Abstract Thermal ecology and mate competition are both pervasive features of ecological adaptation. A surge recent work has uncovered the diversity ways in which temperature affects mating interactions sexual selection. However, potential for thermal biology reproductive to evolve together as organisms adapt their environment been underappreciated. Here, we develop a series hypotheses regarding (1) not only how system dynamics, but also dynamics can generate selection on traits; (2) consequences favour reciprocal co‐adaptation traits.

Global fertility rates continue to decline and sperm quality is a prime factor affecting male fertility. Both extreme cold heat have been demonstrated be associated with decreased quality, but no epidemiological studies considered human adaptation long-term temperature. Our aim was conduct multi-center retrospective cohort study investigate exposure-response relationship between temperature anomaly (TA) that deviate from climate patterns quality.

Chronic exposure to warm temperature causes low sperm abundance and quality in Drosophila melanogaster

Scientific Reports, Journal Year: 2023, Volume and Issue: 13(1)

Published: July 30, 2023

Abstract Temperature influences male fertility across organisms; however, how suboptimal temperatures affect adult spermatogenesis remains understudied. In a recent study on Drosophila melanogaster oogenesis, we observed drastic reduction in the of males exposed to warm temperature (29 °C). Here, show that become infertile at 29 °C because low sperm abundance and quality. The does not stem from reduced germline cell or spermatid numbers, as those numbers remain comparable between control 25 °C. Notably, cold 18 had similarly increased frequencies elongation individualization defects which, considering high measured °C, indicate has tolerance for defects. Interestingly, decreases abruptly with no evidence apoptosis they transition into seminal vesicle near end spermatogenesis, pointing elimination through an unknown mechanism. Finally, fertilize eggs less efficiently do support embryos past first stage embryogenesis, indicating poor quality is additional cause infertility

Vulnerability of amphibians to global warming

Published: Jan. 11, 2024

Amphibians are the most threatened vertebrates, yet their resilience to rising temperatures remains poorly understood. This is primarily because knowledge of thermal tolerance taxonomically and geographically biased, compromising global climate vulnerability assessments. Here, we employed a novel data imputation approach predict heat 60% amphibian species assessed daily temperature variation in refugia. We found 198 out 5203 currently exposed overheating events shaded terrestrial conditions. Despite accounting for plasticity, 4°C increase would create step-change impact severity, pushing 9.4% beyond physiological limits. In Southern Hemisphere, tropical encounter disproportionally more events, while Northern non-tropical susceptible. Our findings challenge evidence latitudinal gradients risk underscore importance considering climatic variability Notably, our conservative estimates assume access microenvironments, implying that warming’s impacts on amphibians may exceed projections. microclimate-explicit analyses also demonstrate how availability vegetation water bodies critical buffering during waves. Immediate action needed preserve manage these microhabitat features.

Short-term heat waves have long-term consequences for parents and offspring in stickleback

Behavioral Ecology, Journal Year: 2024, Volume and Issue: 35(4)

Published: April 27, 2024

Abstract Extreme temperature events, such as heat waves, can have lasting effects on the behavior, physiology, and reproductive success of organisms. Here, we examine impact short-term exposure to a simulated wave condition, parental care, in population threespine stickleback (Gasterosteus aculeatus), small fish with exclusive paternal currently experiencing regular waves. Males were either exposed (23 °C) for 5 d or held at an ideal (18 °C). Following this 5-d treatment, all males transferred 18 °C, where they completed full parenting cycle. Offspring raised °C. We found that while mass body condition unaffected wave, cortisol responses dampened across nesting cycle compared control males. In addition, had longer latency eggs hatch, lower hatching success, showed levels care behavior affecting swimming performance. Altogether, our results highlight long-term even events subsequent generations, providing insight into rapid environmental change.

Temperature Drives the Evolutionary Diversification of Male Harm in Drosophila melanogaster Flies

Ecology Letters, Journal Year: 2025, Volume and Issue: 28(3)

Published: March 1, 2025

Sexual selection often leads to sexual conflict via pre-copulatory (harassment) and/or copulatory (traumatic insemination) male harm females, impacting population growth, adaptation and evolutionary rescue. Male mechanisms are diverse taxonomically widespread, but we largely ignore what ecological factors modulate their diversification. Here, conducted experimental evolution under low- (20°C ± 4°C), moderate- (24°C 4°C) high-temperature (28°C regimes in Drosophila melanogaster, a species with harassment seminal fluid proteins (SFPs), show that temperature drives the divergent of conflict. At low-temperature regime, resulted reduced less plastic (i.e., harm) while at it was characterised by responses proteome driven differential expression SFPs. Our results suggest can be key understanding past diversification future (global warming) conflict, maintenance genetic variation traits.

Evolutionary responses may be crucial in allowing organisms to cope with prolonged effects of climate change. However, a clear understanding the dynamics adaptation warming environments is still lacking. Addressing how reproductive success evolves such deteriorating extremely relevant, as this trait constrained at temperatures below critical thermal limits. Experimental evolution under environment can elucidate potential populations respond rapid environmental changes. The few studies following framework lack analysis long-term response. We here focus on two Drosophila subobscura populations, from different European latitudes, temperatures. tested these ancestral (control) and after ∼50 generations evolution. found general adaptive response long term, since evolving showed increased performance that relative respective control populations. On other hand, no was observed environment. Coupled data previous generations, we highlight slow pace differences between distinct histories. These findings demonstrate need experiments fully reveal for adaptation. It also highlights scrutiny needed measure variation evolutionary within species.
