Temperate forest heterogeneity decreases local and landscape‐scale spider diversity through habitat filtering despite increasing species turnover

Journal of Animal Ecology, EarlyView.
In a large‐scale German forest experiment, habitat heterogeneity increased spider turnover but reduced local alpha diversity through habitat filtering. Together, these effects lowered landscape‐scale spider diversity. As such, the study shows whether environmental heterogeneity increases or decreases biodiversity depends on the balance between habitat ...

The consequences of host heterogeneity for parasite transmission depend on how host infectiousness is determined

Journal of Animal Ecology, EarlyView.
This study proposes two contrasting scenarios for how host infectiousness is determined: recipient dependence and donor dependence. These scenarios fundamentally alter how host heterogeneity shapes parasite transmission, demonstrating that the process by which infectiousness is determined is crucial for understanding the consequences of host ...

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Effect of the microbiome on pathogen susceptibility across four Drosophilidae species

Insect Science, EarlyView.
Four Drosophilidae species were used to investigate how variation in the host microbiome influences susceptibility to infection. Microbial composition and abundance differed among species and treatments. The effects of microbiome manipulation on host survival were both species‐ and pathogen‐specific.

Neonicotinoid seed treatments do not consistently reduce insect feeding damage nor increase yields in Maryland soy

Agricultural and Forest Entomology, EarlyView.
We compared soybean plants from untreated and treated seeds across 4 sites and 3 years in Maryland. Neonicotinoid seed treatments (NST) provided little reduction in insect stippling damage and no reduction in chewing damage. NST did not result in increased plant biomass or bean yield. Abstract The use of neonicotinoid insecticides in seed treatments in

A Case of Lentigo Maligna Presenting as Repigmentation of Hair in a Scalp That Previously Underwent Radiotherapy for Tinea Capitis

Australasian Journal of Dermatology, EarlyView.
ABSTRACT Lentigo maligna has occasionally been noted to have the capacity to invade and repigment grey hairs. We present a case of a 78‐year‐old male who presented with a patch of brown hair on the vertex of the scalp in an area of previously white hair.
