Is foraging innovation lost following colonization of a less variable environment? A case study in surface- vs. cave-dwelling Asellus aquaticus. [PDF]
Ecol Evol, 2020 We showed that cave‐adapted freshwater isopod Asellus aquaticus did not lose its ability to recognize and even prefer surface food after at least 60,000 years of isolation in the cave . This result suggest that adaptation to a highly specialized and stable habitat does not necessary include a decrease in behavioral innovativeness.

Parallel morphological evolution and habitat-dependent sexual dimorphism in cave- vs. surface populations of the Asellus aquaticus (Crustacea: Isopoda: Asellidae) species complex. [PDF]
Ecol Evol, 2021 Surface‐dwelling species that repeatedly and independently colonized caves such as Asellus aquaticus provide unique models to study parallel evolution. We measured and analyzed 17 functional morphological traits on 656 individuals from 15 cave and surface populations. We found that besides the expected habitat‐related morphological changes habitat type

Comparative Embryology and Transcriptomics of Asellus infernus, an Isopod Crustacean From Sulfidic Groundwater. [PDF]
Evol DevIndividuals of Asellus infernus, a sulfidic subterranean population of the Asellus aquaticus species complex from southeastern Romania (left) and surface individuals of A. aquaticus (right). Extreme differences in phenotype are seen comparing the subterranean and surface individuals as adults (top panels) and as embryonic samples (bottom panels ...

Life without light: microbial diversity and evidence of sulfur- and ammonium-based chemolithotrophy in Movile Cave [PDF]
The ISME Journal, 2009 Abstract Microbial diversity in Movile Cave (Romania) was studied using bacterial and archaeal 16S rRNA gene sequence and functional gene analyses, including ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO), soxB (sulfate thioesterase/thiohydrolase) and amoA (ammonia monooxygenase). Sulfur oxidizers from both Gammaproteobacteria

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

A new cave Pseudoscorpion from the region of Mangalia (Romania): Chthonius (Ephippiochthonius) borissketi n. sp. (Chthoniidae, Pseudoscorpiones) [PDF]
Archives of Biological Sciences, 2014 Only two species of Chthonius (Ephippiochthonius) (Chthoniidae) are presently known from Dobruja, Romania. Among these one should mention Chthonius (Ephippiochthonius) tetrachelatus (Preyssler) (not endemic) and C.

Molecular Ecology, Volume 30, Issue 14, Page 3530-3547, July 2021., 2021 Abstract Organisms well suited for the study of ecotype formation have wide distribution ranges, where they adapt to multiple drastically different habitats repeatedly over space and time. Here we study such ecotypes in a Crustacean model, Asellus aquaticus, a commonly occurring isopod found in freshwater habitats as diverse as streams, caves and lakes.
