Results of an experiment to lead cranes on migration behind motorized ground vehicles Results of an experiment to lead cranes on migration behind motorized ground vehicles
Ten greater sandhill cranes (Grus canadensis tabida), trained to enter and ride in a specially equipped truck, were transported at 80? days of age from their rearing site at Patuxent Wildlife Research Center (Patuxent), Maryland, to a reintroduction site located within the species? former breeding range in northern Arizona. After 5 additional weeks of training, these juvenile cranes were...

The name of Lawrence's flycatcher The name of Lawrence's flycatcher
If Lawrence's flycatcher of Grenada, Trinidad, and northern South America is placed in the genus Lathrotriccus with the species euleri, it should be L. flaviventris (Lawrence) or L. euleriflaviventris, depending on rank. If it remains in the genus Empidonax, the specific name should be bolivianus Allen.

Creation, management, and research on lakes and ponds at Patuxent Research Refuge Creation, management, and research on lakes and ponds at Patuxent Research Refuge
From 19391966, approximately 450 acres of impoundments were created for recreational and wildlife conservation purposes at Patuxent Research Refuge. Impoundments were of three major designs: impounded ravines, excavated basins, and impounded swamps. Over 50 species of wetland plants were transplanted to impoundments of Patuxent to determine best species for relatively infertile waters...

Zinc hazards to plants and animals with emphasis on fishery and wildlife resources Zinc hazards to plants and animals with emphasis on fishery and wildlife resources
Ecological and toxicological aspects of zinc in the environment are reviewed with emphasis on natural resources. Subtopics include sources and uses; chemical and biochemical properties; carcinogenicity, mutagenicity, teratogenicity; background concentrations in biological and nonbiological compartments; effects of zinc deficiency; toxic and sublethal effects on terrestrial plants and...

Late Paleocene and early Eocene calcareous nannofossils from three boreholes in an onshore-offshore transect from New Jersey to the Atlantic Continental Rise Late Paleocene and early Eocene calcareous nannofossils from three boreholes in an onshore-offshore transect from New Jersey to the Atlantic Continental Rise
Closely spaced, upper Paleocene and lower Eocene samples from three boreholes near Clayton, NJ, at Island Beach, NJ, and at Site 605 on the Atlantic Ocean continental rise were examined for their calcareous nannofossil content. This study documents calcareous nannofossil occurrences in Zones NP9 and NP10 and identifies biostratigraphically useful species, presents unexpected upbasin...

Modified level II streambed-scour analysis for structure I-70-60-5180 crossing Branch of McCracken Creek in Hendricks County, Indiana Modified level II streambed-scour analysis for structure I-70-60-5180 crossing Branch of McCracken Creek in Hendricks County, Indiana
Level II scour evaluations follow a process in which hydrologic, hydraulic, and sediment transport data are evaluated to calculate the depth of scour that may result when a given discharge is routed through a bridge opening. The results of the modified Level II analysis for structure 1-70-60-5180 on Interstate 70 crossing Branch of McCracken Creek in Hendricks County, Indiana, are...
