Different factors limit early‐ and late‐season windows of opportunity for monarch development

recommendations! Published in 2022 at "Ecology and Evolution"

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.

recommendations! Published in 2022 at "Ecology and Evolution"

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

recommendations! Published in 2022 at "Ecology and Evolution"

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.

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.

Mapping monarch seasonal breeding patterns in Eastern North America to inform mowing strategies for roadsides and other rights-of-ways

DOI: 10.1007/s10841-025-00676-6

Abstract: Monarch populations have declined precipitously over the past decades, largely due to the loss of their breeding host plant, milkweed. One mitigation strategy is to plant milkweed along rights-of-ways. However, many rights-of-ways undergo routine mowing,… read more here.

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

recommendations! Published in 2018 at "Journal of Chemical Ecology"

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.

recommendations! 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.

DOI: 10.1073/pnas.2417524121

Abstract: Multiple hypotheses have been put forth to understand why defense chemistry in individual plants is so diverse. A major challenge has been teasing apart the importance of concentration vs. composition of defense compounds and resolving… read more here.

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.
