“…The sea urchin densities observed in this study are relatively high compared to recent data from several other P. kauderni population sites, but consonant with historical data from this and other P. kauderni population sites (EC-PREP, 2005;Moore et al, 2019a;Ndobe et al, 2013aNdobe et al, , 2013bNdobe et al, 2018a). With regards to microhabitat other than Diadema, two of the sites (the ferry harbour and Teluk Lalong harbour) are highly degraded sites, with no other benthic organisms known to serve as P. kauderni microhabitat seen during the survey.…”

The Banggai cardinalfish Pterapogon kauderni is the Indonesian national marine ornamental fish mascot, and an object of national and international conservation concern. The endemic population of this species is limited to the Banggai Archipelago in Central Sulawesi, Indonesia and a few nearby islands in North Maluku. In addition, introduced populations have become established, mainly along ornamental fish trade routes. The National Action Plan for Banggai Cardinalfish Conservation (NAP-BCFC) calls for monitoring and management of all P. kauderni populations. A survey of the Luwuk introduced P. kauderni population was carried out in October 2021. Data were collected at three sites with established P. kauderni populations: the ferry harbour, public harbour (Teluk Lalong) and a recreational area on the nearby coast (Kilo 5). P. kauderni were recorded by microhabitat association and size class (recruits, juveniles, adults). Data collected were compared with data from previous surveys where available. With the exception of one group in a sea anemone at Kilo 5, all P. kauderni were associated with Diadema sea urchins (D. setosum at all sites; D. savignyi at Kilo 5). At Kilo 5 P. kauderni the population structure indicates the possible capture of market-sized juveniles. Overall abundance was also lower compared to the polluted but unfished harbours. The proportion of recruits was significantly negatively correlated with the ratio of adult P. kauderni to Diadema urchins. The results will inform regional legislation currently in preparation to support sustainable management of P. kauderni populations, habitat and microhabitat in Central Sulawesi, as well as contributing to NAP-BCFC targets.Keywords:Banggai cardinalfishEndangered speciesDiademaMicrohabitat,MonitoringOrnamental fisheryLocal regulation

“…The importance of diadematid sea urchins is reflected in local names such as the Bajo bebese tayung meaning small sea urchin fish (Ndobe et al, 2005). At least two (Ndobe et al, 2018b) and possibly more (Moore et al, 2019a) species of the genus Diadema serve as P. kauderni microhabitat. Association of P. kauderni with the genus Echinothrix also appears to be relatively common (Moore, 2019;Moore et al, 2019a;Ndobe et al, 2013aNdobe et al, , 2018b, while association with Astropyga has been reported when this genus was present (Moore, 2019;Moore et al, 2019a;Ndobe et al, 2018b;Talbot et al, 2013).…”

Abstract. The Banggai cardinalfish Pterapogon kauderni is a species of national and international conservation concern. Established in November 2019, the Banggai marine protected area (MPA) in Central Sulawesi, Indonesia covers most of the endemic range of this ornamental fish. The third repeat survey (T2 monitoring) under the National Action Plan for Banggai Cardinalfish Conservation (NAP-BCFC) was carried out in October 2019 at eight sites in the Bokan Kepulauan region within the MPA. The T2 monitoring used the standard NAP-BCFC belt transect method. Data were collected on P. kauderni abundance (by size class: recruits, juveniles, adults) and microhabitat (sea urchins, sea anemones, hard corals, and others). Data were evaluated with respect to the T0 (2017) survey and T1 (2018) monitoring at the same sites, as well as previous surveys in 2004 (2 sites) and 2012 (4 sites). The data show wide between-site variation in P. kauderni and microhabitat parameters, with one subpopulation at very high risk of extirpation. Trends included declines over time in P. kauderni, sea urchin and sea anemone abundance, with an increase since 2017 in hard coral microhabitat use by adult P. kauderni. We recommend evaluation of other P. kauderni populations in Bokan Kepulauan and specific site or zone-based actions. However, we conclude that the most urgent priority for P. kauderni conservation in Bokan Kepulauan is protection of key microhabitat through a moratorium on sea urchin and sea anemone collection in P. kauderni habitat.

“…On a much finer scale, D. setosum and D. savignyi show some differences in the microhabitat they occupy 85 , but they can often be found in mixed aggregations 44,84 . D. clarki is known from only part of the range of D. setosum and D. savignyi in Japan 38 , Indonesia 39 , and the Marshal Islands 33 , but this species had been synonymized by Mortensen 86 with D. setosum after its original description by Ikeda 87 and was only resurrected in 2014 by Chow et al 37 . It is, thus, likely to be much more widespread.…”

Slow evolution under purifying selection in the gamete recognition protein bindin of the sea urchin Diadema

Bindin is a sperm protein that mediates attachment and membrane fusion of gametes. the mode of bindin evolution varies across sea urchin genera studied to date. in three genera it evolves under positive selection, in four under mostly purifying selection, and in one, results have been mixed. We studied bindin evolution in the pantropical sea urchin Diadema, which split from other studied genera 250 million years ago. We found that Diadema bindin is structurally similar to that of other genera, but much longer (418 amino acids). In seven species of Diadema, bindin evolves under purifying selection, more slowly than in any other sea urchin genus. only bindin of the recently rediscovered D. clarki shows evidence of positive selection. As D. clarki is sympatric with D. setosum and D. savignyi, positive selection could arise from avoidance of maladaptive hybridization. However, D. setosum and D. savignyi overlap in the Indo-West Pacific, yet their bindins show no evidence of positive selection, possibly because the two species spawn at different times. Bindin in the East Pacific D. mexicanum, the West Atlantic D. antillarum, the east Atlantic D. africanum, and the Indo-Pacific D. paucispinum also evolves slowly under purifying selection.
