DOI: 10.1002/ece3.8791
Abstract: Abstract Host density is an important factor when it comes to parasite transmission and host resistance. Increased host density can increase contact rate between individuals and thus parasite transmission. Host density can also cause physiological… read more here.

Lack of evidence for a fine‐scale magnetic map sense for fall migratory Eastern North American monarch butterflies (Danaus plexippus)

DOI: 10.1002/ece3.9498
Abstract: Abstract How first‐time animal migrants find specific destinations remains an intriguing ecological question. Migratory marine species use geomagnetic map cues acquired as juveniles to aide long‐distance migration, but less is known for long‐distance migrants in… read more here.

DOI: 10.1016/j.beproc.2022.104630
Abstract: Inbreeding is generally thought to have negative consequences for organismal health. However, despite the potential fitness effects, it remains surprisingly common among wild populations. In many cases, the complex factors that underlie mating dynamics make… read more here.

DOI: 10.1080/00222933.2018.1510057
Abstract: Long-term springtime counts of immature and adult monarch butterflies and their Asclepias humistrata host plants in north-central Florida reveal a close relationship between the milkweed’s phenology and the butterfly’s spring remigration from Mexico. Remigrant adults… 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.

DOI: 10.1093/conphys/coab032
Abstract: Recent work suggests captive-reared monarch butterflies lose their capacity to fly southward in fall, questioning the value of captive rearing. We show that, in contrast to captive-reared monarchs flown in a flight simulator, monarchs reared… read more here.

DOI: 10.1111/gcb.15957
Abstract: Eastern North American monarch butterflies (Danaus plexippus) embark on a yearly migration between summer breeding grounds in the northern United States and southern Canada and overwintering sites in central Mexico, traveling up to 4300 km.… read more here.

DOI: 10.1111/gcb.16282
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.

DOI: 10.1111/gcb.16349
Abstract: Climate change poses a unique threat to migratory species as it has the potential to alter environmental conditions at multiple points along a species' migratory route. The eastern migratory population of monarch butterflies (Danaus plexippus)… read more here.
