Grace Bumbry Made Santuzza Role Debut at Met Opera in Zeffirelli’s Cav Pag

Summary: Grace Bumbry made her Santuzza role debut at Met Opera in Zeffirelli’s Cav Pag, the Italian designer, director and producer’s third Met Opera staging.

American mezzo-soprano Grace Bumbry’s appearances in the 1969-1970 Met Opera season as Santuzza in Franco Zeffirelli’s new staging of Pietro Mascagni’s Cavalleria Rusticana added the fifth of 14 career roles to her Met Opera portfolio: Fondazione Franco Zeffirelli Onlus @fondazionefrancozeffirelli, via Facebook Dec. 24, 2018

Grace Bumbry made her Santuzza role debut at Met Opera in Zeffirelli’s Cav Pag, the Italian designer, director and producer’s third production at the opera house.

American mezzo-soprano Grace Bumbry (born Jan. 4, 1937) added her fifth role debut to her Met Opera portfolio with her appearance as seduced Santuzza in the opening night performance of the 1969-1970 season’s new production of Cavalleria Rusticana by Italian opera composer Pietro Mascagni (Dec. 7, 1863-Aug. 2, 1945). The rustic Sicilian opera’s new staging by Franco Zeffirelli (Feb. 12, 1923-June 15, 2019) debuted Jan. 8, 1970, as a double header with Zeffirelli’s new production of Pagliacci by Italian opera composer and librettist Ruggero Leoncavallo (April 23, 1857-Aug. 9, 1919). Each opera received 19 performances in the 1969-1970 season.

Grace Bumbry sang Santuzza in the new production’s first five performances. Italian tenor Franco Corelli (April 8, 1921-Oct. 29, 2003) joined her as Santuzza’s seducer, Turiddu, in the first five performances.

The Metropolitan Opera staged 16 revivals of Zeffirelli’s Cav Pag production. Grace Bumbry reprised Santuzza in four revivals.

In the 1971-1972 season, she returned for two of the second revival’s 14 performances. She sang opposite American operatic tenor Barry Morell (March 30, 1927-Dec. 4, 2003) in the fifth performance, Oct. 16, 1971. For the sixth performance, Oct. 23, she sang opposite American operatic tenor Enrico Di Giuseppe (Oct. 14, 1932-Dec. 31, 2005) for the next performance, Oct. 23.

Bumbry reprised Santuzza in the 1974-1975 season for the production’s fourth revival. She appeared in eight of the fourth revival’s 22 performances.

She sang in the revival’s first four performances. Italian operatic tenor Franco Tagliavini (Oc. 29, 1934-Aug. 15, 2010) was Bumbry’s Turiddu in the first three performances. American operatic tenor Harry Theyard (born Sept. 28, 1929) sang Turiddu for the fourth performance.

Bumbry also appeared in the fourth revival’s ninth, 10th, 11th and 14th performances. American operatic tenor William Lewis (born Nov. 23, 1935) sang opposite her for the revival’s ninth performance. Harry Treyard returned as Turiddu for the 10th and 14th performances. Franco Corelli returned for the revival’s 11th performance, on Dec. 23, 1974, to sing Turiddu for the last time at the opera house.

The Metropolitan Opera’s fifth revival of Zeffirelli’s Cav Pag took place in the 1977-1978 season. Bumbry reprised Santuzza on Jan. 11, 1978, for the third of the revival’s 20 performances.

The Metropolitan Opera staged the production’s seventh revival in the 1980-1981 season. Bumbry sang Santuzza for the first six of the revival’s 17 performances. Italian tenor Carlo Bini appeared opposite Bumbry’s Santuzza.

Bumbry retired Santuzza from her active Met Opera repertoire during the seventh revival. Her appearance Jan. 10, 1981, in the revival’s sixth performance, marked her 22nd appearance as Santuzza in Zeffirelli’s production.

Grace Bumbry had made her Met Opera debut Oct. 7, 1965, as Princess Eboli in the opera house’s 65th performance of Don Carlo by 19th-century Italian opera composer Giuseppe Verdi (Oct. 10, 1813-Jan. 27, 1901). She made her second and third role debuts at Met Opera in the following season, 1966-1967, with performances as Amneris in Verdi’s Aida and as Azucena in Il Trovatore.

Bumbry made her fourth role debut at Met Opera in the next season, 1967-1968. She sang the title role in Carmen by French Romantic Era composer Georges Bizet (Oct. 25, 1838-June 3, 1875).

After her fifth role debut as Santuzza in the 1969-1970 season, she claimed her sixth and seventh Met Opera roles in the 1970-1971 season. She sang title roles in Orfeo ed Euridice by German classical composer Christoph von Gluck (July 2, 1714-Nov. 15, 1787) and Tosca by Italian opera composer Giacomo Puccini (Dec. 22, 1858-Nov. 29, 1924).

The 1971-1972 season added an eighth role debut to Bumbry’s Met Opera portfolio. She sang the title role in Samson et Dalila by French Romantic Era composer Camille Saint-Saëns (Oct. 9, 1835-Dec. 16, 1921).

In the 1972-1973 season, Grace Bumbry returned to Verdi for her fourth Verdi opera and ninth role debut at the Metropolitan Opera. She appeared as Lady Macbeth in Verdi’s first Shakespearean opera, Macbeth.

Bumbry’s 10th role debut took place in the following season, 1973-1974. She sang the title role in Salome by German late Romantic-early modern composer Richard Strauss (June 11, 1864-Sept. 8, 1949).

The 1977-1978 season marked Bumbry’s 11th role debut. She appeared as Venus in Tannhäuser by German composer and librettist Wilhelm Richard Wagner (May 22, 1813-Feb. 13, 1883).

Two seasons later, in 1979-1980, Bumbry claimed her 12th role debut. She sang the title role in La Gioconda by 19th-century Italian opera composer Amilcare Ponchielli (Aug. 31, 1834-Jan. 16, 1886).

Bumbry returned to Verdi for her 13th role debut in the 1983-1984 season. She appeared as Leonora in La Forza del Destino, her fifth Verdi opera at the opera house.

Bumbry’s 14th and last role debut occurred in the 1984-1985 season. She sang the title role in Porgy and Bess by American composer and pianist George Gershwin (Sept. 26, 1898-July 11, 1937).

Bumbry reprised her second role debut for her last active season at Met Opera, 1986-1987. Her last performance as Amneris in Verdi’s Aida took place Nov. 3, 1986.

Grace Bumbry returned to the Metropolitan Opera almost nine and one-half years later for her last appearance at the opera house. On April 27, 1996, she sang “Mon coeur s'ouvre à ta voix” (Saint-Saëns’ Samson et Dalila, Act 2) in the 25th Anniversary Gala for the Metropolitan Opera House’s second music director, James Levine.

The takeaways for Grace Bumbry's making her Santuzza role debut at Met Opera in Zeffirelli’s Cav Pag are that Zeffirelli’s new production of Pietro Mascagni’s Cavalleria Rusticana added Bumbry’s fifth role debut to her Met Opera portfolio and that the American mezzo-soprano reprised the role in four of the production’s 16 revivals.

Mountain River Cruiser Dragonfly Habitats: Big Eyes, Slanted Stripes

Summary: North American mountain river cruiser dragonfly habitats get big eyes, brown wings, dark, long, spiny legs, slant-striped thoraxes and spotted abdomens.

Mountain River Cruiser damselfly (Macromia margarita) belongs to the Macromia genus; Macromia species with prey depicted as "The Dragonfly and its Victim" in D. and M. Fairchild, Book of Monsters (1914), page 194: No known restrictions, via Wikimedia Commons

North American mountain river cruiser dragonfly habitats attract cultivators with clean water and naturalists with distribution ranges between Alabama and Mississippi and into Georgia, South Carolina, North Carolina, Virginia, Tennessee and Kentucky.

Mountain river cruisers bear their common name for long male mate-seeking patrols of mountain rivers and the scientific name Macromia margarita (Margaret's equally long [large dragonfly]). The species' scientific name margarita commemorates Margaret Lucille Shepherd Westfall (Aug. 5, 1921-Feb. 9, 2000), wife of Minter Jackson Westfall, Jr. (Jan. 28, 1916-July 20, 2003). Scientific designations defer to descriptions in 1947 by Dr. Westfall, co-founder of the International Odonata Research Institute and entomologist at the University of Florida in Gainesville.

Mountain river cruiser dragonfly life cycles expect clean Piedmont and rocky mountain rivers and streams with good currents, open woodlands and perch-friendly waterside shrubs and trees.

June through August function as earliest to latest flight seasons even though June furnishes wildlife mapping opportunities in all of North America's mountain river cruiser niches.

Mountain river cruisers go from night-time resting roosts to daytime hunting, patrolling and pre-mating perches on stems and twigs in brushy, shrubby, woody nearby waterside vegetation. Each morning they head back and forth over the same 100-yard (91.44-meter) shorelines alongside, and stretches of, southeastern rivers and streams at swift sustained cruising speeds. They imprison aquatic and terrestrial low-flying and low-lying motionless and moving invertebrate prey within black, clawed, long, ridged, spiny, three-segmented legs and projectable, retractable lower lips.

Ants, biting midges, ducks, falcons, fish, flycatchers, frogs, grebes, lizards, robber flies, spiders, turtles and water beetles and mites jeopardize North American mountain river cruiser habitats.

Immature mountain river cruiser dragonflies keep dull, faded, light, pale colors and small sizes even though adults know brilliant blacks, greens and yellows and large sizes.

Incomplete metamorphosis links green, round eggs laid by females at high speeds over water surfaces, little adult-like, multi-molting, nonflying larvae, naiads or nymphs and molted tenerals. Brown-eyed, shiny-winged, soft-bodied, weak-flying tenerals manage physical and sexual maturation away from water and move back to mate in trees and manipulate eggs into ovipositing sites. River cruiser members of the Macromiidae cruiser family need aphids, beetles, borers, caddisflies, copepods, crane flies, dobsonflies, gnats, leafhoppers, mosquitoes, rotifers, scuds, water fleas and worms.

North American mountain river cruiser habitats offer season-coldest temperatures, north- to southward, from minus 5 to 0 degrees Fahrenheit (minus 20.55 to minus 17.77 degrees Celsius).

Beech, bellflower, birch, bladderwort, cattail, daisy, grass, greenbrier, heath, laurel, madder, maple, nettle, olive, pepperbush, pine, pondweed, rush, sedge, water-lily and willow families promote mountain river cruisers.

Brown-tinted wings, single-, yellow-, side-striped black thoraxes, small yellow eyespots, yellow-banded black faces and yellow-spotted black abdomens with interrupted yellow rings qualify as adult female hallmarks. Adult males reveal the same shiny black bodies and yellow spots and stripes even though they retain big, bright green eyes and clubbed, not cylindrical, abdomens. Adults show off 2.84- to 3.07-inch (72- to 78-millimeter) head-body lengths, 49- to 57-inch (1.93- to 2.24-millimeter) abdomens and 1.81- to 2.05-inch (46- to 52-millimeter) hindwings.

Single-, slant-striped thoraxes and spotted abdomens with one broken ring tell big-eyed, brown-winged, spiny-legged mountain river cruisers from other odonates in mountain river cruiser dragonfly habitats.

The Mountain River Cruiser damselfly (Macromia margarita) is found in the American Southeast (Alabama, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, Tennessee, Virginia); NOAA-20 Visible Infrared Imaging Radiometer Suite (VIIRS) satellite image of Southeastern United States obtained Dec. 13, 2017, at 18:54 Coordinated Universal Time (UTC): Public Domain, via Wikimedia Commons

Lignotubers Assure Arboricultural Management of Lignotuberous Shoots

Summary: Lignotubers assure arboricultural management of lignotuberous shoots from lignotuberous buds, according to G. M. Moore in the June 2020 Arborist News.

lignotubers at base/root-collar of shoots of Eucalyptus (Eucalyptus spp.): Edward L. Barnard, Florida Department of Agriculture and Consumer Services, Bugwood.org, CC BY 3.0 United States, via Forestry Images

Lignotubers assure stress-alleviating arboricultural management of lignotuberous shoots from lignotuberous buds, according to the June 2020 Arborist News article, Managing Dormant Buds as Arboricultural Assets: Lignotubers (Basal Burls) by G. M. Moore.

Lignotuberous shoots, with strong attachments to root systems, boast strong-trunked 20.34-foot- (6.2-meter-), 61.02-foot- (18.6-meter-) and 101.71-foot- (31-meter-) tall trees respectively within one, three and five years. Big-leaf maple (Acer macrophyllum), coastal redwood (Sequoia sempervirens), huckleberry (Vaccinium parvifolium), maidenhair (Ginkgo biloba), mountain laurel (Umbellularia californica) and rhododendron (Rhododendron macrophyllum) count among lignotuberous species. Lignotubers (from Latin lignum, "wood" and tūber, "bump") develop, as basal swellings, from axillary lignotuberous buds at the first three leaf nodes on young seedling stems.

Arboricultural management esteems lignotubers

Dormant lignotuberous buds with ready reserves of stored carbohydrates furnish lignotuberous species with full energy levels for flourishing fast-growing lignotuberous shoots during extreme, severe environmental stress.

Lignotubers generally generate lignotuberous shoots from dormant lignotuberous buds only after all other tree shoots and their tree canopies, crowns and trunks get damaged and destroyed. Such extreme, severe environmental stresses as high temperatures during wildfires harm no lignotubers, whose below-ground huddling has help from high insulating properties of the surrounding soil. Ninety percent of 700 Eucalyptus species include lignotubers even though harsh, stressful versus cool, temperate, wet environments re

Arboricultural management judges lignotubers ideally juggling lignotuberous shoots at weekly 11.02-inch (28-centimeter) ahormonally-controlled rates through judicious attachments to established roots' carbohydrate reserves and nutrient-absorbing, water-absorbing capacities.

Keeping one to few strongly-attached shoots from late-winter to early-spring formative and structural pruning kindles raised-canopy, single-stemmed trees, not bushy, codominant-stemmed, low-growing trees with included bark.

Arboricultural management links length-limiting, pruning, weight-limiting schedules and pruning and thinning schedules to sound branch anatomies for epicormic shoots and single-stem, single-trunk structures for lignotuberous shoots. Higher branch/stem nodes versus the stem's first three leaf nodes respectively manifest epicormic-bud versus lignotuberous-bud mortality rates of 0 to 50 versus 50 to 100 percent. Initial response mechanisms net epicormic shoots with weak root attachments within days of moderate-stress, high-stress branching, leafed-out canopy loss, for photosynthesizing replacements within weeks to months.

Lignotubers offer last-resort survival shoots re-sprouted with strong root attachments within weeks of high-stress, severe-stress canopy and trunk damage, into single-stem, single-trunk replacements within several years.

Urban tree management prefers placing, when visual identification proves problematic, shoots proximitous to trunk bases in the less manageable, riskier category of epicormic, not lignotuberous, shoots.

Lignotuberous shoots at tree bases to intact canopies and trunks qualify as usual signs of environmental stress, with ready remedies, or poor management, with difficult resolutions. They realize greater mortality than epicormic shoots and require of urban tree management regular inspections the first weeks and the spring after damage, fire and pruning. Swift-growing shoots shelter stored carbohydrates whose significant supplies support their damaged, structurally-weakened trees' large, mature, valuable roots for branch and canopy re-establishment and anti-disease, anti-pest energy.

Lignotubers tally cheaper, faster returns of amenity value than newly-planted, same-species, slower-growing seedlings through attachment to established, large root systems and significant reserves of stored carbohydrates.
