Variations in chemical composition associated with tissue aging in palatable and unpalatable grasses native to central Argentina
(Elsevier, 2005-02)
Tissue aging in unpalatable grasses appears to be associated with a rapid decay in nutritional value because grazers usually start to avoid them at early stages of maturity. The objective of the present study was to determine ...
Decomposition and nutrient dynamic of leaf litter and roots from palatable and unpalatable grasses in a semi-arid grassland
(Elsevier Science, 2001-09)
A field experiment was conducted in a temperate semi-arid grassland of central Argentina to test the hypothesis that decomposition of and nutrient release from leaf litter and roots are faster in Poa ligularis and Stipa ...
Restoration of palatable grasses: A study case in degraded rangelands of central Argentina
(Academic Press Ltd-elsevier Science Ltd, 2008-10)
Restoration of palatable grasses on degraded rangelands dominated by unpalatable grasses in central Argentina is limited by low availability of seeds and safe sites for seedling establishment. The objective of our study ...
Use of unpalatable forages by ruminants: The influence of experience with the biophysical and social environment
(MDPI AG, 2018-04-14)
Unpalatable forage resources (low nutrient density, potentially toxic metabolites) are widespread and represent a challenge for ruminant nutrition, health, and welfare. Our objective was to synthesize the role of biophysical ...
Effect of competition intensity on recruitment of palatable and unpalatable grasses
(Wiley Blackwell Publishing, Inc, 2019-10-29)
In this study, we made an attempt to reveal how competition intensity from established plants impacts on palatable and unpalatable grass seedlings recruitment, in a natural mesic grassland of central Argentina. Our objective ...
Unpalatability of Hyla semilineata tadpoles (Anura) to captive and free-ranging vertebrate predators
(Universita Degli Studi Di Firenze, 1999-12-01)
This study examines the unpalatability of Hyla semilineata tadpoles, relating this possible defence mechanism to their black, presumably aposematic, colouration. Bullfrog tadpoles (Rana catesbeiana), similar in size to the ...

Are you experienced? Predator type and predator experience trade-offs in relation to tadpole mortality rates
(Wiley-Blackwell, 2011-06-01)
Cryptic behavior and unpalatability are common defensive strategies that occur in different taxonomic groups, but the effectiveness of these defensive strategies is context dependent, varying with predator type and ...
