Despite the diversity and functional importance of invertebrates, predicting their response to global warming remains challenging as it requires extensive measurements of physiological performance or rarely available high-resolution distribution data. Mechanistic models can help overcome these limitations by generalizing fundamental physiological processes. However, their predictions typically omit the effects of species interactions. Movement is a key process of species interactions underpinning animal performance in the real world. Here, we developed an empirically-grounded mechanistic model that incorporates allometric and thermodynamic constraints on movement and predator-prey interactions. We illustrate how it can be used to quantify the thermal performance of invertebrates under current and future climatic conditions. This trait-based approach (1) contributes to our understanding of the mechanisms underlying thermal fitness, (2) allows generalized predictions of thermal performance across invertebrate species worldwide and (3) can be used to inform species distribution models and thereby help infer species range limits under climate change.

“…The salmon study also showed a decrease in Tmax of approximately 10°C. Food limitation also decreased Topt and Tmax for population growth rate by about 6°C in mosquitoes (Huxley et al 2021). In some studies, however, a zooplankter Daphnia's survival at high temperature was higher when fed low phosphorus algae or poor food quality cyanobacteria (Starke et al 2021, Sarrazin andSperfeld 2022), suggesting that the effects of resource limitation may differ depending on the temporal scale of responses (Sarrazin and Sperfeld 2022).…”

Warming, the most prominent aspect of global environmental change, already affects most ecosystems on Earth. In recent years, biologists have increasingly integrated the effects of warming into their models by capturing how temperature shapes their physiology, ecology, behavior, evolutionary adaptation, and probability of extirpation/extinction. The more physiologically-grounded approaches to predicting ectotherms’ responses use thermal performance curves (TPCs) obtained by measuring species performance (e.g., growth rate) under different temperatures while other factors are held constant. These other factors are usually held at benign levels to ‘isolate’ the effects of temperature. Here we highlight that this practice may paint a misleading picture because TPCs are functions of other factors, including global change stressors. We review evidence that resource limitation, pH, oxygen and CO2 concentration, water availability, as well as parasites, all influence TPC shape and thermal traits such as optimum temperature for growth. Evidence from a wide variety of organisms – phytoplankton, protists, plants, insects, and fish – points towards such interactions increasing organisms’ susceptibility to high temperatures. Failing to account for these interactions is likely to lead to erroneous predictions of performance in nature and possibly an underestimation of the risks of warming. We discuss the general patterns and possible consequences of such interactions for ecological communities. But importantly, interactions with TPCs share common features that we can learn from. Incorporating these interactions into population and community models should lead to deeper insights and more accurate predictions of species’ performance in nature, now and in the future.

“…A geographical feature of these countries is a hot, humid climate and the presence of a fairly large number of small and small water bodies -habitats for the larvae of the malaria mosquito. The work [3] presents data that the temperature conditions of such reservoirs are very favorable for them. In turn, such spaces are often difficult to access.…”

The object of research is the procedure for processing digital images for remote registration of Gambusia sp., introduced into water bodies to combat malaria, which threatens not only the African region, but also other latitudes of the world. One of the most problematic areas of research is the elimination of the masking effect of a biological object under conditions of interference (for example, water turbidity) that make it difficult to recognize Gambusia sp. on digital images taken from aboard light drones. In the course of the study, approaches were used that allow dividing a digital image into segments and sub-segments, followed by determining the ratio of the colorimetric parameters of the RGB model of the bottom section. Dispersion and correlation analysis of mean values and mean square deviation values of the RGB model parameters were used. The standard deviation was considered as the degree of diversity of colorimetric parameters in the color of a biological object. The proposed procedure made it possible to reveal a moderate negative correlation between the predominance of green and yellow-orange-red phytopigments in the dynamics of the Margalef model of phytocenosis succession in the places of introduction and habitation of Gambusia sp. This is due to the fact that the shielding of phytocenosis areas by Gambusia sp. is reflected in the nature of the relationship of the colorimetric parameters of the RGB model of the bottom area, namely, they affect the correlation between the average values of the parameters G/(R+G+B) and R/G or between the mean value and the standard deviation of the parameter G/(R+G+B). This makes it possible to use Gambusia sp. in regions affected by malaria, a wide range of light drones with remote photofixation of relatively low quality. The implementation of these possibilities will require much less material costs and a small number of personnel than underwater video filming and other known methods for studying the ichthyofauna of small water bodies in conditions of interference. It is about the registration of the results of the introduction of Gambusia sp. in such water bodies to fight malaria.
