Solving the stochastic dynamics of population growth

Ecology and Evolution, 2023
Population growth is a fundamental process in ecology and evolution. The population size dynamics during growth are often described by deterministic equations derived from kinetic models. Here, we simulate several population growth models and compare the

A LEAP Forward in Wildlife Conservation: A Standardized Framework to Determine Mortality Causes in Large GPS-Tagged Birds. [PDF]

Ecol Evol
A novel framework for determining the causes of mortality of large GPS‐tagged birds, the LIFE EUROKITE Assessment Protocol (LEAP), was developed. LEAP integrates GPS tracking data, site investigation, and necropsy to derive mortality causes and a corresponding certainty score. Two case studies demonstrated improvements in mortality assessments compared

Agricultural inputs unevenly boost crop yields but consistently reduce biodiversity on Mount Kilimanjaro

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
Crop productivity on Mount Kilimanjaro is shaped by interactions among climate, human capital and biodiversity. Labour capital strongly increased crop yields, whereas physical capital, particularly agrochemical inputs, reduced biodiversity without increasing yields.

Stomatal Decoupling From Photosynthesis Under High Temperatures Is Consistent With Stomatal Optimisation

Global Change Biology, Volume 32, Issue 7, July 2026.
Many leaf gas exchange models predict that photosynthesis and stomatal conductance are tightly coupled and respond in parallel to changing environmental conditions. However, experiments show that when temperatures increase beyond the thermal optimum of photosynthesis, stomatal conductance may continue to rise while photosynthesis declines, facilitating

Effects of drought on carbonyl sulfide exchange in four plant species

Plant Stress
The trace gas carbonyl sulfide (COS) is used for estimating gross primary productivity at ecosystem level (GPP), as the net CO₂ flux is confounded by ecosystem respiration.

Pioneer of Medical Mycology: In Memory of Prof. Friedrich Staib, MD, DVM

Mycoses, Volume 69, Issue 7, July 2026.
ABSTRACT At the beginning of Friedrich Staib's academic career in the 1950s, medical mycology was a young discipline in Germany. He studied veterinary and human medicine, earning two doctorates. Initially fascinated by the changes in intestinal flora caused by the newly emerging broad‐spectrum antibacterials, i.e., the selection of fungi.
