Plant traits related to leaf decomposition processes in arid ecosystems of northern Patagonia
(Oxford University Press, 2019-04)
Aims: Plants play an important role in ecosystem processes. Functional meaning of trait variation in wide environmental gradients is well known but is scarcely known across narrow gradients. We analyze the variation of ...
Functional traits reveal environmental constraints on amphibian community assembly in a subtropical dry forest
(Wiley Blackwell Publishing, Inc, 2018-09)
The relationships between functional traits and environmental gradients are useful to identify different community assembly processes. In this work, we used an approach based on functional traits to analyse if changes in ...
Seed predation does not explain pine invasion success
(Springer, 2019-03)
Why some non-native plant species invade, and others fail remains an elusive question. Plant invasion success has been associated with specific species traits. Yet, we have limited knowledge of the mechanisms relating these ...
Contrasting levels of genotype by environment interaction for life history and morphological traits in invasive populations of Zaprionus indianus (Diptera: Drosophilidae)
(Wiley Blackwell Publishing, Inc, 2019-07)
It has been demonstrated that phenotypic plasticity and genotype by environment interaction are important for coping with new and heterogeneous environments during invasions. Zaprionus indianus Gupta (Diptera: Drosophilidae) ...
Developing a breeding strategy for multiple trait selection in Prosopis alba Griseb., a native forest species of the Chaco Region in Argentina
(Oxford University Press, 2017-03)
Prosopis alba is a native forest tree growing in arid and semi-arid regions of Argentina. It is a multipurpose species suitable for silvopastoral systems. The breeding programmes of P. alba in Argentina started ~25 years ...
Filtering processes in the assembly of plant communities: Are species presence and abundance driven by the same traits?
(Wiley Blackwell Publishing, Inc, 2007-12)
Question: Is the response of plant traits to environment at the community level similar when considering species abundance and when considering species presence only? Location: Mountain grasslands, central Argentina. ...
Study of the polymorphism of the Patagonian Calceolaria polyrhiza(Calceolariaceae) using decision tree and sequential covering rule induction
(Wiley Blackwell Publishing, Inc, 2013-09)
Climate and landscape changes that occurred in Patagonia during the Pleistocene presumably led to the ample biodiversity that currently characterizes the region. Many Patagonian species constitute unresolved complexes that ...
Study of the polymorphism of the Patagonian Calceolaria polyrhiza (Calceolariaceae) using decision tree and sequential covering rule induction
(Wiley Blackwell Publishing, Inc, 2013-11)
Climate and landscape changes that occurred in Patagonia during the Pleistocene presumably led to the ample biodiversity that currently characterizes the region. Many Patagonian species constitute unresolved complexes that ...
Disentangling morphologically similar species of the Andean forest: Integrating results from multivariate morphometric analyses, niche modelling and climatic space comparison in Kaunia (Eupatorieae: Asteraceae)
(Wiley Blackwell Publishing, Inc, 2018-01)
Six subtropical montane forest Kaunia spp. are remarkable for their superficial morphological similarity. We aim to explore different sources of data to clarify species delimitation in this complex of Kaunia. Morphological ...
Dominant native and non-native graminoids differ in key leaf traits irrespective of nutrient availability
(Wiley Blackwell Publishing, Inc, 2020-07)
Aim: Nutrient enrichment is associated with plant invasions and biodiversity loss. Functional trait advantages may predict the ascendancy of invasive plants following nutrient enrichment but this is rarely tested. Here, ...
