Exposure of a facultative air breather, Hoplosternum littorale, to 12.5, 25, and 37.5% of the water soluble fraction (WSF) of Urucu crude oil, resulted in a rapid increase in air-breathing frequency (ABF) sustained over the 45 min period of exposure. Following 4 h exposure to a graded increase in WSF up to 50%, there was no significant affect on haematocrit, or plasma [Na+] and [K+]. Crude oil ...

Two new species of Henneguya (Myxozoa) were described from specimens collected on the gills of Hoplosternum littorale (Hancock, 1828) (Callichthyidae) and Cyphocharax gilbert (Quoy and Gaimard, 1824) (Curimatidae), from Guandu River, State of Rio de Janeiro, Brazil. The species described were compared with the related species of the genus. The new species of Henneguya parasitic on H. littorale ...

As I walked into an unassuming hotel restaurant in Chicago during the ALA Annual Conference June, had my eyes peeled for a colleague was meeting. Instead, spotted icon. Quickly glancing to right, spot woman who looks just like Judy Blume, enjoying coffee at quiet table. Upon finding tablemates around corner, silently squealed, “Is that Blume?”

The so-called diluted-random-cluster model may be viewed as a random-cluster representation of the Blume–Capel model. It has three parameters, a vertex parameter a, an edge parameter p, and a cluster weighting factor q. Stochastic comparisons of measures are developed for the ‘vertex marginal’ when q ∈ [1, 2], and the ‘edge marginal’ when q ∈ [1,∞). Taken in conjunction with arguments used earl...

The relationship between Popper spaces (conditional probability spaces that satisfy some regularity conditions), lexicographic probability systems (LPS’s) [Blume, Brandenburger, and Dekel 1991a; Blume, Brandenburger, and Dekel 1991b], and nonstandard probability spaces (NPS’s) is considered. If countable additivity is assumed, Popper spaces and a subclass of LPS’s are equivalent; without the as...

The MADS-box genes of land plants are extensively diverged to form a superfamily and are important in various aspects of development including the specification of floral organs as homeotic selector genes. The closest relatives of land plants are the freshwater green algae charophyceans. To study the origin and evolution of land plant MADS-box genes, we characterized these genes in three charop...
