We surveyed anuran calls nightly at eight ponds in eastern Texas from 1 January 2001 through 31 December 2002. Air temperatures and daily rainfall also were recorded for each of the sites. Eastern Texas contains a diverse temperate anuran fauna and a climate that provides a range of conditions for anuran reproduction. During our study, we measured air(More)
—Amphibians are considered one of the most threatened vertebrate groups. Although numerous studies have addressed the many causes of amphibian population decline, little is known about effects of invasive plants. Chinese tallow (Triadica sebifera) is an exotic deciduous tree that has invaded the southeastern United States. Amphibian larvae in environments(More)
Chinese tallow (Triadica sebifera (L.) Small) is an aggressive invasive tree species that can be abundant in parts of its non-native range. This tree species has the capability of producing monocultures, by outcompeting native trees, which can be in or near wetlands that are utilized by breeding amphibians. Existing research suggests that leaf litter from(More)
occupancy of 240 nest boxes in pure pine, pine-hardwood, upland hardwood, and bottomland hardwood forests (60 boxes in each forest type) were monitored for six years on the Stephen F. Austin Experimental Forest, Nacogdoches County in eastern Texas. Three boxes were placed at twenty sites in each forest type. Initially, each site had a box with 3.2, 4.7, or(More)
We tested the hypotheses that potential egg predators, crayfish Procambarus nigrocinctus and dytiscid Cybister sp. larvae, would accelerate the timing of hatching and that a larval predator, dragonfly naiad Anax junius, would delay hatching in the southern leopard frog (Rana sphenocephala). We also tested the hypothesis that differences in response would be(More)
Arthropod density on the boles of loblolly pines (Pir~s tczdu) was compared between a stand with and stand without hardwood midstory and between a stand of loblolly and shortleaf pines (p cckirzntn) in an open pine stand nearly devoid of hardwood midstory than in a pine stand with dense hardwood midstory. Loblolly pine had greater (t = 2.34, 10.9 d.f., P =(More)
Diet and prey handling behavior were determined for Louisiana pine snakes (Pituophis ruthverzi) and black pine snakes (E n7elarzolrucu.~ lodingi). Louisiana pine snakes prey heavily on Baird's pocket gophers (Gporn~s hrevicqs), with which they are sympatric, and exhibit specialized behaviors that facilitate handling this prey species within the confines of(More)
The effects of Red-cockaded Woodpecker (Picoi&s bo~~~cr/i.r) rnanagenxm on nontarget birds is not widely known. Intensive managentcnt for-pine specialists such as the Red-cockaded Woodpecker may negatively impact both Nenrctic-Neotl-apical and Temperate Zone migrants associated with hardwood vegetation. 'lb evaluate possible pctsitive and negative(More)
For several decades general opinion has suggested that southern flying squirrels (Gluucomys volans) have a negative effect on Red-cockaded Woodpeckers (Picoides borealis) through competition for cavities and egg/nestling predation. Complete removal of hardwood trees from Red-cockaded Woodpecker cavity tree clusters has occurred on some forests because(More)
