Monarch butterfly population decline in North America: identifying the threatening processes [PDF]
Royal Society Open Science, 2017 The monarch butterfly (Danaus plexippus) population in North America has sharply declined over the last two decades. Despite rising concern over the monarch butterfly's status, no comprehensive study of the factors driving this decline has been conducted.

Northern cod (Gadus morhua) movement: insights from acoustic telemetry and genomics
Journal of Fish Biology, EarlyView.Abstract Knowledge of the timing and diversity of fish movements within a commercially exploited stock complex is required to ensure the sustainability of fisheries. Although migration can be driven by environmental factors, genomic mechanisms also play an important role in this complex life‐history trait. The northern cod (Gadus morhua) stock complex,

European Journal of Entomology, 2003 Ornithologists in Finland recorded the autumn migration of the Red Admiral butterfly, Vanessa atalanta (L.). In the best year, 1998, 1240 migrants were counted from a bird tower in September.

Global Change Biology Communications, Volume 1, Issue 1, March 2026.Warming caused a significant decrease in monarch fat mass, likely due to an observed reduction in sucrose concentration caused by warming of the nectar. Since sucrose fuels fall migration and overwintering, our results suggest climate warming may reduce migration success and overwinter survival.

New Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 1, March 2026.Dragon fruit (pitaya; Hylocereus undatus) is a promising, new high‐value crop in New Zealand. The large nocturnal flowers open for one night and close early in the morning the following day over a 3‐ to 6‐month long flowering period. In dragon fruit's native range, hawkmoths and bats are key nocturnal pollinators, and honey bees visit flowers during ...

Insect Conservation and Diversity, Volume 19, Issue 2, Page 380-392, March 2026.We surveyed 119 stands of common milkweed (Asclepias syriaca) across an urbanisation gradient to investigate how restored garden habitat might ameliorate the negative effects of urbanisation on specialist herbivores. Surprisingly, we found most herbivores (including the monarch butterfly) had greater occupancy on common milkweed towards an urban centre.

Resource Availability Modulates Gene Expression Across Life Stages in a Migratory Butterfly
Molecular Ecology, Volume 35, Issue 5, March 2026.ABSTRACT Natural populations are in constant need of balancing resource allocation to compensate for seasonal environmental variation. In many insects, a well‐established trade‐off between migration and reproduction exists. While this trade‐off has been characterised phenotypically for decades, the underlying regulatory pathways are poorly understood ...
