Summary: This study analyzed the gametogenesis and reproduction characteristics of S. elegans from the Sao Francisco River in Tres Marias, Minas Gerais. The results showed that the first gonadal maturation occurred at a total length of approximately 10.5 cm in males and 15.0 cm in females. Reproduction mainly took place from September to April, during which there were high water temperature values. Females had a higher frequency at the mature and spawned stages, as well as a higher gonadosomatic index (GSI). In contrast, the reproductive peak for males was from November to February. The long spawning period and histological features of the spawned ovaries suggest that the spawning of S. elegans is of the partial type.

Summary: Parents facing predators must balance their own safety with caring for their offspring. Factors such as adult survival probabilities and species size influence their willingness to take risks and return to care for their young. Ultimately, the level of risk posed by a predator and the likelihood of future reproduction play a role in determining parental behavior across different species.

Summary: The possibility of extending human life span through nutritional, genetic, or pharmacological interventions has raised the prospect of transforming medicine to slow, stop, or even reverse age-related diseases. Plant and animal models, such as Hydra spp., which exhibit negligible senescence, and long-lived species like the bowhead whale, Greenland shark, and giant tortoises, suggest that humans may have the potential for significantly longer healthy life spans. This article discusses the biological restraints on human life extension based on evolutionary aging and current genetic and molecular insights into age-related functional decline and disease risk.

Summary: Organisms balance limited resources for reproduction and somatic maintenance to maximize fitness. In the blowfly Lucilia sericata, resource allocation to reproduction declines with age, shown by decreases in lipid content in the ovary, number and size of eggs per batch. Changes in individual eggs' lipid and protein content with age were relatively slight. This study highlights the importance of considering both biochemical measures and observable reproductive effort in evaluating resource allocation strategies.

Summary: This study investigates the impact of variables such as climate, landscape composition, management practices, and wild bee pollination on commercial apple production. The results show that apple yields are mainly influenced by management practices, not the contribution of managed honey bees. Wild bee diversity is negatively correlated with honey bee dominance but promotes apple quality. Thus, harnessing wild bee diversity can be a nature-based solution and a substitute for an exclusive reliance on honey bees in apple production.

Summary: We report the discovery of a spider-hunting wasp species, Trypoxylon petiolatum, in three localities in Catalonia, Spain. This species, native to eastern Asia, has not been previously reported in Europe. We provide a detailed description of the species and information on its nest architecture, cocoon shape, spiders captured for nest provisioning, and mortality rates, including parasitism by a native cleptoparasitic fly and a native parasitoid wasp.

Summary: This study explored the relationship between pollinator traits and pollination effectiveness (PE) by using single-visit pollen deposition to apple flowers. The results showed that PE was positively correlated with flower handling behavior (top-working visitors were more effective) and was also correlated with body size and visit duration, but not with hairiness. There were significant differences in PE among different pollinator species, with solitary bees being more effective than social bees, dipterans, and beetles. Effective pollinators were mostly top-workers, but did not necessarily share similar traits.

Summary: This study simulated the long-term exposure of bees to pesticides in agricultural ecosystems and evaluated the effects of insecticides and fungicides on bees. The results showed that the insecticide significantly reduced bee survival and neurological enzyme activity, while the fungicide caused a temporary decrease in syrup consumption and potential molecular alterations. Co-exposure did not increase toxicity. Acetylcholinesterase was identified as an effective biomarker for early detection of effects.

Summary: Pollen and nectar samples from melon flowers were analyzed for pesticide residues, revealing contamination in melon agroecosystems. Risk assessment for bees should consider long-term exposure effects of pesticides in both pollen and nectar, and the potential synergies among pesticide formulations. Acetamiprid, chlorpyrifos, and oxamyl at residue level concentration did not show adverse effects on bumblebees in terms of worker mortality, drone production, and drone size in the micro-colony bioassay.

Summary: Over time, intensification of agricultural systems has led to declines in biodiversity and ecosystem services, negatively impacting food production and security. Diversifying current farming systems through agroforestry practices can potentially mitigate these harmful impacts by providing suitable habitat for native pollinators and thus maintaining pollination services. This review synthesizes the findings of previous studies and highlights that agroforestry generally promotes or maintains pollination services compared to conventional agriculture, supporting the perspective that it represents a sustainable alternative. Future research should focus on understanding the effects of crop management intensity, irrigation, and organic inputs on pollination services.

Summary: This study compared pollen collection in introduced populations of Osmia cornuta and Bombus terrestris in orchards, and analyzed the effects of local and landscape floral context. The results showed that O. cornuta collected a greater proportion of fruit tree pollen than B. terrestris and was not influenced by the availability of alternative flower resources. Therefore, introducing managed O. cornuta populations in orchards to supplement pollination services is compatible with agri-environmental measures to promote wild pollinators.

Summary: This study analyzes the combined effects of climate warming and sublethal insecticide exposure on Osmia cornuta bees. The results show that warm wintering temperatures cause weight loss, lipid consumption, and fat body depletion in bees, making them more sensitive to pesticides. Additionally, high doses of insecticide impair the bees' ability to respond to light, reduce syrup consumption, and shorten their lifespan.
