From Witch Doctor to Modern Medicine: Searching the American Tropics for Potentially New Medicinal Plants
From Witch Doctor to Modern Medicine: Searching the American Tropics for Potentially New Medicinal Plants "And as there are discouvered new Regions, new King- doms and new Provinces by our Spaniards, so they have brought unto us new Medicines, and newe Remedies, wherewith they do cure many infirmities, which, if we did lacke them, would be incurible, and without any remedie ... for which cause I did pretend to treate, and to write of all things that they bring from our Indias, apperteyning to the Arte and Use of Medicine, and the remedie of hurtes and diseases that we doo suffer and endure ...". Nicholas Monardes [transl. John Frampton] "Joyfull Newes out of the New-found World" (1596) The search for potential new medicines from the Plant King- dom is not new. It has been carried on since man first became aware ot the variety ot ettects that plants had on his mind and body. It is still under way. But we now have many ad- vantages over man in all prior ages. We have millennia of experience behind us; a deeper understanding of what plants are and how they live; an intensity of modern technology to help us; and, what is more important than all of the other advantages, a determination to probe into the still virgin vegetal world for active compounds of promise for man’s existence. Today we follow several discreet paths in our search for "new" medicinal plants. Some modern programs - ambitious, technologically com- plex and potentially promising - have emphasized the random or semi-random screening of plants from all parts of the world for new organic compounds. -

For three years, we sampled second-growth woodlots and apple orchard-adjacent forest Canopy ecology sites from late March to early June every 7–10 days with paired sets of tri-colored pan traps in the canopy (20–25 m above ground) and understory (<1m). Roughly one fifthof the known New York state bee fauna were caught at each height, and 90 of 417 species overall, with many species shared across the strata. We found equal species richness, higher diversity, and a much higher proportion of female bees in the canopy compared to the understory. Female solitary, social, soil- and wood-nesting bees were all abundant in the canopy while soil- nesting and solitary bees of both sexes dominated the understory. -

Citizen Scientists Document Geographic Patterns in Pollinator Communities
Journal of Pollination Ecology, 23(10), 2018, pp 90-97 CITIZEN SCIENTISTS DOCUMENT GEOGRAPHIC PATTERNS IN POLLINATOR COMMUNITIES Alison J. Parker* and James D. Thomson University of Toronto, Department of Ecology and Evolutionary Biology, 25 Harbord Street, Toronto, Ontario M5S 3G5 Canada Abstract—It is widely recognized that plants are visited by a diverse community of pollinators that are highly variable in space and time, but biologists are often unable to investigate the pollinator climate across species’ entire ranges. To study the community of pollinators visiting the spring ephemerals Claytonia virginica and Claytonia caroliniana, we assembled a team of citizen scientists to monitor pollinator visitation to plants throughout the species’ ranges. Citizen scientists documented some interesting differences in pollinator communities; specifically, that western C. virginica and C. caroliniana populations are visited more often by the pollen specialist bee Andrena erigeniae and southern populations are visited more often by the bombyliid fly Bombylius major. Differences in pollinator communities throughout the plants’ range will have implications for the ecology and evolution of a plant species, including that differences may affect the male fitness of individual plants or the reproductive success of plant populations, or both. Keywords: citizen science, plant-pollinator interactions INTRODUCTION Looking for and documenting large-scale patterns in A rich history of research has explored the role of a pollinator communities requires a great deal of observational pollinator species in determining the reproductive success of a data. Studies are often limited to just one or a few plant plant, selecting for plant traits, and in some cases influencing populations (Herrera et al. -

Recommendation of Native Species for the Reforestation of Degraded Land Using Live Staking in Antioquia and Caldas’ Departments (Colombia)
UNIVERSITÀ DEGLI STUDI DI PADOVA Department of Land, Environment Agriculture and Forestry Second Cycle Degree (MSc) in Forest Science Recommendation of native species for the reforestation of degraded land using live staking in Antioquia and Caldas’ Departments (Colombia) Supervisor Prof. Lorenzo Marini Co-supervisor Prof. Jaime Polanía Vorenberg Submitted by Alicia Pardo Moy Student N. 1218558 2019/2020 Summary Although Colombia is one of the countries with the greatest biodiversity in the world, it has many degraded areas due to agricultural and mining practices that have been carried out in recent decades. The high Andean forests are especially vulnerable to this type of soil erosion. The corporate purpose of ‘Reforestadora El Guásimo S.A.S.’ is to use wood from its plantations, but it also follows the parameters of the Forest Stewardship Council (FSC). For this reason, it carries out reforestation activities and programs and, very particularly, it is interested in carrying out ecological restoration processes in some critical sites. The study area is located between 2000 and 2750 masl and is considered a low Andean humid forest (bmh-MB). The average annual precipitation rate is 2057 mm and the average temperature is around 11 ºC. The soil has a sandy loam texture with low pH, which limits the amount of nutrients it can absorb. FAO (2014) suggests that around 10 genera are enough for a proper restoration. After a bibliographic revision, the genera chosen were Alchornea, Billia, Ficus, Inga, Meriania, Miconia, Ocotea, Protium, Prunus, Psidium, Symplocos, Tibouchina, and Weinmannia. Two inventories from 2013 and 2019, helped to determine different biodiversity indexes to check the survival of different species and to suggest the adequate characteristics of the individuals for a successful vegetative stakes reforestation. -
Floristic Quality Assessment Report
FLORISTIC QUALITY ASSESSMENT IN INDIANA: THE CONCEPT, USE, AND DEVELOPMENT OF COEFFICIENTS OF CONSERVATISM Tulip poplar (Liriodendron tulipifera) the State tree of Indiana June 2004 Final Report for ARN A305-4-53 EPA Wetland Program Development Grant CD975586-01 Prepared by: Paul E. Rothrock, Ph.D. Taylor University Upland, IN 46989-1001 Introduction Since the early nineteenth century the Indiana landscape has undergone a massive transformation (Jackson 1997). In the pre-settlement period, Indiana was an almost unbroken blanket of forests, prairies, and wetlands. Much of the land was cleared, plowed, or drained for lumber, the raising of crops, and a range of urban and industrial activities. Indiana’s native biota is now restricted to relatively small and often isolated tracts across the State. This fragmentation and reduction of the State’s biological diversity has challenged Hoosiers to look carefully at how to monitor further changes within our remnant natural communities and how to effectively conserve and even restore many of these valuable places within our State. To meet this monitoring, conservation, and restoration challenge, one needs to develop a variety of appropriate analytical tools. Ideally these techniques should be simple to learn and apply, give consistent results between different observers, and be repeatable. Floristic Assessment, which includes metrics such as the Floristic Quality Index (FQI) and Mean C values, has gained wide acceptance among environmental scientists and decision-makers, land stewards, and restoration ecologists in Indiana’s neighboring states and regions: Illinois (Taft et al. 1997), Michigan (Herman et al. 1996), Missouri (Ladd 1996), and Wisconsin (Bernthal 2003) as well as northern Ohio (Andreas 1993) and southern Ontario (Oldham et al. -
