The AOU Conservation Committee Review of the biology, status, and management of Cape Sable Seaside Sparrows: Final report The AOU Conservation Committee Review of the biology, status, and management of Cape Sable Seaside Sparrows: Final report
The Cape Sable Seaside Sparrow (Ammodramus maritimus mirabilis) was listed as an original member of the federal list of endangered species in 1968. It is restricted to seasonally flooded prairies of extreme southern Florida and is disjunct from all other conspecific breeding populations (Kushlan et al 1982, McDonald 1988). Since the subspecies was described in 1919, its populations have...

Estuaries of the northeastern United States: Habitat and land use signatures Estuaries of the northeastern United States: Habitat and land use signatures
Geographic signatures are physical, chemical, biotic, and human-induced characteristics or processes that help define similar or unique features of estuaries along latitudinal or geographic gradients. Geomorphologically, estuaries of the northeastern U.S., from the Hudson River estuary and northward along the Gulf of Maine shoreline, are highly diverse because of a complex bedrock...

Regional effects of hydrologic alterations on riverine macrobiota in the New World: Tropical-temperate comparisons Regional effects of hydrologic alterations on riverine macrobiota in the New World: Tropical-temperate comparisons
This article has two main objectives: to examine what is known about regional effects of hydrologic modifications in temperate and tropical areas of the New World (i.e., North and South America and the Caribbean), with an emphasis on fishes and molluscs; and to discuss research needs regarding regional effects of hydrologic alterations in temperate and tropical regions. A better...

Species variation in osmotic, cryoprotectant, and cooling rate tolerance in poultry, eagle, and Peregrine Falcon spermatozoa Species variation in osmotic, cryoprotectant, and cooling rate tolerance in poultry, eagle, and Peregrine Falcon spermatozoa
Potential factors influencing spermatozoa survival to cryopreservation and thawing were analyzed across a range of the following avian species: domestic chicken (Gallus domesticus), domestic turkey (Meleagris gallopavo), golden eagle (Aquila chrysaetos), Bonelli’s eagle (Hieraaetus fasciatus), imperial eagle (Aquila adalberti), and peregrine falcon (Falco peregrinus). Studies focused on

Stratification based on reproductive state reveals contrasting patterns of age-related variation in demographic parameters in the kittiwake Stratification based on reproductive state reveals contrasting patterns of age-related variation in demographic parameters in the kittiwake
Heterogeneity in individual quality can be a major obstacle when interpreting age-specific variation in life-history traits. Heterogeneity is likely to lead to within-generation selection, and patterns observed at the population level may result from the combination of hidden patterns specific to subpopulations. Population-level patterns are not relevant to hypotheses concerning the...

Plant phenology in a cloud forest on the island of Maui, Hawaii Plant phenology in a cloud forest on the island of Maui, Hawaii
We recorded the times of flowering, fruiting, and leafing for ten native canopy and subcanopy trees and shrubs (monthly from December 1994 through December 1997) in a montane cloud forest with relatively aseasonal rainfall on the island of Maui, Hawaii. These species represented the great majority of individual woody plants at the site. Flowers and fruits were available in the community...

Effects of the mosquito larvicides temephos and methoprene on insect populations in experimental ponds Effects of the mosquito larvicides temephos and methoprene on insect populations in experimental ponds
The nontarget effects of Abate® 4E (44.6% temephos) at 0.054 kg of active ingredient (a.i.) per 1 ha and of Altosid® Liquid Larvicide (5% methoprene) at 0.011 kg a.i./ha were investigated in 18 experimental ponds (average area, 202 m2; maximum depth, 0.7 m) at Patuxent Wildlife Research Center, Laurel, Maryland, USA. Ponds were sprayed three times at 3-week intervals. Six ponds were...

Toxicity of manganese to Ceriodaphnia dubia and Hyalella azteca Toxicity of manganese to Ceriodaphnia dubia and Hyalella azteca
Manganese is a toxic element frequently overlooked when assessing toxicity of effluents, sediments, and pore waters. Manganese can be present at toxic levels in anoxic solutions due to increased solubility under chemically reducing conditions, and it can remain at those levels for days in aerated test waters due to slow precipitation kinetics. Ceriodaphnia dubia and Hyalella azteca are...
