A practical assay for TME has shown that TME estimates are less sensitive than AME to variation in food intake. The TME assay may be particularly useful in studies of natural foods that are difficult to obtain in quantities large enough to supply test birds with maintenance requirements.

By 2 years post-spray, vegetation on the treated site had recovered to near pre-spray status. No difference in density of the bird community was evident between treated and untreated sites during all years of study although individual species densities were modified. Several bird species decreased their use of shrub cover, and increased their use of deciduous trees 1 year after treatment. By 2 years post-spray, many species had returned to pre-spray use of most measured habitat components. Results indicated that application of glyphosate can modify the density and habitat use of birds.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Forest Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Morrison, M., and Meslow, E.C., 1984, Effects of the herbicide glyphosate on avian community structure in the Oregon coast range: Forest Science, v. 30, no. 1, p. 95-106.","productDescription":"95-106","startPage":"95","endPage":"106","numberOfPages":"12","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":193412,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":18310,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://saf.publisher.ingentaconnect.com/content/saf/fs/1984/00000030/00000001/art00016","linkFileType":{"id":5,"text":"html"}}],"volume":"30","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a27e4b07f02db6101d0","contributors":{"authors":[{"text":"Morrison, M.L.","contributorId":83624,"corporation":false,"usgs":true,"family":"Morrison","given":"M.L.","email":"","affiliations":[],"preferred":false,"id":335059,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Meslow, E.

One egg was taken per nest from as many as 20 nests per site during early incubation. The nests were marked and revisited after hatching, but before fledging, to record the number of live young. DDE was detected in all of the collected eggs (total 147) at a mean concentration of 3.1 ppm, fresh basis (residue means are geometric). Mean DDE at the seven sites varied from 1.8 to 7.6 ppm. Polychlorinated biphenyls (PCBs) were detected in 81 eggs (mean 1.0 ppm); the highest mean at any site was 2.2 ppm. Twelve other organochlorines were each detected in 1 to 30 eggs, usually at a concentration of &gt; 1.0 ppm. Mean total organochlorines in the eggs from the seven sites ranged from 2.0 to 10.1 ppm and the median number of compounds per egg ranged from one to five. Eggshell thickness was negatively correlated (p &gt; 0.001, r = – 0.585) with DDE levels in the 147 eggs. Average shell thickness (0.258 ± 0.030 mm) was 8.8% lower than the average thickness (0.283 ± 0.016mm) of 40 pre-DDT eggs from this region. The nesting sites with the highest DDE and total organochlorine residues in the eggs had the thinnest shells, produced the fewest young and had more nonviable eggs and dead young. At four of the seven sites, the average number of live young per nest was &gt; 2.0, the minimum long-term mean required for population maintenance.

Embryos oiled past the midpoint of the 28-day incubation period were insensitive to as much as 100 μl of petroleum. Fuel oil weathered outdoors for several weeks was as toxic as fresh oil to larid embryos. Productivity estimates obtained following various oil treatments indicated that only under severe conditions (e.g. large doses of petroleum contaminating young embryos) could egg oiling have a significant impact upon populations of the Herring Gull and species with similar life-history characteristics. Species that are more sensitive to oil, however, those having lower reproductive potentials and higher postfledging mortality rates or those subject to other stresses, may be more adversely affected by oil pollution.</span></p>","language":"English","publisher":"American Ornithological Society","doi":"10.1093/auk/101.3.584","usgsCitation":"Lewis, S., and Malecki, R., 1984, Effects of egg oiling on larid productivity and population dynamics: The Auk, v. 101, no. 3, p. 584-592, https://doi.org/10.1093/auk/101.3.584.","productDescription":"9 p.","startPage":"584","endPage":"592","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":193501,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"101","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a2fe4b07f02db615c97","contributors":{"authors":[{"text":"Lewis, S.J.","contributorId":50231,"corporation":false,"usgs":true,"family":"Lewis","given":"S.J.","affiliations":[],"preferred":false,"id":335088,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Malecki, R.A.","contributorId":70498,"corporation":false,"usgs":true,"family":"Malecki","given":"R.A.","affiliations":[],"preferred":false,"id":335089,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Treatment with EPN resulted in 22 to 44% mortality over this dose range by 18 days of development compared with 4 and 5% for untreated and vehicle-treated controls. EPN impaired embryonic growth and was highly teratogenic: 37–42% of the surviving embryos at 18 days were abnormal with cervical and axial scoliosis as well as severe edema. Brain weights were significantly lower in EPN-treated groups at different stages of development including hatchlings. Brain neurotoxic esterase (NTE) activity was inhibited by as much as 91% at 11 days, 81% at 18 days, and 79% in hatchlings. Examination of brain NTE activity during the course of normal development revealed an increase of nearly sixfold from Day 11 through hatching. The most rapid increase occurred between Day 20 and hatching. Brain acetylcholinesterase (AChE) activity was inhibited by as much as 41% at 11 days, 47% at 18 days, and 20% in hatchlings. Plasma cholinesterase and alkaline phosphatase activities were inhibited and plasma aspartate aminotransferase activity was increased at one or more stages of development. Hatchlings from EPN-treated eggs were weaker and slower to right themselves. Histopathological examination did not reveal demyelination and axonopathy of the spinal cord that was characteristic of delayed neurotoxicity in adult birds.</span></span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/0041-008X(84)90334-X","usgsCitation":"Hoffman, D.J., and Sileo, L., 1984, Neurotoxic and teratogenic effects of an organophosphorus insecticide (phenyl phosphonothioic acid-<i>O</i>-ethyl-<i>O</i>-[4-nitrophenyl] ester) on mallard development: Toxicology and Applied Pharmacology, v. 73, no. 2, p. 284-294, https://doi.org/10.1016/0041-008X(84)90334-X.","productDescription":"11 p.","startPage":"284","endPage":"294","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":193769,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"73","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4affe4b07f02db697a4e","contributors":{"authors":[{"text":"Hoffman, D.

Similar tests with ringed turtledoves (Streptopelia risoria) were conducted with five of the granular formulations to check for interspecific differences. The test chemicals were Amaze 15G (isofenphos), Counter 15G (terbufos), Dasanit 15G (fensulfothion), Diazinon 14G (diazinon), Di-Syston 15G (disulfoton), Dyfonate 20G (fonofos), Furadan 10G (carbofuran), Lorsban 15G (chlorpyrifos), Nemacur 15G (fenamiphos), Parathion 10G (parathion), Tattoo 10G (bendiocarb), Temik 15G (aldicarb), and Thimet 15G (phorate). Information is also presented on dose-response relations and their use in hazard assessment, granule size and hazard, response patterns, and toxic signs. The general conclusions were: (1) The organophosphates (fenamiphos and fensulfothion) and the carbamate (aldicarb) were the most toxic of the insecticides tested. (2) The granular formulation and its technical grade active ingredient were of equivalent toxicity, or the granular was significantly less toxic. (3) The dose-response curve enhances hazard assessment. (4) Ingestion of a single granule of Temik 15G was shown to be life threatening to bobwhite-sized birds, and ingestion of fewer than five granules could be lethal to sparrow-sized birds for Dasanit 15G, Diazinon 14G, Dyfonate 20G, Furadan 15G, and Nemacur 15G. (5) It is therefore suggested that the hazard associated with granular insecticides may be more dependent on which species (cf. size and feeding behavior) inhabit a treated area than on the actual application rate.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecotoxicology and Environmental Safety","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/0147-6513(84)90015-0","collaboration":"3024_Hill.pdf","usgsCitation":"Hill, E.F., and Camardese, M., 1984, Toxicity of anticholinesterase insecticides to birds: Technical grade versus granular formulations: Ecotoxicology and Environmental Safety, v. 8, no. 6, p. 551-563, https://doi.org/10.1016/0147-6513(84)90015-0.","productDescription":"551-563","startPage":"551","endPage":"563","numberOfPages":"13","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":194053,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":18253,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://dx.doi.org/10.1016/0147-6513(84)90015-0","linkFileType":{"id":5,"text":"html"}}],"volume":"8","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b01e4b07f02db698801","contributors":{"authors":[{"text":"Hill, E.

The small number of rejections suggests that there is little evidence of differences in band reporting rate by proximity to banding sites, geographic location, or over time. Thus, the best estimate of band reporting rate for black ducks is a constant 0.43. This estimate should be used with caution, because we believe that it overestimates reporting rate due to the unknown proportion of reward bands found that were not reported.</p>","language":"English","publisher":"Wiley","doi":"10.2307/3808450","usgsCitation":"Conroy, M., and Blandin, W., 1984, Geographic and temporal differences in band reporting rates for American black ducks: Journal of Wildlife Management, v. 48, no. 1, p. 23-36, https://doi.org/10.2307/3808450.","productDescription":"14 p.","startPage":"23","endPage":"36","numberOfPages":"14","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":195948,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"48","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1ce4b07f02db6a95fb","contributors":{"authors":[{"text":"Conroy, M.J.","contributorId":84690,"corporation":false,"usgs":true,"family":"Conroy","given":"M.J.","email":"","affiliations":[],"preferred":false,"id":335161,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Blandin, W.W.","contributorId":107811,"corporation":false,"usgs":true,"family":"Blandin","given":"W.W.","email":"","affiliations":[],"preferred":false,"id":335162,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The method is used to illustrate previously developed one-age-class band-recovery models, and is extended to new models, including the analysis with a covariate for survival rates and variable-time-period recovery models.  Extensions to R-age-class band- recovery, mark-recapture models, and twice-yearly marking are discussed.

When sufficient thickness and residue data are available for estimating critical values of DDE from the regression equation, the estimates are meaningful but are likely to be inflated because adverse effects unrelated to eggshell thinning such as parental behavior and embryotoxicity unrelated to eggshell deficiencies are not taken into account.....Establishing critical levels of pollutants in eggs and tissues is a necessary procedure in  assessing effects of these chemicals on individuals and populations of sensitive  species. There are inherent difficulties in quantifying the effects of any pollutant on population trends and declines in productivity. The sample egg technique is apparently a more sensitive method for estimating critical levels of DDE, but some subjective interpretation is required for results obtained by both methods.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wilson Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Blus, L.J., 1984, DDE in birds' eggs: Comparisons of two methods for estimating critical levels: The Wilson Bulletin, v. 96, no. 2, p. 268-276.","productDescription":"268-276","startPage":"268","endPage":"276","numberOfPages":"9","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":18196,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://elibrary.unm.edu/sora/Wilson/v096n02/p0268-p0276.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":196333,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"96","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4acce4b07f02db67e539","contributors":{"authors":[{"text":"Blus, L.
