Article
Plant resistance includes mechanical and chemical defenses that reduce herbivory, while plant tolerance reduces the fitness impact of herbivory. Because defenses are costly and investing in both resistance and tolerance may be superfluous, trade‐offs among them are expected. In forest ecosystems, the mechanical strengthening of leaves is linked bot...

Phenotypic plasticity is a key mechanism by which plants respond to changing or heterogeneous conditions. Efforts to predict phenotypic plasticity across plant species have mainly focused on environmental variability or abiotic conditions, i.e. site characteristics. However, the considerable variation in phenotypic plasticity within sites calls for...
Article
Full-text available
Predicting plastic responses is crucial to assess plant species potential to adapt to climate change, but little is known about which factors drive the biogeographical patterns of phenotypic plasticity in plants. Theory predicts that climatic variability would select for increased phenotypic plasticity, whereas evidence indicates that stressful con...

Background and Aims Aridity is increasing in many regions of the world, but microclimatic conditions may buffer plant communities from the direct effects of decreased precipitation, creating habitat islands. However, reduced precipitation can also impact these communities indirectly by decreasing the suitability of the surrounding habitat, thus lim...
Article
Full-text available
Rapid local adaptation frequently occurs during the spread of invading species. It remains unclear, however, how consistent, and therefore potentially predictable, such patterns of local adaptation are. One approach to this question is to measure patterns of local differentiation in functional traits and plasticity levels in invasive species in mul...

Livestock production is an important activity in drylands. However, lack of adequate regulation of ranching activities can lead to the degradation of plant communities, which in turn can impact ecosystem functioning. In the arid ecosystems of north‐central Chile, unregulated goat grazing is widespread. Since the vegetation has a relatively short ev...

Premise of research. Tolerance to herbivory is the capacity of plants to reduce the negative effects of damage on fitness. Increased growth rate and photosynthesis are two important mechanisms behind tolerance to herbivory. The chlorophyll fluorescence parameter Fv =Fm, which reflects photosynthetic performance, has been used to characterize stress...
Article
Environmental gradients in alpine systems may lead to differences in both abiotic conditions and species interactions in very short distances. This may lead to reproductive and phenotypic changes in plants to enhance fitness in each environment. In this study, we explored how the Central Andean Viola maculata responds to the elevation gradient wher...
Article
The resource availability hypothesis (RAH), the most successful theory explaining plant defence patterns, predicts that defence investment is related to the relative growth rate (RGR) of plant species, which is associated with habitat quality. Thus, fast-growing species should show lower resistance than slow-growing species, which would lead fast g...

Background and aims: Disturbance often drives plant invasion and may modify community assembly. However, little is known about how these modifications of community patterns occur in terms of taxonomic, functional and phylogenetic structure. This study evaluated in an arid shrubland the influence of disturbance by an endemic rodent on community fun...
Article
• Relative growth rate (RGR) plays an important role in plant adaptation to the light environment through the growth potential/survival trade‐off. RGR is a complex trait with physiological and biomass allocation components. It has been argued that herbivory may influence the evolution of plant strategies to cope with the light environment, but litt...

The climbing habit is a key innovation in plants: climbing taxa have higher species richness than non-climbing sister groups. We evaluated the hypothesis that climbing plant species show greater among-population genetic differentiation than non-climber species. We compared the among-population genetic distance in woody climbers (8 species, 30 popul...
Article

In herbivorous insects, differences in the degree of specialization to host plants emerge when the distribution of an herbivore differs from that of its host plants, which results in a mosaic of populations differing in performance on the different host plants. Using a specialized butterfly, Battus polydamas archidamas Boisduval, 1936, which feeds...
Article
Full-text available
One of the central questions in evolutionary ecology is how different functional capacities impact fitness, and how it varies across populations. For instance, do phenotypic attributes influence fitness similarly across geographic gradients? Which traits (physiological, morphological and life history) are most likely to be targets of natural select...

The effects of disturbance on diversity depend on the environmental conditions. Here, we assessed the role of natural disturbance by an endemic fossorial rodent (Spalacopus cyanus) on plant invasions and its consequence on ecological and phylogenetic community structure in an arid ecosystem. Exotic taxa tend to be associated with disturbed sites, a...

The knowledge derived from Antarctic ecology may be fundamental to facing the complex environmental future of the world. As an early warning system, a deep understanding of Antarctic ecosystems is therefore needed, but Antarctic ecology as a field is still very young and currently under consolidation. Around the world, 55 nations are involved in th...

Full-text available
The climbing habit is an evolutionary key innovation in plants because it is associated with enhanced clade diversification. We tested whether patterns of species divergence and variation of three ecophysiological traits that are fundamental for plant adaptation to light environments (maximum photosynthetic rate [Amax], dark respiration rate [Rd],...
Article
Full-text available
Is physiological performance a suitable proxy of fitness in plants? Although, several studies have been conducted to measure some fitness-related traits and physiological performance, direct assessments are seldom found in the literature. Here, we assessed the physiology-fitness relationship using second-generation individuals of the invasive plant...

Antarctica is a highly interesting region for ecologists because of its extreme climatic conditions and the uniqueness of its species. In this article, we describe the trends in Antarctic ecological research participation by Latin American countries. In a survey of articles indexed by the ISI Web of Science, we searched under the categories ''Ecolo...

The climbing habit is a key innovation in angiosperm evolution: climbing plant taxa have greater species richness than their non-climbing sister groups. It is considered that highly diversified Glades should show increased among-population genetic differentiation. Less clear is the expected pattern regarding within-population genetic diversity in s...

Article
There is limited evidence regarding the adaptive value of plant functional traits in contrasting light environments. It has been suggested that changes in these traits in response to light availability can increase herbivore susceptibility. We tested the adaptive value of plant functional traits linked with carbon gain in contrasting light environm...
Article
1. The ability to display functional responses to shading, i.e. phenotypic changes that enhance plant performance in low light, is fundamental for plant success in forest communities. Herbivory may constrain plant functional responses to shading and this could explain the often observed lower plant tolerance of herbivore damage in the shade. 2. We...

Differential herbivory and/or differential plant resistance or tolerance in sun and shade environments may influence plant distribution along the light gradient. Embothrium coccineum is one of the few light-demanding tree species in the temperate rainforest of southern South America, and seedlings are frequently attacked by insects and snails. Herb...
