Summary: This research examines the impact of social mobility on reproductive decisions and life history strategies. Through multiple studies, it is found that high social mobility is associated with delayed reproduction due to individuals' positive future expectations and focus on long-term goals, leading to a slow life history strategy.

Summary: Most plant species have either annual or perennial life cycles, but there are facultative annual species that can be either annual or perennial depending on their environment. While facultative annual species are rare in terrestrial plants, they are more common in marine angiosperms, particularly seagrasses. Six of the 63 seagrass species are facultative annual, producing significantly more seeds than their perennial counterparts. These facultative annual species can transition to an annual life cycle when exposed to specific environmental factors such as desiccation, anoxia, shading, or heat stress. A large-scale coastal protection experiment demonstrated that the facultative annual seagrass population could shift to a perennial life cycle within 5 years depending on the environmental conditions.

Summary: Studying the genetic basis of age at maturity in four species of Pacific salmonids revealed heterogeneous genetic architecture of this key life-history trait across the species. While significant associations were found between six6 and age at maturity in two species, particularly strong in Steelhead, no significant associations were detected between vgll3 and age at maturity in any of the species.

Summary: Maternal resource availability and metabolism have a limiting effect on reproductive output. Allomaternal care and domestication increase maternal energy, leading to an increase in reproductive output. Different forms of external energetic supplementation have varying effects on fertility increase.

Summary: Research shows that the assumption of isometry in the management models of fisheries leads to an overestimation of the replenishment potential of exploited fish stocks, risking systematic overharvesting. By considering hyperallometric reproduction, management strategies could be optimized to increase yields and maintain target replenishment levels.

Summary: The study found that while eelgrass populations in North Carolina produced smaller seeds at greater densities compared to more northern North American populations, there was no significant difference in seed viability across seed sizes. However, larger seeds had higher absolute carbohydrate and protein content, suggesting that energy resources in larger seeds may lead to better seed germination success. Additionally, there was site-based variation in seed characteristics despite similar temperature environments, indicating that local-scale factors may influence seed size and composition in Zostera marina.

Summary: Ladybird beetles are important predators in agriculture, with Eriopis connexa showing potential advantages for pest management. Research on the species' polyandry and paternity is limited, but findings suggest that progeny production for this beetle is relatively straightforward.

Summary: Through long-term data analysis on a threatened songbird, we find that early-life telomere length can predict the senescence of reproductive traits, such as clutch size and hatching success. However, early-life telomere length does not predict lifespan or lifetime reproductive success. These findings provide insights on the role of telomeres in reproductive senescence and individual fitness, and suggest telomere length as a predictor for future life history in threatened species.

Summary: The study shows that different stocks of Argentinean southern king crab are affected by fisheries in different phases, including sperm limitation and recruitment overfishing. The Beagle Channel stock is experiencing recruitment overfishing, while the San Jorge Gulf stock shows sperm limitation. The stock off the Atlantic coast of Isla Grande de Tierra del Fuego exhibited healthy population parameters before exploratory fishing.

Summary: The ability tovisualise the internal anatomical structures of fish has contributed greatly to fishbiology by providing important information on their reproductive status and body condition. Traditional methods of acquiring such information have involved euthanasia and dissection, which are known to cause stress. However, the development of waterproof, contactless, and portable equipment has allowed for non-invasive ultrasonographic examinations, even in free-swimming individuals. This study validated the use of this equipment on manta and devil ray specimens and demonstrated its reliability in determining the sexual maturity and gestational status of free-swimming reef manta rays.

Summary: The study reveals that the reproductive characteristics of co-occurring freespine flathead and mud flathead in the continental shelf waters of eastern Australia are influenced by fisheries, with differences in sex ratios and reproductive ecology. This has important implications for fisheries management and contributes to the data-poor international knowledge base of platycephalid biology.

Summary: The study revealed that male and female Petrolisthes japonicus exhibit different sexual size dimorphisms during the breeding season and nonbreeding season, with females investing more energy in pleon growth and males investing more energy in cheliped growth during the breeding season. In the nonbreeding season, both males and females conserve energy by reducing the size of their pleons and chelipeds.

Summary: The use of species' traits in macroecological analyses has become increasingly popular in the past decade, with mammals being among the most studied taxa due to the availability of abundant trait information. The creation of COMBINE, a database containing 54 traits for over 6,000 mammal species, aims to maximize trait coverage while maintaining data quality, providing valuable resources for ecological and conservation analyses.

Summary: Research shows that ctenophores, specifically Mnemiopsis leidyi, do not have separate phases of early and adult reproduction. They start reproducing at a small body size and continue spawning under suitable environmental conditions. The constraints on reproductive capacity are similar in both small and large animals. These findings have significant implications for understanding resource partitioning and managing the species in its invaded range.

Summary: This study provides an evolutionary perspective on the discrepancy between reproductive intention and subsequent behavior in the context of China's two-child policy. It found that maternal fertility intention did not always align with realized childbearing, partly due to lack of support or conflicts within the family, as well as the influence of husband's and firstborn's emotional support.

Summary: The study suggests that there is a need for improved algorithms to forecast future births based on women's fertility intentions, emphasizing the importance of adjusting all fertility intentions in birth forecasting. The results predict a baby boom in 2016-2018 after the universal two-child policy, with annual births increasing by up to 13%, which is consistent with official reports.
