“…Many studies reported a correlation of the temperature increase with sex determination, gametogenesis, or induction of spawning, while others have found a triggering of reproductive period after a thermal drop (Chen, 1976;Fromont and Bergquist, 1994;Corriero et al, 1998;Ereskovsky, 2000;Riesgo and Maldonado, 2008). In habitats where temperature is constant all year round, different stimuli have been proposed to play a role, such as photoperiod, wave fluctuation, rainfall, and salinity variations (e.g., Elvin, 1976;Corriero et al, 1998;Calazans and Lanna, 2019). In the deep sea, the reproductive season seems to be dependent on other environmental stimuli such as the primary productivity blooms that occur once or twice over the year (Young and Eckelbarger, 1994;Witte, 1996).…”

Boreo-arctic sponge grounds are essential deep-sea structural habitats that provide important services for the ecosystem. These large sponge aggregations are dominated by demosponges of the genus Geodia (order Tetractinellida, family Geodiidae). However, little is known about the basic biological features of these species, such as their life cycle and dispersal capabilities. Here, we surveyed five deep-sea species of Geodia from the North-Atlantic Ocean and studied their reproductive cycle and strategy using light and electron microscopy. The five species were oviparous and gonochoristic. Synchronous development was observed at individual and population level in most of the species. Oocytes had diameters ranging from 8 μm in previtellogenic stage to 103 μm in vitellogenic stage. At vitellogenic stages, oocytes had high content of lipid yolk entirely acquired by autosynthesis, with no participation of nurse cells. Intense vertical transmission of bacterial symbionts to the oocytes by phagocytosis through pseudopodia was observed, especially in late stages of oogenesis. The density of oocytes within the sponge tissue was on average 10 oocytes/mm2 across all species, higher than that of most temperate and tropical oviparous species studied elsewhere. Spermatic cysts were widespread over the tissue during early stages, or fused in larger cysts, around the canals in later stages, and occupying between 1.5 and 12% of the tissue in males. The reproductive season spanned similar periods for all Geodia spp.: from late spring to early autumn. During the reproductive peak of each species, between 60 and 90% of the population was engaged in reproduction for most species. Given the present hazards that threaten the boreo-arctic tetractinellid sponge grounds, it becomes crucial to understand the processes behind the maintenance and regeneration of populations of keystone deep-sea species in order to predict the magnitude of human impacts and estimate their ability to recover. The information provided in this study will be useful for developing adequate conservation strategies for these vulnerable deep-sea habitats.

“…As H. amboinensis is gonochoric, it is likely that some of the collected individuals were males. In addition, it is possible that other factors, such as photoperiod, tides, and food availability, may affect the onset of reproduction in sponges (Abdo et al., 2008; Abdul Wahab et al., 2014a; Calazans & Lanna, 2019; Lanna, Paranhos, Paiva, & Klautau, 2015). Sponge size, however, did not appear to be a main determinant of reproductive output in H. amboinensis (Fromont, 1994), as also observed in other sponge species, including Haliclona sp.…”

Sponges play important roles in marine ecosystems by contributing to habitat complexity and benthopelagic coupling of nutrients. Yet, the reproduction and settlement behaviors of diverse sponge species are not well understood. Here, we examined the brooding demosponge Haliclona amboinensis, which is common on shallow reefs in Bolinao, northwestern Philippines. Gravid sponges were found between the months of May and August, coinciding with warmer sea surface temperature. Sponges released parenchymella larvae from brood chambers in the mid‐morning, suggesting that light and temperature may serve as cues to initiate hatching. Larvae immediately swam toward the surface upon emergence and migrated to the bottom of the tanks 1–2 hr after release. The presence of light and crustose coralline algae induced high larval settlement. Metamorphosis proceeded rapidly in vitro, with larval cells spreading laterally on the substrate. The osculum was first visible at 3 days after settlement. The short pelagic duration of larvae in H. amboinensis promotes local recruitment and may be important for the maintenance of sponge populations in the face of disturbances.

“…An intriguing point of the present results is the rarity with which Heteropia glomerosa was found on the plates (up to 0.5 ± 0.4 specimens per plate; Figure 3G). This is an exotic species widely distributed along the Brazilian coast, occurring mainly in marinas and harbours along an extent of ~2900 km, and its reproductive effort is amongst the highest observed for sponges (Calazans & Lanna, 2019; Klautau et al ., 2020). In the studied site in Todos os Santos Bay, it is easily found along the year, colonizing ropes and a plethora of surfaces composed of different types of artificial substrates (wood, plastic, concrete and so on; Chagas & Cavalcanti, 2017; Barros et al ., 2018).…”

“…Beyond the influence of the environment, the description of temporal patterns of recruitment is an essential step to understand benthic population dynamics and structure. Therefore, in the present work, the recruitment of calcareous sponges was monitored over two years, and the putative influence of three environmental parameters on the number of recruits over time was tested: seawater temperature and photoperiod were chosen due to their previously observed effects in the reproduction of some species (Lanna et al ., 2015; Calazans & Lanna, 2019), while precipitation was chosen because it can be related to larval production (Calazans & Lanna, 2019) and due to the occurrence in the study area of marked dry (September–March) and rainy (April–August) seasons (Lessa et al ., 2009). Our study provides new insights on the recruitment dynamics of calcareous sponges from tropical areas, highlighting particularities of different species under the same environmental conditions.…”

“…Therefore, based on the observations raised by Johnson (1978) and the results obtained by Zea (1993), we hypothesized that the same may occur for calcareous sponges from other tropical regions. An argument to support this hypothesis is that variations in seawater temperature may trigger the reproduction of calcareous sponges (Lanna et al ., 2015; Calazans & Lanna, 2019). Then, it is expected that some effects may extend to their recruits.…”

Temporal variation in the recruitment of calcareous sponges (Porifera, Calcarea) in Todos os Santos Bay, tropical Brazilian coast

Recruitment is related to the occupation of the substrate by fouling organisms. It plays an important role in the maintenance and distribution of benthic populations, being under the influence of biotic and abiotic factors. In the present work, the recruitment of calcareous sponges was monitored over two years in a marina at Todos os Santos Bay, a large bay in the tropical portion of the Brazilian coast. Artificial plates were immersed, being replaced bimonthly and the potential influence of the seawater temperature, photoperiod and precipitation on the number of sponge recruits was tested. The results showed that the number of calcareous sponge recruits had significant temporal variation. Nevertheless, different species showed different patterns over time. Significant differences were observed for Sycon avus, Sycon sp. and Leucandra serrata, and the periods with the highest number of recruits were different amongst them. Sycon bellum, Paraleucilla incomposita, Leucilla sp. and Heteropia glomerosa did not show significant variation in the number of recruits over time. None of the three tested environmental factors were correlated with the number of recruits, but results indicated S. avus recruitment might be driven by seawater temperature. Our results contribute to improve the current knowledge on the dynamics of each species found on the plates and reinforce the general view that the pattern of recruitment varies greatly in Calcarea, even amongst sympatric species.
