Reaction Network Modeling of Complex Ecological Interactions: Endosymbiosis and Multilevel Regulation

Tomas Veloz, Daniela Flores

Summary: Endosymbiosis is a type of symbiosis where a microscopic species inhabits the cell of a larger species, exchanging metabolic byproducts for mutual benefit. Modeling endosymbiosis requires a complex-systems and multilevel approach to understand how it promotes cell metabolism efficiency and protection from predators. A proposed model based on reaction networks represents different ecological species, resources, and conditions for interactions, with endosymbiotic mechanisms shown through sequences of reactions.

Kleptoplast distribution, photosynthetic efficiency and sequestration mechanisms in intertidal benthic foraminifera

Bruno Jesus, Thierry Jauffrais, Erik C. L. Trampe, Johannes W. Goessling, Charlotte Lekieffre, Anders Meibom, Michael Kuhl, Emmanuelle Geslin

Summary: The study investigated the relationship between feeding strategies, kleptoplast spatial distribution, and photosynthetic functionality in two shallow-water benthic foraminifera species. The results showed that the two species exhibited different feeding strategies, with one species having a higher autotrophic capacity despite both feeding on benthic diatoms. This may represent different stages in the evolutionary process of establishing a permanent symbiotic relationship or reflect different trophic strategies.

Application of LCA and LCC in the early stages of wastewater treatment design: A multiple case study of brine effluents

Steve Harris, George Tsalidis, Joan Berzosa Corbera, Jose Jorge Espi Gallart, Fredrik Tegstedt

Summary: This paper discusses the use of Life Cycle Assessment (LCA) and Life Cycle Costing (LCC) in developing technology solutions for treating brine wastewater and recovering by-products. Four industrial case studies are assessed to identify critical hotspots and design improvements, with a focus on reducing chemical and energy consumption, maximizing by-product recovery, and utilizing renewable energy. The analysis shows that the impact and cost of treatment depend significantly on the composition of the wastewater, and that the recovery of compounds and deionised water can potentially offset these costs.

Healthy Long-Lived Human Beings-Working on Life Stages to Break the Limitation of Human Lifespans

Weikuan Gu

Summary: This paper proposes a hypothesis that by elongating different life stages and adopting specific strategies, the human lifespan could become extremely long and healthy. The current focus on aging stage in lifespan extension research overlooks the importance of other stages. Clarifying the boundaries and transitions of life stages is crucial for developing life-stage-specific biomedical interventions and pharmacological treatments. The hypothesis can be tested through modified longevity studies using various technologies such as castration and ovariectomy, taking into account sex differences and the sequential order of life stages.

Contrasting response of Gracilaria chilensis (Gracilariales, Rhodophyta) life cycle stages to epiphyte infection

Sara Usandizaga, Jessica Beltran, Sylvain Faugeron, Carolina Camus

Summary: This study investigated the susceptibility of the red seaweed Gracilaria chilensis, extensively cultivated in Chile for agar extraction, to the red epiphyte Acrochaetium sp. and the brown epiphyte Ectocarpus sp. The results showed that tetrasporophytes from both natural and cultivated populations had similar responses to both epiphytes. Additionally, individuals infected with Acrochaetium had a higher defense capacity, while infection with the brown alga did not induce a significant release of phenolic compounds. Overall, the cultivation of females may have long-term benefits for farms by reducing biomass losses under stressful conditions and epiphyte invasions.

Similarities in biomass and energy reserves among coral colonies from contrasting reef environments

Elise F. Keister, Shelby E. Gantt, Hannah G. Reich, Kira E. Turnham, Timothy G. Bateman, Todd C. LaJeunesse, Mark E. Warner, Dustin W. Kemp

Summary: Coral reefs worldwide are declining, but some populations in Palau, Micronesia are better adapted to survive in warmer and more acidic oceans. These coral populations can resist and recover from thermal stress better than their offshore counterparts. The difference in tissue biomass and energy reserves between the nearshore and offshore colonies may be explained by the increased metabolic demand of the warmer and more acidic nearshore environment. Despite the differences in symbiont species and prey availability, the lipid compositions of colonies from both habitats were similar. The regulation of colony biomass and energy reserves may be influenced by various factors, but they converge to a similar homeostatic set point under different environmental conditions.
