Distributed in tropical and warm‐temperate waters worldwide, Lobophora species are found across the Greater Caribbean (i.e., Caribbean sensu stricto, Gulf of Mexico, Florida, the Bahamas, and Bermuda). We presently discuss the diversity, ecology, biogeography, and evolution of the Greater Caribbean Lobophora species based on previous studies and an extensive number of samples collected across the eastern, southern, and to a lesser extent western Caribbean. A total of 18 Lobophora species are now documented from the Greater Caribbean, of which five are newly described (L. agardhii sp. nov., L. dickiei sp. nov., L. lamourouxii sp. nov., L. richardii sp. nov., and L. setchellii sp. nov.). Within the Greater Caribbean, the eastern Caribbean and the Central Province are the most diverse ecoregion and province (16 spp.), respectively. Observed distribution patterns indicate that Lobophora species from the Greater Caribbean have climate affinities (i.e., warm‐temperate vs. tropical affinities). In total, 11 Lobophora species exclusively occur in the Greater Caribbean; six are present in the western Atlantic; two in the Indo‐Pacific; and one in the eastern Pacific. Biogeographic analyses support that no speciation occurred across the Isthmus of Panama, and that the Greater Caribbean acted as a recipient region for species from the Indo‐Pacific and as a region of diversification as well as a donor region to the North‐eastern Atlantic. The Greater Caribbean is not an evolutionary dead end for Lobophora, but instead generates and exports diversity. Present results illustrate how sampling based on DNA identification is reshaping biogeographic patterns, as we know them.

Is Delicata Krammer a validly published genus name? Trying to put light on Article 20.2

SummaryThis paper delves into the intricacies of botanical nomenclature, specifically focusing on the interpretation and application of Art. 20.2 of the International Code of Nomenclature (ICN). It critically analyzes the case of Delicata Krammer, against the backdrop of Art. 20.2. The investigation shows that Delicata does not coincide with any established Latin technical term used in morphology and hence fulfills the ICN requirements, confirming its validity. This finding highlights the need for clearer guidelines in distinguishing descriptive Latin terms from technical terms used in morphology. This paper contributes to the ongoing discourse in botanical taxonomy by advocating for revised practices and interpretations of nomenclatural rules, ensuring stability and precision in the naming of taxa.

Cryptic diversity in the macroalgal genus Lobophora (Dictyotales) reveals environmental drivers of algal assemblages

et al. 2020

Stress-induced reductions in the world's coral populations are, in many locations, giving way to an increase in macroalgae, for example the common brown macroalgal genus Lobophora. While many ecological studies report a single species (Lobophora variegata), DNA-based identification methods have recently shown that Lobophora is a highly diverse genus with over 100 reported species. Here, we aim to identify possible ecological differences among Lobophora species by investigating environmental drivers of Lobophora assemblages. We sampled Lobophora thalli from 12 reefs around Palau (Micronesia) at varying depths, wave exposure, and herbivore biomass. Using one mitochondrial marker (cox3) and two chloroplast markers (psbA, rbcL), we uncovered a striking cryptic diversity of 15 species, including 8 undescribed taxa. Associations between potential drivers and Lobophora assemblages varied at two spatial scales. At the larger scale of both island coastlines only a single variable-wave exposure-was found to be important. On a smaller geographic scale, confined to the east coast, all factors-wave exposure, depth and herbivory-were associated with assemblages of Lobophora. Widespread sampling indicates the presence of generalist species, which were found in most sampled habitats, and specialists, which occupy specific habitats. Such high levels of cryptic diversity have important implications for ecological studies. Given that species inhabit different environments, have a variable growth form, and have a threefold difference in thallus thickness, it seems likely that species differ in their function. If these differences manifest in competitive strengths, these results have broad implications for our understanding of coral reef recovery following perturbation.
