ESTIMATING SITE OCCUPANCY RATES WHEN DETECTION PROBABILITIES ARE LESS THAN ONE
Nondetection of a species at a site does not imply that the species is absent unless the probability of detection is 1. We propose a model and likelihood-based method for estimating site occupancy
Population declines in North American birds that migrate to the neotropics.
TLDR
Neotropical migrant species that primarily use forested habitats in either wintering or breeding areas are declining, but a statistically significant association between habitat and population declines was detected only in the tropics.
Managing and Monitoring Birds Using Point Counts: Standards and Applications
The use of population size as a measure of health of a species has been a very common tool of ornithologists for many years (Lack 1954, 1966; Hutchinson 1978). Methods for surveying population size
Tidal Marshes: A Global Perspective on the Evolution and Conservation of Their Terrestrial Vertebrates
TLDR
Tidal marshes and their endemic fauna face broad threats from a variety of human-caused environmental changes, and future research should focus on global inventories, intercontinental comparative work, and investigation to determine why almost all presently described endemic taxa appear to be found in North America.
Spatial patterns of bee captures in North American bowl trapping surveys
Abstract.  1. Bowl and pan traps are now commonly used to capture bees (Hymenoptera: Apiformes) for research and surveys.
Monitoring Bird Populations by Point Counts
This volume contains in part papers presented at the Symposium on Monitoring Bird Population Trends by Point Counts, which was held November 6-7, 1991, in Beltsville, Md., in response to the need for
Survey designs and statistical methods for the estimation of avian population trends
-The route-regression method has been used in recent years to analyze data from roadside surveys. With this method, a population tr~nd is estimated for each route in a region, then regional trends
