DOI: 10.1002/ece3.9039
Abstract: Abstract Seasonal windows of opportunity are intervals within a year that provide improved prospects for growth, survival, or reproduction. However, few studies have sufficient temporal resolution to examine how multiple factors combine to constrain the… read more here.

DOI: 10.1002/ece3.9131
Abstract: Abstract Interacting species are experiencing disruptions in the relative timing of their key life‐history events due to climate change. These shifts can sometimes be detrimental to the fitness of the consumer in trophic interactions but… read more here.

Seasonal plasticity in morphology and metabolism differs between migratory North American and resident Costa Rican monarch butterflies

DOI: 10.1002/ece3.9796
Abstract: Environmental heterogeneity in temperate latitudes is expected to maintain seasonally plastic life-history strategies that include the tuning of morphologies and metabolism that support overwintering. For species that have expanded their ranges into tropical latitudes, it… read more here.

Video surveillance reveals a community of largely nocturnal Danaus plexippus (L.) egg predators

DOI: 10.1007/s10841-020-00248-w
Abstract: Monarch butterfly (Danaus plexippus L.) declines in eastern North America have prompted milkweed host plant restoration efforts in non-agricultural grasslands. However, grasslands harbor predator communities that exert high predation pressure on monarch eggs and larvae.… read more here.

The Effects of Milkweed Induced Defense on Parasite Resistance in Monarch Butterflies, Danaus plexippus

DOI: 10.1007/s10886-018-1007-4
Abstract: Many plants express induced defenses against herbivores through increasing the production of toxic secondary chemicals following damage. Phytochemical induction can directly or indirectly affect other organisms within the community. In tri-trophic systems, increased concentrations of… read more here.

DOI: 10.1007/s12293-016-0211-4
Abstract: Recently, inspired by the migration behavior of monarch butterflies in nature, a metaheuristic optimization algorithm, called monarch butterfly optimization (MBO), was proposed. In the present study, a novel chaotic MBO algorithm (CMBO) is proposed, in… read more here.

Patterns and causes of oviposition in monarch butterflies: Implications for milkweed restoration
Sign Up to like & getrecommendations! Published in 2018 at "Biological Conservation"
DOI: 10.1016/j.biocon.2017.10.019
Abstract: Abstract Effective habitat restoration requires an understanding of species habitat preferences and the associated mechanisms driving those preferences. We examined the patterns and causes of oviposition preference in the monarch butterfly, a rapidly declining species,… read more here.

DOI: 10.1016/j.ecolind.2020.106592
Abstract: Abstract The deleterious anthropogenic impact on animals is often hidden and not revealed in indexes of mortality in populations. Hence, animal monitoring should not only involve population numbers and survival, but also the individual physiological… read more here.

Non-migratory monarch butterflies, Danaus plexippus (L.), retain developmental plasticity and a navigational mechanism associated with migration

DOI: 10.1093/biolinnean/blx148
Abstract: Monarch butterflies are best known from their migratory North American range, although many resident, year-round breeding populations are established throughout the world. Here, we evaluate two non-exclusive hypotheses for the loss of migration in resident… read more here.

Abstract: Many insects are in clear decline, with monarch butterflies (Danaus plexippus) drawing particular attention as a flagship species. It is well documented that, among migratory populations, numbers of overwintering monarchs have been falling across several… read more here.
