There is growing recognition that classifying terrestrial plant species on the basis of their function (into 'functional types') rather than higher taxonomic identity, a promising way forward for tackling important ecological questions at scale ecosystems, landscapes or biomes. These include those vegetation responses to and effects on, environmental changes (e.g. in climate, atmospheric chemistry, land use other disturbances). also consensus about shortlist traits should underlie such...
Plant functional traits are the features (morphological, physiological, phenological) that represent ecological strategies and determine how plants respond to environmental factors, affect other trophic levels influence ecosystem properties. Variation in plant traits, trait syndromes, has proven useful for tackling many important questions at a range of scales, giving rise demand standardised ways measure ecologically meaningful traits. This line research been among most fruitful avenues...
• Associations between specific leaf area (SLA), water content (LWC) and thickness (LT) in 77 species were analysed to identify which of these traits gave a better indicator value general plant resource-use strategy within the flora central-western Argentina, succulent are common. When all considered together, SLA LWC not significantly correlated. All high-SLA tender-leafed showed high LWC. Low SLA, however, was associated both with low (sclerophyllous species) (succulents). succulents...
Abstract Despite the vast diversity and complexity of herbivores, plants their interactions, most authors agree that a small number components leaf quality affect preference by generalist herbivores in predictable way. However, herbivore is determined not only intrinsic plant attributes biology but also environmental context. Within this framework, we aimed to analyse general interspecific trends association between herbivory traits over wide range angiosperms from central Argentina. We (i)...
Abstract Aim To determine how the distribution and cover of different vegetation types are affected by physical factors livestock in a mountain range with long evolutionary history grazing. Location Upper belt Córdoba mountains (1700–2800 m a.s.l., 31º34′ S, 64º50′ W) central Argentina. Methods Using GIS, we analysed relationships plant to features (physiography topography) indicators accumulated pressure (distance human settlements roads) through multinomial logistic regression. We...
Question: Is the response of plant traits to environment at community level similar when considering species abundance and presence only? Location: Mountain grasslands, central Argentina. Methods: We used data from 57 floristic samples, ordinated through DCCA along moisture grazing gradients combined with trait values 85 (plant height, leaf area, thickness toughness SLA). For each sample, we calculated weighted average (considering abundance) simple only presence). Through multiple...
Abstract Questions Most vegetation descriptions tacitly assume that floristic composition and physiognomy are tightly linked. However, the two properties may not respond in a similar way to environmental disturbance gradients, leading uninformed management planning difficulties when attempting restore degraded ecosystems. In this context, we addressed main questions: (1) how close relations between physiognomic types as defined by numerical classification mountain ecosystems; (2) distributed...
Abstract Fire frequency has been highlighted as an important component of fire effects on ecosystems; nevertheless, there is scarce information about how modulates changes in ecosystem properties, particularly for subtropical dry forests. A long‐term natural experiment and a multiscale approach were used to analyze properties forest subjected contrasting regimes. Measurements taken two adjacent sites that had regimes (low/high frequency), vegetation soil analyses combined with...
Abstract: Positive interactions between species are known to play an important role in the dynamics of plant communities, including enhancement invasions by exotics. We studied influence invasive shrub Pyracantha angustifolia (Rosaceae) on recruitment native and exotic woody a secondary shrubland central Argentina mountains. recorded sapling micro‐environmental conditions under canopies dominant Condalia montana (Rhamnaceae), absence cover, considering these situations as three treatments....
Summary 1. Dominant plant functional types (PFTs) are expected to be primary determinants of communities other above‐ and below‐ground organisms. Here, we report the effects experimental removal different PFTs on arbuscular mycorrhizal fungi (AMF) in a shrubland ecosystem central Argentina. 2. On basis biomass‐ratio hypothesis resource use strategy theory, effect AMF colonization spores proportional biomass removed stronger when more conservative were removed. The treatments applied were:...
Abstract Seed size is one of the most important traits in regenerative phase a plant's life cycle; however, for cactus species relationship seed and germination characteristics seedling still unclear. We studied between mass 17 from central Argentina, belonging to different genera forms. measured mass, total germination, light requirements mean time these cacti species; addition, we recorded shape 15 species. To test performed experiments under laboratory conditions at 25/15°C (day/night...
Abstract Sprouting vigour is determined by the plant amount of reserves and intrinsic growth rate plants. While first factor has been well studied, second far less understood. Although a higher would imply sprouting vigour, fast‐growing species may have below‐ground reserves, thus, lower potential. The relative importance both opposite effects was little explored in literature. To analyse influence on one season after fire we measured height old (pre‐fire) new (post‐fire) tissue 194...
The invasion of a target community by non‐indigenous plant species includes the stages arrival, establishment and spread, which tend to depend on different characteristics invasive its context. While mechanisms behind highly disturbed ecosystems are well known, our understanding process in undisturbed or weakly is much more limited. Here we propose that, once has arrived new ecosystem become established, likelihood that it spreads, thus becomes invasive, may just one very few...
