Among these is the transfer of the ejaculate composed mainly by sperm and accessory gland proteins (AGPs).

We studied the arbuscular mycorrhizal fungi (AMF) and dark septate fungi (DSF) in two lycopods and 23 ferns species collected from the tropical montane cloud forest in central Veracruz, Mexico. This is the first report of the mycorrhizal status for 17 species. Arbuscular mycorrhizal fungi were present in 11 species (44 %) which characterized by arbuscules and in a further 11 species were found...
Alsophila firma is a deciduous tree fern considered as an emblematic species of Mexican tropical montane cloud forest (TMCF). We studied spores diversity, structure and colonization by arbuscular mycorrhizal fungi (AMF) within the roots of the Alsophila firma in rainy and dry season. Eighteen species of the genera Acaulospora (5), Gigaspora (4), Glomus (4), Funneliformis (2), Sclerocystis (2) and...
