{"product_id":"9780999702901","title":"Oasis at the Desert Edge: Flora of Cañón del Nacapule, Sonora, Mexico","description":"\u003cp\u003eCañón del Nacapule cuts into the southeastern flank of the Sierra El Aguaje, a rugged\u003c\/p\u003e\u003cp\u003evolcanic range about 20 kilometers northwest of Guaymas. Nacapule is included in the\u003c\/p\u003e\u003cp\u003eSonoran segment of the Gulf Coast subdivision of the Sonoran Desert. The bi-seasonal\u003c\/p\u003e\u003cp\u003e(summer and winter) rainfall is highly variable. Many plants of tropical origin reach their\u003c\/p\u003e\u003cp\u003enorthern limits in this region or do not extend farther north in the arid coastal desert\u003c\/p\u003e\u003cp\u003eof western Sonora. The vegetation in the canyon resembles tropical thornscrub and approaches\u003c\/p\u003e\u003cp\u003ethe character of tropical deciduous forest in the wetter and shaded habitats,\u003c\/p\u003e\u003cp\u003ewhile the steep canyon walls and exposed habitats support desertscrub. The Nacapule\u003c\/p\u003e\u003cp\u003eflora includes 310 species in 233 genera and 72 families. The most diverse families are\u003c\/p\u003e\u003cp\u003eFabaceae, Asteraceae, Poaceae, Malvaceae, Euphorbiaceae, and Cactaceae. Brief species\u003c\/p\u003e\u003cp\u003eaccounts and identification keys as well as over 300 color photos are provided for the flora\u003c\/p\u003e\u003cp\u003eknown from the canyon, nearby Nacapule Spring, and within 500 meters of the canyon\u003c\/p\u003e\u003cp\u003emouth. \u003cem\u003eVerbesina felgeri\u003c\/em\u003e is endemic to the Sierra El Aguaje, and geographically isolated\u003c\/p\u003e\u003cp\u003epopulations of tropical genera such as \u003cem\u003eAphanosperma\u003c\/em\u003e, \u003cem\u003eBriquetia\u003c\/em\u003e, \u003cem\u003eCoccoloba\u003c\/em\u003e, and \u003cem\u003eFicus\u003c\/em\u003e occur\u003c\/p\u003e\u003cp\u003ein the canyon. Plants not native to the Guaymas region, mostly Old World weeds, are\u003c\/p\u003e\u003cp\u003erepresented by 19 species, three of which are not established as reproducing populations,\u003c\/p\u003e\u003cp\u003eincluding \u003cem\u003eCorchorus olitorius\u003c\/em\u003e, a new record for the state of Sonora. The canyon is managed\u003c\/p\u003e\u003cp\u003efor ecotourism by the local property owners, restoring earlier habitat degradation. Cañón\u003c\/p\u003e\u003cp\u003edel Nacapule, with 291 native species, provides conservation for 42% of the total native\u003c\/p\u003e\u003cp\u003eflora (ca. 700 taxa) of the 532,000 hectares (5320 km\u003csup\u003e2\u003c\/sup\u003e) of the greater Guaymas region.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e","brand":"Desert Laboratory on Tumamoc Hill","offers":[{"title":"Default Title","offer_id":47029980070128,"sku":"9780999702901","price":30.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9780999702901_p0.jpg?v=1763899526","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780999702901","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
