Population and species neighbor identity impact trait–trait relationships and plant performance

open access: yesPopulation Ecology, EarlyView.
We evaluated how populations and species identity influence plant performance and trait outcomes in mixtures, and assessed trait variation among populations of two forb species native to the western United States (Dieteria canescens and Heterotheca villosa) following three interaction treatments (single‐population monoculture, two‐population mixture ...

Some Relative Humidity Reactions of the Wood-Louse, Cylisticus Convexus (Isopoda: Porcellionidae) in an Olfactometer [PDF]

open access: yes, 2017
Generally, wood-lice are confined to habitats where the saturation deficit is low and damp surfaces are available. Cylisticus convexus (De Geer) is one of many species that are found in a relatively wet habitat (Edney, 1954).

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

open access: yesPopulation Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Phylogenetic relationship between the endosymbiont “Candidatus Riesia pediculicola” and its human louse host

open access: yesParasites & Vectors, 2022
Background The human louse (Pediculus humanus) is a haematophagous ectoparasite that is intimately related to its host. It has been of great public health concern throughout human history.

System-specific salmon louse infestation thresholds for salmon farms to minimize impacts on wild sea trout populations

open access: yesAquaculture Environment Interactions, 2021
Salmon lice Lepeophtheirus salmonis from aquaculture can cause negative impacts on sea trout Salmo trutta and other wild salmonids. Long-term records from 5 Irish rivers were used to explore relationships between annual sea trout runs and estimated total

Making tau amyloid models in vitro: a crucial and underestimated challenge

open access: yesFEBS Letters, EarlyView.
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

Comparative analyses of the fragmented mitochondrial genomes of wild pig louse Haematopinus apri from China and Japan

open access: yesInternational Journal for Parasitology: Parasites and Wildlife, 2022
The wild pig louse Haematopinus apri is one of the commonest ectoparasites of wild pigs. In the present study, the entire mitochondrial (mt) genome of wild pig louse H.

Tonal Activity in Kara, an Austronesian language spoken in New Britain [PDF]

open access: yes, 2004
This paper presents the results of a small phonetic investigation of tonal activity in Kara, a little-known Austronesian language spoken in Papua New Guinea. Sketchy reports of some kind of tonal contrast in this language surfaced in the 1960s and 1970s,

Evolutionary interplay between viruses and R‐loops

open access: yesFEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.
