Gene content evolution in the arthropods [PDF]

open access: yes, 2020
Arthropods comprise the largest and most diverse phylum on Earth and play vital roles in nearly every ecosystem. Their diversity stems in part from variations on a conserved body plan, resulting from and recorded in adaptive changes in the genome ...

Honey-derived Paenibacillus spp. with potential to affect bee brood development in Apis mellifera: Are they a new threat to honey bees?

open access: yesVirulence
Honey bees are important pollinators in both agriculture and ecosystems, and their health is essential for sustainable human development. Although only two bacteria, Paenibacillus larvae and Melissococcus plutonius, have been identified as bacterial ...

Secondary Compounds in Milkweed Nectar Negatively Impact Thermal Tolerance in Bumble Bees

open access: yesEcology and Evolution, Volume 15, Issue 11, November 2025.
This study shows that exposure to cardenolide toxins in floral nectar impacts heat tolerance in bumble bees at field‐realistic doses. Various honeys, aside from milkweed honey, did not impact heat tolerance in these bees. These data suggest that compounds in their diet may impact resilience of bees to global warming and that milkweed‐specialists may be

Multiomics Reveal Associations Between CpG Methylation, Histone Modifications and Transcription in a Species That has Lost DNMT3, the Colorado Potato Beetle

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 7, Page 454-469, November 2025.
Despite lacking DNMT3, EM‐seq revealed CpG methylation in the Colorado potato beetle. CUT&Tag analysis showed an association of H3K36me3 and H3K27ac with transcription, with H3K36me3 mirroring CpG methylation, demonstrating epigenetic flexibility.

What is a hologenomic adaptation? Emergent individuality and inter-identity in multispecies systems [PDF]

open access: yes, 2020
Contemporary biological research has suggested that some host–microbiome multispecies systems (referred to as “holobionts”) can in certain circumstances evolve as unique biological individual, thus being a unit of selection in evolution.

Cash, Credit, or Kin? Financing Pathways and the Uneven Sustainability of Off‐Grid Solar Electrification in Tanzania and Malawi

open access: yesSustainable Development, Volume 33, Issue S1, Page 427-443, November 2025.
ABSTRACT Solar home systems (SHSs) are celebrated as a technological antidote to sub–Saharan Africa's chronic electricity deficits, yet the financial and social mechanisms that move them from warehouse to household remain underexplored. Drawing on 157 interviews with SHS owners in Tanzania and Malawi, this study examines the financial pathways used to ...

What Do Studies of Insect Polyphenisms Tell Us about Nutritionally-Triggered Epigenomic Changes and Their Consequences? [PDF]

open access: yes, 2015
Many insects are capable of remarkable changes in biology and form in response to their environment or diet. The most extreme example of these are polyphenisms, which are when two or more different phenotypes are produced from a single genotype in ...
