Invasion ecology has much advanced since its early beginnings. Nevertheless, explanation, prediction, and management of biological invasions remain difficult. We argue that progress in invasion research can be accelerated by, first, pointing out difficulties this field is currently facing and, second, looking for measures to overcome them. We see basic and applied research in invasion ecology confronted with difficulties arising from (A) societal issues, e.g., disparate perceptions of invasive species; (B) the peculiarity of the invasion process, e.g., its complexity and context dependency; and (C) the scientific methodology, e.g., imprecise hypotheses. To overcome these difficulties, we propose three key measures: (1) a checklist for definitions to encourage explicit definitions; (2) implementation of a hierarchy of hypotheses (HoH), where general hypotheses branch into specific and precisely testable hypotheses; and (3) platforms for improved communication. These measures may significantly increase conceptual clarity and enhance communication, thus advancing invasion ecology.

“…Plants were divided into root, stem and leaf, dried at 80°C for 24 hours and weighed to evaluate their biomass. Specific leaf area (SLA), leaf area ratio (LAR), leaf area/root mass ratio (LA/RM), root mass ratio (RMR), stem mass ratio (SMR) leaf mass ratio (LMR) and absolute growth rate (AGR) and relative growth rate (RGR) were then calculated (POORTER; WERF, 1998;POORTER, 1999).…”

“…Invasive plants direct and indirect impact ecosystems (WEIDENHAMER;CALLAWAY, 2010) and the analysis of different abiotic factors such as light, temperature and water availability that interfere with the invasiveness of new areas triggers to in-depth knowledge on the invasion process (THEOHARIDES; DUKES, 2007;GUREVITCH et al, 2008) and on the risks of new invasions. In general, environments with more resources, such as water, light and nutrients, are more prone to invasion (DAVIS et al, 2000).…”

“…The Caatinga is a deciduous forest of the Brazilian Northeastern semiarid region, plants shed off their old foliage during the dry season, whilst new growth begins at the start of the rainy season, causing variations in light availability (BARBOSA, 2003). Studies on deciduous forest species under different shading conditions demonstrate that light does not affect the species survival, but it affects their growth, biomass allocation and physiological responses (PHONGUODUME et al, 2012;FERREIRA et al, 2012).…”

“…Therefore, they respond better than some native species in places with greater light supply (GUREVITCH et al, 2008). The ability to adapt to changes in the resource supply is associated with phenotypic plasticity (FUNK, 2008), which is an important strategy that increases invasiveness and allows invasive species to colonize different environments (GODOY et al, 2012;ZENNI et al, 2014).…”

ABSTRACT. The invasion by Cryptostegia madagascariensis causes economic and environmental problems in Northeastern Brazil. Current study evaluates the initial growth of C. madagascariensis on light gradient. The experiment used 0, 30, 50 and 70% shading treatments arranged in a completely randomized design and evaluated in four periods, namely, 35, 50, 65 and 80 days. Height, absolute growth rate, relative growth rate, number of side branches, number of leaves, leaf area, specific leaf area, leaf area ratio, root mass ratio, stem mass ratio, leaf mass ratio and leaf area/root mass ratio were evaluated. Results showed that the height was greater in shade environments, and the greater the available light, the greater was the number of side branches. C. madagascariensis is able to change the leaf area, specific leaf area and biomass allocation in different shadings. Since C. madagascariensis varies growth forms and performs morphological adjustments to increase light uptake, the plant has warranted success during the initial growth under different shadings.Keywords: functional traits, Caatinga, shading, morphological adjustments, biomass. Influência da luz no crescimento inicial da invasora Cryptostegia madagascariensis Bojer no semiárido Brasileiro RESUMO.A invasão da Cryptostegia madagascariensis causa problemas econômicos e ambientais no Nordeste do Brasil. O objetivo do trabalho foi estudar o crescimento inicial da C. madagascariensis em gradiente de luz. O experimento utilizou os tratamentos de 0, 30, 50 e 70% de sombreamento, dispostos em um delineamento experimental inteiramente casualizado e avaliados em quatro períodos: 35, 50, 65 e 80 dias. Foram avaliados a altura, a taxa de crescimento absoluto, a taxa de crescimento relativo, o número de ramos laterais e de folhas, a área foliar, a área foliar específica, a razão de área foliar, a razão de massa da raiz, a razão de massa do caule, a razão de massa das folhas e a razão área foliar/massa da raiz. Os resultados mostraram que a altura foi maior em ambientes sombreados e, quanto mais luz disponível, maior o número de ramos laterais. A C. madagascariensis é capaz de alterar a área foliar, a área foliar específica e na alocação de biomassa nos diferentes sombreamentos. Portanto, a C. madagascariensis varia a forma de crescimento e realiza ajustes morfológicos para aumentar a captação de luz, o que garantiu seu sucesso durante o crescimento inicial em diferentes sombreamentos.

Historic land use influences contemporary establishment of invasive plant species

The legacy of agricultural land use can have widespread and persistent effects on contemporary landscapes. Although agriculture can lead to persistent changes in soil characteristics and plant communities, it remains unclear whether historic agricultural land use can alter the likelihood of contemporary biological invasions. To understand how agricultural land-use history might interact with well-known drivers of invasion, we conducted factorial manipulations of soil disturbance and resource additions within non-agricultural remnant sites and post-agricultural sites invaded by two non-native Lespedeza species. Our results reveal that variation in invader success can depend on the interplay of historic land use and contemporary processes: for both Lespedeza species, establishment was greater in remnant sites, but soil disturbance enhanced establishment irrespective of land-use history, demonstrating that contemporary processes can help to overcome legacy constraints on invader success. In contrast, additions of resources known to facilitate seedling recruitment (N and water) reduced invader establishment in post-agricultural but not in remnant sites, providing evidence that interactions between historic and contemporary processes can also limit invader success. Our findings thus illustrate that a consideration of historic land use may help to clarify the often contingent responses of invasive plants to known determinants of invasibility. Moreover, in finding significantly greater soil compaction at post-agricultural sites, our study provides a putative mechanism for historic land-use effects on contemporary invasive plant establishment. Our work suggests that an understanding of invasion dynamics requires knowledge of anthropogenic events that often occur decades before the introduction of invasive propagules.
