Summary: Climate change can cause species to shift or expand their ranges. The wall brown butterfly has expanded in Sweden and adapted to northern daylength conditions, but lacks local adaptation to winter conditions. There is no clear difference in survival between individuals from different geographic locations during cold winters, and no evidence of local adaptation in metabolic rates or supercooling points. These findings highlight the need to consider the differences in traits associated with different seasons in adaptation and climate change-induced range expansions.

Summary: Developing molecules that mimic the properties of naturally occurring ice-binding proteins is challenging, but researchers have used phage display to identify a short peptide mimic containing only 14 amino acids. Key residues were identified through mutational analysis, and molecular dynamics simulations revealed a potential mechanism of action for ice binding. The peptide was also utilized for protein purification directly from cell lysate, demonstrating its biotechnological potential.

Summary: This study investigates the phenotypic and genomic changes of the Asian tiger mosquito, Aedes albopictus, in its native range and finds evidence of thermal adaptation and three evolutionary lineages. The study also identifies temperature-associated differentiation in certain genes, suggesting the role of directional selection. Furthermore, the study reveals that the mosquitoes store more energy in colder climates and that non-diapausing eggs from temperate populations have higher cold tolerance.

Summary: The study investigated the effectiveness of adding antifreeze protein (AFP) to a cryopreservative solution (PVS2) in reducing freezing injuries in Hosta capitata at different cold exposure times. Gene expression patterns showed that shoots treated with PVS2+AFP were more likely to resist cold stress, indicating higher cryopreservation efficiency compared to PVS2 alone. This suggests that AFP could be a potential cryoprotectant for preserving rare and commercially important plant germplasm.

Summary: This study investigated the expression patterns of heat shock protein 70 (Hsp70) in Pieris melete during summer and winter diapause. The results showed that the expression of PmHsc70 and PmHsp70b were upregulated during both diapause periods. Heat shock induced significant upregulation of all three genes during diapause. None of the genes responded to cold or heat stress in non-diapause pupae. Furthermore, it was found that 39 degrees C for 30 min was the most sensitive heat stress condition for PmHsc70 expression in summer diapause, and the same condition was effective for the expression of all three genes in winter diapause. These results suggest that PmHsp70s play an important role in responding to temperature stress during both summer and winter diapause.

Summary: Temperature is a crucial factor affecting the growth, survival, and reproduction of organisms. Thermal performance curves are useful for ectotherms, but endotherms have a more complex relationship with environmental temperature due to the decoupling of body temperature from external temperature. Improving understanding of endotherm thermoregulatory physiology through a comparative approach, measuring performance over a range of body temperatures, and building comprehensive mechanistic models are key directions for future research.

Summary: This study tested the assumptions that thermal performance can be predicted from constant temperatures in fluctuating temperature conditions using two latitudinally matched populations of Mytilus trossulus. The results showed that performance in fluctuating temperatures could not be accurately predicted from constant temperatures, with important interactions with the population of origin. The findings emphasize the need for caution when using TPCs generated under constant temperature conditions for predicting wild population responses to fluctuating conditions.

Summary: Ice-binding proteins (IBPs) have independently evolved in multiple taxonomic groups to improve survival at sub-zero temperatures. This study found that intertidal species were more likely to have IBPs compared to those primarily found in open ocean or freshwater habitats. A wide array of putative IBPs were identified in intertidal invertebrates, with high sequence similarity to fish and tick antifreeze proteins. Machine learning techniques predicted ice-binding activity in the majority of the newly identified putative IBPs. The potential evolutionary origin of one putative IBP from the hard-shelled mussel was also investigated.

Summary: Increasing temperatures have detrimental effects on endangered freshwater species, such as lake sturgeon. This study demonstrates that higher temperatures during development result in physiological consequences for lake sturgeon populations, including altered metabolic rate, thermal tolerance, transcriptional responses, growth, and mortality. The research also shows population-specific thresholds for transcriptional plasticity and mitochondrial function in response to elevated temperatures, highlighting the molecular impacts of increasing temperatures on divergent lake sturgeon populations.

Summary: Ongoing climate change has led to ocean acidification, resulting in rapidly increasing temperatures and a decline in seawater pH. This has caused species to redistribute towards higher and cooler latitudes, which are most impacted by ocean acidification. A recent study examined the combined effects of ocean acidification and freeze stress on mussel species survival and found that low pH conditions significantly decrease freeze tolerance.

Summary: This study observed the changes in population density of Indiana bats in different regions. The results showed that under the influence of climate change, the bat population shifted from the northern to the southern area. However, the outbreak of white-nose syndrome reversed the direction of population shift. These findings suggest that energy balance plays a crucial role in influencing bat population changes.
