Comparative genomics analyses indicate differential methylated amine utilization trait within members of the genus Gemmobacter [PDF]

Environmental Microbiology Reports, Volume 13, Issue 2, Page 195-208, April 2021., 2021
Summary Methylated amines are ubiquitous in the environment and play a role in regulating the earth's climate via a set of complex biological and chemical reactions. Microbial degradation of these compounds is thought to be a major sink. Recently we isolated a facultative methylotroph, Gemmobacter sp. LW‐1, an isolate from the unique environment Movile

Niphargus-Thiothrix associations may be widespread in sulphidic groundwater ecosystems: evidence from southeastern Romania. [PDF]

Mol Ecol, 2014
Abstract Niphargus is a speciose amphipod genus found in groundwater habitats across Europe. Three Niphargus species living in the sulphidic Frasassi caves in Italy harbour sulphur‐oxidizing Thiothrix bacterial ectosymbionts. These three species are distantly related, implying that the ability to form ectosymbioses with Thiothrix may be common among ...

A new cave-dwelling species of the genus Geophilus Leach, 1814 (Chilopoda: Geophilomorpha) from the chemoautotrophic-based Movile Cave (Southern Dobrogea, Romania) [PDF]

The European Zoological Journal
Geophilus zagreus sp. nov., a troglomorphic geophilid endemic to the Movile Cave sulfidic groundwater ecosystem, is described and illustrated. It is distinguished from other European Geophilus species by a high number of coxal pores on the ventral side of the coxa of the last pair of legs.

Methanotrophy in Movile Cave [PDF]

Movile Cave is an isolated cave ecosystem that receives no input of photosynthetically fixed carbon. Instead, carbon is primarily fixed through light- independent bacterial processes such as chemolithoautotrophy and methanotrophy. Distinctive microbial floating mats appear at the surface of groundwater flooding the cave, at the redox interface between ...

Chronogaster troglodytes sp. n. (Nemata : Chronogasteridae) from Movile Cave, with a review of cavernicolous nematodes [PDF]

, 1994
#Chronogaster troglodytes$ sp. n. (Nemata : chronogasteridae) est décrit comme le premier véritable nématode cavernicole, récolté dans la caverne de Movile, en Roumanie. Cette espèce est adaptée à la survie dans le feutrage d'hyphes fongiques flottant à la surface d'eaux thermo-minérales riches en hydrogène sulfuré.

Niche specialisation and aerobic trace gas utilising microbes in Movile Cave

Karst Science Days Symposium Proceedings
The isolation of cave ecosystems from dynamic surface environments gives them relatively stable conditions, allowing underlying features of the cave, such as geochemistry, hydrology and microbial biogeochemical cycling to be the driving influences on the composition of microbial niches within cave ecosystems. The transfer of gases, either geological or

Cave Thiovulum (Candidatus Thiovulum stygium) differs metabolically and genomically from marine species. [PDF]

ISME J, 2023
Thiovulum spp. (Campylobacterota) are large sulfur bacteria that form veil-like structures in aquatic environments. The sulfidic Movile Cave (Romania), sealed from the atmosphere for ~5 million years, has several aqueous chambers, some with low ...

Evaluating and mitigating locally and nationally variable food security dynamics in Guatemala through participatory causal loop diagram building

System Dynamics Review, Volume 39, Issue 3, Page 239-276, July/September 2023., 2023
Abstract Various methods have been proposed to analyze national trends of malnutrition and food insecurity; however, these methods often fail to consider regional specificities that drive national food security dynamics. This case study seeks to close this gap through the novel use of participatory causal loop diagrams (CLDs) to analyze the ...

Swap It on WhatsApp: The Moral Economy of Informal Online Exchange Networks in Contemporary Cuba

The Journal of Latin American and Caribbean Anthropology, Volume 27, Issue 1-2, Page 80-100, June 2022., 2022
Abstract The inhabitants of Cuba's capital, Havana, are using semipublic group chats on messaging applications such as WhatsApp and Telegram to access food, hygiene products, medication, and other basic necessities during times of scarcity. This has been especially prevalent during the COVID‐19 pandemic. Such chat groups created digital spaces in which
