Summary: Reproductive isolation can occur due to differences in mate preference associated with body size, which can play a role in divergence between groups. The goal of the study was to examine differences in mate preference between two ecotypes of Threespine Stickleback males, with one ecotype providing parental care. Results showed that males investing in parental care preferred larger females, while those not providing care did not exhibit a preference for larger females.

Summary: This study examined the effects of population density and body mass on mating strategies and reproductive success in Brandt's voles. The results showed that individuals with more mating partners had increased reproductive success, especially in high-density environments. The findings highlight the importance of understanding individual reproductive strategies and their implications for population growth.

Summary: Quantifying the effects of individual attributes and population demographic characteristics on inter- and intrasexual interactions and adult reproductive success, as well as the spatial and temporal contexts in which they occur, is crucial for effective species management. Through multi-year individual-based analyses, using genetically determined parentage, factors associated with the reproductive success of male and female lake sturgeon in Black Lake, Michigan were examined. Results showed that factors differed between sexes and varied within and among spawning groups, and that certain factors contributed to higher interindividual variance in reproductive success and influenced population levels of recruitment, genetic structure, and effective population size.

Summary: Genetic based mosquito control methods have the potential to effectively suppress or replace vector populations without causing environmental damage or public health risks. The quality of sterilized male mosquitoes is crucial for the success of the Sterile Insect Technique (SIT) control programs. Transportation, especially for long durations, can negatively impact the performance of sterilized males and needs to be carefully managed.

Summary: Male-biased operational sex ratios increase male-male competition and select for increased pre- and postcopulatory male success. In this study, we found that males evolved under male-biased sex ratios had higher mating success and courtship frequency compared to females evolved under female-biased sex ratios. Female mating status also influenced male mating success.

Summary: Understanding the factors that determine differential reproductive success is crucial in evolutionary biology. Social relationships, particularly in males, play a significant role in fitness and reproductive opportunities. A study on unrelated male bottlenose dolphins in Shark Bay, Australia revealed that well-integrated males with more homogeneous social bonds achieved higher paternities. This highlights the adaptive value of social bonds in polyadic cooperation among unrelated males.

Summary: The study identified a takeout gene, named Bdtakeout2, highly expressed in the male accessory glands of Bactrocera dorsalis, playing a critical role in male mating behavior and fertility. Treatment with exogenous hormones and photoperiod exposure influenced the expression of Bdtakeout2, affecting male mating success and female fertility.

Summary: Incorporating microsatellite techniques to determine parentage in wild animal mating system studies is powerful. The study found that non-territorial males behave differently from territorial males, and in simple habitats, courtship behavior by territorial males is more likely to predict paternity, emphasizing the importance of considering different social tactics and environmental conditions when testing the accuracy of behaviorally based estimates of breeding relationships.

Summary: This study investigated the courtship and mating behavior of the neem bug, Halys dentatus, and found population-level lateralization in males approaching females. Furthermore, the male mating success was affected by lateralization, where right-biased males achieved higher mating success rates. The study highlights the importance of lateralized traits in determining male mating success in insects.

Summary: The mating pattern of the emerald glass frog, Espadarana prosoblepon, is random with respect to body size, and there is no evidence for a correlation between male size and fertilization success. Therefore, body size does not appear to play a significant role in influencing mating patterns in anurans.

Summary: The study found that in biparental care in ravens, mothers are more likely to invest and care for offspring, while paternal care is selective and tends to favor heavier sons. Brood size affects chicks' begging behavior, but decreases their chances of being fed.

Summary: The study suggests that pursuing extrapair copulations may be a natural instinct in birds, and the interaction between males and females for EPCs may lead to larger brains. However, larger brains may also restrict the EPC level for both sexes across bird species, as indicated by the negative association between relative brain size and EPP rates.

Summary: Social polygyny benefits males by increasing offspring numbers, but is detrimental for females due to resource sharing. In bird species with bi-parental care, like Eurasian kestrels, polygyny occurs more frequently during years with abundant prey, impacting secondary females' reproductive success negatively. Males space out their nests to deceive secondary partners, leading to poor reproductive outcomes, highlighting deceptive behavior during courtship as a key factor in maladaptive mate choice.

Summary: Cryptic male mate choice refers to the differential allocation of resources by males to females during or after copulation. In the fruit fly Drosophila melanogaster, males mate longer and allocate more resources to larger females compared to smaller females. However, it is unclear if this increased investment in larger females has any impact on the males' subsequent matings.

Summary: The study focuses on the quantification of capillary penetration extent in the skin and its implications in biological studies. The findings provide evidence that loose skin confers a defensive advantage in combat and support the idea that the cooccurrence of loose skin and underwater calling in frogs is related to respiratory surface area. The study highlights the importance of understanding the usefulness of this ratio in skin studies.
