Artificial Light at Night Affects Larval Growth Without Altering Survival or Pupation in Spongy Moth (Lymantria dispar dispar)

Ecology and Evolution, Volume 15, Issue 10, October 2025.
In this study, we investigated how artificial light at night (ALAN) affects larval development in the invasive spongy moth. Caterpillars exposed to 3700 K LED light reached higher body masses than those under 2200 K or darkness, suggesting ALAN may enhance growth and influence population dynamics.

Non-target effects of clothianidin on monarch butterflies

The Science of Nature, 2015
Monarch butterflies (Danaus plexippus) frequently consume milkweed in and near agroecosystems and consequently may be exposed to pesticides like neonicotinoids. We conducted a dose response study to determine lethal and sublethal doses of clothianidin using a 36-h exposure scenario.

Honest signalling in predator–prey interactions: Testing the resource allocation hypothesis

Functional Ecology, Volume 39, Issue 10, Page 2833-2848, October 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Warning signals are honest if they reliably deliver information about prey unprofitability to predators. One potential mechanism that may create and maintain a positive relationship between the strength of signals and defence is the resource allocation between these ...

Zeitgeist and Ortgeist: Time and Place in Institutional Creation

British Journal of Management, Volume 36, Issue 4, Page 1694-1708, October 2025.
Abstract How are institutions created is one of the most interesting questions in institutional theory. Some strands of literature favour heroic explanations: mythologizing individuals with vision, tenacity and drive and putting these individuals on the pedestal of the institution.

Neither source nor trap: Urban gardens as habitat for nonmigratory monarch butterflies in Northern California

Ecosphere
Urban ecosystems can act as hotspots for diverse taxa, especially pollinators. However, it is not clear whether urban environments function as high‐quality habitat as opposed to demographic sinks or ecological traps.

The Importance of Shifting Disturbance Regimes in Monarch Butterfly Decline and Recovery

Frontiers in Ecology and Evolution, 2019
The Eastern migratory monarch butterfly has declined in recent decades, partly because widespread adoption of herbicide-resistant corn and soybean has nearly eliminated common milkweed from crop fields in the US Midwest.

‘Highly‐Informative’ Genetic Markers Can Bias Conclusions: Examples and General Solutions

Molecular Ecology Resources, Volume 25, Issue 7, October 2025.
ABSTRACT High‐grading bias is the overestimation power in a subset of loci caused by model overfitting. Using both empirical and simulated datasets, we show that high‐grading bias can cause severe overestimation of population structure, and thus mislead investigators, whenever highly informative or high‐FST markers are chosen (i.e., ascertained) and ...

Host Plants and Climate Structure Habitat Associations of the Western Monarch Butterfly

Frontiers in Ecology and Evolution, 2019
The monarch butterfly is one of the most easily recognized and frequently studied insects in the world, and has recently come into the spotlight of public attention and conservation concern because of declining numbers of individuals associated with both

Female Behaviour Drives Expression and Evolution of Gustatory Receptors in Butterflies [PDF]

, 2013
Secondary plant compounds are strong deterrents of insect oviposition and feeding, but may also be attractants for specialist herbivores. These insect-plant interactions are mediated by insect gustatory receptors (Grs) and olfactory receptors (Ors).
