PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

FEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Evaluation of two wheat cropping systems for enhancing biological control of the wheat thrips, Haplothrips tritici (Thys.: Phlaeothripidae) [PDF]

نامه انجمن حشره‌شناسی ایران, 2013
The wheat thrips, Haplothrips tritici Kurd., is an important pest of wheat crop, Triticum aestivum L., in Ardabil region, northwestern Iran. Strip cropping of wheat and alfalfa, Medicago sativa L., is a suitable strategy for improving the effectiveness ...

Measuring the conservation value of tropical primary forests : the effect of occasional species on estimates of biodiversity uniqueness [PDF]

, 2010
Background Developing effective conservation plans for multi-functional landscapes requires an accurate knowledge of the relative conservation value of different land-uses.

α‐Synuclein aggregation landscape from phase separation to neurotoxic intermediates

FEBS Letters, EarlyView.
Alpha‐synuclein aggregation in Parkinson's disease involves a complex landscape of transient intermediates, including oligomers, fibrils and liquid–liquid phase separation (LLPS). A view is emerging in which LLPS maturation into solid‐like condensates may contribute to the formation of neurotoxic species.

Non-native invasive beetle alters structure of a riparian bird community in a biodiversity hotspot

Frontiers in Ecology and Evolution
A serious emerging threat to southern California riparian ecosystems is the invasive shot hole borer (Euwallacea spp.; SHB), a non-native beetle that cultivates a pathogenic fungus that kills trees of 66 reproductive host species.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Using causal diagrams and superpopulation models to correct geographic biases in biodiversity monitoring data

Methods in Ecology and Evolution
Biodiversity monitoring schemes periodically measure species' abundances and distributions at a sample of sites to understand how they have changed over time. Often, the aim is to infer change in an average sense across some wider landscape. Inference to

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Avian and Mammalian Diversity and Abundance in Jhalana Reserve Forest, Jaipur, India

Animals
We utilized camera traps to evaluate animal diversity, relative abundance, and the extent of anthropogenic activities in the Jhalana Reserve Forest (JRF), located in Jaipur, with a population of 3.9 million people. Between November 2017 and November 2019,

Prioritizing Management of Non-Native Eurasian Watermilfoil Using Species Occurrence and Abundance Predictions

Diversity, 2020
Prioritizing the prevention and control of non-native invasive species requires understanding where introductions are likely to occur and cause harm. We developed predictive models for Eurasian watermilfoil (EWM) (Myriophyllum spicatum L.) occurrence and
