“…Thermal tolerance physiology can be influenced by the quality of trophic resources as reported by Colinet et al (2013), who found that sugar-enriched diets increased chill coma recovery ability in the fruit fly Drosophila melanogaster. In other studies, low diet quality had no effect on the critical thermal maximum of the chrysomelid Cephaloleia belti (Garcia-Robledo et al, 2018), whereas the feeding status (fed versus starved insects) of the fly Ceratitis capitata (Nyamukondiwa and Terblanche, 2009) affected their thermal tolerance, and starvation lowered the supercooling point -and increased cold tolerance -in the beetle Alphitobius diaperinus (Salin et al, 2000). The overall quality of the environment can contribute to temperature tolerance in insects, either directly, or by eliminating some level of multi-stress exposure occurring when factors such as starvation or dehydration coincide.…”

This study aims to design a smart closed reactor of vermicomposting to convert sewage sludge and any organic waste to high-quality vermicompost. In this reactor design, all aspects of growth and reproduction of Eisenia Fetida worms, such as aeration, temperature, light, and moisture, were considered. We analyzed the physicochemical, bacterial, and microstructural of produced vermicompost and growth rate of worms in a substrate of 70% sewage sludge, 20% cow manure, and 10% sugarcane bagasse in a container and the smart reactor. The results show that vermicomposting in the smart reactor took 50% less time and 30% more worm growth rate to produce the same quality as in a container. After vermicomposting in the reactor, the parameters of pH, fecal coliform, phosphorus, organic matter, and C/N decreased whereas the parameters of carbon, nitrogen, nitrate, ammonia nitrate, and EC increased, slightly. Although, the EC amount of the reactor production is more than the container one, the amount of moisture, phosphorus, and organic matter of the vermicompost in the container is more than the reactor one.Based on the odor absorption and leachate elimination of this reactor, we recommend that it be utilized for vermicompost production, including out of smelly organic wastes such as sewage sludge, even in any public zone and personal houses.

2020. The affordable laboratory of climate change: devices to estimate ectotherm vital rates under projected global warming. Ecosphere 11(5):e03083.Abstract. Determining organisms' responses to novel temperatures is relevant from ecological, evolutionary, and conservation perspectives. Here, we have validated designs and included biological examples for three affordable devices to estimate thermal responses of ectotherms: (1) a water bath that can be programmed to increase temperatures to estimate an organismal critical thermal maximum (CT max ), (2) a miniature portable refrigerator to estimate an organism's critical thermal minimum (CT min ), and (3) inexpensive growth chambers that maintain constant temperatures or simulate dynamic environmental temperature patterns. We tested the reliability of the CT max device at temperature increase rates of 1°and 2°C/min. Observed temperatures deviated 0.01°C and 0.02°C from target temperatures, respectively. The CT min device easily attained target temperatures via manipulation of the input voltage. The maximum deviation from target temperatures in environmental chambers programmed to maintain constant temperatures between 10°C and 30°C was 0.8°C. Environmental chambers programmed to simulate temperature profiles of tropical rain and montane forests deviated from target temperatures by a maximum of À0.5°C to 0.9°C. Examples of applications show that (1) tropical insects at high elevations are less tolerant to high temperatures than insects in lowland forests, (2) nocturnal ants display lower CT max and CT min than diurnal ant species, and (3) experiments in growth chambers show high mortality of high-elevation insect species when exposed to temperatures that typify lowland forests, and high mortality of lowland insect species when exposed to temperatures that typify high elevations. The devices described in this study can be mass-produced inexpensively and are currently being used in laboratories in the United States, Mexico, and Costa Rica. The main goal of this project is to encourage the construction of affordable devices and the use of standardized methodologies to create a global network of researchers studying thermal responses in diverse taxa and geographic locations.
