The events of meiosis I in a living insect spermatocyte beginning at metaphase I with bivalents at the spindle equator followed by anaphase, segregation of half-bivalents diakinesis and commencement o...

Time series of anaphase A and B of meiosis I in primary spermatocytes of the crane-fly Nephrotoma suturalis. Time-lapse polarization microscopy using a Nikon Microphot SA, equipped for liquid crysta...

This polarized photomicrograph shows the rows of suckers on the foreleg of a male Dytiscus marginalis, commonly known as the great diving beetle - the largest freshwater beetle in the UK. It has a lar...

Time series images showing the dynamics of kinetchore microtubules during meiosis I in primary spermatocytes of the crane-fly Nephrotoma suturalis that were experimentally flattened. Time-lapse polari...

Movie of anaphase A and B of meiosis I in primary spermatocytes of the crane-fly Nephrotoma suturalis. Time-lapse polarization microscopy using a Nikon Microphot SA, equipped for liquid crystal pola...
