Summary: Since the 1960s, scientists have observed the winter breeding behavior of North American monarch butterflies, particularly in areas with non-native milkweed plants. Warmer climates and the presence of milkweed plants and suitable temperatures for immature monarch development are key factors contributing to this behavior. The implications of winter breeding differ in the eastern and western regions due to differences in migration ecology, milkweed species, and climate changes.

Summary: The study revealed that first generation monarch survival was high in a complex arthropod community in north Texas, with survival being influenced by the presence of a greater number and variety of non-predatory arthropods on host plants. This suggests that monarch conservation efforts should focus on promoting diverse functional arthropod communities.

Summary: Anthropogenic disturbance is causing global biodiversity loss, affecting the monarch butterfly which relies on milkweed. Planting ornamental milkweed in urban landscapes seems beneficial for the conservation of monarch butterflies. However, sap-feeding insect herbivores, such as the oleander aphid, can negatively impact monarch conservation efforts by reducing plant quality and triggering plant defenses.

Summary: Anthropogenic disturbance is causing global biodiversity loss, including the specialized monarch butterfly. In response, ornamental milkweed plantings are becoming more common in urban landscapes and have been shown to have conservation value for monarch butterflies. However, sap-feeding insect herbivores, such as the oleander aphid, often reach high densities on these plants. Aphid-infested milkweed may hinder monarch conservation efforts by reducing host plant quality and inducing plant defenses.

Summary: The mechanism of milkweed cardenolides sequestration in monarch butterflies and how related species cope with these toxins are still unknown. This study used mass spectrometry imaging to compare the distribution of cardenolides in caterpillars of monarch butterflies and common crow butterflies. The results showed that monarch butterflies can sequester cardenolides from milkweed, while no cardenolides were found in the tissues of common crow butterflies. The study also identified the transport and storage sites of cardenolides in monarch butterflies.

Summary: Population dynamics, persistence, and distribution are influenced by animal movement behavior and resource configuration. Understanding the movement behavior of monarch butterflies can help restore breeding habitats and increase population size. Empirical data can be incorporated into simulation models for larger-scale population responses.

Summary: This study reexamines the differences between western and eastern monarch larvae by analyzing the melanism of online photographs submitted by the public. The results show that there is no significant difference in melanism levels between eastern and western larvae, and there are possible discrepancies with a previous experimental study. Additionally, the color of wild larvae appears to be lighter than captive-reared larvae.

Summary: In this review, the author discusses the controversial activity of rearing monarch butterflies in captivity and later releasing them, due to potential negative effects on the wild population. The review also examines the current evidence for how captive rearing and breeding could impact monarch fitness in the wild, as well as the implications for conserving monarchs and other species.

Summary: Predicting species' responses to future climate conditions is crucial for conservation and policy-making. This study used multiple global climate models to project the population fluctuations of the monarch butterfly and found differences between trimmed and complete ensembles, with the trimmed ensemble providing more useful information.

Summary: The study investigated the long-term trends in fall migration phenology of monarch butterflies in Ontario, Canada and the local long-term trends in weather covariates. The results showed that monarch migration timing and weather covariates have been consistent over time, contradicting a similar study in Cape May, New Jersey.

Summary: Neonicotinoids are widely used insecticides in North America, with studies showing negative effects on bees. Monarch butterflies, known for their long-distance migrations, were found to be negatively impacted by neonicotinoids, with effects dependent on the milkweed species they feed on. Results suggest that monarchs can tolerate low neonicotinoid doses, but experience detrimental effects at higher doses, influenced by the type of milkweed host plant. This study highlights the potential role of host plant species in reducing insecticide residue and calls for further investigation.

Summary: This study examined the environmental persistence and thermal tolerance of a debilitating protozoan parasite that infects monarch butterflies. The findings show that warmer temperatures decrease parasite viability over time, different parasite genotypes exhibit variability in thermal tolerance, and there is no clear relationship between environmental persistence and within-host replication. The study also found that dormant spores can survive for many months under cooler conditions, but heat dramatically shortens the window of transmission for this butterfly parasite.

Summary: This study investigates the effects of neonicotinoids on non-target nectar-feeding insects, particularly monarch butterflies. The results show that adult monarch butterflies can tolerate field-relevant doses of neonicotinoids with minimal effects on their survival, reproduction, flight, and behavior. However, higher doses of neonicotinoids can significantly impact monarch butterflies' nectar consumption, survival, flight performance, and reaction time.
