Effects of forest preservation, livestock exclusion and use of shrubs as potential nurses on planting success of an endangered tree
(Wiley Blackwell Publishing, Inc, 2021-05-27)
Domestic livestock are widespread in seasonally dry forests, likely causing forest degradation and limiting tree seedling establishment. Shrubs can play an important role in facilitating tree regeneration, by protecting ...
Direct vs. indirect facilitation (herbivore-mediated) among woody plants in a semiarid Chaco forest: a spatial association approach
(Wiley, 2015-01)
In arid environments, direct facilitation (microhabitat amelioration) and indirect facilitation (‘associational resistance’ via protection from herbivory) among plants of different species may act simultaneously. Little ...
Association between native tree sapling and spiny shrub mitigates browsing damage produced by large herbivores in fire-degraded forests
(Elsevier Gmbh, 2021-12)
Spiny shrubs can generate positive interactions with palatable trees in sites affected by abiotic and biotic stress (e.g. fire, and consumption by herbivores). The objective of this study was to assess the role of native ...
Structural anti-herbivore defense reduction of two Patagonian spiny shrubs in response to long time exclusion of large herbivores
(Academic Press Ltd - Elsevier Science Ltd, 2017-07)
This work focuses on the structural defenses of the two dominant spiny shrub species of the Patagonian shrub-grass steppe. We compared the amount of structural defenses (spines and thorns) of Mulinum spinosum (Cav.) Pers. ...

Changes in traits of shrub canopies across an aridity gradient in northern Patagonia, Argentina
(Elsevier Gmbh, Urban & Fischer Verlag, 2010-12)
Low and highly variable precipitation pulses exert a strong selective pressure on plant traits and this might provide axes of ecological differentiation among plant species in arid ecosystems. We asked whether aridity ...
Phylogenetic reconstruction of the genus Tephrocactus (Cactaceae) based on molecular, morphological, and cytogenetical data
(International Association for Plant Taxonomy, 2019-08)
Tephrocactus comprises species mainly endemic to Argentina. Molecular phylogenetic analyses of all proposed species of the genus as well as classical (chromosome number, karyotype) and molecular cytogenetical techniques ...
In the Grounds of St. Hilary's School, Trinidad, B.W.I.
(Patricia Lachmere Guppy, 2010-03-31)
In this painting of the grounds of St. Hilary's School, Port of Spain, Trinidad, the following vegetation are highlighted: pink Poui - an ornamental flowering tree; Bougainvillea - a spiny shrub with masses of colourful ...
A revision of the Solanum elaeagnifolium clade (Elaeagnifolium clade; subgenus Leptostemonum, Solanaceae)
(Pensoft Publishers, 2017-08)
The Solanum elaeagnifolium clade (Elaeagnifolium clade) contains five species of small, often rhizomatous, shrubs from deserts and dry forests in North and South America. Members of the clade were previously classified in ...
Slope aspect influences plant association patterns in the Mediterranean matorral of central Chile
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2005-07)
The most important processes shaping communities are likely to leave observable imprints on their spatial structure. The net outcome of positive and negative interactions among plants has been proposed to vary inversely ...
