Exploring and validating observations of non-local species in eDNA samples. [PDF]

Ecol Evol, 2023
The sensitivity of DNA‐based methodologies provides great benefits while also carrying inherent risks of contamination, and subsequently false positives in the final datasets. Here, we present the observations of sequences assigned to presumed false positive non‐local species, investigate their likely origins, and discuss how best to resolve them ...

Commodity risk assessment of Crataegus monogyna plants from the UK. [PDF]

EFSA J, 2023
Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, plant products and other objects’. Taking into account the available scientific information, including the technical information provided by ...

Leaf volatile and nonvolatile metabolites show different levels of specificity in response to herbivory. [PDF]

Ecol Evol, 2023
We test how insect herbivore species, order, feeding guild and level of specialization correlate with the variation in induced plant responses. The induction of volatile and nonvolatile leaf metabolites shows different levels of specificity. Our results demonstrate how diverse responses to herbivores can contribute to the diversity of defensive plant ...

Scaling Relationships and Sexual Size Dimorphism Among the Body Parts of <i>Holotrichia oblita</i> (Coleoptera: Scarabaeidae). [PDF]

Ecol Evol
Females of Holotrichia oblita have larger wing loadings and shorter leg lengths compared to males. There are significant allometric relationships between body mass and body length, and between total elytra mass and total hind wing area. ABSTRACT Sexual dimorphism is common among insects.

Sapsucker Wells as a Keystone Nutritional Resource: Evaluating Methods for Detection of Secondary Sap Consumers. [PDF]

Ecol Evol
We used direct observations, camera traps, and environmental DNA (eDNA) to identify secondary consumers of sap from wells created by red‐naped (S. nuchalis) and Williamson's (S. thyroideus) sapsuckers among three groups of shrubs and trees in south‐central Colorado, USA.

Livestock shifts lepidopteran herbivore community due to intraguild elimination in Mediterranean agroforestry systems. [PDF]

Ecol Appl
Abstract Livestock grazing and trampling have been shown to reduce arthropod populations. Among arthropods, defoliating lepidopterans are particularly important for their impact on trees, the keystone structures of agroforestry systems. This study investigates the impact of livestock on the community of defoliating lepidopterans in agroforestry systems.

Increased cave use by butterflies and moths: a response to climate warming?

International Journal of Speleology, 2021
Between 2015 and 2019, the list of Lepidoptera from “cave” habitats (i.e., proper caves, rock shelters and artificial subterranean structures) in Austria grew from 17 to 62 species, although the effort of data collection remained nearly constant from the

Phylogenomics resolves major relationships of Catocala underwing moths

Systematic Entomology, Volume 48, Issue 4, Page 633-643, October 2023., 2023
Our molecular phylogeny of the charismatic underwing moth genus Catocala (Lepidoptera: Erebidae) recovers Catocala and Catocala + Ulotrichopus as monophyletic groups with strong support. Our mapping of larval host plant use onto our molecular phylogeny shows that the most recent common ancestor of Catocala likely fed on legumes.
