Travaux de l'Institut de Speologie Emile Racovitza, 2020 41 species of Oniscidea are recorded from Dobrogea, a crossroad of the Western, Southern and, especially, Northern and Southern spreading areas: a third of the species are endemic with Southern Dobrogea harboring a quarter of the endemic species ...

Seasonal total methane depletion in limestone caves. [PDF]
Sci Rep, 2017 Methane concentration in caves is commonly much lower than the external atmosphere, yet the cave CH4 depletion causal mechanism is contested and dynamic links to external diurnal and seasonal temperature cycles unknown.

Standing genetic variation as a potential mechanism of novel cave phenotype evolution in the freshwater isopod, Asellus aquaticus. [PDF]
Evol Dev, 2023 An orange eye phenotype, hidden within cave populations (masked by absence of pigment), was uncovered through crossing cave populations with surface populations. A similar orange eye phenotype can be found within surface populations suggesting that orange alleles within the cave populations originated from standing variation in the founding surface ...

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.

METHYLATED AMINE-UTILISING BACTERIA AND MICROBIAL NITROGEN CYCLING IN MOVILE CAVE [PDF]
, 2014 Movile Cave is an unusual, isolated ecosystem which harbours a complex population of microorganisms, fungi and endemic invertebrates. In the absence of light and with no fixed carbon entering the cave, life is sustained by non-phototrophic ...

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 ...

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 ...
