In spite of this, they are among the most threatened ecosystems in the world. This study integrates three ecological approaches generally studied separately: climate change scenery, ecological niche and population dynamics of Oreomunnea mexicana (an endangered and relict species), to understand how environmental change affects the population structure in the cloud forest that will allow its conservation. -
(Juglandaceae) in the Early Miocene of Panama
CHAPTER 7 FRUITS OF OREOMUNNEA (JUGLANDACEAE) IN THE EARLY MIOCENE OF PANAMA Fabiany Herrera, Steven R. Manchester,* Rebecca Koll, and Carlos Jaramillo ABSTRACT Permineralized fruits of Juglandaceae have been recovered from the Early Miocene Cucaracha Formation exposed in excavations of the Panama Canal. Transverse sections and peels reveal that the nuts are subdivided into eight chambers at the base, and the nutshell and septa are composed mainly of fibers. Together, these features are found only in the Neotropical juglandaceous clade composed of extant Alfaroa Standl. and Oreomunnea Oerst. Based on the small nut size and rela- tively thin wall and septa, these nuts are assigned to Oreomunnea, which is distinguished from extant Alfaroa by its winged fruits adapted for wind dispersal. A. Graham first reported pollen grains of the Alfaroa/Oreomunnea type from the Miocene of Panama. The new fossil fruits of the Cucaracha Formation are the earliest macrofossil record of Oreomunnea, enhancing our under- standing of the phytogeographic history of Juglandaceae in Central America. If this newly de- scribed fossil species, O. grahamii Manch. & Herrera, grew in similar ecological settings to those of its modern counterparts, the fossils may be an indicator of the medium-high paleotopographic relief of Panama during the Early Miocene. Key words: Alfaroa, fossils, fruits, Juglandaceae, Miocene, Oreomunnea. The Juglandaceae have an excellent fossil rec- Neotropical genera Alfaroa Standl. and Oreo- ord in the Northern Hemisphere, well represented munnea Oerst. have mostly eluded detection in by pollen, leaves, wood, catkins, and fruits.

Ovrebo2 1 Department of Biology, Faculty of Natural Sciences, Universidad del Rosario. Bogota, 111221, Colombia. 2 Department of Biology, University of Central Oklahoma. Edmond, OK. USA. ABSTRACT Panamanian montane forests harbor a high diversity of fungi, particularly of ectomycorrhizal (ECM) fungi, however their taxonomy and diversity patterns remain for the most part unexplored. Here we present state of the art fungal taxonomy and diversity patterns at Fortuna Forest Reserve based on morphological and molecular identification of over 1,000 fruiting body collections of macromycetes made over a period of five years. We compare these new results with previously published work based on environmental sampling of Oreomunnea mexicana root tips. We compiled a preliminary list of species and report 22 new genera and 29 new fungal species for Panama. Based on fruiting body collection data we compare the species composition of ECM fungal communities associated with Oreomunnea stands across sites differing in soil fertility and amount of rainfall. We also examine the effect of a long-term nitrogen addition treatment on the fruiting body production of ECM fungi. Finally, we discuss the biogeographic importance of Panama collections which fill in the knowledge gap of ECM fungal records between Costa Rica and Colombia. -

Read Full License Page 1/23 Abstract This study aims to investigate the phylogenetic relationships within the Juglandaceae family based on the Internal Transcribed Spacer's primary sequence and secondary structures (ITS2). Comparative analysis of 51 Juglandaceae species was performed across most of the dened seven genera. The results showed that the ITS2 secondary structure's folding pattern was highly conserved and congruent with the eukaryote model. Firstly, Neighbor-joining (N.J.) analysis recognized two subfamilies: Platycaryoideae and Engelhardioideae. The Platycaryoideae included the Platycaryeae (Platycarya+ (Carya+ Annamocarya)) and Juglandeae (Juglans-(Cyclocarya + Pterocarya)). The Engelhardioideae composed the (Engelhardia+Oreomunnea+Alfaroa)). The Rhoiptelea genus was generally regarded as an outgroup when inferring the phylogeny of Juglandaceae. However, it is clustered into the Juglandaceae family and showed a close relationship with the Platycaryoideae subfamily. Secondly, the folded 3-helices and 4-helices secondary structure of ITS2 were founded in the Juglandaceae family. Therefore, these ITS2 structures could be used as formal evidence to analyze Juglandaceae's phylogeny relationship. -
CYCADACEAE Palm-Like Dioecious Plants, the Caudex Bulb
CYCADACEAE Palm-like dioecious plants, the caudex bulb-like, tuber like or columnar, simple or branched, few or several leaves borne from the apex; leaves spirally arranged, often a dense crown on the apex of the stem, coriaceous, pinnate or bipinnate, the leaflets usually linear or lanceolate, entire or dentate; inflo rescence borne at the apex of the caudex or lateral, cone-like, the pistillate eones broader than the staminate ones. Three genera native in Central America and about nine in the tropics of the world. Ceratozamia mexicana Brongn. is an attractive plant of Mexico and Guatemala that should be in cultivation. Dioon mejiae Standl. & L. Wms. Ceiba 1: 37. 1950. Teosinte, palma teosinte. The Indians of Olancho, Honduras, where the plant is native, boil and grind the large chestnut-like seeds and make of them a kind of tortilla of good flavor and agreeable to eat. The leaves are in demand for decorating altars and for funeral wreaths. Becoming widely distributed as an ornamental. The common name given for this plant is usually that applied to Euchlaena mexicana. Zamia loddigesii Miq. Tijdschr. Nat. Geschied. 10: 73. 1843. Camotillo, cocalito, teosinte, chacuhua. The large starchy roots are said to be used in poisoning rodents in Petén. There are reports of their use in criminal poisonings which may be or not based on fact. Standley reports that "It is stated, further, that if the root has been out of the ground three days, they cause death in three days; if dug ten days, they kill in ten days, and so on." The coastal Caribs have used the roots as food, after cooking. -

It was a dream into reality! The collaboration with the German counterpart started at the beginning of my academic career and I never imagine that this will be continued to bring this research that summarizes the efforts of many researchers that worked hardly in the overwhelming and incredible biodiverse tropics. -
