Abstract
The red alga Tiffaniella gorgonea (Wrangeliaceae, Rhodophyta) is found and described for the first time from the Mediterranean Sea. This species was collected growing as epiphyte on three species of Codium in the lower intertidal zone from Dalya, Cabo Negro and Al-Hoceima on the Mediterranean coast of Morocco. Moroccan specimens were studied in detail and compared with two other closely related species reported previously from Morocco and the Mediterranean Sea. A key to the Mediterranean and Moroccan species of Tiffaniella is provided. Habitat, geographical distribution, and the possible vector of introduction of the new alien are presented and discussed in this work. Taxonomic remarks, a description and images of the macroscopic and microscopic characters are provided for this taxon.
About the authors
Ghizlane Salhi is a PhD student of Marine Biology at the Department of Biology. She obtained her MSc in Engineering in Ecology and Biodiversity Management from Abdelmalek Essâadi University. Her research focus is on ecology, taxonomy, anticancer activity and chemical compounds of macroalgae. Her main research interests are also applied to the biodiversity and valorization of macroalgae in the Strait of Gibraltar.
Mustapha Hassoun is a PhD candidate in Ecology and Marine Biology at Department of Biology. He is a marine biologist specializing in the systematics of macroalgae. His research interests focus on the study of algal populations of the Moroccan Atlantic coast.
Hanaa Moussa is a PhD student at universities Abdelmalek Essâadi and Santiago de Compostela. Currently, her research focuses on the biodiversity of seaweeds from Al-Hoceima National Park (Mediterranean Sea) and their chemical properties and pharmacological activities.
Hanaa Zbakh is a biologist at the University of Abdelmalek Essâadi (Morocco) since 2006. She obtained her PhD in Marine Biology in 2014, her research focuses on macroalgal biodiversity and on finding bioactive compounds from seaweeds as potent anticancerogenic and anti-inflammatory agents both in vitro and in vivo.
Mohamed Kazzaz is currently Professor in the Department of Biology, Faculty of Sciences, University of Abdelmalk Essaadi. He obtained his PhD in Biology in 2003 (specializing in marine algae) from the Faculty of Sciences of Tetouan. His research covers taxonomy of marine benthic algae.
Hassane Riadi is currently Professor of Plant Ecology and Botany in the Department of Biology and Vice Dean for Scientific-Research Affairs and Cooperation at the Faculty of Sciences, University of Abdelmalek Essâadi. He obtained his PhD in Biology in 2000 (specializing in marine algae) from the Faculty of Sciences of Tetouan. Dr. Riadi’s research covers taxonomy of marine benthic algae, the impact of various factors of anthropogenic or natural origins on marine plant communities, and applied aspects of marine seaweed. He is a co-author of many publications related to algal research, and since 1998 has co-authored several taxonomic publications on some Moroccan taxa.
