Polk Small Farms: New Environment Publications, November 2013

November's Environmental publications include two policy fact sheets – on carbon stores as an ecosystem service, another explaining cost-benefit analysis as a tool for environmental decisionmaking. Jiri Hulcr's fact sheet describes the biology and spread of the coffee berry borer and why that's important for coffee consumers. I've also included a fact sheet explaining ball moss, Spanish moss, and lichens from lawn & garden.

Environment
	Stewardship Ecosystem Services Study: Carbon Stores on Florida Forest Stewardship Program Lands Nonindustrial private forestlands in Florida provide many environmental benefits, or ecosystem services. Ecosystem services are benefits from nature that are directly enjoyed, consumed, or used by humans, such as water quality improvement or protection, recreation, biodiversity, and even timber. Another benefit from forests that is gaining interest is their ability to store carbon through the photosynthetic capture of carbon dioxide, a greenhouse gas, in tree, plant, and soil biomass. The carbon dioxide that is stored over the life of a forest, called carbon stocks, is not only important for mitigating greenhouse gas contributions to climate change, but it can also be valued in several markets and incorporated into environmental policy instruments. This 5-page fact sheet was written by Nilesh Timilsina, Francisco J. Escobedo, Alison E. Adams, and Sonia Delphin, and published by the UF Department of School of Forest Resources and Conservation, October 2013. http://edis.ifas.ufl.edu/fr384
	The Use of Cost-Benefit Analysis in Environmental Policy When analyzing environmental problems, economists consider both the benefits and costs of actions. If benefits exceed costs then economic theory supports that action. For example, if the total benefits of conserving land exceed the costs then cost-benefit analysis would support conservation of the land. However, great care must be taken to accurately identify and quantify benefits and costs to determine whether an action is cost-benefit justified. Stakeholders may have an incentive to overstate costs or benefits, in order to influence decision-making. This 5-page fact sheet was written by Elizabeth F. Pienaar, and published by the UF Department of Wildlife Ecology and Conservation, September 2013. http://edis.ifas.ufl.edu/uw383
	Why is your cup of coffee so expensive? Because of a tiny bark beetle! Sometimes an insect pest attacking crops in places as far away as Indonesia or Ethiopia can be very important to us here in Florida. One such insect is the coffee berry borer, Hypothenemus hampei Ferrari (Coleoptera: Curculionidae: Scolytinae), a tiny (1.5 mm) bark beetle that originated in the highlands of central Africa. It would probably remain one of the many inconspicuous little beetles in the tropics, if not for the choice of its host: seeds of several Coffea species.

Ecosystems and Species
		*Eastern Bloodsucking Conenose, Triatoma sanguisuga* (LeConte) (Hemiptera: Reduviidae: Triatominae)** The eastern bloodsucking conenose belongs to the subfamily Triatominae, known as the kissing bugs. Despite their affectionate vernacular name, they are particularly threatening "assassin bugs" who require blood meals to survive and reproduce. They are a known vector of American trypanosomiasis (or Chagas Disease) in South America, a debilitating illness caused by the parasite Trypanosoma cruzi. This disease is a problem in South and Central America and has been detected in the United States, but has not been found in Florida. This 4-page fact sheet was written by John L. Capinera, and published by the UF Department of Entomology and Nematology, November 2013. http://edis.ifas.ufl.edu/in1018
		*Green orchid bee Euglossa dilemma* Friese (Insecta: Hymenoptera: Apidae)** Green orchid bees are a quite conspicuous and charismatic species. This is mostly due to their large size and bright metallic-green coloration. They are very fast and agile flyers, and can be seen quickly darting from flower to flower separated by long periods of hovering. Male orchid bees collect fragrant volatile compounds from their environment and present them to females by fanning their wings and "spray ventilating" their bouquet for the inspection of prospective mates. In Florida, male green orchid bees are attracted to chemicals produced by certain wood-rot fungi, decomposing vegetation, perfume flowers, and certain essential oils such as clove and cinnamon oil. Male green orchid bees can be quickly and easily attracted and observed by soaking a small piece of paper with clove oil and placing it outside.

	*Identification and Control of Coral Ardisia (Ardisia crenata): A Potentially Poisonous Plant.* Coral ardisia, also known as coral berry, spice berry, and scratchthroat, was introduced to Florida in the early 1900′s for ornamental purposes. Since then, it has escaped cultivation, and it is found in hardwood hammocks and other moist, natural-wooded areas and grazing lands. Although there is no published literature supporting the theory that coral ardisia is toxic, it is suspected that the berries and/or foliage are poisonous to livestock, pets, and humans. This 3-page fact sheet was written by B. A. Sellers, Sarah Lancaster, K. A. Langeland, J.A. Ferrell, Michael Meisenberg, and J. Walter, and published by the UF Department of Agronomy, November 2013. http://edis.ifas.ufl.edu/ag281
		Ladybird beetles – recent immigrants to Florida (Insecta: Coleoptera: Coccinellidae) Since the publication of the Florida beetles checklist, a few ladybird beetles have become established in the state, some well-known and extensively documented and some little noticed and previously unreported. It is these latter species that are covered in this publication. All of the listed species are represented by voucher specimens in the Florida State Collection of Arthropods. Species previously known from Florida are reported by Frank and Mizell (2012) with emphasis on natural history. This 5-page fact sheet was written by Michael C. Thomas and Orland J. Blanchard, Jr., and published by the UF Department of Entomology and Nematology, October 2013. http://edis.ifas.ufl.edu/in1012
		Spanish Moss, Ball Moss, and Lichens – Harmless Epiphytes Epiphytes are "air" plants that survive on moisture and nutrients in the atmosphere. Several epiphytic plants, like Spanish moss, ball moss, and lichen, are common to the Florida landscape and southeast United States. People unfamiliar with epiphytes sometimes worry that they may cause injuries to the plants they perch in. Epiphytes do attach themselves to plants, but they do not harm the plants, unlike mistletoe, a plant parasite. Without soil as a source of nutrients, epiphytic plants have evolved the capacity to obtain minerals dissolved in water that flows across leaves and down branches.

	*Woolly oak aphids Stegophylla brevirostris* Quednau and Diphyllaphis microtrema Quednau (Insecta: Hemiptera: Aphididae)** Woolly oak aphids are conspicuous pests on oak, because they are covered with large amounts of flocculent wax. Two genera of woolly oak aphids occur in Florida, each including one known native Florida species. One species, Stegophylla brevirostris Quednau, is common, and the other, Diphyllaphis microtrema Quednau, is rare. This 3-page fact sheet was written by Susan E. Halbert, and published by the UF Department of Entomology and Nematology, October 2013. http://edis.ifas.ufl.edu/in1011
