Relative costs of prebasic and prealternate molts for male blue-winged teal Relative costs of prebasic and prealternate molts for male blue-winged teal
We compared masses of definitive basic and alternate plumages of male Blue-winged Teal (Anas discors) to evaluate the hypothesis that nutritional investments in basic and alternate plumages are related to the duration that plumages are worn and to assess the relative costs of prebasic and prealternate molts. Because these plumages are worn by males for approximately equal durations, we...

Long-term growth trends of baldcypress (Taxodium distichum (L.) rich.) at Caddo Lake, Texas Long-term growth trends of baldcypress (Taxodium distichum (L.) rich.) at Caddo Lake, Texas
Caddo Lake, situated on the border of northeast Texas and northwest Louisiana, USA is a medium-sized lake dominated by stands of baldcypress (Taxodiwn distichum). A study of tree growth was initiated at Caddo Lake to address concerns about the health of the baldcypress ecosystem. The lake has been subjected to several dramatic water-level changes over the past 200 years, including water...

Vertebrate herbivory in managed coastal wetlands: A manipulative experiment Vertebrate herbivory in managed coastal wetlands: A manipulative experiment
Structural marsh management and nutria herbivory are both believed to strongly influence plant production in the brackish, deltaic marshes of coastal Louisiana, USA. Previous studies have tested the effects of structural management on aboveground biomass after implementing management, but very few studies have collected data before and after management. Thus, to test the effects of...

Source-sink dynamics and the coexistence of species on a single resource Source-sink dynamics and the coexistence of species on a single resource
We investigate the potential for coexistence of species that compete for a shared resource when the resource occurs in both a source area acting as a refuge and a sink area where it is used by the competing species. Our model shows that the mixing rate between the source and sink resource populations has a dramatic influence on the outcome of competition. When there is a strict sink...

Use of inexpensive pressure transducers for measuring water levels in wells Use of inexpensive pressure transducers for measuring water levels in wells
Frequent measurement of below ground water levels at multiple locations is an important component of many wetland ecosystem studies. These measurements, however, are usually time consuming, labor intensive, and expensive. This paper describes a water-level sensor that is inexpensive and easy to construct. The sensor is placed below the expected low water level in a shallow well and, when...
