Chewing-removal of radio collars by wolves in Wisconsin Chewing-removal of radio collars by wolves in Wisconsin
From May 1980 through august 1981 we placed 11 machine-belt radio collars on 10 adult gray wolves (Canis lupus) from 4 packs in northwestern Wisconsin. This note reports the loss of 7 collars from chewing by other wolves, apparently pack-mates.

Estimation methodology in contemporary small mammal capture-recapture studies Estimation methodology in contemporary small mammal capture-recapture studies
Estimators of population size and survival rate based on the Jolly-Seber capture-recapture model and the “enumeration method” are described. Enumeration estimators are shown to estimate complicated functions of capture and survival probabilities and, in the case of the population size estimator, population size. Frequently-listed reasons for preferring enumeration estimators are...

Use of IPA to demonstrate loss of forest interior birds from isolated woodlots 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...

Crane reproductive physiology and conservation Crane reproductive physiology and conservation
Some unique features of crane reproduction, management, and conservation are described. Because cranes are sexually monomorphic, sexing is difficult and must be accomplished using behavior, laparoscopy, cloacal examination, genetic techniques, or fecal steroid analysis. Although husbandry techniques for cranes are similar to those used with other nondomestic birds, a number of basic

Factors affecting the distribution of mallards wintering in the Mississippi Alluvial Valley Factors affecting the distribution of mallards wintering in the Mississippi Alluvial Valley
The Mississippi Alluvial Valley (MAV) is the principal wintering area for Mallards (Anas platyrhynchos) in the Mississippi Flyway. Here, we consider it a distinct habitat (sensu Fretwell 1972), i.e. fitness is relatively homogeneous among ducks within the MAV but different from that of ducks in other such habitats. We analyzed recovery distributions of Mallards banded preseason (July...

Fifty-ninth Christmas Bird Count. 176. Ocean City, Md Fifty-ninth Christmas Bird Count. 176. Ocean City, Md
Some organophosphorus insecticides have been reported to interfere with reproduction and even cause the decline of small mammal populations. The effects of such anticholinesterases on plasma LH concentrations were examined in male mice (Peromyscus leucopus noveboracensis) intubated with water (OW) or acephate (50 and 100 mg/kg) and sacrificed after 4 h. Brain acetylcholinesterase (AChE)...
