Buenos Aires city and surroundings is one of the largest 20 urban agglomerations in the World. It is crossed by the Reconquista River, a lowland course directly associated with millions of people. The present study deals with an assessment of microbial populations from surface water along the main course and its tributaries over a period of three years. These watercourses showed high levels of ...

– We examined the histology, histochemistry, and ultrastructure of Rathke’s glands in hatchlings of the three-toed box turtle, Terrapene carolina triunguis, and the desert box turtle, Terrapene ornata luteola. Both species possess one pair (axillary) of Rathke’s glands, which are similar anatomically and histochemically to one another. Each gland is composed of a single, highly vascularized sec...

The mantle is an important molluscan organ. It serves as a respiratory organ in most of the pulmonates; its walls have a dense vascular network. It is an outer jacket of the visceral mass and harbors the pulmonary chamber on its right side. Mantle is the specialized organ of the gastropods for it not only bears the glands that secrete the shell but also acts as buffer between the hard calcareou...

A new, biparental species of the genus Encarsia Förster (Hymenoptera: Aphelinidae), E. hera Lahey & Andreason, sp. nov. , is characterized based on morphological and molecular data. The parasitoid was reared from puparia its host, an undescribed grass-feeding aleyrodine Aleurocybotus Quaintance Baker (Hemiptera: Aleyrodidae) collected in Gainesville, Florida. same whitefly newly recorded Ch...

Context Cacti are endemic to North and South America, but numerous species have been spread all over the world after Europeans visited Americas. Their global has impacted various aspects of terrestrial ecosystems, including distributions succulenticolous myxomycetes. Aims In this study, we examine association myxomycetes (also known as plasmodial slime moulds or myxogastrids) with three introdu...
