“…Such trade-offs will be more likely to occur when disturbances coincide with key reproductive processes such as gametogenesis. For example, at Gorgona Island, P. damicornis begins gamete production in February (coinciding with extreme low-tide events), but in May (when gamete maturation occurs) colonies with partial bleaching do not produce gametes (Castrillón-Cifuentes et al 2015).…”

“…However, in cases in which hermaphrodites are found to be extremely rare, the species is usually considered as exhibiting stable gonochorism (Giese 1974;Harrison 2011;Glynn et al 2017). The occurrence of the three sexual morphs can also be found within colonies (Tomascik and Sander 1987;Guest et al 2012;Castrillo ´n-Cifuentes et al 2015). For example, Guest et al (2012) found episodic occurrences of hermaphroditism in Diploastrea heliopora, in which colonies contained male, female, and a low proportion of 'co-sexual' polyps (i.e., containing both oocytes and spermaries on the same mesentery).…”

“…However, exceptions to these systematic trends are evident in certain coral species that exhibit a more complex sexual pattern (Baird et al 2009;Harrison 2011), including the occurrence of hermaphroditism in a species otherwise considered to be gonochoric. Such atypical sexual systems have been recorded in various species in which different populations are either gonochoric or hermaphroditic (Glynn et al 1994), with some populations containing a mixture of females, males, and hermaphrodites (Soong 1991;Santiago-Valentı ´n et al 2015), or in which a mixture of the three sexual morphs exist within the same colony (Tomascik and Sander 1987;Harrison 2011;Guest et al 2012;Castrillo ´n-Cifuentes et al 2015;Glynn et al 2017). Species belonging to the family Fungiidae are among those exhibiting atypical sexuality (Harrison 2011).…”

A unique reproductive strategy in the mushroom coral Fungia fungites

et al. 2020

The vast majority of scleractinian corals are either simultaneous hermaphrodites or gonochoric. Exceptions to these are rare. Nevertheless, species belonging to the family Fungiidae are known to exhibit a wide variety of reproductive strategies. We examined the reproductive ecology of the mushroom coral Fungia fungites in Okinawa. Our study was conducted as part of a long-term, wide-ranging project (2009-2010 and 2013-2017) which explored the unique reproductive strategies of several species belonging to the family Fungiidae. Here we report the co-occurrence of males, females, and hermaphrodite individuals in a longterm monitored population of the reproductively atypical brooder coral F. fungites within the family Fungiidae. F. fungites status as a single-polyped solitary coral, was used to perform manipulative experiments to determine the degree

“…2) Settlement of sexually produced larvae and their subsequent juvenile recruitment also contribute to repopulate affected areas of the reef. While it has been difficult to observe coral larval settlement on artificial substrates in the eastern tropical Pacific (Medina-Rosas, et al, 2005; López-Pérez, et al, 2007), including Gorgona Island (Lozano-Cortés and Zapata, 2014), histological evidence clearly indicates that gonad maturation and sexual reproduction indeed occur in ETP coral populations (Glynn, et al, 2017b), including those at La Azufrada reef (Castrillón-Cifuentes, et al, 2015). In fact, juvenile colonies are often seen on the bare carbonate pavement on the reef flat of La Azufrada reef suggesting that recruitment of sexually-produced colonies is occurring (Jaramillo-González, 2012).…”

Coral reefs are highly dynamic ecosystems often affected by diverse natural disturbances. However, dramatic declines in coral cover during recent decades raise the question of whether such declines are due to increasing anthropogenic impacts. To this end, the dynamics of coral and algal cover were studied based on data collected between 1998-2014 from 20 fixed 10-m transects at two depths in two sites of La Azufrada, a coral reef free of local human impacts, located at Gorgona Island, Colombia. Coral cover declined from 66.9 % in 1998 to 39.4 % in 2008, but then increased to 50.7 % in 2014. Fleshy and turf algae were low between 1998-2004, increased to 49.5 % in 2007, and then declined to < 33.0 %. Crustose coralline algae were lowest until 2009 when they increased as fleshy and turf algae decreased. Temporal variation was different between depths with shallow areas exhibiting major declines in coral cover until 2008 but a significant recovery since then. In contrast, coral cover in deep areas declined only slightly. Prolonged subaerial exposure of corals during extreme low tides appears to drive a cycle of coral disturbance and recovery. Coral growth makes the reef flat prone to subaerial exposure, after which corals bleach, die and are colonized by filamentous turf and fleshy algae. Sea urchins and herbivorous fishes increase their abundance in response to increased algal cover and control algal growth, leaving the substrate covered by crustose coralline algae and making it suitable for settlement by sexually-produced coral larvae. Fragmentation by both physical and biological agents (such as corallivores) enhances coral recruitment and the reef enters a coral recovery phase. Although this reef is resilient to subaerial exposure because it is protected from anthropogenic perturbations, increasing threats from global climate change may compromise its future resilience. © 2017.

Dinámica temporal de la cobertura de corales y algas y sus impulsores en un arrecife coralino de Isla Gorgona, Colombia (Pacífico Tropical Oriental) ResumenLos arrecifes coralinos son ecosistemas altamente dinámicos, a menudo afectados por diversas perturbaciones naturales. Sin embargo, descensos dramáticos en la cobertura coralina durante décadas recientes llevan a preguntar si tales descensos han sido causados por crecientes impactos antropogénicos. Con este fin, la dinámica de la cobertura de coral y algas se estudió a partir de datos recolectados entre 1998-2014 de 20 transectos fijos de 10 m a dos profundidades en dos sitios de La Azufrada, un arrecife coralino libre de impactos humanos locales, situado en Isla Gorgona, Colombia. La cobertura coralina disminuyó de 66,9 % en 1998 a 39,4 % en 2008, pero luego aumentó a 50,7 % en 2014. La cobertura de algas carnosas y de césped fue baja entre 1998-2004, aumentó a 49,5 % en 2007 y luego disminuyó a < 33,0 %. Las algas coralinas incrustantes f...
