Protozoa and plant growth: the microbial loop in soil revisited

Protozoa and plant growth: the microbial loop in soil revisited (NOT OPEN ACCESS) SUMMARY: This is an in-depth review on the rhizosphere and the interactions between protozoa, nematodes, and plant roots. LESSON COMMENTS: This can be read like a textbook for students. Alternatively, teachers can assign relevant sections. The rhizosphere can be grown and observed… Continue reading Protozoa and plant growth: the microbial loop in soil revisited

Coal Formation Not Correlated with Fungal Evolution

Delayed fungal evolution did not cause the Paleozoic peak in coal production SUMMARY: This article provides evidence to refute the theory that most of our coal was formed during a period of time (Carboniferous-Permian age, about 299 million years ago) when fungus had not evolved enzymes to digest lignin. Plant material was thought to have… Continue reading Coal Formation Not Correlated with Fungal Evolution

Beaming Naphthalene Part 1

Infrared Study of UV/EUV Irradiation of Naphthalene in H2O+NH3 Ice SUMMARY: This study beamed naphthalene in a mixture of water and ammonia ice with different energy levels of UV light. Results showed that naphthalene breaks down and the pieces react into various small carbon-based compounds. Since conditions of this experiment try to replicate those found… Continue reading Beaming Naphthalene Part 1

Taking Methane Production Into Account

Climate-driven shifts in sediment chemistry enhance methane production in northern lakes SUMMARY: Different types of plant material decay and produce different amounts of methane. Methane is a more potent greenhouse gas compared to CO2 and decomposes into CO2 in the atmosphere. This study compared methane production of various types of plants. Plant material was collected… Continue reading Taking Methane Production Into Account
