Quantifying past forest cover and biomass changes in the Ecuadorian Amazon. [PDF]

New Phytol
Summary Here, we developed and applied models to quantitatively reconstruct forest cover and biomass changes at three lakes in northwestern Amazonia over the past > 1500 yr. We used remotely sensed data and a modern dataset of 50 Amazonian lakes to develop generalized linear models that predict aboveground biomass, using phytolith morphotypes and ...

Protected land enhances the survival of native aquatic macrophytes and limits invasive species spread in the Panama Canal

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 33, Issue 7, Page 737-750, July 2023., 2023
Abstract This study examined whether protected land in a tropical reservoir's catchment can promote the survival of native aquatic plants (macrophytes) and limit the spread of invasive alien plant species (macrophyte IAS), which can threaten native wildlife and require expensive remediation.

Effects of salinity and temperature on tuber sprouting and growth of Schoenoplectus nipponicus

Ecosphere, Volume 12, Issue 3, March 2021., 2021
Abstract In a scenario of climate change and intensive land‐use change, the issue of salt marsh degradation caused by global warming and soil salinization is becoming more serious. A climate chamber experiment was conducted to examine the responses of tuber sprouting and seedling growth of Schoenoplectus nipponicus to variations in the temperature ...

Fire threatens the diversity and structure of tropical gallery forests

Ecosphere, Volume 12, Issue 1, January 2021., 2021
Abstract Gallery forests are widespread in most tropical savanna landscapes creating a mosaic of grass‐dominated systems with tree components and forest patches. Interactions among water, nutrient availability, and wildfires have influenced the structure, patterns, and processes of these landscape systems and have shaped today’s biodiversity in the ...

Análisis del estado poblacional de los arracachales Montrichardia arborescens (L) Schott (Araceae) en la llanura aluvial de la cuenca del Atrato, Chocó, Colombia

Revista Bioetnia, 2016
Se estudió una población de Montrichardia arborescens en tres localidades (Carmen de Darién, Riosucio y Unguía), correspondientes a un bosque inundable de la llanura aluvial del río Atrato. En cada localidad se delimitaron cinco parcelas temporales de 20x50 m cada una, bajo un muestreo aleatorio simple al azar.

Floral biology and visitors of Montrichardia arborescens (L.) Schott (Araceae) in Caxiuanã National Forest, Amazon Region, Brazil

Boletim do Museu Paraense Emílio Goeldi - Ciências Naturais, 2014
The genus Montrichardia is widely distributed across the Brazilian Amazon, however very little is known about its floral biology and floral visitors. This study, carried out over four days in September 2011 in the Caxiuanã National Forest aimed to investigate aspects of floral biology such as inflorescence growth, reproductive function, fruit size and ...
