Introduction
I am a dedicated Postdoctoral Researcher at the Helmholtz Centre for Environmental Research (UFZ) in Magdeburg, where my research focuses on the complex interactions between agricultural land use and stream ecosystems. With a strong foundation in data-driven approaches, I utilize advanced analytical techniques and geospatial tools to assess the impacts of land-use practices on aquatic environments.
Methods and techniques: Remote sensing, GIS, Statistical modelling

This repository contains a comprehensive implementation of the land use intensity index for stream ecosystems (LUIS), a spatially explicit and hydrologically informed framework for assessing diffuse agricultural pressures on freshwater ecosystems. Developed in Python and executed through a suite of Jupyter Notebooks, the code facilitates the quanti...
Mangrove forest canopy gaps occur in 35 countries across the global distribution of mangrove forests in some 110 countries. Yet, their spatial and temporal patterns and drivers of their formation and closure remain poorly understood. Here, we investigated whether gaps are distributed randomly, clustered, or dispersed over space and time in two show...
The dataset contains information on the status, sizes, and geographical range of canopy gaps in South Africa's largest mangrove forest stand at uMhlathuze, which accounts for 80% of the total mangrove coverage in the country, near Richards Bay. It also includes a smaller mangrove stand in Beachwood near Durban in the KwaZulu-Natal province. The dat...
Mangrove forests are located at the interface between land and sea in tropical and subtropical latitudes. They provide several valuable ecosystem services, including carbon sequestration, habitat for diverse fauna, coastal protection, and serving as a source of fuel and timber for coastal com-munities. However, the unique location of mangrove fores...
This study is the first ever to gather local mangrove scientists, forest managers and policy-makers world-wide to identify the future scientific curiosity-driven and managerial need-driven questions to which science, management, and/or governance needs an answer.
Forest gaps have been observed in tropical and sub-tropical mangrove ecosystems across the globe, including Panama, Papua New Guinea, the Dominican Republic, Australia, Florida, Malaysia, French Guiana and South Africa. However, no comprehensive survey of the global distribution of these gaps has been undertaken. Furthermore, the cause of gap forma...

I am trying to model a continuous outcome variable(non-integer, with excess zeros) by two independent variables.
I have seen that people have referred to the compound poisson gamma model( https://doi.org/10.1111/2041-210X.12122) as one of the possible models to deal with such a problem.
I'd like to get your opinion regarding to which statistical approach will you recommend solving this problem using R
Do you have any idea how to plot the prediction probabilities of such a model?
What is the funtion of C/N ratio or organic matter conent in determing the presence of a plant?
How to calculate hydroperiod using elevation measurements from a microtopgraphy?
How to determine the distribution and abundance of shrubs in a mangrove forest?
what is the role of Acrostichum aureum on the organic matter,C;N , and salinity of the mangrove sediment?
How to analyse organic matter structure of mangrove sediments?
how to sample and store sediment from mangrove forest?
Please how do i determine the C:N organic structure and content of a mangrove sediment?
