In the Company One Botanist’s Humbling Encounters with Ancient Dioons ofof GiantsGiants Article and photos (unless otherwise indicated) by Jody Haynes 1,400 years prior! This population occurs in tropical oak forest alongside a small stream; such a setting is quite common for many of the 30+ populations of this species in Honduras. There were no cones evident, but seedlings were present. Due to its remoteness and relative inaccessibility, this population—and the giants therein— is almost certainly not threatened. During the HN03 expedition, Mark and I visited more than 20 populations of Dioon mejiae, documented at least ten more, and elevated the conservation status of this species to Not Threatened from previous assessments suggesting that it was Rare (Lucas & Synge, 1978) or Vulnerable (Mace et al., 1992; Walter & Gillett, 1998). We also revised the estimate of the total number of wild plants, increasing it 120-fold from the previous estimate of 5,000 (Osborne, 1995) to no less than 600,000 mature plants spread across 10,000 ha in northern Olancho and eastern Yoro (Haynes & Bonta, 2003; Haynes & Bonta, In press). Dioon spinulosum—The popula- tion of this species that we visited in northern Oaxaca is approximately 120 km from the type locality. The plants were growing on a karst (limestone) mogote rising up out of the surrounding farm fields (Fig. 2). Many large and hundreds of medium-sized and juvenile plants were growing on this mogote. In one area, female cones and seedlings were abundant, where- as cones and seedlings were Fig. 1. The author is dwarfed by a giant Dioon mejiae in Olancho, Honduras essentially absent in another (photo by Mark Bonta). -

Mexico's Biocultural Diversity in Peril
SPECIAL ARTICLE Mexico’s Biocultural Diversity in Peril Omar Vidal1* & Richard C. Brusca2 1. Bosque de Granados 141, Col. Bosques de las Lomas, Ciudad de México 11700, México; [email protected] 2. Department of Ecology & Evolutionary Biology, University of Arizona, United States of America; [email protected] * Correspondence Recibido 16-XII-2019. Corregido 26-II-2020. Aceptado 27-III-2020. ABSTRACT. Introduction: Places with high species diversity have high linguistic diversity, whereas areas with low species diversity tend to have low linguistic diversity. Objective: To characterize the intriguing rela- tionship between biological and cultural diversity, a correlation that has been discussed at a global scale, but here tested for the first time in Mexico. Methods: We compiled exhaustive databases on both endangered spe- cies and endangered languages, and reviewed available literature on Mexico’s biocultural diversity with a focus on endangered and critically endangered species and languages. Results: With 364 living languages, Mexico is the world’s fifth most linguistically diverse country, but 64 of these languages are facing a very high risk of disappearance and 13 have already disappeared. Mexico is also the fourth most biologically diverse country, but 1 213 species of its flora and fauna are threatened with extinction and at least 127 species were recently extinct. Conclusions: Indigenous peoples are custodians of much of the world’s biocultural diversity. As the world grows less linguistically and culturally diverse, it is also becoming less biologically diverse. Mexico’s biological and linguistic diversity show strong geographic overlap, with the states of Oaxaca, Chiapas, Veracruz, Guerrero, and Michoacán harboring most species and most languages. -
Life History, Population Dynamics and Conservation Status of Oldenburgia Grandis (Asteraceae), an Endemic of the Eastern Cape of South Africa
The conservation, ecology, and distribution of the Critically Endangered Encephalartos latifrons Lehm. A thesis submitted in fulfilment of the requirements for the degree of DOCTOR OF PHILOSOPHY (SCIENCE) of RHODES UNIVERSITY by CARIN SWART Department of Botany March 2019 ABSTRACT Cycads have attracted global attention both as horticulturally interesting and often valuable plants; but also as some of the most threatened organisms on the planet. In this thesis I investigate the conservation management, biology, reproductive ecology and distribution of Encephalartos latifrons populations in the wild and draw out conclusions on how best to conserve global cycad biodiversity. I also employ computer- modelling techniques in some of the chapters of this thesis to demonstrate how to improve conservation outcomes for E. latifrons and endangered species in general, where information on the distribution, biology and habitat requirements of such species are inherently limited, often precluding robust conservation decision-making. In Chapter 1 of this thesis I introduce the concept of extinction debt and elucidate the importance of in situ cycad conservation. I explain how the concept of extinction debt relates to single species, as well as give details on the mechanisms causing extinction debt in cycad populations. I introduce the six extinction trajectory threshold model and how this relates to extinction debt in cycads. I discuss the vulnerability of cycads to extinction and give an overview of biodiversity policy in South Africa. I expand on how national and global policies contribute to cycad conservation and present various global initiatives that support threatened species conservation. I conclude Chapter 1 by explaining how computer-based models can assist conservation decision-making for rare, threatened, and endangered species in the face of uncertainty. -
