Additional Siphonaptera Records From Small Mammals in the Central Upper Peninsula of Michigan [PDF]

open access: yes, 2018
Fleas were collected from mammals during the period 1990-1992 in two upper peninsula counties. Identified specimens were compared to existing distribution records for both parasite and host. Only those records which are newly documented for county, upper

Infection Models for Pine Wilt Disease on the Basis of Vector Behaviors

open access: yesPopulation Ecology, EarlyView.
Infection models for pine wilt disease without vector density were built to estimate the transmission coefficient of the pathogenic nematode. The models successfully simulated the annual change in the density of infected trees for four pine stands. ABSTRACT Pine wilt disease is caused by the pinewood nematode (Bursaphelenchus xylophilus Steiner et ...

Speciation Through the Lens of Population Dynamics: A Theoretical Primer on How Small and Large Populations Diverge

open access: yesPopulation Ecology, EarlyView.
Population size and dynamics fundamentally shape speciation by influencing genetic drift, founder events, and adaptive potential. Small populations may speciate rapidly due to stronger drift, whereas large populations harbor more genetic diversity, which can alter divergence trajectories. We highlight theoretical models that incorporate population size

On the Neotropical species of the spider genus Tekellina Levi, 1957 (Arachnida: Araneae: Synotaxidae)

open access: yesEuropean Journal of Taxonomy
The genus Tekellina Levi, 1957 is currently composed of ten species, six of which are Neotropical. They are small-sized spiders (0.9 to 1.5 mm), with a wide distribution, with a great diversity in the Neotropical Region and well represented in Brazil ...

The epithelial barrier theory proposes a comprehensive explanation for the origins of allergic and other chronic noncommunicable diseases

open access: yesFEBS Letters, EarlyView.
Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...

New records of mosses from Dominican amber [PDF]

open access: yes, 2001
Hypnum cupressiforme, Entodon macropus, Homalia glabella and Calyptothecium duplicatum are recorded as new from Dominican amber. Earlier records of Neckera spec. have to be transferred to Calyptothecium duplicatum. These records raise the total number of

Kryptochroma: a new genus of bark-dwelling crab spiders (Araneae, Thomisidae)

open access: yesEuropean Journal of Taxonomy, 2021
A recent phylogenetic analysis has shown that the genus Stephanopis comprises several different lineages of bark-dweller crab spiders. The ones with South American distribution that present a close relationship with other Neotropical genera like Epicadus,
