Aquatic macrophyte growth season in Central and Northern European Union and the implications for aquatic macrophyte risk assessments for herbicides

Integrated Environmental Assessment and Management, Volume 20, Issue 4, Page 1125-1139, July 2024.
Abstract Under current European Union regulation, the risks to aquatic organisms must be assessed for uses of plant protection products (PPPs) that may result in exposure to the environment. For herbicidal PPPs, aquatic macrophytes are often the most sensitive taxa.

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

Frontiers 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.

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

Journal 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.

Eficiência da adubação orgânica com esterco bovino e com Egeria densa Efficiency of organic fertilization with cattle manure and Egeria densa

Revista Brasileira de Ciência do Solo, 2007
Informações sobre a eficiência de uso dos nutrientes aplicados na adubação orgânica são ainda escassas. As recuperações aparentes dos nutrientes aplicados como esterco bovino e como restos de Egeria densa foram comparadas.

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

New 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 ...
