Worldwide Distribution Of Cave-Dwelling Chelodesmidae (Diplopoda, Polydesmida), Rodrigo Salvador Bouzan, Jackson C. Means, Kaloyan Ivanov, Rodrigo L. Ferreira, Antonio Domingos Brescovit, Luiz Felipe Moretti Iniesta
International Journal of Speleology
Chelodesmidae is one of the most species rich families within the Myriapoda. However, little is known regarding their association with caves. We provide a list of all Chelodesmidae taxa reported from caves, map their worldwide distribution, and discuss the troglomorphic features of the group. A total of 25 species and subspecies from 20 genera and 2 subfamilies have been recorded from 59 caves and cave systems in 11 countries. These numbers represent a surprisingly modest proportion (~3%) of the approximately 800 described species in the family. Records of cave-dwelling chelodesmids appear to be geographically biased with most taxa reported from …
Stygobitic Crustaceans In An Anchialine Cave With An Archeological Heritage At Vodeni Rat (Island Of Sveti Klement, Hvar, Croatia), Alessandro Montanari, Nicolas Cerveau, Barbara Fiasca, Jean-François Flot, Diana Galassi, Maurizio Mainiero, David Mcgee, Tadeusz Namiotko, Stefano Recanatini, Fabio Stoch
Stygobitic Crustaceans In An Anchialine Cave With An Archeological Heritage At Vodeni Rat (Island Of Sveti Klement, Hvar, Croatia), Alessandro Montanari, Nicolas Cerveau, Barbara Fiasca, Jean-François Flot, Diana Galassi, Maurizio Mainiero, David Mcgee, Tadeusz Namiotko, Stefano Recanatini, Fabio Stoch

A group of four amphoras found in the anchialine cave of Vodeni Rat in the Croatian island of Sveti Klement, on a rocky ledge at 24 m water depth, indicates that a freshwater source was exploited at the bottom of this karstic pit by islanders and/or passing-by sailors from the late Roman Republican Period to the Early Medieval Period. In other words, prior to the 4th–7th century CE, Vodeni Rat was not an anchialine cave but a Pleistocene karstic pit with a freshwater pool at the bottom. Seawater started to infiltrate this cavity via newly opened fissures …

Cave-dwelling organisms share different ecological and evolutionary relationships with caves. Based on these interactions, they are categorized as troglobites, troglophiles, and trogloxenes. In India, caves are meagerly explored, and thus cave study is in its infancy in India. Through the present study, we attempted to understand and model the distribution of crickets (Family Phalangopsidae), a critical group of insects - being the primary consumers in the cave ecosystems. We sampled seven caves using belt transects (N = 184; total area covered = 1294.9 m2) with 1 m width. During the survey, we encountered 818 individual crickets (116.85 ± …
The Role Of Microhabitats In Structuring Cave Invertebrate Communities In Guatemala, Gabrielle S.M. Pacheco, Marconi Souza Silva, Enio Cano, Rodrigo L. Ferreira
The Role Of Microhabitats In Structuring Cave Invertebrate Communities In Guatemala, Gabrielle S.M. Pacheco, Marconi Souza Silva, Enio Cano, Rodrigo L. Ferreira
International Journal of Speleology
Several studies have tried to elucidate the main environmental features driving invertebrate community structure in cave environments. They found that many factors influence the community structure, but rarely focused on how substrate types and heterogeneity might shape these communities. Therefore, the objective of this study was to assess which substrate features and whether or not substrate heterogeneity determines the invertebrate community structure (species richness and composition) in a set of limestone caves in Guatemala. We hypothesized that the troglobitic fauna responds differently to habitat structure regarding species richness and composition than non-troglobitic fauna because they are more specialized to live …
Species-Area Model Predicting Diversity Loss In An Artificially Flooded Cave In Brazil, Rodrigo L. Ferreira, Thais G. Pellegrini
Species-Area Model Predicting Diversity Loss In An Artificially Flooded Cave In Brazil, Rodrigo L. Ferreira, Thais G. Pellegrini
International Journal of Speleology
Subterranean environments are poorly known regarding many ecological aspects, such as community structure and its response to different disturbances. To estimate the effects of ground area lost in a limestone cave community in Southeastern Brazil, the invertebrate fauna was sampled before 76% of the cave floor was submerged by the filling of a hydroeletric power plant reservoir. Then, a 2-year monitoring was conducted. A species-area curve based on empiric data was constructed and the z-value of the species-area equation was calculated, what allowed estimating the expected cave richness after flooding comparing with data obtained during the monitoring. The results support …
Modelling The Future Spread Of Native And Alien Congeneric Species In Subterranean Habitats — The Case Of Meta Cave-Dwelling Spiders In Great Britain, Stefano Mammola
Modelling The Future Spread Of Native And Alien Congeneric Species In Subterranean Habitats — The Case Of Meta Cave-Dwelling Spiders In Great Britain, Stefano Mammola
International Journal of Speleology
The threshold zones between the epigean and hypogean environments are generally characterized by less harsh ecological conditions than deep subterranean habitats, and usually support a greater abundance of organisms. Transitional habitats such as these should be more easily colonised by alien species, especially by those possessing exaptations suitable for subterranean life. In spite of this, few studies have been conducted to unravel the ecological dynamics between native and alien species in the habitats situated at the epigean/hypogean interface. A unique test case is offered by cave-dwelling Meta orb-weaver spiders in Great Britain (Araneae: Tetragnathidae). One species, M. menardi, is …

Seasonal Dynamics And Micro-Climatic Preference Of Two Alpine Endemic Hypogean Beetles, Stefano Mammola, Elena Piano, Pier Mauro Giachino, Marco Isaia
International Journal of Speleology
Hypogean beetles generally live in stable environments, characterized by constant temperature and high relative humidity. Changes in the underground microclimatic conditions generally induce local migrations of the beetles through the hypogean environment in search of suitable microhabitats. We studied the seasonal dynamics and the micro-climatic preference of two Alpine endemic hypogean beetles - Sphodropsis ghilianii (Coleoptera, Carabidae) and Dellabeffaella roccae (Coleoptera, Cholevidae) - in the hypogean complex of Pugnetto (Graian Alps, Italy). We surveyed the two species for one year, using baited pitfall traps and measuring temperature and humidity along the two main caves. We used logistic regression mixed models …

The Economic Impact Of Commensal Rodents On Small Businesses In Manhattan’S Chinatown: Trends And Possible Causes, Anthony Almeida, Robert Corrigan, Ronald Sarno
Suburban Sustainability
Given the history of well-documented rodent infestations in New York City we were interested in assessing the economic impact of rats and mice on small businesses in The Lower East Side of Manhattan. Via mailed surveys and on-site interviews , we quantified damage to structures, loss of saleable goods and merchandise, the cost of pest-control professionals, and/or self-applied poison/traps. Overall, 16% of business (n = 76) responded to our queries. To those businesses reporting some level of rodent damage, average losses included $513 in merchandise, $726 in pest-control fees, $371 in repair costs to structure, and $125 in do-it-yourself deployment …

Using data from the Czech Republic, we studied the distribution of spiders in soils, crevice systems, scree and caves, i.e. subterranean habitats at depths spanning from 10 cm to 100 m. In total, we found 161 species. The number of species declines with increasing habitat depth, with a major drop in species richness at the depth of 10 meters. Thirteen species exhibit morphological adaptations to life in subterranean habitats. At depths greater than 10 meters, spider assemblages are almost exclusively composed of troglomorphic species. We propose a hypothesis of evolution of troglomorphisms during Quaternary climatic cycles.
