Floral allocation at different altitudes in highly autogamous alpine Chaetanthera euphrasioides (Asteraceae) in the central Chilean Andes
(Swiss Botanical Society, 2012-11-20)
In the alpine life-zone, increasingly slower and
unpredictable pollination at the higher altitudes predict an
increase in floral investment in strongly outcrossing, pollenlimited
biotically pollinated plant species, but ...
Temperature-driven flower longevity in a high-alpine species of Oxalis influences reproductive assurance
(2013)
How high-alpine plants confront stochastic conditions for animal pollination is a critical question. We investigated the effect of temperature on potential flower longevity (FL) measured in pollinator-excluded flowers and ...
Plant–plant interactions promote alpine diversification
(Springer, 2019-04)
Plant–plant interactions can promote diversification in harsh environments through (1) natural selection producing divergent adaptations to extreme and varying abiotic conditions in plants that grow in the open, or (2) ...
Climate change and alpine stream biology: progress, challenges, and opportunities for the future
(BLACKWELL PUBLISHING LTD, 2017-11-01)
In alpine regions worldwide, climate change is dramatically altering ecosystems and affecting biodiversity in many ways. For streams, receding alpine glaciers and snowfields, paired with altered precipitation regimes, are ...
Relative growth of carcass tissues of goat kids from five breed types finished on pasture or feedlot
(2016-03-01)
The aim of this study was to evaluate the effect of cross breeding, finishing system, and gender on the relative growth of carcass tissues of dairy kids. Seventy eight kids (39 male and 39 female) from five breed types ...
Impacts of experimental trampling by hikers and pack animals on a high-altitude alpine sedge meadow in the Andes
(Taylor & Francis Ltd, 2015-03)
Background: Damage to alpine plant communities is likely to occur when hikers and pack animals trample vegetation. Currently, there is limited research that quantifies and compares impacts from these activities. Aims: A ...
Short-term effects of pack animals grazing exclusion from Andean Alpine Meadows
(Inst Arctic Alpine Res, 2014-05)
Grazing by livestock can have positive, neutral, and/or negative effects on vegetation depending on the intensity and type of grazing. This includes grazing by pack animals used for tourism in mountain protected areas. We ...
