Grasshopper crop and midgut extract effects on plants: an example of reward feedback.

Acid extracts and a resultant fraction from solid-phase extraction (SPE) of Romalea guttata crop and midgut tissues induce sorghum (Sorghum bicolor var. Rio) coleoptile growth in 24-h incubations an average of 49% above untreated controls. When combined with plant auxin, indole-3-acetic acid (IAA), the SPE fraction shows a synergistic reaction, yielding increases in coleoptile growth that average 295% above untreated controls and 8% above IAA standards. The interaction lowered the point of maximum sensitivity of IAA 3 orders of magnitude, resulting in a new IAA physiological set point at 10(-7) g/ml. This synergism suggests that contents in animal regurgitants making their way into plant tissue during feeding may produce a positive feedback in plant growth and development following herbivory. Such a process, also known as reward feedback, may exert major controls on ecosystem-level relationships in nature.

Ethnobotanical study of the sages used in traditional Valencian medicine and as essential oil: characterization of an endemic Salvia and its contribution to local development

Seven wild and cultivated Salvia species and two Phlomis species, used traditionally in Valencian medicine to treat a variety of external and internal ailments, were studied. New ethnobotanical data are provided, obtained from semistructured interviews with 34 people in the Valencian area. A seasonal characterization of the essential oil of a wild sage, Salvia blancoana Webb & Heldr. subsp. mariolensis Figuerola, by GC-FID and GC-MS was carried out as a means to ensure quality control of endemic traditional species such as this one, which has been commercialized by local industries. A comparison with the essential oil of Salvia lavandulifolia Vahl subsp.lavandulifolia allowed inclusion of the wild sage within the commercial 'Spanish sage' oil.

Rosa gallica l. var. officinalis (hort. ex Andrews) Ser. en el norte de Alicante (Comunidad Valenciana)

Se ha localizado en el margen de la carretera comarcal CV 795 en su kilómetro 17 próximo a Ulls de Canals y dentro del término de Banyeres de Mariola, una buena población asilvestrada de Rosa gallica L. var. officinalis (hort. ex Andrews) Ser., que corresponde a la segunda población localizada en Alicante, puesto que se conocía una población pero situada próxima al litoral en la comarca de la Marina Alta. La llamada rosa de Provins o provincialis (de Provenza) es una de las rosas cultivadas en Europa desde más antiguo, probablemente la primera. Aparece dibujada en los frescos de Pompeya, fue también la rosa de las boticas (“Officinalis”) y se corresponde con la famosa rosa roja o Rosa de Lancanster, símbolo de este bando en la Guerra de civil inglesa llamada de “las dos rosas”. Su cultivo en España fue muy importante y era frecuentemente citada en la literatura botánica antigua, fue llamada “rosa de Castilla” pero con el tiempo y el abandono del campo, su presencia fue disminuyendo y de forma asilvestrada solo aparece en unas pocas provincias españolas, aunque se sigue manteniendo su cultivo a pequeña escala en colecciones particulares y rosaledas. Precisamente, en la Rosaleda “Pere Dot” del Jardín Botánico de Torretes (Ibi) mantenemos en cultivo dos de las variedades botánicas reconocidas y muchos de los cultivares e híbridos de este rosal, que hemos adquirido de colecciones extranjeras. El hallazgo de este material asilvestrado probablemente procedente de antiguos cultivos en la zona, tiene gran valor etnobotánico y puede tener valor genético. Aunque en su morfología no se han encontrado diferencias relevantes, se ha procedido a su multiplicación vegetativa y será próximamente incluido en la rosaleda del Jardín Botánico, junto con pliegos de herbario y semillas.

Extract from legislation passed 1799 February 7

One fragment of a leaf containing a handwritten extract from unidentified legislation stipulating that a section of the bill "should not be so construed as to exempt" the real estate of the College or its officers from payment of local taxes beyond that exempted in the Charter of 1650 and the state Constitution. The text includes the note, "passed 7 Feb'y --99" and presumably refers to the bill referenced in President Willard's letter to Samuel Phillips that "passed the House, and is now before the Senate." The section did not become part of the tax law.

No. 2 Extract from the Charter of 1650, [1799]

Two octavo-sized leaves containing a one-page handwritten copy of the section of the Charter of 1650 providing tax exemptions to Harvard College officers. The transcription is signed as a "True copy" by President Willard.
