Heteroptera is a worldwide distributed group of insects inhabiting both terrestrial and aquatic habitats and has an important ecological role. A survey of aquatic and semiaquatic Heteroptera from Cuba is provided based on literature reports and field collections. General data on species geographical distribution are given, along with altitude and collection season. Representatives of 86 species...

The entomopathogenic fungus Beauveria bassiana was re-isolated from surface sterilized pieces of the cocoa pod outer section and peduncle, two and three months after flowers of greenhouse cocoa plants were hand-pollinated and sprayed with a 1x107 mL-1 suspension of B. bassiana conidia. The colonization frequency of B. bassiana on cocoa pods was 0.8% and 1.3% two and three months post-spraying o...

botrytis cinerea is an important pathogen that causes diseases in ornamental crops. in presentresearch several greenhouses of roses located in central region of iran were surveyed toidentify the botrytis cinerea. a total of 80 isolates were collected from rose greenhouses incentral region of iran. morphological identification was based on characters such asconidiophore and conidial length. acco...

Shallow-water rhodolith beds are rare in the Mediterranean Sea and generally poorly known. The Punta de la Mona bed extends for 16,000 square meters shallow oligotrophic waters at southern coast of Spain, off Almuñecar Alborán Sea. We present a detailed analysis structure (rhodolith cover density, size shape, sediment granulometry) morphospecies composition along depth gradient. A stratified sa...

Problematic microfossils dominate the palaeontological record between the Great Oxidation Event 2.4 billion years ago (Ga) and the last Palaeoproterozoic iron formations, deposited 500-600 million years later. These fossils are often associated with iron-rich sedimentary rocks, but their affinities, metabolism, and, hence, their contributions to Earth surface oxidation and Fe deposition remain ...

Abstract The identification of Stasimopus Simon, 1892 species as well mygalomorph has been a long-standing challenge. This is due to their conservative morphologies the lack quantifiable characters. Ocular patterns have historically used aid in identification, but largely vague and subjective. study was first test for phylogenetic signal this character validate its use description viability it ...
