Cryptic diversity in southern African kelp
Madeira, Pedro; Reddy, Maggie M.; Assis, Jorge; Bolton, John J.; Rothman, Mark D.; Anderson, Robert J.; Kandjengo, Lineekela; Kreiner, AnjaThe southern coast of Africa is one of the few places in the world where water temperatures are predicted to cool in the future. This endemism-rich coastline is home to two sister species of kelps of the genus Ecklonia maxima and Ecklonia radiata, each associated with specific thermal niches, and occuring primarily on opposite sides of the southern tip of Africa. Historical distribution records indicate that E....
Range-edge populations of seaweeds show niche unfilling and poor adaptation to ...
Hernández, Sandra; García, Ana G.; Arenas, Francisco; Escribano, M. Pilar; Jueterbock, Alexander; De Clerck, Olivier; Maggs, Christine; Franco, Joao N.Aim: Global warming is affecting the distribution of species worldwide, but the level of adaptation of edge populations to warmer temperatures remains an open question. Here, we assess the thermal tolerance of populations of two habitat-forming seaweeds along their latitudinal range, using thermal niche unfilling to assess their resilience to global warming. Location: European Atlantic coastline. Taxon: Ascophy...
Marine biodiversity exposed to prolonged and intense subsurface heatwaves
Fragkopoulou, Eliza; Sen Gupta, Alex; Costello, Mark John; Wernberg, Thomas; Araújo, Miguel B.; Serrao, Ester; De Clerck, Olivier; Assis, JorgeMarine heatwaves (MHWs) are becoming increasingly common, with devastating ecosystem impacts. However, MHW understanding has almost exclusively relied on sea surface temperature with limited knowledge about their subsurface characteristics. Here we estimate global MHWs from the surface to 2,000 m depth, covering the period 1993-2019, and explore biodiversity exposure to their effects. We find that MHWs are typi...
Non-indigenous seaweeds in the Northeast Atlantic Ocean, the Mediterranean Sea ...
van der Loos, Luna M.; Bafort, Quinten; Bosch, Samuel; Ballesteros, Enric; Bárbara, Ignacio; Berecibar, Estibaliz; Blanfuné, Aurélie; Bogaert, KennyEffective monitoring of non-indigenous seaweeds and combatting their effects relies on a solid confirmation of the non-indigenous status of the respective species. We critically analysed the status of presumed non-indigenous seaweed species reported from the Mediterranean Sea, the Northeast Atlantic Ocean and Macaronesia, resulting in a list of 140 species whose non-indigenous nature is undisputed. For an addit...
Salinity and host drive Ulva‐associated bacterial communities across the Atlant...
Van der Loos, Luna M.; D’hondt, Sofie; Engelen, Aschwin; Pavia, Henrik; Toth, Gunilla B.; Willems, Anne; Weinberger, Florian; De Clerck, OlivierThe green seaweed Ulva is a model system to study seaweed-bacteria interactions, but the impact of environmental drivers on the dynamics of these interactions is little understood. In this study, we investigated the stability and variability of the seaweed-associated bacteria across the Atlantic-Baltic Sea salinity gradient. We characterized the bacterial communities of 15 Ulva sensu lato species along 2,000 km...
Global biodiversity patterns of marine forests of brown macroalgae
Fragkopoulou, Eliza; Serrao, Ester; De Clerck, Olivier; Costello, Mark J.; Araújo, Miguel B.; Duarte, Carlos M.; Krause‐Jensen, Dorte; Assis, JorgeAim Marine forests of brown macroalgae create essential habitats for coastal species and support invaluable ecological services. Here, we provide the first global analysis of species richness and endemicity of both the kelp and fucoid biomes. Location Global. Time period Contemporary. Major taxa studied Marine forests of brown macroalgae, formed by kelp (here defined as orders Laminariales, Tilopteridales and D...
Lobophora (Dictyotales, Phaeophyceae) from the western Indian Ocean: diversity ...
Vieira, Christophe; Rasoamanendrika, Faravavy A.; Zubia, Mayalen; Bolton, John J.; Anderson, Robert J.; Engelen, Aschwin; D'hondt, SofieThe brown algal genus Lobophora (Dictyotales, Phaeophyceae) is an important ecological component of tropical marine systems. Although still scantily sampled, 35 species of Lobophora were discovered previously from the western Indian Ocean. This study updates previous diversity estimates by incorporating recent collections from Madagascar, Mozambique, and the Red Sea, considerably improving our knowledge of Lobo...
Concise review of the genus Caulerpa J.V. Lamouroux
Zubia, Mayalen; Draisma, Stefano G. A.; Morrissey, Kathryn Lee; Varela-Álvarez, Elena; De Clerck, OlivierThe genus Caulerpa is highly diverse, especially in the Caribbean Sea, the Indo-Malay archipelago and the temperate waters of southern Australia. Currently, more than 100 species are recognized worldwide. Despite recent advances in taxonomy and phylogeny, there is still confusion about the delimitation and identification of some species due to tremendous phenotypic plasticity. Caulerpa is known to occupy a wide...
Complete mitochondrial genomes of six species of the freshwater red algal order...
Paiano, Monica O. [UNESP]; Del Cortona, Andrea; Costa, Joana F.; Liu, Shao-Lun; Verbruggen, Heroen; De Clerck, Olivier; Necchi Jr, Orlando [UNESP]Made available in DSpace on 2019-10-04T12:30:39Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-01-01; Only two mitochondrial (mt) genomes had been reported in members of the red algal order Batrachospermales, which are confined to freshwater habitats. Additional mt genomes of six representative members (Batrachospermum macrosporum, Kumanoa ambigua, K. mahlacensis, Paralemanea sp., Sheathia arcuata, and ...
Diversity and origin of the genus Lobophora in the Mediterranean Sea including ...
Vieira, Christophe; Aharonov, Andre; Paz, Guy; Engelen, Aschwin; Tsiamis, Konstantinos; Einav, Rachel; De Clerck, OlivierThe brown algal genus Lobophora is widely reported from the Mediterranean Sea. Contrary to studies in the Indo-Pacific and Caribbean regions, little attention has been given to Lobophora in the Mediterranean Sea, at least using molecular tools. To address this knowledge gap, we sampled specimens across the Mediterranean Sea (Spanish coast, Balearic Islands, Greece and Israel), with an exhaustive effort in the B...
