In this blog post, I share a step-by-step guide on how to use raster data from distance to the coast. I walk you through the steps I used using the North German Sea as an example. #Rstats #GeospatialAnalysis www.miriam-lerma.com/posts/2025-0...

Here are the steps I used for creating a bathymetric map in R. From where to download bathymetric data to how to read it and plot it in R. #Rstats #GeospatialAnalysis www.miriam-lerma.com/posts/2025-0...

There are numerous tools available for analyzing tracking data, here I share a curated collection of my blog entries that focus specifically on movement analysis. I’ve also included a brief list of related papers. #animalmovement #biologging #tracking www.miriam-lerma.com/posts/2024-1...

I’m currently involved in #seabirds at-sea monitoring program in Germany 🇩🇪, analyzing Digital Aerial Surveys #DAS I’m also involved in #tracking projects in Chile 🇨🇱 and Mexico 🇲🇽 If this was not confusing enough, I relocated to the UK 🇬🇧 and I am a freelancer for fieldwork and data analysis 😅☝️

When analyzing tracking data in R, you may want to explore the locations. R also offers interactive mapping features. In this post, I’ll walk you through the steps I used to create interactive maps using #tmap www.miriam-lerma.com/posts/2024-1... #rstats #GIS #tracking

I'm migrating all my old posts to BlueSky. For this project, we analyzed heavy metals (Cd, Pb, and Hg) in adult and chick Blue-footed boobies." #ornithology #seabirds #heavymetals Here is what we found -> Read the link for the abstract and publication link: www.miriam-lerma.com/publications...

On the most remote island in Mexico #revillagigedo, we studied the isotopic niche of red-footed and masked boobies. This is what we found: "Variations in inter‐specific and sex‐related niche partitioning in pelagic boobies during their annual cycle" t.co/ZPVFbxmvAt #seabirds 🇲🇽 #Mexico

For this project, we studied sexual segregation in foraging in relation to the breeding stage in masked boobies by simultaneously tracking incubating and chick-rearing birds. Abstract and link: www.miriam-lerma.com/publications... #seabirds #Chile

I'm migrating all my old posts from my publications to BlueSky. A great chance to start fresh! For this project back in Mexico, we analyzed Zn in Blue-footed boobies, comparing eggs, chicks, females, and males. Here are the abstract and the link: www.miriam-lerma.com/publications... #seabirds

When I was still living in Sinaloa, I followed the reproduction and assessed the nutritional status of blue-footed boobies, want to see what we found? #seabirds #research #tropical See our publication : t.co/pQ9IKHbmii

My new blog post includes calculating the distance between points and making a map to show relevant distances using R. #rstats #ggplot2 Check it out at: www.miriam-lerma.com/posts/2024-0...

When studying movement of animals we can have some gaps. In my new blogpost, I share a function I created in R to interpolate the data to fill those gaps. I also share link to other packages that also do the job. Check the post here: www.miriam-lerma.com/posts/2024-0... #rstats #seabirds

Certain locations need to be excluded when conducting spatial analyses, such as those near the nests. In this blog post, I share how I create a buffer in R #rstats to remove these locations. t.co/2YC6tkI3un

When tracking animals, there may be times when they enter areas with no reception. In this post, I’ll walk you through the steps I used to determine whether trips are complete or incomplete. lnkd.in/eAgz9rQE

How far is it? When studying animal movement, we often need to calculate the distance an animal covers from one location to another. In this post, I share the code I use to calculate the distance between consecutive locations. #seabirds #rstat #movementecology lnkd.in/eBC9vJwF
