“…The RV Atlantis surveyed the Pacific continental margin of Costa Rica from October 24th to November 5th, 2018, from the continental slope to the offshore seamounts across a subduction zone. In this region, several methane-rich seeps have been detected (Sahling et al, 2008;Levin et al, 2012Levin et al, , 2015. All sediment cores were collected by the human-occupied vehicle (HOV) Alvin equipped with mechanical, maneuverable arms.…”

“…The Costa Rican ETP comprises a chain of mountains and submarine volcanoes across the subduction zone of the Cocos and Caribbean tectonic plates. Here, there is a high diversity of microhabitats ( Lizano, 2001 ; Protti et al, 2012 ; Rojas and Alvarado, 2012 ) including methane seeps ( Sahling et al, 2008 ; Levin et al, 2012 , 2015 ). Previous studies have shown high endemism and diversity of macro- and microorganisms in this region ( Rusch et al, 2007 ; Cortés, 2008 , 2019 ; Rojas-Jiménez, 2018 ).…”

Fungal Communities in Sediments Along a Depth Gradient in the Eastern Tropical Pacific

Deep waters represent the largest biome on Earth and the largest ecosystem of Costa Rica. Fungi play a fundamental role in global biogeochemical cycling in marine sediments, yet, they remain little explored. We studied fungal diversity and community composition in several marine sediments from 16 locations sampled along a bathymetric gradient (from a depth of 380 to 3,474 m) in two transects of about 1,500 km length in the Eastern Tropical Pacific (ETP) of Costa Rica. Sequence analysis of the V7-V8 region of the 18S rRNA gene obtained from sediment cores revealed the presence of 787 fungal amplicon sequence variants (ASVs). On average, we detected a richness of 75 fungal ASVs per sample. Ascomycota represented the most abundant phylum with Saccharomycetes constituting the dominant class. Three ASVs accounted for ca. 63% of all fungal sequences: the yeast Metschnikowia (49.4%), Rhizophydium (6.9%), and Cladosporium (6.7%). We distinguished a cluster composed mainly by yeasts, and a second cluster by filamentous fungi, but we were unable to detect a strong effect of depth and the overlying water temperature, salinity, dissolved oxygen (DO), and pH on the composition of fungal communities. We highlight the need to understand further the ecological role of fungi in deep-sea ecosystems.

“…The first studies on the biology of this area reported dominance of tubeworms (Siboglinidae), clam aggregations (Vesicomyidae), mussel beds (Bathymodiolinae), and bacterial mats (Sahling et al, 2008). Levin et al (2015) found that Mound 12 has some of the highest density (~200 to more than 600 individuals per 200 cm 2 , the average size of a rock) and diversity (~26 species per rock) of deep-sea fauna on rocks from tubeworm bushes and mussel beds under active seepage among several sites in the Costa Rican Pacific margin. The faunal ensemble composition at Mound 12 shows interannual variability due to natural changes in seepage activity (Pereira et al, 2021).…”

Sexual dimorphism in the methane seep-dwelling Costa Rican yeti crab Kiwa puravida (Decapoda: Anomura: Kiwaidae)

Deep-sea chemosynthesis-based ecosystems support unique biological communities, but human impacts are an increasing threat. Understanding the life-history traits of species from deep-sea chemosynthesis-based ecosystems can help to develop adequate management strategies, as these can have impacts on ecological responses to changes in the environment. Here we examined the occurrence of sexual dimorphism in the yeti crab Kiwa puravida, an endemic species from the Costa Rican Pacific margin that aggregates at active methane seeps and depends on chemosynthetic bacteria for nutrition. The two morphological features examined included the claws, suspected to be under sexual selection and used for defense, and the carpus of the second pereopod not suspected to be under sexual selection. A total of 258 specimens, 161 males, 81 females, 16 juveniles, were collected from Mound 12 at 1,000-1,040 m depth in 2017 and 2018 and analyzed. We found that males have larger and wider claws than females, while there were no differences in carpus length. These results suggest that claw weaponry is under sexual selection in K. puravida, which is probably related to the mating system of this deep-sea species. This is the first attempt to study the reproductive biology of K. puravida, and additional observations will be necessary to shed more light on this matter.
