Increased Serum Neurofilament Light Chain Levels in Parkinson's Disease Patients Carrying the p.A53T SNCA Mutation: Data from the Parkinson's Progression Markers Initiative Study

open access: yesMovement Disorders, EarlyView.
Abstract Background Serum neurofilament light chain (NfL) levels, a marker of axonal damage, are generally elevated in neurodegenerative conditions, but results in idiopathic Parkinson's disease (iPD) have been inconsistent. The p.A53T SNCA mutation usually leads to a severe form of PD.

Defense heterosis as a novel plant protection strategy: From theory to breeding practice

open access: yesNew Plant Protection, EarlyView.
Defense heterosis, the enhanced disease resistance of hybrids compared to their parents, has evolved from early observations of hybrid vigor to a novel research concept. Advances are now clarifying its diverse genetic and molecular mechanisms across various plant–pathogen interactions.

The disruption of seed dispersal networks: disentangling the effects of habitat loss and fragmentation

open access: yesOikos, EarlyView.
Seed dispersal by frugivores is a central process linking plant reproduction, animal foraging, population persistence, and ecosystem resilience. Currently, the spatial template sustaining these interactions is rapidly reconfigured by habitat loss and fragmentation promoted by human activity.

Open-back Shoes from the Southern Crypt in Piaseczno, Pomerania Province

open access: yesActa Universitatis Lodziensis: Folia Archaeologica, 2020
A discussion on modern shoes is limited on account of the scarcity of sources provided by archaeological research. This gap is to a certain extent filled by museum collections and iconography.

Understanding contingency in wolf‐mediated livestock predation across a mosaic of land uses: An agent‐based modelling approach

open access: yesPeople and Nature, EarlyView.
Abstract The return of grey wolves to multi‐use landscapes in North America and Europe raises concerns over accompanying risks of livestock predation. While local‐level risk factors have received attention, it is difficult to explore the role that landscape‐scale variables, such as landscape connectivity, play in driving livestock losses.

Capacity and limitations of US wild meat donation programmes

open access: yesPeople and Nature, EarlyView.
Abstract Historically, sharing of wild harvests to facilitate food security followed concepts of kin selection and reciprocal altruism. However, cultural shifts have reduced access to foods for some populations in modern times. Cultural altruism through sustainably harvested wild meat donation programmes (WDPs) can reduce food and nutritional ...

The magnitude and economic replacement value of wild meat obtained from ‘recreational’ big game hunting in the United States

open access: yesPeople and Nature, EarlyView.
Abstract Meat production has notable benefits for food security, nutrition and various production economies, but has elicited substantial negative environmental impacts. Recreational hunting provides an alternative to agricultural meat production for over 24 million hunters worldwide.

First microscopic and molecular detection of A. phagocytophilum in mules in Iraq [PDF]

open access: yesIraqi Journal of Veterinary Sciences
Anaplasma phagocytophilum, a multi-host pathogen, causes granulocytic anaplasmosis. A total of 50 mules were examined by collecting 50 blood samples by forming blood smears.

When does category spanning hurt or help producers?

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary Scholars have theorized many factors shaping whether category spanning helps or hurts producers. We first synthesize evidence by meta‐analyzing 25 years of empirical research, which reveals a null effect of spanning on average, yet with significant subsample heterogeneity. To unpack it, we theorize and find that spanning hurts

Pseudorandomised controlled trial of a novel navel barrier solution versus 10% iodine to protect navel and ear tag sites of neonatal lambs

open access: yesVeterinary Record, EarlyView.
Abstract Background During lambing, 10% iodine is often used to protect neonatal navel and ear tag sites. The evidence for its effectiveness is sparse. Recently, a specific navel barrier solution (NBS) was developed. Here, an in vivo field trial compared the two treatments. Methods Ten farms reported data from 6840 lambs. The navel and ear tag sites of
