Variación temporal de la biomasa del perifiton de Egeria densa Planch. en un arroyo pampeano [PDF]

open access: yes, 2010
Se analiza la variación de descriptores de la biomasa del perifiton (peso seco, peso orgánico, y clorofila-a) sobre Egeria densa durante 21 meses de muestreo en el arroyo Las Flores, un arroyo pampeano afluente del Río Luján.

Sensitivity of amphibian embryos to timing and magnitude of present and future thermal extremes

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 341, Issue 4, Page 377-388, May 1, 2024.
Abstract Ongoing climate change is increasing the frequency and intensity of extreme temperature events. Unlike the gradual increase on average environmental temperatures, these short‐term and unpredictable temperature extremes impact population dynamics of ectotherms through their effect on individual survival.

Integration of cell differentiation and initiation of monoterpenoid indole alkaloid metabolism in seed germination of Catharanthus roseus

open access: yesNew Phytologist, Volume 242, Issue 3, Page 1156-1171, May 2024.
Summary In Catharanthus roseus, monoterpenoid indole alkaloids (MIAs) are produced through the cooperation of four cell types, with final products accumulating in specialized cells known as idioblasts and laticifers. To explore the relationship between cellular differentiation and cell type‐specific MIA metabolism, we analyzed the expression of MIA ...

Long-Term Habitat Degradation Drives Neotropical Macrophyte Species Loss While Assisting the Spread of Invasive Plant Species

open access: yesFrontiers in Ecology and Evolution, 2019
The spread of invasive macrophyte species is a pressing threat to neotropical shallow lakes. Yet there are few studies addressing the full extent of biotic and abiotic changes that may occur in response to invasive species.

The Rise and Fall of Water Net (Hydrodictyon reticulatum) in New Zealand [PDF]

open access: yes, 1999
During the late 1980s to early 1990s a range of aquatic habitats in the central North Island of New Zealand were invaded by the filamentous green alga, water net Hydrodictyon reticulatum (Linn. Lagerheim).

What is the effectiveness of methods for eradicating or controlling abundance and biomass of invasive aquatic plants in Canada? A systematic review protocol

open access: yesEcological Solutions and Evidence, Volume 5, Issue 2, April/June 2024.
This protocol sets out the research methodologies for a systematic review examining the effectiveness of control methods (e.g., biological, chemical and physical) for eradicating or controlling invasive aquatic plant species impacting or likely to impact Canadian freshwater systems.

Photosynthetic rate of the aquatic macrophyte Egeria densa Planch. (Hydrocharitaceae) in two rivers from the Itanhaém River Basin in São Paulo State, Brazil

open access: yesBrazilian Archives of Biology and Technology, 2004
Egeria densa is a submerged aquatic macrophyte which, in Brazil, causes problems specially for electric energy generation. The purpose of this study was to evaluate the photosynthetic rate of E.

Large‐scale validation of 46 invasive species assays using an enhanced in silico framework

open access: yesEnvironmental DNA, Volume 6, Issue 2, March–April 2024.
It can be challenging to ensure that eDNA assays are specific to their intended targets, particularly when biodiversity is high and the geographic area is large. Here, we use an accurate machine‐learning‐based PCR model to streamline validation of 46 qPCR assays targeting invasive species throughout the continental United States. We present an overview
