Islands are pieces of land entirely surrounded by sea on which terrestrial and marine organisms live as little as a few metres apart. Yet, in contrast to terrestrial species, marine species have attracted little attention in studies of island theory. The experimental and conceptual origins of this dichotomy date back to the 1970s, although the apposition has softened in the early 2000s, in part a consequence of phylogeographic analyses and the discovery of new marine environments. Here, I explore the possible range of island and island-like settings in the marine realm and find good evidence, albeit in short supply, for integrating marine with terrestrial perspectives during the current transition from equilibrium to general dynamic models of island biogeography. This integration of marine systems into island theory will be facilitated by three advances: (1) development of many descriptive marine studies to reduce the current deficit, (2) design of rigorous comparative studies within and across realms, and (3) modification of conceptual models to unite seemingly disparate situations, for example describing islands in terms of ecological-evolutionary processes. Marine island biogeography is in its infancy; it may present situations that are uncommon in the existing literature, but not rare in nature, and thus contribute substantially to the new dynamic outlook on a halfcentury-old theme.

“…Lakes like Lake Mogilnoe on Kildin Island in the Barents Sea (Fokin et al 2004;Strelkov et al 2014) and the Big Rios and Crespo (2004) Soda Lake in the USA (Cloern et al 1983) (Fig. 6), demonstrate that surface water layers may not have a salinity < 3 g dm − 3 , but may instead be hyposaline sensu Hammer (1993;3-20 g dm − 3 ).…”

Unique Pit Lake Created in an Opencast Potassium Salt Mine (Dombrovska Pit Lake in Kalush, Ukraine)

et al. 2018

We studied the physicochemical and biological characteristics of the Dombrovska pit lake in Ukraine. The lake formed in an abandoned opencast potassium salt mine and is one of the most saline inland water bodies in the world. It is 85 m deep (November 2015) and an annual inflow of about 2 Mm 3 of water. The lake has two distinct layers. The mesohaline surface (0-5 m) layer is well oxygenated and slightly alkaline (pH = 7.5-8.8). Its mineralization, expressed as dry mass, was 50-134 g dm − 3 , and its electrical conductivity (EC) was 58-134 mS cm − 1 . The underlying layer consists of hypersaline water with low amounts of dissolved oxygen, a neutral pH (6.7-7.4), high mineralization (179-420 g dm − 3 ), high EC (169-215 mS cm − 1 ), and higher concentrations of major anions and cations (except Ca 2+ ) and nutrients than the overlying water. The vertical relationship between major ions and metals and the future salinity of the lake are discussed. In terms of zooplankton, in July we found living specimens of the rotifer Brachionus plicatilis and the ciliates Paradileptus elephantinus and Tindinnidium sp. as well as dead rotifers, cladocerans, and copepods (in total, 19 species), but only live B. plicatilis and 9 dead species in November. In the littoral part of the pit lake, we found the diatoms Nitzschia pusilla and some Halamphora species (H. borealis, H. tenerrima, H. acutiuscula), which favour highly saline waters.

“…The connection between the marine lakes and the outer marine environment strongly influences the communities inhabiting these lakes (Saitoh et al 2011). Lakes with a limited connection tend to house a smaller number of species including numerous endemics (Becking et al 2013a(Becking et al , 2013b(Becking et al , 2016Strelkov et al 2014), whereas more connected lakes tend to house more species, but with a greater compositional similarity to open sea habitat. Lake size also influences the number of species, with larger lakes housing a higher number of species than smaller ones (Becking et al 2013b).…”

Geographical location and habitat predict variation in prokaryotic community composition of Suberites diversicolor

et al. 2020

Purpose: Marine lakes are unique habitats that house diverse assemblages of benthic and planktonic organisms including endemic species. In this study, we aimed to assess to what extent geographical location (Berau versus Papua) and the degree of marine lake connectivity (relatively open versus closed) to the surrounding marine environment structures the prokaryotic community composition of the sponge species Suberites diversicolor. Methods: Sponge specimens were sampled in five marine lakes in Borneo and Papua and one open sea habitat in Taiwan. Result: Prokaryotic communities of S. diversicolor were dominated by members assigned to the Proteobacteria (particularly Alphaproteobacteria and Gammaproteobacteria) and Cyanobacteria, which together made up from 78 to 87% of sequences in all samples. The dominant operational taxonomic units (OTUs) in most samples, OTUs 1 and 3, were both assigned to the alphaproteobacterial order Rhodospirillales with OTU-1 dominant in the marine lakes of Berau and Papua and OTU-3 in Taiwan. OTU-3 was also largely absent from Papuan samples but present in all Berau samples. Compositionally, S. diversicolor samples clustered according to geographical location with the main axis of variation separating marine lake samples collected in Berau from those collected in Papua and the second axis of variation separating open sea samples collected in Taiwan from all marine lake samples. In addition, our results suggest that the degree of lake connectivity to the open sea also influences prokaryotic composition. Conclusion: Although previous studies have shown that sponge-associated microbial communities tend to be stable across different geographical and environmental gradients, in the present study, both geography and local environmental conditions were significant predictors of variation in prokaryotic community composition of S. diversicolor.
