Natural establishment of woody species on abandoned agricultural fields in the lower Mississippi Valley: first- and second-year results Natural establishment of woody species on abandoned agricultural fields in the lower Mississippi Valley: first- and second-year results
The natural establishment of woody seedlings on abandoned agricultural fields was investigated at sites in Louisiana and Mississippi. Series of disked and undisked plots originating at forest edges and oriented in cardinal directions were established on fields at each site. During the firest 2 years, seedling recruitment was dominated by sweetgum, sugarberry, and elms at both sites...

Effects of flooding regime, mycorrhizal inoculation and seedling treatment type on first-year survival of Nuttal Oak (Quercus nuttallii Palmer) Effects of flooding regime, mycorrhizal inoculation and seedling treatment type on first-year survival of Nuttal Oak (Quercus nuttallii Palmer)
Three different types of Nuttall oak (Quercus nuttallii Palmer) seedlings were planted on floodprone, former cropland in Mississippi, Louisiana, and Texas. The three types of 1+0 seedlings planted at each site in January and February of 1995 were bareroot seedlings, seedlings grown in 164 square centimeters plastic containers, and container grown seedlings inoculated with vegetative...

Characterization of an old-growth bottomland hardwood wetland forest in Northeast Texas: Harrison Bayou Characterization of an old-growth bottomland hardwood wetland forest in Northeast Texas: Harrison Bayou
Most wetland losses in the southern region over the past 200 years have occurred in bottomland hardwood forests. By 1980 the original extent of palustrine bottomland in Texas had been reduced by 63%, from roughly 16 to 6 million acres. Additional losses have occurred during more recent years as a result of conversion to agriculture and timber harvests; these factors and the need to...

Comparative sensitivity of five species of macrophytes and six species of algae to atrazine, metribuzin, alachlor, and metolachlor Comparative sensitivity of five species of macrophytes and six species of algae to atrazine, metribuzin, alachlor, and metolachlor
This study determined the relative sensitivity of five species of aquatic macrophytes and six species of algae to four commonly used herbicides (atrazine, metribuzin, alachlor, and metolachlor). Toxicity tests consisted of 96-h (duckweed and algae) or 14-d (submerged macrophytes) static exposures. The triazine herbicides (atrazine and metribuzin) were significantly more toxic to aquatic...

Common and scientific names of aquatic invertebrates from the United States and Canada: Mollusks Common and scientific names of aquatic invertebrates from the United States and Canada: Mollusks
This edition of Common and Scientific Names of Invertebrates from the United States and Canada: Mollusks represents the efforts of 15 molluscan taxonomic specialists in compiling a comprehensive checklist of the mollusks found in North America and Canada and their vernacular names. Built upon the success of the first edition, the authors have updated the nomenclature to reflect recent...

Long-term growth enhancement of baldcypress (Taxodium distichum) from municipal wastewater application Long-term growth enhancement of baldcypress (Taxodium distichum) from municipal wastewater application
Tree ring analysis was used to document the long-term effects of municipal wastewater on the growth rate of baldcypress (Taxodium distichum (L.) Rich.]. The study site, a swamp in St. Martin Parish, Louisiana, has received municipal wastewater for the last 40 years. Growth chronologies from 1920 to 1992 were developed from cross-dated tree core samples taken from treated and control...

Long-term dynamics of Typha populations Long-term dynamics of Typha populations
The zonation of Typha populations in an experimental pond in Michigan was re-examined 15 years after the original sampling to gain insight into the long-term dynamics. Current distributions of Typha populations were also examined in additional experimental ponds at the site that have been maintained for 23 years. The zonation between T. latifolia and T. angustifolia in the previously...
