Bulbophyllum weddellii (Orchidaceae) demonstrates foliar water uptake plasticity along Brazilian campos rupestres

open access: yesNordic Journal of Botany, EarlyView.
Phenotypic plasticity can facilitate species survival in a variety of conditions that are not possible with a fixed phenotype. Foliar water uptake (FWU), defined as the absorption of water through leaf surfaces, is an important mechanism contributing to plant water balance and drought tolerance in many species.

Restoring a Disappearing Ecosystem: the Longleaf Pine Savanna [PDF]

open access: yes, 2013
Longleaf pine (Pinus palustris) savannas of the southeastern United States contain some of the worlds most diverse plant communities, along with a unique complement of wildlife. Their traditionally open canopy structure and rich understory of grasses and herbs were critical to their vigor.

Pre-European fire regimes in Australian ecosystems [PDF]

open access: yes, 2008
We use multiple lines of evidence, including palaeo-environmental, ecological, historical, anthropological and archaeological, to investigate pre-European fire regimes in Australia, with particular focus on the extent to which the use of fire by ...

Brazil seed transfer zones: Supporting seed sourcing for climate‐resilient ecosystem restoration

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Brazil has tens of millions of hectares of degraded land that must be restored to meet national and global biodiversity and climate goals. Sowing genetically diverse native seeds is key to restoring degraded lands to climate‐resilient landscapes, but we still lack guidance on how to effectively match seed sources to restoration sites across broad ...

Environmental changes during the last millennium based on multi-proxy palaeoecological records in a savanna-forest mosaic from the northernmost Brazilian Amazon region

open access: yesAnais da Academia Brasileira de Ciências, 2015
The environmental changes and the dynamics of the savanna-forest mosaic, over the last 1050 years, have been reconstructed by pollen, charcoal, radiocarbon dating mineralogical and geochemical analyses of sediment cores taken from three different ...

Beyond forests: Harnessing conservation gardening for open biomes in Brazil

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Urban gardening offers an innovative conservation strategy by integrating native ornamental species into urban landscapes. We evaluated the ornamental potential of the Brazilian flora by comparing the representation of species from forests versus open biomes (focusing on campo rupestre grasslands) and introduced and validated the Index of Ornamental ...

Characterizing Savanna Tree Canopy Heights Using GEDI and Spatially Continuous Multi-Source Data at a Landscape Level

open access: yesRemote Sensing
Accurately mapping tree canopy heights of savanna ecosystems, which account for around 20% of the terrestrial land surface, is of great importance for global biomass estimation, carbon cycling, and biodiversity.

Peri‐urban agroforestry for climate mitigation in West Africa: Structural diversity and functional traits as key drivers of carbon storage

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Peri‐urban areas in West Africa are expanding rapidly, often with limited planning and growing exposure to climate risks. Our study shows that agroforestry systems in these landscapes, especially diverse home gardens, can store substantial amounts of carbon when they include structurally complex stands and species with traits that favor biomass ...

Ecosystem Processes and Dynamics in Mesic Savannas

open access: yes, 2023
AbstractAn introduction is presented to systems ecology, through models of the pathways, pools and fluxes of materials in terrestrial ecosystems, and the role of feedback mechanisms, and of the first and second laws of thermodynamics. Food chains, food webs and trophic levels provide structure to ecosystem processes.

Spatial Pattern Enhances Ecosystem Functioning in an African Savanna

open access: yesPLoS Biology, 2010
إن اكتشاف أن الأنماط المكانية المنتظمة يمكن أن تظهر في الطبيعة من التفاعلات المحلية بين الكائنات الحية قد دفع إلى البحث عن الأهمية البيئية لهذه الأنماط. توقعت النماذج النظرية أن يكون للنمط آثار إيجابية ناشئة على وظائف النظام الإيكولوجي الأساسية، مثل الإنتاجية. نحن نقدم الدعم التجريبي لهذا التنبؤ. في النظم الإيكولوجية للأراضي الجافة، غالبًا ما تكون تلال
