Pteriid oysters (Pinctada maxima, Pinctada margaritifera, Pinctada albina, Pteria penguin), rock oysters (Saccostrea glomerata, Saccostrea cuccullata, Saccostrea echinata) and representatives of other taxa (Malleidae, Isognomonidae, Pinnidae, Mytilidae, Spondylidae, Arcidae) from the wild, and 4670 hatchery-reared P. maxima, from northern and Western Australia, were examined for parasites and d...

This study tested the effects of low salinity on phenoloxidase activity in Sydney rock oysters (Saccostrea glomerata). Phenoloxidase is a key component of the immune system in S. glomerata. Previously, we have shown that decreased phenoloxidase activity is associated with susceptibility to fatal QX disease. In the current study, laboratory-based experiments were used to identify factors that co...

Aphids feed on plant phloem sap, rich in sugars but poor in essential amino acids. However, sugars cause osmotic regulation problems for aphids, which they overcome by hydrolysing the sugars in their gut and polymerising the hydrolysis products into oligosaccharides, excreted with honeydew. Aphids harbour primary bacterial endosymbionts, which supply them with essential amino acids necessary fo...

The antioxidant effect of aqueous extract of the bark of FB has been evaluated in hypercholesterolaemic rabbits. The water extracts of the bark of Ficus benghalensis at a dose of 50 mg/kg body weight per day in addition to cholesterol suspended in oil. There results show that the water extract of the bark of Ficus benghalensis has significant antioxidant effect, in addition to hypolipidaemic ef...

Ficus religiosa (Bo tree) is the most popular member of the genus Ficus, commonly named as Peepal. Various parts of the plant, like bark, fruit, leaves and seeds are widely used in indigenous system of medicine. F. religiosa showed a wide spectrum of pharmacological activities like, anticonvulsant, anthelmintic, anti-amnesic, anti-anxiety, anti-asthmatic, antibacterial, antioxidant, anti-inflam...

Mutualisms are interspecific interactions in which both players benefit. Explaining their maintenance is problematic, because cheaters should outcompete cooperative conspecifics, leading to mutualism instability. Monoecious figs (Ficus) are pollinated by host-specific wasps (Agaonidae), whose larvae gall ovules in their "fruits" (syconia). Female pollinating wasps oviposit directly into Ficus o...

The majority of species in the mulberry family (Moraceae) are figs (Ficus), marked by a specialized inflorescence (syconium) and an obligate mutualism with pollinating fig wasps. Because of the unique morphology of the syconium, it has been difficult to investigate the evolutionary position of the fig. We sequenced the chloroplast gene ndhF to examine relationships in Moraceae and to elucidate ...

Hemiepiphytic Ficus species (Hs) possess traits of more conservative water use compared with non-hemiepiphytic Ficus species (NHs) even during their terrestrial growth phase, which may result in significant differences in photosynthetic light use between these two growth forms. Stem hydraulic conductivity, leaf gas exchange and chlorophyll fluorescence were compared in adult trees of five Hs an...

Occurrence of inter-species hybrids in natural populations might be evidence of gene flow between species. In the present study we found evidence of gene flow between two sympatric, genetically related scale insect species--the citrus mealybug Planococcus citri (Risso) and the vine mealybug Planococcus ficus (Signoret). These species can be distinguished by morphological, behavioral, and molecu...

The Mikania glomerata Spreng is a specie found in Europe, Africa, North and South America commonly known as “guaco” “guaco climber”. Many scientific studies confirm the bactericidal, anti-ophidic, antifungal, anti-inflammatory, antimalarial, bronchodilator pharmacological activities. These aim to contribute new research, report phytotherapy aspects describe therapeutical properties of glomerata...
