Monitoring spatial and temporal patterns in cetacean abundance involves a variety of
approaches depending upon the target species and the resources available. As a first step …

Baird's tapir (Tapirus bairdii) is endangered primarily because of habitat loss and
fragmentation, and overhunting throughout its distribution range (ca. 21,000 km2) in the …

The abstract concept of “information” can be quantified and this has led to many important
advances in the analysis of data in the empirical sciences. This text focuses on a science …

Indices to population size have come under increasing criticism in recent years, on the
grounds that indices might not faithfully represent the entire population. Most criticisms …

Recent field studies have suggested that the dynamics of West Nile virus (WNV)
transmission are influenced strongly by a few key super spreader bird species that function …

Methods are developed for estimating the size/density of cetacean populations using data
from a set of fixed passive acoustic sensors. The methods convert the number of detected …

This article develops methods for fitting spatial models to line transect data. These allow
animal density to be related to topographical, environmental, habitat, and other spatial …

Households across the developed world cumulatively spend many millions of dollars
annually on feeding garden birds. While beneficial effects on avian assemblages are …

An implicit assumption of standard line transect methodology is that detection probabilities
depend solely on the perpendicular distance of detected objects to the transect line …

In fragmented landscapes, species persistence within isolated habitat patches is governed
by a myriad of species life‐history, habitat patch and landscape characteristics. We …
