Knowledge on species’ natural history, like observations of predator-prey interactions, help to understand the width of food webs and ecological niches. However, collating (un)published natural history information can be challenging, especially in this age of high scientific output, and even more so for geographically widespread and common species....
Article
The popularity of the Common Green Iguana (Iguana iguana) as a pet has contributed to its global occurrence as an invasive alien species. Early detection and control of alien I. iguana populations is necessary to prevent the need for large and financially demanding eradication actions. Here, we first collated information from digital footage and in...

Genetic data are a crucial and exponentially growing resource across all biological sciences, yet curated databases are scarce. the widespread occurrence of sequence and (meta)data errors in public repositories calls for comprehensive improvements of curation protocols leading to robust research and downstream analyses. We collated and curated all...
Article
The negative impacts of international wildlife trafficking are well known, and such negative impacts can be even more pronounced for insular species. This dynamic market needs close monitoring, and when novel species appear in the commercial trade, relevant authorities should be able to react to reduce negative impacts on wild populations. Here we...

Quantifying intraspecific variation in heat tolerance is critical to understand how species respond to climate change. In a previous study, we recorded variability in critical thermal maxima (CTmax) by 3 °C among populations of small Iberian lizard species, which could substantially influence predictions of climate-driven activity restriction. Here...

Question
Dear all,
I am looking for a commonly used Mammalia nomenclature resource/database/catalog. Preferably an online resource that is continuously updated. Similar to Frost (Amphibia) or the HBW (Aves).
I found the Mammal Diversity Database (https://mammaldiversity.org), however as I'm not a mammologist I wanted to make sure that I'm not missing other resources that are commonly used.
Thanks in advance.
Question
We have sighting transect data from animals in a natural population collected from two years and want to statistically compare these to assess increase/decrease in sightings/population size/etc. It concerns many transects that were repeatedly visited.
What different technique are out there to do this?
Two examples that we are already looking at are 1) population size estimate comparisons through DISTANCE, 2) ANCOVA tests.
Thanks, Matthijs
