I'm a marine ecologist by trade specializing in marine mammals ;)

Thanks so much! That would be a great one to add one day!

Thanks!

Hi there, my apologies for the delay! I missed this comment. Here's a bit of info for you: Defining Heterogeneity within Landscape Ecology: Landscape heterogeneity in landscape ecology refers to the variety and spatial arrangement of different land cover types within a landscape. It can be further divided into two key components: Compositional Heterogeneity: This aspect focuses on the number and proportions of various land cover types within the landscape. It essentially describes what types of elements (e.g., forests, wetlands, urban areas) are present and in what quantities. Configurational Heterogeneity: This aspect delves into the complex spatial arrangement or pattern of these different land cover types. It describes how these elements are distributed, their shapes, sizes, and how they interact spatially. Correlation and Effects of Changing Composition and Configuration: Altering the composition and configuration of a landscape can have profound ecological consequences. Here are some potential effects: Biodiversity: Changing composition and configuration can impact species diversity. For example, increasing the proportion of a certain land cover type might favor species adapted to that habitat, while decreasing it could reduce their populations. Ecosystem Services: Modifications can affect the provision of ecosystem services such as pollination, water purification, and climate regulation. Connectivity: Changes can influence the connectivity of habitats, affecting species' ability to move and disperse, which can have implications for genetic diversity and resilience. Disturbance and Resilience: Alterations in configuration can influence how disturbances (e.g., wildfires) spread and how landscapes recover from such events. Example of a Shifting Mosaic: A shifting mosaic is a concept in landscape ecology that describes the dynamic and ever-changing nature of landscapes due to natural processes and disturbances. An example could be a forest ecosystem subject to periodic wildfires. In this scenario: The "mosaic" refers to the different patches or areas within the forest, which may consist of varying stages of growth and different species compositions. The "shifting" part highlights that these patches change over time as fires burn through the landscape. After a fire, a patch of mature forest might become a patch of young regenerating forest, creating a dynamic mosaic of forest patches at different stages of development.

Great idea Srijna! I will certainly put that one on the list!

Hi there, I don't specialize in molecular biology, but here's a good resource for topics in molecular bio - tinyurl.com/332c44ea

Great suggestion - thanks Sarah!

Thanks for watching!

Very cool - I have always wanted to go there! Apparently the Western Scheldt estuary is a bar built one!

@@lizferguson Oh yea I looked it up now, you are right! I always forget the Westerschelde is also the Rhine-Meuse-Scheldt delta area. I guess that comes with the heavy human-made infrastructure there to keep the cities and villages dry.

Of course - glad you enjoyed!

Thank you - glad it is useful!

Thanks!!!

Thank you so much for the comment - I'm glad to hear it is helpful and best of luck with your PhD!

Thanks so much!

Thanks Kasara!

I will aim to!

Thanks! And good suggestions!

Thanks - glad it is useful!

Glad it helped!

Thanks Jake! I will definitely look into it ;)
