History Of

In the Carei Plain natural reserve we identified 15 terrestrial isopod species: Haplophthalmus mengii, Haplophthalmus danicus, Hyloniscus riparius, Hyloniscus transsylvanicus, Plathyarthrus hoffmannseggii, Cylisticus convexus, Porcellionides pruinosus, Protracheoniscus politus, Trachelipus arcuatus, Trachelipus nodulosus, Trachelipus rathkii, Porcellium collicola, Porcellio scaber, Armadillidium vulgare and Armadillidium versicolor. The highest species diversity is found in wetlands, while the lowest is in plantations and forests. On the Carei Plain, there are some terrestrial isopods that are normally connected with higher altitudes. Moreover, some sylvan species are present in the open wetlands. Unlike marshes, sand dunes present anthropophilic and invasive species. The diversity of the terrestrial isopods from the Carei Plain protected area is high due to the habitats? diversity and the history of this area. Thus, the composition of the terrestrial isopod communities from the area underlines its distinct particularities, emphasizing the necessity of preserving the natural habitats.

AbstractCaenorhabditis remanei was found in association with the terrestrial isopod Trachelipus rathkii at several wooded locations in southwestern Ohio. These associations were as developmentally arrested dauer larvae. The sites of association were the inner surfaces of the dorsal plates and ventral appendages. C. remanei associations also were observed with Armadillidium nasatum, Cylisticus convexus, and Porcellio scaber. They were not observed with Porcellio spinicornis even though P. spinicornis populations were intermingled with infested populations of T. rathkii. Consistent with the observed natural associations, C. remanei dauers were experimentally able to infest T. rathkii and P. scaber . Dauer larvae responded to confinement with isopods by nictating and by climbing upon these potential hosts. Experimental infestations were able to persist for at least five days. Long-term infestations were not attempted. Naturliche und experimentelle Vergesellschaftungen von Caenorhabditis remanei mit Trachelipus rathkii unde anderen terrestrischen Isopoden - An mehreren waldigen Stellen im Sudwesten von Ohio wurde Caenorhabditis remani vergesellschaftet mit dem terrestrischen Isopoden Trachelipus rathkii gefunden. Diese Assoziationen waren wie in der Entwicklung gehemmte Dauerlarven. Sie wurden an den inneren Oberflachen der Dorsalplatten und der ventralen Anhange festgestellt. Vergesellschaftungen von C. remani wurden auch mit Armadillium nasutum, Cylisticus convexus und Porcellio scaber beobachtet. Nicht beobachtet wurden sie dagegen bei Porcellio spinicornis, obwohl Populationen dieser Art mit infizierten Populationen von T. rathkii vermischt vorkamen. In Ubereinstimmung mit den beobachteten naturlichen Assoziationen konnten Dauerjuvenile von C. remani auch im Versuch T. rathkii und P. scaber befallen. Die Dauerjuvenile reagierten auf das enge Zusammensein mit den Isopoden durch Nickbewegungen und Klettern auf diese potentiellen Wirte. So ein experimenteller Befall konnte fur mindestens funf Tage bestehen. Langfristiger Befall wurde nicht versucht.

Invasive species pose one of the most serious global environmental threats. Our study aimed to examine the correlation between the proportion of invasive alien taxa and species diversity of ruderal vegetation in the urban ecosystem of Bratislava, located in Central Europe. Ruderal habitats serve as the means of spread of invasive species to seminatural and natural habitats. Twenty-six invasive taxa were recorded among the ruderal vegetation of Bratislava. The majority of the recorded invasive species were neophytes, which came from North America and represent the Asteraceae family. Half of them were introduced accidentally, whereas the remaining species were introduced deliberately. Correlation and regression analyses showed that the proportion of invasive taxa has a negative effect on the species diversity of all the analyzed syntaxa in the ruderal vegetation of Bratislava.

Abstract This paper presents first materials on the fauna and distribution of the terrestrial isopods - woodlice (Oniscidea) inhabiting the central and southern parts of Kostanay Region (Kazakhstan, Northern and Southern Turgai), located in the steppe zone. Most of the specimens of woodlice were collected in the territory of the National Nature Reserve “Altyn Dala”, a new protected area (established in 2012) and in the area of the Naurzum National Nature Reserve (established in 1931, World Heritage Site of UNESCO), on the Stipa lessingiana dry steppe. The list of woodlice includes six species (Crustacea: Isopoda: Oniscidea), belonging to five genera and three families in the study area. Four species are recorded for the first time in Kazakhstan - Desertoniscus subterraneus Verhoeff, 1930, Parcylisticus dentifrons (Budde-Lund 1885), Porcellio scaber Latreille, 1804, and Protracheoniscus major (Dollfus 1903). Distribution characteristics are provided for all of those species recorded in the study area. For the territory of Kazakhstan, according to a literature data, currently 16 species of terrestrial isopods have been recorded.

Urban Fauna

Recently, the number of alien landscape species has dramatically increased, and this could be a serious threat, not only for native species but also in cases of outbreaks for farmers. Our objective was to examine the impact of the urban environment (positive or negative) on the diversity of native species; forecast biotic homogenization or diversification of urban fauna; and determine the extent to which each of the zones are affected by invasive species. To examine the effect of urbanization, we selected 16 areas (across three urban zones and one zone in the protected area for comparison) for this study in 2015 in Nitra. We found that snails in open locations had significantly greater species diversity and abundance of individuals than in closed locations. Slightly degraded areas had the most abundant snail species, but areas heavily disturbed had high species diversity and incidence of individuals. It appears that heavily disturbed areas are suitable as new types of refuge for snails, e.g., for Helix lucorum, which was recorded in Slovakia for the first time (numerically recorded at the railway station) in 2014.

Terrestrial isopods (often referred to as sow bugs or pill bugs) are small, land-dwelling crustaceans. Because of their gentle nature, terrestrial isopods are excellent animals to have in a science classroom. There are many fun and effective classroom activities that utilize terrestrial isopods to teach science concepts, but there are multiple barriers to acquiring the large number of terrestrial isopods needed for classroom activities. Furthermore, when terrestrial isopods are brought into the classroom, the possibility exists that they will die inhumanely because finding good information on their proper care and reproduction can be difficult. Websites, books, and magazines frequently provide contradictory, inaccurate, incomplete, overly complex, and inhumane care information. To address these issues, this article explains how to set up a simple, low-maintenance, and inexpensive classroom enclosure for the terrestrial isopod species Porcellio scaber. These techniques, which I use in my classroom, produce large numbers of healthy captive-bred P. scaber. This article also presents examples of effective, hands-on classroom activities utilizing P. scaber.

Abstract P. maculata is a freshwater snail native to a wide geographical area in South America from the Rio de la Plata in Argentina and Uruguay to the Amazon in Brazil. It is commonly confused with any number of similar large apple snails, including the well-known invasive golden apple snail Pomacea canaliculata (listed among '100 of the world's worst invasive species'). Both species have been introduced to South-East and East Asia, although for many years they were not distinguished and the Asian introductions were widely identified as "golden apple snails" and the name P. canaliculata was applied to them. Due to the confusion in species identification, the history of introduction of P. maculata remains somewhat uncertain as does its invasiveness and pest potential. Much of the literature is confounded, for example, the snails illustrated by Cowie (2002) as P. canaliculata are in fact P. maculata. The majority of invasive populations in Asia appear to be P. canaliculata, often not mixed with P. maculata (Hayes et al., 2008; Tran et al., 2008) and the pest potential of P. canaliculata in such cases is clear. However, much less has been written about the invasiveness and pest potential of 'P. maculata'.

Python Bivittatus

Abstract Background Dispersal behavior is a critical component of invasive species dynamics, impacting both spatial spread and population density. In South Florida, Burmese pythons (Python bivittatus) are an invasive species that disrupt ecosystems and have the potential to expand their range northward. Control of python populations is limited by a lack of information on movement behavior and vital rates, especially within the younger age classes. We radio-tracked 28 Burmese pythons from hatching until natural mortality for approximately 3 years. Pythons were chosen from 4 clutches deposited by adult females in 4 different habitats: forested wetland, urban interface, upland pine, and agricultural interface. Results Known-fate survival estimate was 35.7% (95% CI = 18% - 53%) in the first 6 months, and only 2 snakes survived 3 years post hatching. Snakes moving through ‘natural’ habitats had higher survival than snakes dispersing through ‘modified’ habitats in the first 6- months post-hatching. Predation was the most common source of mortality. Snakes from the agricultural interface utilized canals and displayed the largest net movements. Conclusions Our results suggest that pythons may have lower survival if clutches are deposited in or near urbanized areas. Alternatively, juvenile pythons could quickly disperse to new locations by utilizing canals that facilitate linear movement. This study provides critical information about behavioral and life history characteristics of juvenile Burmese pythons that will inform management practices.
