Eco-evolutionary dynamics in two-species mutualistic systems : one-sided population decline triggers joint interaction disinvestment
The interplay between ecological and evolutionary dynamics can create feedback that reinforces external disturbances and potentially threatens species’ coexistence. For example, plants might invest less into attracting insect pollinators (decreased flower or nectar production) and more into independence (increased selfing or vegetative reproduction) when faced with pollinator decline. This adaptiv
Multiple density-dependent processes shape the dynamics of a spatially structured amphibian population
Understanding the mechanisms that regulate the dynamics of spatially structured populations (SSP) is a critical challenge for ecologists and conservation managers. Internal population processes such as births and deaths occur at a local level, while external processes such as dispersal take place at an inter-population level. At both levels, density dependence is expected to play a critical role.
Resilience to climate variation in a spatially structured amphibian population
Understanding the impact of weather fluctuations on demographic parameters is of crucial interest to biodiversity research in a context of global climate change. Amphibians are valuable candidates for investigating this topic due to their strong physiological dependence on water availability and temperature. In this study, we took advantage of data from a long-term capture–mark–recapture (CMR) mon

Collapse and rescue of evolutionary food webs under global warming
Global warming is severely impacting ecosystems and threatening ecosystem services as well as human well-being. While some species face extinction risk, several studies suggest the possibility that fast evolution may allow species to adapt and survive in spite of environmental changes. We assess how such evolutionary rescue extends to multitrophic communities and whether evolution systematically p

Recognition, management, and patient perspectives of impulsive-compulsive disorders in Parkinson's disease
BackgroundImpulsive-compulsive disorders (ICDs) are commonly acknowledged as side effects of dopaminergic therapy in Parkinson’s disease (PD). While many large-scale studies have focused on prevalences and high-risk treatments, little is known about practical management of ICDs in clinical care and patients’ experiences.ObjectiveTo investigate how ICDs are recognized in clinical PD care, clinical
Television and the Labor Supply: Evidence from the Digital Television Transition in the UK
I exploit variation in the date of transition from analogue to digital television signal in the UK across more than 40,000 geographical units to investigate the causal impact of television on employment. Using an event study model, I find that the digital transition increases employment probabilities. The impact is driven by mothers, primarily through an increase in part-time employment. I also sh
Can Subsidies to Permanent Employment Change Fertility Decisions?
I examine the causal effect of incentives to permanent employment on fertility by exploiting exogenous variation in subsidies given by the Spanish local authorities to employers converting temporary jobs into permanent ones. The amount of the subsidy varies across regions, in the age and gender of the employees whose contracts are converted, and within these three dimensions over time. Using admin
The effect of TV viewing on children’s obesity risk and mental well-being: Evidence from the UK digital switchover
We examine the effect of screen-based activities on obesity and mental well-being for children, using a large survey dataset representative of the UK population and an event study model that exploits exogenous variation in the entry date of the digital television transition in the UK. The digital transition increased the number of available free television channels from 5 to 40, leading to a rise
Native-immigrant differences in the effect of children on the gender pay gap
This paper explores gender differences in the career paths of immigrant and native parents before and after childbirth using Spanish administrative data and an event study specification. I find an important gender pay gap emerging after childbirth for both immigrants and natives, and that the drivers of these gender pay gaps strongly differ between natives and immigrants: while children generate h
Just work for a just transition? : Degrowth and the future of dignified work
Precarious, flexibilised and informalised work has been a norm rather than the exception. Globally, formal employment, with a job contract, sick leave, vacation, rights to safe workspace, defined working hours, etc., has only been a reality for a minority. Much of the global workforce work outside formalised workspaces which include all types of economic activities deemed as ‘informal’, such as, s
Insiders, Outsiders, and the Constructed Limits to Social Rights in EU Law
This paper engages with limitations to social rights for different categories of migrants under EU law. By looking at how EU law construes accepted limitations to social rights and how the Court of Justice reviews such limitations, the paper suggests that there is room for different interpretation of limitations to social rights under secondary law in view of a more coherent understanding of their
Role of Tau and Amyloid-beta in autophagy gene dysregulation through oxidative stress
BACKGROUND: Alzheimer's disease (AD) is a prevalent neurodegenerative disorder characterized by memory impairment and cognitive decline. Our previous research has demonstrated that pathological Tau and Amyloid-beta (Aβ) disrupt autophagy gene expression, independently. Other studies have shown that these pathological aggregates create a vicious cycle with oxidative stress.METHODS: In the current r

The Interplay of US and International Term Premiums: The Role of Uncertainty and Economic Conditions
We explore the determinants of term premiums and evaluate the influence of the US market on term premiums in seven developed countries. Our analysis shows that poor economic conditions and high uncertainty lead to increased term premiums. Further, our results highlight the importance of US economic conditions and uncertainty factors as well as the supply of US government bonds as key drivers of in
Clinical assessment and treatment of patients presenting with longstanding hip and groin pain in primary care: a survey study among physical therapists and general practitioners in Sweden
Abstract Background Methods of assessment, treatment and referral rates of patients presenting with longstanding hip and groin pain (LHGP) are not well documented. The aim of this study was to investigate assessment and treatment of patients with LHGP among general practitioners (GPs) and physical therapists (PTs) in primary care. Methods An anonymous web-based survey was developed specifically fo
Andean lakes : endangered by natural and anthropogenic threats
The Andes mountains extend north–south in a latitudinal gradient of 8500 km. Because of the great climatic variety and the peculiar north–south orographic distribution, lakes are highly diverse, including different lake origins and contrasting morphometries. We reviewed >700 ecological studies on Andean lakes to identify the main threats to these freshwater systems. The most important threats are
