Abstract Mangroves are ecosystems that are seriously threatened by climate change, particularly sea level rise and an increase of droughts. They are resilient to short droughts but their response to longer ones remains arguable. In this work, we studied the responses of R. mangle dominated forests on a carbonate island (El Rosario Island) to climate anomalies and their drivers at inter-annual, decadal and inter-decadal scales during the last centuries. Palynological analysis of a sediment core r...

Extreme events affect coastal vegetation in several ways. They cause massive tree defoliations and mortality that carry changes in vegetation structure and floristic composition. In order to assess these changes in dry tropical forests, coastal vegetation and mangroves in El Rosario archipelago, and their relationship with extreme events between 2002 and 2014, Quickbird and Worldview Satellite images with uneven periodicity were analyzed and the Normalized Difference Vegetation Index (NDVI) was ...

Mauritia flexuosa is a keystone species with a broad geographic distribution throughout the Amazon. Environmental changes can impact the reproductive success in a keystone species such as M. flexuosa, which results in a cascade of events that impacts many other species. The present study examined the reproductive phenology in the palm M. flexuosa between December 2010 and November 2012. A 1-ha plot was established in the central Amazon and all palms ≥14 m tall were labelled for measuring. The fo...

Abstract Mauritia flexuosa L.f. (swamp forest palm) stands are widely distributed in the poorly drained zones of flood plains and low terraces. They provide several economic and cultural resources for local human communities and play an important ecological role in Amazonia. To identify the main factors involved in the natural regeneration dynamics of M. flexuosa , we surveyed the recruitment, mortality, and survival rates of seedlings from June 2010 to November 2012 on a 1-ha plot in a flooded ...
