Resistência inicial de quatro espécies arbóreas em diferentes espaçamentos após ocorrência de geada Initial resistance of four arboreal species in different spacing after frost occurrence

Ciência Rural, 2011
A ocorrência de geada, dependendo do grau de dano, pode se tornar um fator limitante para a condução de florestas de curta rotação. O presente trabalho teve como objetivo avaliar o comportamento após ocorrências de geadas das espécies florestais Acacia ...

Hypsometrical Relation for Acacia mearnsii with Different Ages

, 2002
This work had as objective to select mathematical models to predict the height of trees in function of DBH and age, in black wattle stands, Acacia mearnsii De Wild., in Southeastern region of the State of Rio Grande do Sul, Brazil. For the adjustment of the height data 19 mathematical equations were tested, being used arithmetic and logarithmic linear ...

Inhibitory mechanisms of Acacia mearnsii extracts on the growth of Microcystis aeruginosa

Water Science and Technology, 2015
Our previous work revealed that Acacia mearnsii extract can inhibit the growth of Microcystis aeruginosa, the common species forming toxic cyanobacterial blooms in eutrophic freshwater. In the present study, we demonstrated that this plant extract can significantly increase cell membrane permeability and Ca2+/Mg2+-ATPase activity on the membrane.

Antifouling capacity of substrate materials and their effects on settlement and post‐settlement survival of Acropora palmata and Orbicella faveolata

Restoration Ecology, EarlyView.
Abstract Introduction In coral reef restoration, sexual reproduction is a key methodology to enhance coral population recovery. However, post‐settlement survival remains a major bottleneck, as spat are particularly vulnerable to competition with fouling organisms.

Invasive plant species for compost production: Review of environmental and economic insights

Journal of Environmental Quality, Volume 55, Issue 4, July/August 2026.
Abstract Invasive plant species pose significant ecological and economic challenges, threatening biodiversity and altering soil properties, while conventional control methods are often costly and resource‐intensive. This review examines the potential of composting invasive plant biomass as a viable and sustainable alternative that aligns with circular ...

The Effects of Lantana camara L. on Soil Physicochemical Properties in the Eastern Cape Province of South Africa

African Journal of Ecology, Volume 64, Issue 5, July 2026.
ABSTRACT Lantana camara L. is an invasive alien plant species that is recognised globally due to its extensive distribution and negative impacts on species diversity and ecosystem dynamics. Despite its extensive distribution in South Africa, its physicochemical impacts on soils are understudied. This study investigated the impacts of L.
