“…Morais & Bellwood, 2020 ). We thus provide a detailed comparison of the biomass and productivity of diurnal versus nocturnal reef fishes within a coral reef system, while simultaneously exploring differences between exposed and sheltered locations—an important determinant for community structure which may also shape the relative intensity of ecological functions (Bronstein & Loya, 2014 ; Davis et al, 2021 ; Depczynski & Bellwood, 2005 ; Fulton & Bellwood, 2005 ; Valenzuela et al, 2021 ). By scaling individual contributions to energetic or nutrient flows, we provide insights into the role of diurnal versus nocturnal organisms in storing or moving energy or material within or between ecosystems: key reef‐scale ecosystem processes (Bellwood et al, 2019 ).…”

Daytime (diurnal) ecological studies far outpace night-time (nocturnal) studies (Gaston, 2019;Park, 1940). This diurnal research bias in ecology, likely driven by a plethora of logistical challenges, is exacerbated in submerged aquatic systems where light is naturally scarce, and where organisms must be studied in situ. Coral reefs typify this disparity resulting in a fragmentary understanding of the ecological functions performed by coral reef organisms during the nocturnal period. This is true even for major biological components

The aggregation of planktivorous fish on the windward side of island has been observed by Hamner et al 146 that described a “wall of mouth” composed by planktivorous fish picking up zooplankton before it reaches the reef 146 , 147 . Second, the water is much more turbid leeward than windward where visual predators concentrate.…”

Tropical marine ecosystems are highly biodiverse and provide resources for small-scale fisheries and tourism. However, precise information on fish spatial distribution is lacking, which limits our ability to reconcile exploitation and conservation. We combined acoustics to video observations to provide a comprehensive description of fish distribution in a typical tropical environment, the Fernando de Noronha Archipelago (FNA) off Northeast Brazil. We identified and classified all acoustic echoes into ten fish assemblage and two triggerfish species. This opened up the possibility to relate the different spatial patterns to a series of environmental factors and the level of protection. We provide the first biomass estimation of the black triggerfish Melichthys niger, a key tropical player. By comparing the effects of euphotic and mesophotic reefs we show that more than the depth, the most important feature is the topography with the shelf-break as the most important hotspot. We also complete the portrait of the island mass effect revealing a clear spatial dissymmetry regarding fish distribution. Indeed, while primary productivity is higher downstream, fish concentrate upstream. The comprehensive fish distribution provided by our approach is directly usable to implement scientific-grounded Marine Spatial Planning.

“…Nevertheless, if sampling is insufficient, there is still the risk of obtaining a skewed dataset. Other reasons may be ontogenetic shifts in habitat use (Fobert et al ., 2020; Galaiduk et al ., 2017; Lecchini & Galzin, 2005; Valenzuela et al ., 2021) or reproduction ( e.g ., spawning aggregations, sexual reversion) (Domeier & Colin, 1997; Nemeth et al ., 2020), which directly affects the size structure of the population, therefore the habitat where the biological samples are obtained influences the size range and maturity stage of the organisms.…”

This study aimed to describe updated information on the basic reproductive biology of Sphoeroides annulatus females and potential use of the gonadosomatic index I G ð Þ as input data to assess length at 50% maturity (L 50 ) and identify the breeding season. FromApril 2014 to December 2015, 767 females were analysed along the north-west coast of the Mexican Pacific Ocean. Both immature and mature females were represented in the total length (L T ), which ranged from 81 to 440 mm, and the smallest mature female was 92 mm (new record for the species). Gonadal maturity phases were assigned through histological analysis. A I G threshold value I cut
