“…For example, most dispersal in the brooding coral Seriatopora hystrix is within 100 m of the natal site, but rare long-distance dispersal of 9 km or more is possible (223). In addition, dispersal distances within species can differ substantially between locations because of variations in ocean currents, with stronger currents driving more widespread gene flow (47,73).…”

Coral reefs are both exceptionally biodiverse and threatened by climate change and other human activities. Here, we review population genomic processes in coral reef taxa and their importance for understanding responses to global change. Many taxa on coral reefs are characterized by weak genetic drift, extensive gene flow, and strong selection from complex biotic and abiotic environments, which together present a fascinating test of microevolutionary theory. Selection, gene flow, and hybridization have played and will continue to play an important role in the adaptation or extinction of coral reef taxa in the face of rapid environmental change, but research remains exceptionally limited compared to the urgent needs. Critical areas for future investigation include understanding evolutionary potential and the mechanisms of local adaptation, developing historical baselines, and building greater research capacity in the countries where most reef diversity is concentrated. Expected final online publication date for the Annual Review of Genetics, Volume 57 is November 2023. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

“…The isolation of offshore populations compared with high coastal connectivity highlights the importance of bathymetric barriers, rather than isolation‐by‐distance, which has been observed in many other elasmobranchs. Fitz et al ( 2022 ) focused on the population genetic patterns of the anemonefish Amphiprion biaculeatus , comparing different geographic determinants of genetic structure. Here, the authors present models detailing whether spatial distance or dispersal with currents best explained genetic separation in this rare reef fish and concluded that, while oceanographic currents best explained genetic patterns at large scale (>150 km), isolation‐by‐distance was a stronger determinant at smaller geographic scales.…”

“…Herein, these processes are addressed in diverse empirical model systems ranging from diatoms to mollusks and fish (Green et al, 2022 ; Le Moan et al, 2022 ; Sefbom et al, 2022 ; Zhang et al, 2022 ), as well as in silico in two theoretical modeling studies (Eriksson et al, 2022 ; Marshall & Connallon, 2022 ). The link between genotype and phenotype is also the focus of several empirical studies here (Gefaell et al, 2022 ; Stenger et al, 2022 ; Walker et al, 2022 ), as is the seascape genomics of a wide range of taxa (Delaval, Bendall, et al, 2022 ; Delaval, Frost, et al, 2022 ; Fitz et al, 2022 ; Lapègue et al, 2022 ; Matias et al, 2022 ; Palumbi et al, 2022 ; Pampoulie et al, 2022 ), which has important implications for management of marine resources. Finally, the breadth of phylogenetic diversity and evolutionary history in the oceans is the topic of several articles focusing on the larval development of gastropods (Korshunova et al, 2022 ; Sun et al, 2022 ) and the evolution of small RNAs in cnidarians (Li & Hui, 2022 ).…”

This article summarizes the Evolutionary Applications Special Issue, “A decade of progress in Marine Evolutionary Biology.” The globally connected ocean, from its pelagic depths to its highly varied coastlines, inspired Charles Darwin to develop the theory of evolution during the voyage of the Beagle. As technology has developed, there has been a dramatic increase in our knowledge about life on our blue planet. This Special Issue, composed of 19 original papers and seven reviews, represents a small contribution to the larger picture of recent research in evolutionary biology, and how such advancements come about through the connection of researchers, their fields, and their knowledge. The first European network for marine evolutionary biology, the Linnaeus Centre for Marine Evolutionary Biology (CeMEB), was developed to study evolutionary processes in the marine environment under global change. Though hosted by the University of Gothenburg in Sweden, the network quickly grew to encompass researchers throughout Europe and beyond. Today, more than a decade after its foundation, CeMEB's focus on the evolutionary consequences of global change is more relevant than ever, and knowledge gained from marine evolution research is urgently needed in management and conservation. This Special Issue, organized and developed through the CeMEB network, contains contributions from all over the world and provides a snapshot of the current state of the field, thus forming an important basis for future research directions.

“…Therefore, cultural production takes precedence over meeting the international market demand for environmental information (Prasetio and Kusrini, 2012). In addition, this fish has a unique reproduction system due to its social hierarchical system, protandrous hermaphroditism, and monogamous system (Madhu et al, 2013;Klann et al, 2021;Fitz et al, 2022). This condition marks the difficulties of mass artificial spawning, limiting the seed stock and broodstock candidate supply in culture production.…”

Highlight Research The 17β-estradiol hormone induction reduces the percentage of R values in skin and fin color by as much as 50-60%. The 17β-estradiol hormone induction increases total length and body weight, estradiol content, GIS and HIS, and also glucose content. The 17β-estradiol hormone induction shows mature development of the gonadal profile from functional male to functional female. Abstract As maroon clownfish (Amphiprion biaculeatus) is a protandrous hermaphroditic fish, feminization process with 17β-estradiol hormone can be applied to accelerate the female broodstock candidate supply for further spawning effort. This study aimed to evaluate the feminization of A. biaculeatus with 17β-estradiol hormonal induction. This study used a completely randomized design with several hormone dosage, namely P0 (without 17β-estradiol hormone induction), P1 (0.5 μg 17β-estradiol/g body), P2 (1.0 μg 17β-estradiol/g body), and P3 (1.5 μg 17β-estradiol/g body). These treatments were applied with three replications. Five fish composed of α-fish, β-fish, and three γ-fish were reared in each aquarium for 90 days with a flowing water system. The α- and β-fish were then removed, while the γ-fish was injected with hormone. Otohime pellet feed was fed three times a day until apparent satiation. The results showed that the 17β-estradiol hormone could induce 100% of the feminization process of male A. biaculeatus. The dosage of P3 obtained the lowest value percentage of red, green, blue (RGB), but showing the highest total of length and body weight (6.67±0.42 cm and 6.40±0.78 g, respectively), estradiol content (149.73±4.24 ρg/mL), GSI and HSI (0.38±0.07% and 3.59±0.49%), and glucose content (4.67±0.64 mg/dL), followed by more mature gonad profile than other treatments. This condition indicates that fish in P3 treatment has been reversed as functional female. The average survival rate for the treatment was as high as 60%. Therefore, the application of 17β-estradiol hormonal induction is effective for the feminization process in A. biaculeatus as a protandrous hermaphroditic fish.
