Use of IPA to demonstrate loss of forest interior birds from isolated woodlots
'Empleo de indices puntuales de abundancia (IPA) para demostrar la perdida de aves forestales en bosques aislados'. En Maryland, E.U., se seleccionaron bloques boscosos de diferente superficie, divididos en seis clase de tamano (2,8-6 ha, 7-14, 20-30, 34-80, 105-1300, mayores de 4000 ha). En estas ?islas' forestales fue programado un conjunto de muestreos puntuales con estas caracteristicas: 1)

Environmental contaminants in tissues, foods, and feces of California condors
Two wild California Condors contained moderate to high levels of DDE in their tissues. The levels found could be high enough to cause reproductive problems in adult condors, if the assumption is made that condors are as susceptible to DDE as many other species of birds of prey. Other organochlorines occurred at low levels and probably were not high enough to cause deleterious effects. Metal resi

Effects of the insecticide, orthene, on unconfined populations of the meadow vole (Microtus pennsylvanicus). I. Capture/recapture procedures; II. Residues and cholinesterase inhibition
In 1982 and 1983. the population demography of M. pennsylvanicus was not altered significantly by single or double applications of Orthene. Although inconsistencies in population size, survival, and recruitment were not explained by differences between control and experimental grids in breeding, emigration, interspecific competition, or pesticide-induced mortality, there may have been fundamental
