Temperature can influence mosquito-borne diseases like dengue. These effects are expected to vary geographically and over time in both magnitude direction may interact with other environmental variables, making it difficult anticipate changes response climate change. Here, we investigate global variation temperature–dengue relationship by analyzing published correlations between temperature dengue matching them remotely sensed climatic socioeconomic data. We found that the correlation was most positive at intermediate (near 24°C) temperatures, as predicted from an independent mechanistic model. Positive associations were strongest when population density high decreased infection burden rainfall mean variation, suggesting alternative limiting factors on transmission. Our results show while context-dependent they also predictable thermal biology of transmission its social mediators.

Climate change will continue to increase mean global temperatures with daily minima increasing more than maxima temperatures. Altered rainfall patterns due climate also disrupt water availability for terrestrial organisms already facing climatic warming. To explore how may adjust changes in multiple, concurrent climate‐related environmental conditions, we manipulated day and night as well during gestation female common lizards Zootoca vivipara , a cold wet adapted species notably populations located on the warm margin. We jointly temperature (hot or cold) independently daytime nighttime (± ad libitum access water) throughout pregnancy quantified effects maternal traits (morphology, physiology phenology) reproductive output. Overall, found that higher decreased length increased energetic demands. Higher day, coupled restrictions, dehydration restrictions affected ability allocate resources but had no impact While high were beneficial current output success, opposite effect. Our results suggest can dramatically burden pregnant mothers constrained by heavy resource investment. This could provide mechanistic explanation long‐term declines of warm‐margin this species.

Studies examining the underlying causes of distributions species and their future trajectories under climate change have benefitted from accumulation measurements thermal tolerance across tree life. However, gaps in global coverage heat-tolerance data for ectotherms persist on four critical fronts. First, most large-scale analyses treat heat as a fixed trait despite that population-level variation can equal or exceed cross-species variation. Second, terrestrial non-arthropod invertebrates aquatic other than bony fish been poorly sampled, particularly boreal tropical regions, Indian Ocean mesopelagic-deep ocean. Third, study impacts has often neglected interaction environmental temperatures with water availability. And fourth, mechanisms driving dependence oxygen supply-demand remain largely unknown. We contend filling those knowledge requires novel strategies ecophysiological sampling range understudied populations occupy length climatic gradients globally. Such developments are essential comprehensively predicting responses to biomes.

Abstract Desert animals must manage the physiological stress caused by heat and desiccation; evaporative loss mitigates overheating but exacerbates water stress. Small endothermic flying insects may be particularly vulnerable to as a result of high surface area volume ratios, we lack quantitative understanding relative magnitude these abiotic stressors in desert invertebrates, despite their ecological importance. During hottest driest weeks year, many thousands males Sonoran digger bee ( Centris caesalpiniae ) flew near‐continuously at elevated thorax temperatures for hours mating aggregation sites, while fighting other digging females. To determine whether incapacitating or limited activity period male C. , assessed wet dry body mass content through period, flight durations using mark–recapture methods, crop sugar content, microclimate selection, balance during flight, critical maximum temperature. Body masses sizes declined morning. scaled isometrically with total mass. Crop did not vary throughout day size. Maximum temperature was 51°C large‐morph males, similar those measured bees, well above reached field, suggesting that avoidance does limit this bee. The bees averaged 50%, low end bees. Measures net rate indicated approached lethal limits within 4 h, duration range daily activity, desiccation tolerance activity. Remarkably, were observed forage floral sources yet they returned over multiple days, have mechanism rehydrate when aggregation. Read free Plain Language Summary article on Journal blog.

Shifts in species' interactions are implicated as an important proximate cause underpinning climate-change-related extinction. However, there is little empirical evidence on the pathways through which climate conditions, such ambient temperature, impact community dynamics. The timing of activities a widespread behavioural adaptation to environmental variability, and temporal partitioning key mechanism that facilitates coexistence, especially within large carnivore communities. We investigated temperature impacts dynamics its influence diel activity of, amongst, four sympatric species African carnivores: lions (
