Two-leaf nightshade, Solanum diphyllum, is a member of the Solanaceae or potato family. It is native to Mexico southwards to Costa Rica. It has escaped cultivation in Florida and grows as far north as Duval County and from Volusia County south to Miami-Dade County. A “bird-dispersed” volunteer, it occurs in urban and conservation areas and on disturbed land. The plants produce abundant berries with many many small seeds. This new 5-page publication of the UF/IFAS Environmental Horticulture Department is primarily intended for Florida gardeners, landscapers, and land managers, and it contains information on identification, flowering, fruiting, and management recommendations for this widely occurring plant. Written by Stephen H. Brown, Chris Marble, and Stephen F. Enloe.

Railroad vine is one of the most widely distributed beach plants in the world. The moving sand and salt spray make the beach environment a harsh one, and the plants that live there are specialized to colonize this environment. This new 7-page document, published by the UF/IFAS Environmental Horticulture Department, describes railroad vine’s leaves, flowers, fruit, planting and maintenance, and insect and disease problems. Written by Stephen H. Brown and Marc S. Frank.

What does the general public know about neonicotinoids used in ornamental horticulture and their effects on pollinators? The question is an important one given that home landscapes serve as pollinator habitat and can impact pollinator health. This 5-page fact sheet written by Hayk Khachatryan, Xuan Wei, and Alicia Rihn and published by the UF/IFAS Food and Resource Economics Department summarizes a survey addressing consumer knowledge about neonicotinoids and pollinator plants, as well as their interest in enhancing pollinator health. The survey is part of a larger research project aimed at incorporating pollinator conservation into the ornamental horticulture industry's sustainability initiatives.

Hurricane Toads

A close-up photo of one of the abovedescribed raisin-sized froglets seated on a dime. It fits easily within the area of the dime, leaving a substantial margin uncovered: a very small frog.

Eastern spadefoots are a common but largely unappreciated species of native toad in Florida. Following torrential rains they emerge from hiding and breed in shallow pools. In as little as 14 days, hordes of raisin-sized froglets emerge and hop away in all directions from the pond or puddle where they were born. Some of them find their way to yards and garages of suburban neighborhood homes. Other unlucky baby toads end up on roads, where they are smashed. This 5-page fact sheet written by Steve A. Johnson and Candace D. Fuhrmann and published by the UF/IFAS Department of Wildlife Ecology and Conservation outlines the unique biology of this species and explains how to identify eastern spadefoot tadpoles, young, and adults. It also includes a section on how you and your friends and family can help these interesting and attractive little creatures by engaging in citizen science.

Diagnostic Methods for the Comprehensive Health Assessment of the Long-Spined Sea Urchin, Diadema antillarum

Using a dissecting microscope to examine D. antillarum. This animal was to be necropsied, so spines were cut prior to the exam. If the procedure is planned as a nonlethal exam, the spines should not be damaged.

This 55-page document contains a wealth of information on the long-spined sea urchin, which is an important animal in coral reef ecosystems. The publication discusses diagnostic methods for Diadema antillarum and provides reporting forms for laboratory and diagnostic work.

Facts about Wildlife Diseases: Bats and Coronaviruses

Tripart infographic showing a silhouetted pig, three bats, and an unidentified animal but presumably a civet cat in a blue panel on the left. Inside the blue panel are arrows leading from the three bats to the pig above and the civet cat below. Another blue arrow points to a silhouetted human figure centered in the white space between the blue panel on the left and a purple panel on the right containing a single sillouetted man holding a pitchfork and two additional groups of people, some adults in business attire and four children holding hands. Three smaller purple arrows point from the central human figure in the whitespace to the people in the purple panel.
Bats benefit both natural ecosystems and people. Viruses that live in bats can harm people, but transmission of these pathogens from bats to humans can occur only when humans come too close to bats. Recently, misguided attempts to preserve human health have led to persecution of bats. In fact, however, what will keep people healthy is to protect bats and their habitat. This 4-page fact sheet written by Holly K. Ober and Samantha M. Wisely and published by the UF/IFAS Department of Wildlife Ecology and Conservation explains how protecting bat roosts can reduce the likelihood of future zoonotic disease pandemics while also increasing the natural pest reduction services bats provide as they consume insects that cause damage to agronomic crops as well as the mosquitoes that transmit diseases like Zika, dengue, malaria, and chikungunya. Finally, protecting bat roosts keeps bats safely distanced from people, whereas destroying their homes risks the health of both people and bats because it forces bats into closer proximity to people.

Yellow-Legged Hornet (suggested common name), Vespa velutina (Lepeletier 1836) (Insecta: Hymenoptera: Vespidae)

Close-up photo of Vespa velutina clinging to a flower and feeding on nectar.

The yellow-legged hornet, Vespa velutina (Lepeletier), is a pest of concern outside of its native range. Vespa velutina is native to Southeast Asia and has invaded several regions in Europe, first appearing in France in 2004. As a generalist predator, they are a pest of honey bees and a major concern to many beekeepers. Vespa velutina has not been intercepted in North America, but it is believed to have high invasion potential. This 5-page fact sheet written by Krystal Ashman, Oliver Keller, and Cameron Jack and published by the UF/IFAS Entomology and Nematology Department describes the hornet and explains its live cycle, biology, and some of its predatory strategies.

Asian Giant Hornet, Vespa mandarinia Smith (1852) (Insecta: Hymenoptera: Vespidae)

Close-up photo of a female Vesma Mandarina Smith, resting on a leaf, some tiny beads of water on its striking yellow head

Vespa mandarinia Smith, commonly called the Asian giant hornet, is the largest hornet in the world. Its size and distinctive markings make it easily distinguishable from other Asian hornet species. Not only is the wasp occasionally life-threatening to humans, it can decimate a number of insect colonies, most notably wild and farmed honey bees. Vespa mandarinia is native to Japan and occurs in several countries in Asia. The first Vespa madarinia hornet detected in the United States was in Washington State in 2019. This 5-page fact sheet written by Caitlin Gill, Cameron Jack, and Andrea Lucky and published by the UF/IFAS Entomology and Nematology Department describes the hornet, its biology, its predatory strategies, and its medical significance. The fact sheet also provides some strategies for management of this dangerous and destructive hornet.

Recruitment, the process by which small fish transition to older, larger life stages, is probably the most important process that regulates populations of fish, but it is complicated to understand. This 6-page fact sheet written by Edward V. Camp, Robert N. M. Ahrens, Angela B. Collins, and Kai Lorenzen and published by the UF/IFAS Program in Fisheries and Aquatic Sciences, School of Forest Resources and Conservation explains the recruitment process in fish populations and why recruitment is so important to fisheries science and management.
