Rotifer samples were obtained from 29 localities in northern Guatemala and central-southern Belize during March 2000 and June 2001. A total of 119 species were identified. Ten selected taxa are illustrated and commented: Euchlanis semicarinata, Lepadella apsicora, L. cryphaea, Lecane curvicornis f. lofuana, L. whitfordi, Monommata maculata, Scaridium bostjani, Trichocerca elongata f. braziliens...

A marine-derived red alga, along with their active constituents, were actively screened for biocontrol potential against major insect pests. The current study explored the larvicidal activity of crude methanolic extracts alga Halymenia dilatata (Mx-Hd) Aedes aegypti (Linn.), and enzyme inhibition, repellent activity, non-target toxicity was species. Mx-Hd to exposed larvae dose-dependent, it si...

Mycorrhizal association is a common characteristic in a majority of land plants, and the survival and distribution of a species can depend on the distribution of suitable fungi in its habitat. Orchidaceae is one of the most species-rich angiosperm families, and all orchids are fully dependent on fungi for their seed germination and some also for subsequent growth and survival. Given this obliga...

Selective macroalgae comprising green algae (Ulva lactuca), brown (Padina gymnosphora, Sargassam wightii, Turbinaria ornate) and red (Gracilaria corticata, Halimeda macrolopa, Halymenia dilatata, Gracilaria crassa) were collected from Gulf of Mannar, India. Taxonomic molecular identification affirmed the identity microalgal species. Free fatty acids Fatty Acid Methyl Ester (FAME) synthesis by t...
