Abstract:
... While noncovalent interactions between graphene derivatives and biosystems are extensively studied, less knowledge about their covalent multivalent interactions at biointerfaces is available. Due to the affinity of boronic acids towards cis-diol bearing biosystems, graphene sheets with this functionality were synthesized and their covalent interactions with the bacteria and nematode were investiga ...

Abstract:
... The rigours of the daily lives of insects sometimes lead to minor injuries and wounds, which must be healed to avoid entry of pathogens and to resume normal function. Such healing requires energy, which must be diverted from other bodily reserves. What happens if energy reserves are already low, as would occur in individuals coping with internal parasites? This question is addressed in the presemt ...

Abstract:
... The subterranean termite Reticulitermes flavipes (Kollar, 1837) (Isoptera: Rhinotermitidae) occurs throughout the eastern USA and populations have been found as far west as Oregon. As with other termites, eastern subterranean termites live in colonies composed of workers, soldiers and reproductives. The blind, wingless workers, which are only between 3 and 4 mm long, feed on wood and can cause ser ...

Abstract:
... There is no single feature to distinguish free-living soil nematodes from freshwater nematodes, also because all free-living nematodes are essentially aquatic. This notwithstanding, by examining the frequencies of some characters of 1141 European species, differences of qualitative/quantitative characters between soil and freshwater nematodes were found. In particular, aquatic and semi-aquatic spe ...

Yet, the overall consequences of land‐use changes on belowground biodiversity at large scales remain insufficiently explored. Furthermore, the effects of conversion on different organism groups are usually determined at the taxonomic level, while an integrated investigation that includes functional and phylo ...

Abstract:
... The distribution of parasites within host populations and communities, and the mechanisms responsible for these patterns, are poorly understood aspects of wildlife parasitology. Here, we evaluate the influence of the average abundance of endoparasite variance, using endoparasites of lizards from the Caatinga domain (semiarid region), north-eastern Brazil. We hypothesized that, due to the high numb ...

Abstract:
... Contrary to a general rule of stable isotope trophic discrimination, parasites show great variation in isotope discrimination from their host muscle tissues. One of the possible mechanisms is that isotopic variation among host tissues may cause apparent deviation from the actual isotope discrimination between a parasite and a given host tissue consumed by the parasite. To test this possibility, we ...

Abstract:
... The velocity of a traveling invasive front of a pest can be determined through the moment generating function associated to the so-called contact distribution of the dispersal process. This distribution captures the non-local character of the underlying spatial component in an invasion event. In this paper we present a spatial model for the spread of alfalfa stem nematodes, using a Gaussian contac ...

Abstract:
... The reproductive system of the hermaphroditic nematode C. elegans consists of a series of contractile cell types—including the gonadal sheath cells, the spermathecal cells and the spermatheca–uterine valve—that contract in a coordinated manner to regulate oocyte entry and exit of the fertilized embryo into the uterus. Contraction is driven by acto-myosin contraction and relies on ...
