Do Neotropical adult dobsonflies (Megaloptera, Corydalidae) feed on solid material in the nature? Information from a gut content study

The study examines gut contents of two Neotropical dobsonfly species to determine if they consume solid food, finding no significant solid material and suggesting reliance on liquid sources or larval fat reserves.

Effects of diversifying the planting period of maize on herbivorous and their natural enemies

This study examines how varying maize planting periods affects herbivorous insect and their natural enemies' abundance, finding significant differences in specific taxa between early and late planting periods.

Potential geographic distribution and ecological niche of New World dobsonflies (Megaloptera, Corydalidae): the case of the Neartic-Neotropical transition zone

The paper models the geographic distribution and ecological niche of New World dobsonflies, finding that mountainous areas and warm climates with high precipitation influence their range, with precipitation being key for dispersal.

Plant morphometry matches beetle diversity: effects of natural adjacent vegetation on grain Amaranth crop under small-holder conditions

This study examines how adjacent vegetation affects Amaranth crop morphology and beetle diversity in small-holder farming, finding positive plant growth and beetle richness responses to natural habitats.

Habitat complexity in organic olive orchards modulates the abundance of natural enemies but not the attraction to plant species

The paper evaluates how habitat complexity and plant species affect arthropod abundance and richness in organic olive orchards using statistical models.

Ground cover presence in organic olive orchards affects the interaction of natural enemies against Prays oleae, promoting an effective egg predation

This study shows that mowed ground cover in organic olive orchards enhances egg predation of the olive moth P. oleae by increasing natural enemy abundance and effectiveness.

Single Cell Transcriptomics of Pancreatic Cancer Precursors Demonstrates Epithelial and Microenvironmental Heterogeneity as an Early Event in Neoplastic Progression

This study uses single-cell RNA sequencing to analyze transcriptomic changes in pancreatic cancer precursors, revealing epithelial and microenvironmental heterogeneity during progression to cancer.
