We report two species of Eucinetidae, Nycteus oviformis (LeConte) and Nycteus punctulatus (LeConte), new to New Brunswick, Canada and confirm the presence of Nycteus testaceus (LeConte). Nycteus oviformis is newly recorded from the Maritime provinces. Additional locality data are provided for Eucinetus haemorrhoidalis (Germar) and Eucinetus morio LeConte. Five species of Scirtidae, Cyphon rufic...
We established replicated experimental populations of the annual plant Clarkia pulchella to evaluate the existence of a causal relationship between loss of genetic variation and population survival probability. Two treatments differing in the relatedness of the founders, and thus in the genetic effective population size (Ne ), were maintained as isolated populations in a natural environment. Af...
This study was performed to determine infection and pathologies of the parasites (Myxobolus cyprini Lamproglena pulchella) on three different fish species (Barbus lacerta, Capoeta trutta umbla) caught in Wildlife. The for this were transported laboratory accordance with ethical rules investigated parasites. According results, two parasite identified. Myxobolus found soft tissue pectoral fins as...
The pelidnotine scarabs (Scarabaeidae: Rutelinae: Rutelini) are a speciose, paraphyletic assemblage of beetles that includes spectacular metallic species ("jewel scarabs") as well as species that are ecologically important as herbivores, pollinators, and bioindicators. These beetles suffer from a complicated nomenclatural history, due primarily to 20th century taxonomic and nomenclatural errors...
The seed bank dynamics of the three co-occurring obligate-seeder (i.e. fire-sensitive) Proteaceae species, Banksia ericifolia, Banksia marginata and Petrophile pulchella, were examined at sites of varying time since the most recent fire (i.e. plant age) in the Sydney region. Significant variation among species was found in the number of cones produced, the position of the cones within the canop...
Only six species of Microvelia have been recorded from Colombia up to the present, namely M. ancona, M. hinei, M. leucothea, M. longipes, M. panamensis, and M. pulchella. Microvelia inguapi sp. n. and M. piedrancha sp. n. are herein described and compared with similar species. An identification key to the Colombian species of Microvelia is presented.
BACKGROUND Gaillardia grandiflora Hort. ex Van Houte and Gaillardia pulchella Foug are flowering plants widely cultivated in Egypt for their ornamental value. Previous reports demonstrated that sesquiterpene derivatives represent the major compounds in both species. Moreover, only few flavones were identified from genus Gaillardia and few studies on the cytotoxicity of G. pulchella were found. ...
Andean hylid frogs of the genus Hyla are reviewed. Eight groups of Hyla recognized in the Andes are defined; the species in two of these groups are treated in detail. The large H. armata, characterized by hypertrophied forelimbs and clumps of nuptial spines on the prepoUex and humerus in males, and a stream-adapted tadpole with a LTRF up to 15/17, is the sole recognized species in the H. armata...
In Utetheisa ornatrix (Lepidoptera, Arctiidae), the female mates preferentially with larger males. Having a larger father results in the eggs being more richly endowed with defensive pyrrolizidine alkaloid (which the female receives from the male with the sperm package, in quantity proportional to the male's body mass, and passes on to the eggs); having a larger father also results in the sons ...
