Benefits of Primary Care – Sports Medicine and Physical Therapy – Lifestyle Medicine

5 Benefits of Primary Care

In an increasingly complex medical world, having one doctor who knows your health history has become highly important.

Researchers at the journal Health Affairs found that patients who have a primary care provider benefit from better management of chronic diseases, lower overall health-care costs and a higher level of satisfaction with their care…

What is the Difference Between Sports Medicine and Physical Therapy?

Sports medicine and physical therapy are frequently confused for being the same thing. Understandably so since both focus on healing injuries of the muscles and bones. However, sports medicine and physical therapy have distinct differences. … A physical therapist does not need to attend medical school…

Schools Push Lifestyle Medicine to Boost Chronic-Disease Prevention

For all that medical students, residents and physicians learn or know about advances in pharmaceuticals, diagnostics and precision medicine that can improve patient outcomes, it is what happens in patients’ lives where they live, work and play that too often gets passed over—across the medical educational continuum. That is the case even though lifestyle choices can have the biggest impact on prevention and management of chronic diseases such as hypertension and diabetes…

Lifestyle Medicine: Treating the Causes of Disease

If doctors can eliminate some of our leading killers by treating the underlying causes of chronic disease better than nearly any other medical intervention, why don’t more doctors do it?

By treating the root causes of diseases with plants not pills, we can also avoid the adverse side effects of prescription drugs that kill more than 100,000 Americans every year, making them a leading cause of death…

 

How Does Smoking Damage Your Skin? – Marijuana and Your Skin

When someone mentions the toll smoking takes on your skin, what is the first thing that comes to mind? Most of us probably think of wrinkles, and with good reason. Some of the toxins in cigarette smoke damage collagen and elastin, which are fibrous components of skin that keep it firm and supple. This damage speeds up skin aging, making smokers more prone to wrinkles on their face and body…

White stork modelling Updated for 2026

Understanding lifetime tracks and fitness of long distance avian migrants. This is the title of our DFG-funded German-Israeli Project Cooperation and it is also our quest for several years. Within this project, we aim to explore how movement, survival and reproduction reflect an optimal response to the environment. Evidence is drawn from both theoretical and empirical analyses. Migrants like white storks are particularly interesting for studying these questions as they move large distances and may experience different environmental conditions in different parts of the world with more or less strong impacts on their fitness (carry-over effects). Small-scale movement and behavior and their impact on local population dynamics are equally interesting. Latest technologies allow us unprecedented insights into the life of animals. For example, ultra-light GPS tags allow tracking individuals with very high temporal resolution and over several years, and acceleration measurements allow classifying behavior from distinct acceleration signals. These data together with careful monitoring provide the means for better understanding movement phenomena and their consequences for population dynamics and fitness. Juni11 103 Mit_Sender

My main focus within the project are developing behavior-based models for different life-cycle stages (e.g. breeding, migrating, wintering) as well as annual-cycle models that allow studying carry-over effects on individual fitness and population dynamics. Thereby, optimality is an important topic. From evolutionary perspective, fitness-maximizing, optimal behavioral strategies should evolve, determining for example when an individual should start reproducing or start migrating within the annual cycle. On finer temporal and spatial resolution, optimal foraging strategies should evolve which are the focus of our study ‚Individual-based modeling of resource competition to predict density-dependent population dynamics: a case study with white storks‘ (Zurell et al.). Here, we aimed to better understand how density-dependent demographic rates may evolve from home range behavior. To this end, we built an individual-based model for foraging white storks that incorporates both physiology and behavior. We expected that the form of density dependence may differ between different home range behaviors. To our surprise, we also found that it may differ strongly between landscapes with the same degree of fragmentation and the same overall resource availability. This phenomenon is strongly affected by the behavioral trade-offs and by imperfect detection of resources. Thereby, simulated patterns corresponded surprisingly well to empirical patterns although the model was not calibrated. For predicting population or even community dynamics under changing environmental conditions, it seems crucial to better understand these interactive effects of behavior and local environment.

We heartily invite you to play around with the model code (available at http://www.wsl.ch/info/mitarbeitende/zurell/downloads_EN) and adapt it to your needs. As you will see, the model also allows exploring additional aspects of movement ecology, for example studying movement paths or density-dependent home range structures in more detail.
