De novo origins of multicellularity in response to predation SUMMARY: Chlamydomonas are common, single-celled green algae that are flagellated and can move around. They’re a strange cross between plants and protists. In this study, scientists subjected chlamydomonas to predation by paramecia (common freshwater ciliates) and observed that after about 750 generations, the chlamydomonas took on… Continue reading De novo origins of multicellularity in response to predation
Category: M&E 5: Changing Ecosystems (MS)
Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
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
Effects of Antibiotics on Plankton
Interspecies Interactions Reverse the Hazard of Antibiotics Exposure: A Plankton Community Study on Responses to Ciprofloxacin hydrochloride SUMMARY: Antibiotics that have made their way into aquatic ecosystems may have an effect on the food chains there. This study tested the effects of ciprofloxacin hydrochloride on 2 different types of algae (phytoplankton) and a species of… Continue reading Effects of Antibiotics on Plankton
