The local extinction of Cedrus atlantica in the Iberian Peninsula could have been completed due to biological interaction
Description
This data set is used to explore the possibility that Cedrus atlantica (Endl.) Carrière and Pinus nigra Arnold could have interacted in the past, mutually excluding each other in the areas with suitable conditions for both species and, where, ultimately, the one that was most competitive would remain. The species show very well differenciated niches and a distribution of their habitats segregated by continents (P. nigra in Europe and C. atlantica in Africa), which responds to differences in climatic affinities. However, the contact of their distributions in bordering areas suggests that C. atlantica maintained its presence in the Iberian Peninsula until recent times, and that P. nigra could have displaced it due to its higher prevalence on the continent.
Methods
Species
Cedrus atlantica observations made directly in the field, in Morocco, have been used; and by recognition of the species by photo interpretation, in Algeria (n = 211).
Pinus nigra subsp. salzmannii (Dunal) Franco, the subspecies contemplated in this study, is limited to the Western Mediterranean. For the analysis of this work, 250 localities were randomly selected, at the working resolution (30 arc seconds), from the database of the Global Biodiversity Information Facility (GBIF, 2022). Redundant observations at working resolution were eliminated (n = 231).
Variables
Niche predictors were selected from the WorldClim 1.4 portal (1960-1990 series for the present). Four climatic variables were the ones that best fit the distribution models of C. atlantica prepared with MaxEnt:
- Minimum temperature of the coldest month (bio6; °C);
- Temperature annual range (bio7; °C);
- Mean temperature of the wettest quarter (bio8, °C);
- Precipitation of the driest month (bio14, mm).
