Pollination of Two Species of Ferocactus: Interactions Between Cactus-Specialist Bees and Their Host Plants
Functional Blackwell Publishing, Ltd. Ecology 2005 Pollination of two species of Ferocactus: interactions 19, 727–734 between cactus-specialist bees and their host plants M. E. MCINTOSH Department of Ecology and Evolutionary Biology, 1041 E. Lowell Street; BioSciences West, Room 310, University of Arizona, Tucson, AZ 85721, USA Summary 1. Resolving the controversy over the prevalence of generalization in plant–pollinator interactions requires field studies characterizing the pollination effectiveness of all a plant’s floral visitors. Herein, the pollination effectiveness of all visitors to two species of barrel cactus (Ferocactus) was quantified. 2. Flowers of both species were pollinated almost exclusively by cactus-specialist bees: 99% (F. cylindraceus (Engelm.) Orcutt) and 94% (F. wislizeni (Engelm.) Britt. and Rose) of all seeds produced in this study resulted from cactus bee visits. 3. For F. cylindraceus, the cactus-specialist Diadasia rinconis was the most abundant visitor. For F. wislizeni, three cactus-specialists (including D. rinconis) plus generalists in the family Halictidae (which did not act as pollinators) each accounted for a quarter of all visits. 4. Diadasia rinconis visits to F. wislizeni flowers were more effective (per-visit) than visits by the other two cactus-specialists. 5. Pollen-collecting and nectar-collecting visits were equally effective. Nectar-collecting visits were the most abundant. 6. Apart from the non-pollinating halictids, floral visitors surprisingly did not include commonly co-occurring generalist bees. 7. These data suggest that, just as apparently specialized flowers may be visited by a diverse assemblage of generalists, so apparently generalized flowers may be visited predominantly by specialists, and that these specialists may perform virtually all of the pollination. -
Roadrunner Fact Sheet
Roadrunner Fact Sheet Common Name: Roadrunner Scientific Name: Geococcyx Californianus & Geococcyx Velox Wild Status: Not Threatened Habitat: Arid dessert and shrub Country: United States, Mexico, and Central America Shelter: These birds nest 1-3 meters off the ground in low trees, shrubs, or cactus Life Span: 8 years Size: 2 feet in length; 8-15 ounces Details The genus Geococcyx consists of two species of bird: the greater roadrunner and the lesser roadrunner. They live in the arid climates of Southwestern United States, Mexico, and Central America. Though these birds can fly, they spend most of their time running from shrub to shrub. Roadrunners spend the entirety of their day hunting prey and dodging predators. It's a tough life out there in the wild! These birds eat insects, small reptiles and mammals, arachnids, snails, other birds, eggs, fruit, and seeds. One thing that these birds do not have to worry about is drinking water. They intake enough moisture through their diet and are able to secrete any excess salt build-up through glands in their eyes. This adaptation is common in sea birds as their main source of hydration is the ocean. The fact that roadrunners have adapted this trait as well goes to show how well they are suited for their environment. A roadrunner will mate for life and will travel in pairs, guarding their territory from other roadrunners. When taking care of the nest, both male and female take turns incubating eggs and caring for their young. The young will leave the nest after a couple weeks and will then learn foraging techniques for a few days until they are left to fend for themselves. -

Succulent Container Gardening 101
SUCCULENT CONTAINER GARDENING 101 MATERIALS—What you need! Container-- Be creative! Small piece of coco fiber, paper towel, or landscaper’s cloth to cover the drainage hole Expanded shale, or gravel for drainage Succulent/cactus soil Chopstick, bbq skewer, spoon, a small brush and other utensils for hard to reach areas Plants: Succulents, cacti, or sedum Optional: o Decorative gravel, stones or sand to achieve that finished look! o Charcoal used to keep containers with no drainage hole sweet and fresh. CARING FOR SUCCULENTS—True love! Soil: Succulents and cacti thrive in well draining, porous soils. Gravel or expanded shale can be added to the bottom of the container to help increase drainage. A basic, sandy potting soil mixed with vermiculite makes a great succulent mix! Light: Succulents do very well in bright, indirect light-- most succulents will burn in direct sunlight. Although there are types of cacti that, in their natural environment thrive in full sun, we are mostly dealing with artificial growing conditions; therefore the plants need some protection. Succulents and cacti grow well in a variety of places; a covered porch or patio, in a bright room, or in the shade of other plants. Water: There are a couple of basics when it comes to watering succulents. 1. Never let the container sit in a saucer of water. If your container does not have a drainage hole, you will need to water less. 2. Never water a container that does not feel dry (your finger is a great tool when testing moisture!). As a general rule, water once a week in the summer, or in warm conditions. -

Photo: Robert Sivinski Petition Submitted to the U.S. Secretary of the Interior, Acting through the U.S. Fish and Wildlife Service Petitioner: WildEarth Guardians Address correspondence to: Taylor Jones [email protected] (720) 443-2615 May 29, 2020 INTRODUCTION WildEarth Guardians (Guardians) respectfully requests that the Secretary of the Interior, acting through the U.S. Fish and Wildlife Service (Service) list Clover’s cactus (Sclerocactus cloverae) as “threatened” or “endangered” under the U.S. Endangered Species Act (ESA) (16 U.S.C. §§ 1531- 1544). Guardians also requests that the Service designate critical habitat for the species concurrent with listing. ENDANGERED SPECIES ACT AND IMPLEMENTING REGULATIONS The ESA, 16 U.S.C. §§ 1531-1544, was enacted in 1973 “to provide a means whereby the ecosystems upon which endangered species and threatened species depend may be conserved, [and] to provide a program for the conservation of such endangered species and threatened species.” 16 U.S.C. § 1531(b). The protections of the ESA only apply to species that have been listed as endangered or threatened according to the provisions of the statute. The ESA delegates authority to determine whether a species should be listed as endangered or threatened to the Secretary of Interior, who has in turn delegated authority to the Director of the U.S. Fish & Wildlife Service. As defined in the ESA, an “endangered” species is one that is “in danger of extinction throughout all or a significant portion of its range.” 16 U.S.C. -

Ecology and Conservation of the Cactus Ferruginous Pygmy-Owl in Arizona
United States Department of Agriculture Ecology and Conservation Forest Service Rocky Mountain of the Cactus Ferruginous Research Station General Technical Report RMRS-GTR-43 Pygmy-Owl in Arizona January 2000 Abstract ____________________________________ Cartron, Jean-Luc E.; Finch, Deborah M., tech. eds. 2000. Ecology and conservation of the cactus ferruginous pygmy-owl in Arizona. Gen. Tech. Rep. RMRS-GTR-43. Ogden, UT: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 68 p. This report is the result of a cooperative effort by the Rocky Mountain Research Station and the USDA Forest Service Region 3, with participation by the Arizona Game and Fish Department and the Bureau of Land Management. It assesses the state of knowledge related to the conservation status of the cactus ferruginous pygmy-owl in Arizona. The population decline of this owl has been attributed to the loss of riparian areas before and after the turn of the 20th century. Currently, the cactus ferruginous pygmy-owl is chiefly found in southern Arizona in xeroriparian vegetation and well- structured upland desertscrub. The primary threat to the remaining pygmy-owl population appears to be continued habitat loss due to residential development. Important information gaps exist and prevent a full understanding of the current population status of the owl and its conservation needs.
