Species are hypotheses: avoid connectivity assessments based on pillars of sand
TLDR
This study illustrates how the failure to recognize boundaries of evolutionary‐relevant unit leads to heavily biased estimates of connectivity, and reviews the conceptual framework within which species delimitation can be formalized as falsifiable hypotheses and how connectivity studies can feed integrative taxonomic work and vice versa. Expand
Phylogenetic analyses of Caulerpa taxifolia (Chlorophyta) and of its associated bacterial microflora provide clues to the origin of the Mediterranean introduction
TLDR
Two independent lines of evidence are presented that support an Australian origin for the Mediterranean populations of C. taxifolia, which are mainly associated with Mediterranean and Australian samples. Expand
Decline in Kelp in West Europe and Climate
TLDR
It is shown that many populations of L. digitata along European coasts are on the verge of local extinction due to a climate-caused increase in sea temperature, and the possible implications of global climate change for the geographical patterns of the species using temperature data from theCMIP5 are evaluated. Expand
A review of the life history, reproduction and phenology of Gracilaria
TLDR
The basic life history of the red alga Gracilaria is of the three-phase Polysiphonia type but a number of species show deviations, potentially important in planning and executing GracilarIA cultivation. Expand
What controls haploid—diploid ratio in the red alga, Gracilaria verrucosa?
The conditions for maintenance of a haploid—diploid life cycle in the species Gracilaria verrucosa were studied. This species is a red alga, where haploid plants have separate sexes. In the twoExpand
Genetic Variation in Wild and Cultivated Populations of the Haploid– Diploid Red Alga Gracilaria chilensis: How Farming Practices Favor Asexual Reproduction and Heterozygosity
TLDR
This study suggested that cultural practices in the southern part of the country contributed to the spread of selected genotypes at a local scale and document for the first time that involuntary selection could operate during the first step of domestication in a marine plant. Expand
Mating system and gene flow in the red seaweed Gracilaria gracilis: effect of haploid–diploid life history and intertidal rocky shore landscape on fine-scale genetic structure
TLDR
It is established that effective migration rates varied according to height on the shore in this intertidal species, and biased spore dispersal may occur during the transport of spores and gametes at low tide when small streams flow from high- to lower-shore pools. Expand
Performance of non–motile male gametes in the sea: analysis of paternity and fertilization success in a natural population of a red seaweed, Gracilaria gracilis
TLDR
Not only is fertilization efficient, but that male–male competition and/or female choice may play a role in shaping population mating patterns, as well as showing that cystocarp yield is not sperm limited and that the large variation in male fertilization success cannot be solely explained by the distance travelled by the male gamete to find a mate. Expand
Using genetic tools for sustainable management of kelps: a literature review and the example of Lami
TLDR
The analyses of spatio-temporal variation clearly demonstrate the effect of small population sizes on the genetic instability of isolated L. digitata populations and have implications for managing this genetic resource. Expand
Complex life cycles of multicellular eukaryotes: new approaches based on the use of model organisms.
TLDR
An emerging model organism from the brown algae is described, Ectocarpus siliculosus, and the potential of this system for the investigation of the mechanisms that regulate complex life cycles is highlighted. Expand
