Journal of the Agricultural and Applied Economics Association, EarlyView.Abstract This paper derives the asymptotic properties of an iterated three‐stage least squares (I3SLS) estimator and applies it to estimate a Quadratic Almost Ideal Demand (QUAID) system for 47 fruits and vegetables with endogenous prices. We calculate an exact price index from the estimates and compare it with several commonly used price indexes.

Taxonomic novelties in subgenus Euphorbia (Euphorbiaceae) from South India
Nordic Journal of Botany, EarlyView.Extensive floristic explorations throughout southern India have uncovered some noteworthy taxonomic additions within the subgenus Euphorbia (Euphorbiaceae). Three distinct taxa of Euphorbia are described and illustrated herein as E. sankarensis, E. bahalita and E. tortilis var. mysorensis.

POSTHARVEST PERFORMANCE OF WHITE AND GREEN ASPARAGUS SPEARS [PDF]
HortScience, 1991 Black and white plastic row covers were established over 4 yr old field-grown 'Jersey Giant' asparagus in March 1990 to produce white asparagus spears. Control or green spears were grown without row covers. Spears harvested between Apr 27 and May 18 were used in subsequent experiments.

Oikos, EarlyView.By dispersing seeds, frugivorous animals affect spatial co‐occurrence of plants, ultimately influencing plant community dynamics. Frugivorous animals are intrinsically involved in plant community dynamics, by dispersing seeds of fleshy‐fruited plants and influencing their spatial co‐occurrence.

Cotton facilitates long‐distance seed dispersal by functioning as nest material for birds
Oikos, EarlyView.Cotton (Cossypium) fibres, which grow naturally in bolls around the seeds of cotton plants, have been used for centuries to produce fabric. The presumed natural function of cotton is that these lightweight and fluffy fibres may support wind dispersal of the seeds inside.
