienced an

Antimicrobial Residues in a Key Cerrado River: Distribution, Persistence, and Effects on Zebrafish Embryo‐Larval Development

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The current study aimed to quantify the antimicrobials amoxicillin (AMX), cefazolin (CFZ), chloramphenicol (CHL), metronidazole (MTZ), and sulfamethoxazole (SX) in effluents and surface water of an important Cerrado river, calculate their half‐lives, and analyze their ecotoxicity following single and combined exposures.

Perturbations in the carbon budget of the tropics [PDF]

open access: yes, 2014
The carbon budget of the tropics has been perturbed as a result of human influences. Here, we attempt to construct a ‘bottom-up’ analysis of the biological components of the budget as they are affected by human activities.

Varying hydraulic strategies within leaves, stems and roots of coexisting desert shrubs

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Effective and continuous root‐to‐leaf hydraulic transport is crucial for plant survival and growth during drought. However, the capacity to resist hydraulic dysfunction remains understudied in leaves and roots, especially for desert shrubs.

Bat community assembly in the ecotone of two neotropical biodiversity hotspots is determined by environmental filtering rather than historical factors

open access: yesJournal of Animal Ecology, EarlyView.
We demonstrate that environmental filtering is the primary mechanism shaping bat communities across the Cerrado–Atlantic Forest ecotone. By integrating phylogenetic diversity, environmental gradients, and coevolutionary assembly models, our study provides new insights into the processes maintaining biodiversity in a globally important transition zone ...

Bird species richness peaks at intermediate levels of farmland in wooded savannas and dry forests, but not in rainforests

open access: yesBasic and Applied Ecology
Despite widespread concern over farmland-driven biodiversity loss in tropical landscapes, the possibly non-linear response of species richness to farmland and the possible dependency of this response on biome remain poorly understood.

Carbon cycle processes in tropical savannas of far North Queensland, Australia [PDF]

open access: yes, 2017
Tropical savannas represent a diverse range of heterogenous ecosystems that play an important role in the global carbon cycle as they occupy approximately one fifth of the land surface.

Genomic Investigations Unveil the Genetic Underpinnings of Environmental Adaptation in African Goat Populations

open access: yesIntegrative Zoology, EarlyView.
This study integrates genomics and landscape genetics to analyze African goat environmental adaptation. Analyzing 1591 samples, it finds population structure differentiates geographically into four groups, with gene flow between wild Yura goats and North Africans.
