Reproductive biology and nest success of cerulean warblers in IndianaJones, Kelly C. January 2006 (has links)
Within the Pleasant Run Unit of the Hoosier National Forest, Morgan-Monroe State Forest, and Yellowwood State Forest in Indiana, a total of 45 Cerulean Warbler territories were mapped during 2004 and 2005. We sampled vegetative characteristics of the Cerulean Warbler territories and 45 random plots in southern Indiana, as part of a description of Cerulean Warbler habitat usage in this part of their breeding range. Cerulean Warbler song-perch trees were larger and taller than surrounding trees within territories. In addition, certain species were selected as song-perch trees, whereas others were avoided. Territories were characterized by fewer mid-sized trees (11.6-14.9 m tall), and a higher mean canopy height. In addition to tree size, tree species may play an important role in territory site selection of Cerulean Warblers in southern Indiana. Relative abundance, reproductive success, territory sizes, and observations of nest material thievery are also reported. / Department of Biology

Does timber harvesting affect Cerulean warbler foraging ecology?MacNeil, Margaret M. 10 May 2012 (has links)
We determined foraging characteristics of Cerulean Warblers (Dendroica cerulea) in Morgan-Monroe and Yellowwood state forests in southern Indiana from 2007-2009. The average foraging height, tree height, and tree diameter at breast height (dbh) were greater for males than females. During 2008, areas of our study site received silvicultural manipulations that allowed us to compare foraging behavior before and after treatments. Harvesting techniques included shelterwood and clearcut or single and group tree selection. Foraging Cerulean Warblers in harvested areas had a lower average foraging height, tree height, and dbh during post-treatment than in pre-treatment years. Additionally, we examined foraging tree species selection and determined expected foraging tree species use based on basal area and stem density of tree species in the territories. We compared territory composition to random sites to explore tree selection on a larger scale. The most commonly used foraging tree species were bitternut hickory (Carya cordiformis), white oak (Quercus alba), and tulip tree (Liriodendron tulipifera). / Department of Biology

Cerulean warbler population and breeding response to recent silviculture and influences of prey availability on avian nesting ecologyWagner, Jennifer R. 05 May 2012 (has links)
This study presents the results of a field study comparing the effects of two forest harvest methods on the Cerulean Warbler, a state-endangered songbird. Population
estimates and a breeding study produced no significant differences among groups, although the species was not attracted to forest openings and experienced decreased nest
success in treated sites. Additional study on prey influences showed strong correlations with timing of breeding and peak larval lepidopteran abundance, specifically on oak and hickory tree species. Data suggests that these trees are vital to increased probability of
nest success due to an increase in prey availability within territories. Further study is recommended to ascertain the long-term effects of forest harvest and the importance of
oak and hickory dominated landscapes to the persistence of this species. / Cerulean warbler population response and nesting success in forests with recent silviculture -- Avian nesting ecology and prey abundance using frass drop as an indicator. / Department of Biology

Efeito protetor do 1,8 cineol na pancreatite aguda induzida por ceruleÃna em camundongos / Protective effect of 1.8 cineol in acute pancreatitis induced in mice ceruleinPatricia Rodrigues Lima 25 April 2013 (has links)
MinistÃre de l'Enseignement SupÃrieur et de la Recherche / Pancreatite aguda (PA) à uma doenÃa inflamatÃria em que mediadores prÃ-inflamatÃrios, estresse oxidativo e sinalizaÃÃo de NF- kB desempenham um papel fundamental. O 1,8-cineol, um monoterpeno presente em diversas espÃcies vegetais, à conhecido por seu potencial antioxidante e anti-inflamatÃrio. Para verificar a sua eficÃcia na prevenÃÃo da PA, este estudo avaliou o 1,8-cineol (100, 200 e 400 mg / kg, v.o) na PA induzida por ceruleÃna (50 Âg / kg / h à 5, i.p.) em camundongos Swiss. O 1,8-cineol foi administrado uma hora antes da primeira injeÃÃo de ceruleÃna. Grupos tratados com veÃculo ou talidomida foram incluÃdos como controles. Seis horas depois, as amostras de sangue foram coletadas para determinar os nÃveis sÃricos de amilase, lipase e citocinas. O pÃncreas foi removido para exame morfolÃgico, ensaios de mieloperoxidase (MPO) e malondialdeÃdo (MDA), alteraÃÃes na glutationa reduzida (GSH) e para a imunocoloraÃÃo do fator nuclear NF-κB. O pulmÃo direito foi removido para ensaio de MPO. O 1,8-cineol reduziu o dano histolÃgico e a expressÃo de NF-κB induzidos por ceruleÃna. CeruleÃna aumentou significativamente a amilase, lipase, TNF-α, IL1-β e IL-6 e reduziu IL-10. O 1,8-cineol 100, 200 e 400 mg/kg reverteu significativamente os danos causados pela ceruleÃna, atravÃs da reduÃÃo da amilase (14; 16; 21%), lipase (49; 48; 42%), TNF-α (46; 66; 44%), IL1-β (53; 45 e 67%) e IL-6 (49; 40; 41%) e aumento da IL-10 (34; 29 e 46%), respectivamente. CeruleÃna produziu edema pancreÃtico, aumentou MDA, MPO pancreÃtica, MPO pulmonar e reduziu GSH em comparaÃÃo com o grupo veÃculo (p ˂ 0,05). O 1,8-cineol 100, 200 e 400 mg/kg reduziu o edema pancreÃtico (6; 27; 17 %), MDA (34; 29; 46 %), MPO pancreÃtica (40; 55 e 78 %), MPO pulmonar (42; 45 e 22 %) e preservou GSH (62; 63 e 65 %). Estes achados sugerem que o 1,8-cineol pode prevenir a severidade da pancreatite aguda induzida por ceruleÃna em camundongos por meio de um mecanismo anti-inflamatÃrio e antioxidante. / Acute pancreatitis (AP) is an inflammatory condition in which pro-inflammatory mediators, oxidative stress and NF-kB signaling have a fundamental role. The 1,8-cineole, a monoterpene present in several plants species, is known for its antioxidant and anti-inflammatory potential. In order to verify its efficacy preventing AP, this study evaluated 1,8-cineole (100, 200 and 400 mg/kg, oral) on AP induced by cerulein (50 Âg / kg / h à 5, i.p.) in Swiss mice. The 1,8-cineole was administrated one hour before the first injection of cerulein. Groups treated with vehicle or thalidomide were included as controls. Six hours later, blood samples were collected to determine blood levels of amylase, lipase and cytokines. The pancreas was removed for morphological examination, myeloperoxidase (MPO) and malondialdehyde (MDA) trials, changes in reduced glutathione (GSH) and for immunostaining of nuclear factor NF-κB. The right lung was removed for MPO trial. The 1,8-cineole reduced the histological damage and the expression of NF-κB induced by cerulein. Cerulein increased significantly amylase, lipase, TNF- α, IL1- β and IL-6, reducing IL-10. The 1,8-cineole 100, 200 and 400 mg/kg reversed significantly the damages caused by cerulein by reducing amylase (14; 16; 21 %), lipase (49; 48; 42 %), TNF-α (46; 66; 44 %), IL1-β (53; 45 e 67 %) e IL-6 (49; 40; 41 %) and enhanced IL-10 (34; 29 e 46 %), respectively. Cerulein produced pancreatic edema, increased MDA, pancreatic MPO, pulmonary MPO and decreased GSH comparing to the vehicle group (p < 0,05). The 1,8 cineole 100, 200 and 400 mg/kg reduced pancreatic edema (6; 27; 17%), MDA (34; 29; 46%), pancreatic MPO (40; 55 and 78 %), pulmonary MPO (42; 45 and 22 %) and preserved GSH (62; 63 and 65 %). These findings suggest that 1,8-cineol can prevent the severity of cerulein-induced acute pancreatitis in mice through an anti-inflammatory and antioxidant mechanisms.

Population response of a declining songbird to silviculture : how cerulean warbler (Setophaga cerulea) territory size and settlement patterns fare in the face of forest disturbanceDibala, Ryan H. 22 May 2012 (has links)
Over the past five decades, populations of the Cerulean Warbler (Setophaga cerulea) have declined precipitously and the response of populations to silviculture has been identified as a high-priority research need. This species was studied in nine forest management units in Southern Indiana following a harvest that took place in 2008. Males were detected, territories were demarcated, and male age-class was determined to identify settlement patterns. Vegetation was measured in all territories and associated random non-use sites. Data analyzed in ArcMap (ArcGIS 10) show that Cerulean Warbler territory size was smallest and density was highest in even-aged units. Territories contained a greater number of small woody species than non-use sites but no vegetative differences existed between male age-classes. Instead, males appeared to select areas by relying on social cues from experienced neighbors. It is possible that “social attraction” management techniques could influence male Cerulean Warbler settlement patterns, providing a valuable tool for the conservation of this species. / Forest management effects on cerulean warbler territory size in southern Indiana -- Conspecific social cues strongly influence cerulean warbler male settlement patterns in a managed forest. / Department of Biology
