Regional Genetic Structure in the Aquatic Macrophyte Ruppia cirrhosa Suggests Dispersal by Waterbirds [PDF]

open access: yes, 2017
The evolutionary history of the genus Ruppia has been shaped by hybridization, polyploidisation and vicariance that have resulted in a problematic taxonomy. Recent studies provided insight into species circumscription, organelle takeover by hybridization,

Observaciones sobre un coportamiento atípico de Ruppia maritima L. en una laguna costera tropical

open access: yesBotan‪ical Sciences, 1977
Ruppia marítima está presente en la Laguna de Sontecomapan durante todo el año. Su distribución en la laguna parece depender de la acción conjunta de varios factores. Entre ellos, turbidez, corrientes y pH actúan como limitantes.

Spatial genetic structure reveals migration directionality in Mediterranean Ruppia spiralis (Western Sicily)

open access: yesFrontiers in Marine Science, 2022
Mediterranean salinas, originally built for salt production, function as alternative wetlands. A variety of accompanying lagoon, ditch, and marsh systems are suitable habitats for salt-tolerant submerged macrophytes and often characterized by ...

The light requirements for growth and photosynthesis in seagrasses with emphasis on Texas estuaries : a literature survey [PDF]

open access: yes, 1993
During the last 20 years, seagrass communities throughout the world have experienced decreased productivity and distribution. These declines have often been attributed to decreased water transparency as a result of turbidity or shading by epiphytic algae.

Diversity and Variation of Epiphytic Diatoms on Ruppia maritima L., Related to Anthropogenic Impact in an Estuary in Southern Brazil

open access: yesDiversity, 2022
Knowledge about the diversity and spatiotemporal variability of epiphytic diatom communities in estuarine meadows has great relevance for coastal ecology and, thus, contributes to understanding the impact of natural and anthropogenic changes on seagrass ...

Seagrass radiation after Messinian salinity crisis reflected by strong genetic structuring and out-of-Africa scenario (Ruppiaceae). [PDF]

open access: yesPLoS ONE, 2014
Many aquatic plant and seagrass species are widespread and the origin of their continent-wide ranges might result from high gene flow levels. The response of species when extending northwards since the Last Glacial Maximum can be opposed to the ...

Texas coastal zone biotopes : an ecography : interim report for the Bay and Estuary Management Program (CRMP) [PDF]

open access: yes, 1972
November 1972Because esthetics, biological environment and physiography are so interrelated and have changeable meanings in various environments, we are obligated to think of the environment in terms of biological change, as environmental protection is ...
