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

Ecology and Evolution
North American sapsuckers are considered double keystone species because they (1) excavate nest cavities that are used by other birds, small mammals, and invertebrates, and (2) create and maintain sap wells, a temporary nutritional resource available to ...

Diversity and Distribution of Mites (ACARI) Revealed by Contamination Survey in Public Genomic Databases [PDF]

Animals, 2023
Acari (mites and ticks) are a biodiverse group of microarthropods within the Arachnida. Because of their diminutive size, mites are often overlooked. We hypothesized that mites, like other closely related microorganisms, could also contaminate public ...

Recent advances on phylogenomics of gymnosperms and a new classification [PDF]

Plant Diversity, 2022
Living gymnosperms comprise four major groups: cycads, Ginkgo, conifers, and gnetophytes. Relationships among/within these lineages have not been fully resolved.

The evolutionary history of the ancient weevil family Belidae (Coleoptera: Curculionoidea) reveals the marks of Gondwana breakup and major floristic turnovers, including the rise of angiosperms [PDF]

eLife
The rise of angiosperms to ecological dominance and the breakup of Gondwana during the Mesozoic marked major transitions in the evolutionary history of insect-plant interactions.

The Systematics and Evolution of Gymnosperms with an Emphasis on a Few Problematic Taxa [PDF]

Plants
Gymnosperms originated in the Middle Devonian and have experienced a long evolutionary history with pulses of speciation and extinction, which resulted in the four morphologically distinct extant groups, i.e., cycads, Ginkgo, conifers and gnetophytes ...

Assessment of the diet of the critically endangered northern hairy-nosed wombat (Lasiorhinus krefftii) using DNA metabarcoding. [PDF]

Ecol Evol, 2023
Diet of the critically endangered northern hairy‐nosed wombat was assessed. They are generalist herbivores consuming mostly grasses followed by legumes. The northern hairy‐nosed wombat diet is significantly different across seasons and sites.

NGATHA carpel development genes evolved in the common ancestor of seed plants. [PDF]

Plant J
SUMMARY The evolution of the carpel, the defining feature of angiosperms, remains a fundamental question in plant biology. Understanding how this organ originated is crucial because it underpins the reproductive success and diversity of flowering plants.

Indigenous peoples and local community reports of climate change impacts on biodiversity. [PDF]

Conserv Biol
Abstract Climate change impacts on biodiversity have been primarily studied through ecological research methods, largely ignoring other knowledge systems. Indigenous and local knowledge systems include rich observations of changes in biodiversity that can inform climate change adaptation planning and environmental stewardship.

Phylogenetic reconciliation provides new insights into the evolutionary diversification of the glutamine synthetase gene family in seed plants. [PDF]

FEBS J
Phylogenetic analyses of glutamine synthetase (GS) in seed plants revealed that all three major evolutionary lineages (GS2, GS1a, and GS1b) must have been present in the common ancestor, with GS2 being the first lineage to diverge. Unlike GS1b, GS1a and GS2 are usually single‐copy genes, even though they underwent duplications that resulted in ...

Using eDNA metabarcoding to understand the effect of fire on the diet of small mammals in a woodland ecosystem. [PDF]

Ecol Evol, 2022
Information regarding diet changes over time after disturbance is lacking for many animals living in habitats prone to disturbances such as fires. DNA metabarcoding is a versatile molecular method that allows simultaneous characterization of many biotas using taxonomically informative barcode regions.
