“…At the population level, H E from CAOB and PION were higher than H O , and F IS was significant (CAOB F IS =0.097; PION F IS =0.163), which suggest a higher average rate of inbreeding. In contrast, the Dvorak et al (2005), with isozymes for populations of this variety from Belize and Guatemala (F IS =0.011). Another interesting result is the average number of alleles per locus, which was lower for both populations (CAOB, four alleles and PION, three alleles) than the average reported for other pine species, such as P. resinosa (nine alleles, (Boys et al 2005)), P. radiata (six alleles, (Smith and Devey 1994); seven alleles, (Karhu et al 2005)), Pinus oocarpa, Pinus patula, and Pinus tecunumanii (five alleles, (Dvorak et al 2009)), and similar to other populations of P. caribaea var.…”

“…Only a single population was known from Mexico formerly, occurring in the Ejido of Caobas in the locality known as "Jaguactal" in the state of Quintana Roo. According to different authors, this population consists of 150 (Macario et al 1998; this study) to 1,000 (Dvorak et al 2005) reproductive trees and is considered endangered (NOM-059-2001). In this study, we report a new population located on the southern boundary of the states of Campeche and Quintana Roo.…”

“…Therefore, the PION population has suffered a great loss of alleles due to the effect of genetic drift, while the CAOB population has experienced a reduction in both census and effective sizes. Dvorak et al (2005) offered the hypothesis that P. caribaea var. hondurensis populations were distributed more continuously in the past.…”

“…(Caribbean pine) is a tropical species with the southernmost and lowest elevation distribution of American pines (from 1 to 1000 m; Farjon and Styles 1997). It is represented by some large and continuous populations (Belize, Nicaragua, Honduras) and several that are restricted and fragmented (Belize, Guatemala, and Mexico; Dvorak et al 2005). Only a single population was known from Mexico formerly, occurring in the Ejido of Caobas in the locality known as "Jaguactal" in the state of Quintana Roo.…”

“…Recently, Dvorak et al (2005) used a predictive climatic model to propose that P. caribaea var. hondurensis had a larger distribution in the past (7,000-8,000 years BC), and today, it should occur along the east coast of Yucatan, as far north as Puerto Juarez, Quintana Roo.…”

Abstract• Introduction The recognition of endangered species takes into account geographic isolation and small size of populations, as is the case of two populations of Pinus caribaea var. hondurensis distributed in México.• Materials and methods This study evaluates the genetic variation within and among Mexican populations of P. caribaea var. hondurensis to make inferences on the historical dynamics of the populations by screening a total of 69 trees with six nuclear microsatellites.• Results The results indicate intermediate levels of genetic variation in both populations (H E = 0.465). The level of inbreeding was significant for both populations (Caobas F IS = 0.097; Pioneros F IS = 0.163), but the effective population size was higher in the Pioneros population (N e = 868) compared to Caobas (N e = 402). Average genetic differentiation was low (R ST = 0.033) and historical migration rate was relatively high (M = 13.2).• Discussion These results, together with the analysis of bottlenecks, provide us evidence of historical events of contraction of the population size, which probably occurred between 8,100 and 35,000 years ago. We propose conservation strategies for the emergent recovery of these remaining native forest patches.

We focus on pre-Columbian agricultural regimes in the Maya Lowlands, using new datasets of archaeological wood charcoal, seeds, phytoliths, and starch grains; biological properties of plants; and contemporary Indigenous practices. We address inherited models of agriculture in the lowlands: the limitations of the environment (finding more affordances than anticipated by earlier models); the homogeneity of agricultural strategies (finding more heterogeneity of strategies across the lowlands than a single rigid template); the centrality of maize in agriculture (finding more reliance on root crops and tree crops than historically documented); the focus on the milpa system as food base (finding more agroforestry, homegardening, horticulture, and wild resource management than previously documented); the dominance of swidden strategies in agricultural practices (finding more diverse practices than accounted for in most models); and the foregrounding of maize crop failure in collapse models (finding more evidence of resilience and sustainable agricultural practices than predicted).
