Ichthyofauna of the Mata de Itamacaoca, an urban protected area from the upper Munim River basin, Northern Brazilian Cerrado
(2020)The Munim River basin is one of the main river drainages of the Hydrological unit Maranhão, but there are few published studies which focus on ichthyological surveys and taxonomic work within this basin. The present study ... -
Identifying barriers to effective management of widespread invasive alien trees: Prosopis species (mesquite) in South Africa as a case study.
(Elsevier Ltd, 2016)Biological invasions are a major driver of ecological and social change globally. The negative effects of these invasions have led to the initiation of programs to manage these invasions across the world. Management aims ... -
Identifying knowledge gaps in the research and management of invasive species in India
(2019)India, a megadiverse tropical country is grappling with the issue of biological invasions. As a signatory to the Convention on Biological Diversity, India is committed for managing its major biological invasions by 2020. ... -
Impact of anthropogenic transportation to Antarctica on alien seed viability
(Springer-Verlag, 2010-04-27)Antarctic ecosystems are at risk from the introduction of invasive species. The first step in the process of invasion is the transportation of alien species to Antarctic in a viable state. However, the effect of longdistance ... -
The impact of invasive aquatic plants on ecosystem services and human well-being in Wular Lake, India
(Springer, 2018)Alien invasive species cause significant impacts on ecosystems and economies, but the impacts on human well-being and livelihoods are less well known. Negative impacts can be particularly severe when caused by floating ... -
Impacts of Carpobrotus edulis (L.) N.E.Br. on the germination, establishment and survival of native plants: A clue for assessing its competitive strength
(Public Library of Science, 2014-09-11)Does Carpobrotus edulis have an impact on native plants? How do C. edulis’ soil residual effects affect the maintenance of native populations? What is the extent of interspecific competition in its invasion process? In ... -
Insect diversity in Cape fynbos and neighbouring South African vegetation
(Blackwell Publishing Ltd, 2006)Aim It has often been suggested that South Africa’s Cape fynbos shrublands, although extremely rich in plant species, are poor in insects, thus representing a notable exception from the broad plant–insect diversity ... -
Insect thermal tolerance: what is the role of ontogeny, ageing and senescence?
(Cambridge Philosophical Society, 2008)Temperature has dramatic evolutionary fitness consequences and is therefore a major factor determining the geographic distribution and abundance of ectotherms. However, the role that age might have on insect thermal tolerance ... -
Inter-specific competitive stress does not affect the magnitude of inbreeding depression
(Yvonne Willi, 2007)Hypothesis: Stressful inter-specific competition enhances inbreeding depression. Organisms: Creeping spearwort (Ranunculus reptans L.) and its common competitor, the creeping bentgrass (Agrostis stolonifera L.). Field ... -
Interactions among multiple invasive animals
(Ecological Society of America, 2015)With accelerating rates of invasion being documented in many ecosystems, communities of interacting invasive species are becoming increasingly common. Opposing theories predict that invaders can either hinder or promote ... -
Intra- and interspecific hybridization in invasive Siberian elm
(Springer, 2017)Hybridization creates unique allele combinations which can facilitate the evolution of invasiveness. Frequent interspecific hybridization between the Siberian elm, Ulmus pumila, and native elm species has been detected ... -
Intransitive competition and its effects on community functional diversity
(Nordic Society Oikos, 2017)Can competitive interactions be inferred from the analysis of community functional diversity patterns? Originally, at the scale of a community, competitive interactions were supposed to generate trait overdispersion ... -
Introduction to the special issue: Tree invasions: towards a better understanding of their complex evolutionary dynamics
(Oxford University Press, 2017)Many invasive plants show evidence of trait-based evolutionary change, but these remain largely unexplored for invasive trees. The increasing number of invasive trees and their tremendous impacts worldwide, however, illustrates ... -
Invasive alien plants infiltrate bird-mediated shrub nucleation processes in arid savanna
(Blackwell, 2007)1 The cultivation and dissemination of alien ornamental plants increases their potential to invade. More specifically, species with bird-dispersed seeds can potentially infiltrate natural nucleation processes in ... -
Invasive crayfish threaten Okavango Delta
(The Ecological Society of America, 2016) -
Invasive plants threaten the least mobile butterflies in Switzerland
(John Wiley & Sons Ltd, 2017)Aim Biological invasions are today the second-largest global threat for biodiversity. Once introduced, exotic plant species can modify ecosystem composition, structure and dynamics, eventually driving native species to ... -
Is spinelessness a stable character in cactus pear cultivars? Implications for invasiveness
(Elsevier Ltd, 2019)Selection against invasiveness allows breeders to continue trading with plant cultivars when the wild species is otherwise invasive. However, to ensure the benefits of a species over the medium-to longer-term, it is necessary ... -
Is thermal limitation the primary driver of elevational distributions? Not for montane rainforest ants in the Australian Wet Tropics
(Springer, 2018)Terrestrial ectotherms are likely to be especially sensitive to rising temperatures over coming decades. Thermal limits are used to measure climatic tolerances that potentially affect ectotherm distribution. While there ... -
Karoo road verge study: Plot level sample data
(2008-07-04)File belonging to Kalwij et al 2008. This is a multivariate dataset at the plot level (n=240) whereby the Braun-Blanquet cover estimation of exotic species is listed for each plot. In addition a sheet with environmental ...
