Year-round weather alters nest-provisioning rates in a migratory owl. [PDF]

Ecol Evol, 2023
Using 17 years of nest observations, we investigated how annual weather patterns affected Flammulated Owl nesting and foraging behaviors during the breeding season. Nest‐provisioning rates were higher in dry and cold years compared to wet and warm years, but the weather did not affect nestling growth rates, adult mass, division of labor, or nest ...

Disease-related population declines in bats demonstrate non-exchangeability in generalist predators. [PDF]

Ecol Evol, 2022
While many bat species are known to function as suppressors of arthropod abundance, including several economically important agricultural pest taxa, the broader ecological consequences of disease‐related bat declines have not been fully assessed in many regions.

The clockwork of insect activity: Advancing ecological understanding through automation. [PDF]

J Anim Ecol
The study demonstrates that time‐controlled insect sampling using an automated Malaise trap in combination with metabarcoding allows for the observation and documentation of taxon‐specific activity patterns. These recorded activity patterns can provide valuable insights into the underlying ecological processes, including parasitoid–host relationships ...

Classifying the unknown: Insect identification with deep hierarchical Bayesian learning

Methods in Ecology and Evolution, Volume 14, Issue 6, Page 1515-1530, June 2023., 2023
Abstract Classifying insect species involves a tedious process of identifying distinctive morphological insect characters by taxonomic experts. Machine learning can harness the power of computers to potentially create an accurate and efficient method for performing this task at scale, given that its analytical processing can be more sensitive to subtle

Artificially perforated holes in stems of small hogweed mimic ecosystem engineering by a moth

Journal of Applied Entomology, Volume 146, Issue 10, Page 1302-1310, December 2022., 2022
Abstract Ecosystem engineers are species that manipulate the physical state of ecosystems and thereby affect the behaviour and ecology of other species. Mature larvae of the parsnip webworm, Depressaria radiella Goeze, chew holes in the hollow stems of Heracleum sphondylium L. into which they pupate.

The unresolved phylogenomic tree of butterflies and moths (Lepidoptera): Assessing the potential causes and consequences

Systematic Entomology, Volume 47, Issue 4, Page 531-550, October 2022., 2022
Phylogenomics has helped us resolve much of the Lepidoptera tree of life, but the relationships among the superfamilies within Ditrysia, containing 98% of the order's species richness, remain unresolved. One of the unresolved questions is the phylogenetic position of the large microlepidopteran superfamily Gelechioidea, whose placement depends on the ...

Insectivorous bats selectively source moths and eat mostly pest insects on dryland and irrigated cotton farms

Ecology and Evolution, Volume 10, Issue 1, Page 371-388, January 2020., 2020
Insectivorous bats consumed consistent proportions of Lepidoptera (frequency and abundance) over the cotton‐growing season, despite a pronounced temporal shift in the composition of available arthropod prey orders in cotton crops. Abstract Insectivorous bats are efficient predators of pest arthropods in agroecosystems.

No guts, no glory: Gut content metabarcoding unveils the diet of a flower‐associated coastal sage scrub predator

Ecosphere, Volume 10, Issue 5, May 2019., 2019
Abstract Invertebrate generalist predators are ubiquitous and play a major role in food‐web dynamics. Molecular gut content analysis (MGCA) has become a popular means to assess prey ranges and specificity of cryptic arthropods in the absence of direct observation.

Geographic Variation in the Diet of Red Knot (Calidris canutus) Chicks Reflects Local Prey Communities

Journal of Biogeography, Volume 53, Issue 3, March 2026.
ABSTRACT Aim To describe and compare the diets of an Arctic‐breeding shorebird, the Red Knot (Calidris canutus), across three geographically distinct breeding sites. We aimed to document the dietary patterns and identify key prey groups that characterise each population's foraging ecology.

Integrating Sanger and next‐generation sequencing data sheds light on phylogenetic relationships among gelechioid moths (Lepidoptera: Gelechioidea)

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
The maximum‐likelihood analysis of a phylogenomic dataset of 1767 protein‐coding genes from 57 ingroup taxa yields a robust family‐level topology for Gelechioidea, revealing novel among‐family relationships. Integration of the phylogenomic dataset with the available taxon‐rich Sanger‐sequenced data provides insights into the monophyly of the 20 ...
