Summary: Temperature variation at a small-scale can have significant effects on the development and emergence synchrony of butterflies. However, the correlation between different life stages' development times can lead to reduced temporal differences in the overall development. Importantly, the fastest developing sites were not always the warmest, highlighting the unintuitive effects of temperature on population-level consequences.

Summary: Fine-scale climate information is crucial to understand species-climate relationships, especially in mountain areas. The cloud-corrected model presented in this study improves air temperature predictions by incorporating solar radiation and cloud cover data. This method provides a promising opportunity to enhance the understanding of species-climate relationships in regions sensitive to climate change.

Summary: Understanding the impact of multifactorial fluctuating environments on species and communities is a major challenge. This study investigated the influence of spatial correlation between warming and sediment deposition on the biomass and photosynthetic activity of rocky intertidal biofilm using field experiments and simulations. The results showed that the spatial correlation between the two climate variables determined the nonlinear response of biofilm biomass, but not photosynthetic activity, to fluctuating levels of warming and sediment deposition. Negative spatial correlation buffered against extreme levels of warming and sediment deposition.

Summary: This study investigates the impacts of climate change and microclimate on the future energy performance of buildings using high spatiotemporal resolution building energy models. The results show that microclimate can significantly affect cooling and heating demands, especially during extreme weather conditions. The findings also highlight the increasing cooling demand and overheating hours in the future, emphasizing the need for better adaptation to climate change in urban areas.

Summary: This study analyzed the timing of pesticide treatments in field vegetable crops, identified the phenology of different pests, and found that farmers followed the principles of Integrated Pest Management (IPM) in chemical control. The results provide a long-term baseline for future surveys on changes in pesticide use and associated risks in the studied crops.

Summary: This study assesses the phenotypic variation of main culm panicle node number (MCPNN), maximum node production rate (MNPR), and degree-days to heading (DDTH) in a diverse rice population. The researchers identified SNP markers associated with these traits and potential candidate genes. Understanding the genetic basis of these primary traits could lead to more efficient breeding methods and increased grain yield in rice.

Summary: In this work, new measures of cumulative residual Fisher information and relative cumulative residual Fisher information were proposed, and their properties were established. These measures were expressed based on hazard functions and Jensen inequality, with discussions on connections between different information measures using a new version of de Bruijn's identity for survival functions.

Summary: This paper considers the vertex-degree function index Hf(G) when the function f(x) belongs to four classes of functions based on strict convexity vs strict concavity and strict increasing vs strict decreasing. It determines the quasi-unicyclic graphs that are extremal with respect to the vertex-degree function index for these classes of functions, given a certain order or a certain order and a fixed number of pendant vertices. These conditions are met by several topological indices of graphs.

Summary: Seasons impose different selection pressures on organisms, leading to varying adaptive strategies. This study investigates the resolution of seasonal conflicts in two closely related butterfly species through field experiments, laboratory work, and citizen science data analyses. The results reveal differences in fitness and population dynamics between Pieris rapae and P. napi across seasons, driven by physiological and behavioral traits. P. rapae maximizes gains during growth seasons but suffers from higher winter mortality, while P. napi minimizes harm during adverse seasons.

Summary: In ecology, it is important to capture temperature variation at relevant scales. Spectral analysis of temperature time series and sinc interpolation can be used to reconstruct continuous thermal regimes from regular, discrete measurements. The Nyquist-Shannon sampling theorem states that continuous complex waveforms can be perfectly sinc-interpolated from discrete, regular samples if sampling intervals are sufficiently short. These concepts have potential applications in ecology for predicting insect development times and producing accurate continuous thermal regimes from sparse temperature measurements.
