Marine and terrestrial studies show that small, sedentary herbivores that utilize plants as both food and habitat can gain enemy-free space by living on hosts that are chemically defended from larger, generalist consumers. Although large herbivores a

Examination of the aerial portions of Cleome spinosa yielded five new cembranes, named cleospinols A (1), B (3), C (4), and D (5), and the 3'-hydroxy-iso-pentan-10-oate ester of cleospinol A (2). The cleospinols were determined to be derivatives of 1

The naturally occurring sesquiterpene squamulosone ( 1 ), isolated from Hyptis verticillata (Labiatae), was synthetically reduced to five analogues that were identified as (1 S ,10 S )-9α-hydroxy- allo -aromadendrane ( 2 ), (1 R ,10 R )-9β-hydroxya

Bioconversion of cedrol (1) with the Curvularia lunata was investigated in two different growth media. Five products were obtained in potato dextrose broth, whereas nine compounds were produced in a medium containing beef extract. Only three of the m

Four structurally novel isomeric sesquiterpenes have been isolated from the aerial parts of Capraria biflora. Caprariolides A (1), B (2), C (3), and D (4) have been determined by NMR spectroscopy experiments to be the (3S,5S,9R), (3R,5S,9R), (3R,5R,9

Five of the most common macrophytes from an aquaculture facility with high densities of the herbivorous Asian grass carp (Ctenopharyngodon idella) were commonly unpalatable to three generalist consumers-grass carp and the native North American crayfi

Pathogenic microbes can devastate populations of marine plants and animals. Yet, many sessile organisms such as seaweeds and sponges suffer remarkably low levels of microbial infection, despite lacking cell-based immune systems. Antimicrobial defense
