From a Lose–Lose to a Win–Win Situation: User-Friendly Biomass Models for Acaci...
Ulm, Florian; Estorninho, Mariana; Jesus, JG; de Sousa Prado, Miguel Goden; Cruz, Cristina; Máguas, C.Woody invasive species pose a big threat to ecosystems worldwide. Among them, Acacia longifolia is especially aggressive, fundamentally changing ecosystem structure through massive biomass input. This biomass is rarely harvested for usage; thus, these plants constitute a nuisance for stakeholders who invest time and money for control without monetary return. Simultaneously, there is an increased effort to valor...
Arbuscular mycorrhizal traits are good indicators of soil multifunctionality in...
Mahmoudi, Neji; Caeiro, Maria F.; Mahdhi, Mosbah; Tenreiro, Rogério; Ulm, Florian; Mars, Mohamed; Cruz, Cristina; Dias, TeresaDrylands are highly susceptible to degradation and climate change, which has important ecological and socio- economic consequences worldwide. To halt drylands degradation, plant species selection for restoration is starting to include also a functional approach, but does not integrate belowground functional traits yet. Therefore we tested the use of mycorrhizal traits to identify native plant species which host...
Ecological complexity effects on thermal signature of different Madeira island ...
Avelar, David; Garrett, Pedro; Ulm, Florian; Hobson, Peter; Penha-Lopes, GilFrom a systemic perspective, evolution and natural succession promote the creation of efficient biological structures and processes that capture and dissipate the solar energy, maximizing the entropy production. This ecological complexification results in better ecosystem thermodynamic performance indicated by lower tem- perature. In a brief period of evolutionary time human-induced disturbance has altered prof...
Impacts of acacia longifolia invasion on soil nutrient cycles : from invasion t...
Ulm, FlorianAnthropogenic alterations of nutrient cycles and the global redistribution of plant species have a profound impact on soils and the ecosystems relying on them. Invasive woody legumes can engineer oligotrophic ecosystems towards increased biomass production and nutrient turnover. This increased biomass is detrimental to native ecosystems, but could also be useful as a compost feedstock for agricultural purposes....
Early Acacia invasion in a sandy ecosystem enables shading mediated by soil, le...
Meira-Neto, João Augusto Alves; Silva, Maria Carolina Nunes Alves da; Tolentino, Gláucia Soares; Gastauer, Markus; Buttschardt, Tillmann; Ulm, FlorianAustralian species of the genus Acacia are amongst the most invasive trees. As nitrogen fixers, they are able to invade oligotrophic ecosystems and alter ecosystem functioning to their benefit. We aimed to answer three questions: How does early Acacia invasion influence nitrogen and light in a sandy savanna? How does early Acacia invasion impact biodiversity? Does early invasion alter ecosystem functioning towa...
