Biotic Interactions Are an Unexpected Yet Critical Control on the Complexity of an Abiotically Driven Polar Ecosystem
ARTICLE https://doi.org/10.1038/s42003-018-0274-5 OPEN Biotic interactions are an unexpected yet critical control on the complexity of an abiotically driven polar ecosystem Charles K. Lee et al. # 123456789 0():,; Abiotic and biotic factors control ecosystem biodiversity, but their relative contributions remain unclear. The ultraoligotrophic ecosystem of the Antarctic Dry Valleys, a simple yet highly heterogeneous ecosystem, is a natural laboratory well-suited for resolving the abiotic and biotic controls of community structure. We undertook a multidisciplinary investigation to capture ecologically relevant biotic and abiotic attributes of more than 500 sites in the Dry Valleys, encompassing observed landscape heterogeneities across more than 200 km 2. Using richness of autotrophic and heterotrophic taxa as a proxy for functional complexity, we linked measured variables in a parsimonious yet comprehensive structural equation model that explained signi ficant variations in biological complexity and identi fied landscape-scale and fine-scale abiotic factors as the primary drivers of diversity. However, the inclusion of lin- kages among functional groups was essential for constructing the best- fitting model. Our findings support the notion that biotic interactions make crucial contributions even in an extremely simple ecosystem. Correspondence and requests for materials should be addressed to S.C.C.

18th EANA Conference European Astrobiology Network Association Abstract book 24-28 September 2018 Freie Universität Berlin, Germany Sponsors: Detectability of biosignatures in martian sedimentary systems A. H. Stevens1, A. McDonald2, and C. S. Cockell1 (1) UK Centre for Astrobiology, University of Edinburgh, UK ([email protected]) (2) Bioimaging Facility, School of Engineering, University of Edinburgh, UK Presentation: Tuesday 12:45-13:00 Session: Traces of life, biosignatures, life detection Abstract: Some of the most promising potential sampling sites for astrobiology are the numerous sedimentary areas on Mars such as those explored by MSL. As sedimentary systems have a high relative likelihood to have been habitable in the past and are known on Earth to preserve biosignatures well, the remains of martian sedimentary systems are an attractive target for exploration, for example by sample return caching rovers [1]. To learn how best to look for evidence of life in these environments, we must carefully understand their context. While recent measurements have raised the upper limit for organic carbon measured in martian sediments [2], our exploration to date shows no evidence for a terrestrial-like biosphere on Mars. We used an analogue of a martian mudstone (Y-Mars[3]) to investigate how best to look for biosignatures in martian sedimentary environments. The mudstone was inoculated with a relevant microbial community and cultured over several months under martian conditions to select for the most Mars-relevant microbes. We sequenced the microbial community over a number of transfers to try and understand what types microbes might be expected to exist in these environments and assess whether they might leave behind any specific biosignatures. -

ELBA BIOFLUX Extreme Life, Biospeology & Astrobiology International Journal of the Bioflux Society A short review on tardigrades – some lesser known taxa of polyextremophilic invertebrates 1Andrea Gagyi-Palffy, and 2Laurenţiu C. Stoian 1Faculty of Environmental Sciences and Engineering, Babeş-Bolyai University, Cluj- Napoca, Romania; 2Faculty of Geography, Babeş-Bolyai University, Cluj-Napoca, Romania. Corresponding author: A. Gagyi-Palffy, [email protected] Abstract. Tardigrades are polyextremophilic small organisms capable to survive in a variety of extreme conditions. By reversibly suspending their metabolism (cryptobiosis – tun state) tardigrades can dry or freeze and, thus, survive the extreme conditions like very high or low pressure and temperatures, changes in salinity, lack of oxygen, lack of water, some noxious chemicals, boiling alcohol, even the vacuum of the outer space. Despite their peculiar morphology and amazing diversity of habitats, relatively little is known about these organisms. Tardigrades are considered some lesser known taxa. Studying tardigrades can teach us about the evolution of life on our planet, can help us understand what extremophilic evolution and adaptation means and they can show us what forms of life may develop on other planets. Key Words: tardigrades, extremophiles, extreme environments, adaptation. Rezumat. Tardigradele sunt mici organisme poliextremofile capabile să supraviețuiască într-o varietate de condiţii extreme. Suspendandu-şi reversibil metabolismul (criptobioză) tardigradele pot să se usuce sau să îngheţe şi, astfel, să supravieţuiască unor condiţii extreme precum presiuni şi temperaturi foarte scăzute sau crescute, variaţii de salinitate, lipsă de oxygen, lipsă de apă, unele chimicale toxice, alcool în fierbere, chiar şi vidul spaţiului extraterestru. În ciuda morfologiei lor deosebite şi a diversittii habitatelor lor, se cunosc relativ puţine aspecte se despre aceste organisme. -

(Ed.) Animal Biodiversity: An Outline of Higher-level Classification and Survey of Taxonomic Richness (Addenda 2013). Zootaxa, 3703, 1–82. Abstract The Arthropoda is here estimated to have 1,302,809 described species, including 45,769 fossil species (the diversity of fossil taxa is here underestimated for many taxa of the Arthropoda). The Insecta (1,070,781 species) is the most successful group, and it alone accounts for over 80% of all arthropods. The most successful insect order, Coleoptera (392,415 species), represents over one-third of all species in 39 insect orders. Another major group in Arthropoda is the class Arachnida (114,275 species), which is dominated by the Acari (55,214 mite and tick species) and Araneae (44,863 spider species). Other diverse arthropod groups include Crustacea (73,141 species), Trilobitomorpha (20,906 species) and Myriapoda (12,010 species). Key words: Classification, diversity, Arthropoda Introduction The Arthropoda, with over 1.5 million described species, is the largest animal phylum, and it alone accounts for about 80% of the total number of species in the animal kingdom (Zhang 2011a). In the last volume on animal higher-level classification and survey of taxonomic richness, 28 chapters by numerous teams of specialists were published on various taxa of the Arthropoda, but there were many gaps to be filled (Zhang 2011b). -
Anatomy of Zetela Alphonsi Vilvens, 2002 Casts Doubt on Its Original Placement Based on Conchological Characters
SPIXIANA 40 2 161-170 München, Dezember 2017 ISSN 0341-8391 Anatomy of Zetela alphonsi Vilvens, 2002 casts doubt on its original placement based on conchological characters (Mollusca, Solariellidae) Enrico Schwabe, Martin Heß, Lauren Sumner-Rooney & Javier Sellanes Schwabe, E., Heß, M., Sumner-Rooney, L. H. & Sellanes, J. 2017. Anatomy of Zetela alphonsi Vilvens, 2002 casts doubt on its original placement based on con- chological characters (Mollusca, Solariellidae). Spixiana 40 (2): 161-170. Zetela is a genus of marine gastropods belonging to the family Solariellidae (Vetigastropoda, Trochoidea). The species Zetela alphonsi Vilvens, 2002 was origi- nally described using classical conchological characters from samples obtained from deep water off Chiloé, Chile, but no other features were recorded in the original description. In the present paper, taxonomically relevant characters such as the operculum, radula, and soft part anatomy are illustrated and described for the first time from a specimen of Zetela alphonsi from a new locality, a methane seep area off the coast of central Chile. We find that many features differ substantially from other members of the genus, including several which deviate from characters that are diagnostic for Zetela. Zetela alphonsi also lacks retinal screening pigment, giving the appearance of eyelessness from gross examination. Although pigmenta- tion loss has been reported in other deep sea genera, this feature has not been re- ported in any other members of Zetela. We reconstructed a tomographic model of the eye and eyestalk, and demonstrate that a vestigial eye is still present but exter- nally invisible due to the loss of pigmentation. Based on these new morphological characters, particularly observations of the radula, we suggest that the current placement of this species in the genus Zetela should be reconsidered. -
