Phenology patterns across a rupestrian grassland altitudinal gradient
(2016-01-01)
Phenology is the study of recurrent biological events in the life cycle of organisms. For plants, reproductive events such as flowering and fruiting are critical stages in their life cycles, which also greatly affect other ...
Restoring grasslands with arbuscular mycorrhizal fungi around remnant patches
(Wiley Blackwell Publishing, Inc, 2016-01)
Ecological restoration of species-rich grasslands remains a priority for conservation of biodiversity. Torrez et al. (Applied Vegetation Science, this issue) determined if plant species recolonization of degraded nutrient-poor ...
Composition, diversity, and value of ecological importance in Andean grassland ecosystems according to the altitudinal gradient in the Huacracocha micro-watershed, Peru
(Sciencedomain InternationalIN, 2023-08-12)
Aims: determine the composition and floristic diversity, the similarity between sites based on the distribution of species in the altitudinal gradient, and determine the value of ecological importance, in Andean grassland ...
Plant phylogenetic diversity of tropical mountaintop rocky grasslands: local and regional constraints
(2019-12-01)
Mountains are interesting systems for studying patterns of diversity distribution and the role of environmental filters and competition on community assembly. According to the phylogenetic niche conservatism theory, the ...
Edaphic patchiness influences grassland regeneration from the soil seed bank in mountain grasslands of central Argentina
(Wiley Blackwell Publishing, Inc, 2001-04)
The soil seed- banks in the main natural vegetation patches that makes up mountain grasslands on granite substrates in central Argentina were studied. The main natural vegetation types are moist swards, tall- tussock ...
Vegetation change in response to grazing exclusion in montane grasslands, Argentina
(National Botanic National Botanic Garden of Belgium and Royal Botanical Society of Belgium, 2012-11)
Background and aims – Natural montane grasslands in the Southern Pampas of Argentina are expected to show a high potential for recovery after heavy grazing due to their evolutionary history in the presence of large herbivores ...
Resilience and restoration of tropical and subtropical grasslands, savannas, and grassy woodlands
(2019-04-01)
Despite growing recognition of the conservation values of grassy biomes, our understanding of how to maintain and restore biodiverse tropical grasslands (including savannas and open-canopy grassy woodlands) remains limited. ...
Effects of grassland burning on reproductive success of globally threatened Strange-tailed Tyrants Alectrurus risora
(Cambridge University Press, 2011-12)
The north-east of Argentina contains a high number of globally threatened grassland birds and is increasingly managed for livestock, with annual burning in remaining natural grasslands. The Strange-tailed Tyrant Alectrurus ...
Restoring Brazilian savanna ground layer vegetation by topsoil and hay transfer
(Wiley-Blackwell, 2018-01-01)
Tropical grassy biomes have been widely neglected for conservation and, after unplanned land use conversion, ecological restoration becomes urgent. The majority of interventions have been based on the misapplication of ...
Fire as stimulant of shrub recruitment in northwestern Patagonian (Argentina) grasslands
(Springer Tokyo, 2013-06)
One strategy of plant survival during post-fire succession is to persist and regenerate by recruiting new individuals from a fire-resistant seed bank. The heat, smoke, and charcoal released during plant combustion may act ...
