“…In comparison, Garcia () estimated the daily nest survival rate for an eastern population of Painted Buntings to be 0.895. Our estimate is similar to daily nest survival rates reported for other shrub‐nesting species (Knutson et al , Streby and Miles , Rodewald et al ). Based on our estimates of daily survival rate and probability of survival, breeding productivity of Painted Buntings is likely sufficient to support the study population unless post‐fledging or adult mortality is unusually high.…”

Declines in populations of Painted Buntings (Passerina ciris) over the past several decades have led to their recent classification as a species of conservation concern. To better assess their status, we investigated factors associated with productivity and abundance of a population in south-central Louisiana during 2010-2011. We monitored 41 Painted Bunting nests, 14 with video cameras, to identify predators, parasitism events, and improve nest success estimates. Vegetation measurements were also collected at nest sites and non-nest sites to quantify habitat characteristics. We used an information-theoretic approach to evaluate support for multiple models evaluating nest success. Highly supported models indicated large negative effects of Brown-headed Cowbird (Molothrus ater) parasitism, and positive effects of increased canopy cover and distance to habitat edge on daily survival rates. Our estimate of daily survival rate was 0.94 ± 0.03 and the probability of survival was 0.25 ± 0.02. Point-count data revealed that densities of Painted Buntings were greater in treeline habitats than in open scrub-shrub and mature forest edge habitats. Furthermore, treelines had higher densities of large trees (>23 cm dbh) and percent canopy cover, variables positively associated with nest success, than open scrub-shrub and forest edge habitats. In general, survival rates and causes of nest failure in southern Louisiana were similar to those determined for breeding populations of Painted Buntings at other sites. Our results suggest that treelines, despite having a high edge-to-area ratio, might be preferred nesting habitat for Painted Buntings in our study area. RESUMEN. Efecto de borde y de las características del lugar de anidamiento en eléxito reproductivo de Passerina cirisDescensos poblacionales del Gorrión Pintado (Passerina ciris), durante lasúltimas décadas, ha llevado a que la especie se considere una de preocupación. Para buscar la forma más apropiada de determinar su estatus, investigamos los factores asociados a la productividad y abundancia de una población en la parte sur-central de Luisiana, durante el 2010-2011. Monitoreamos, con cámaras de video, 41 nidos de el ave para identificar depredadores, parasitismo reproductivo y mejorar los estimados deléxito de anidamiento. Se tomaron datos sobre la vegetación en los lugares de construcción de nidos y lugares no utilizados para cuantificar las características del hábitat. Utilizamos un enfoque de información teórica para evaluar el apoyo de múltiples modelos aléxito de anidamiento. Los modelos con mayor apoyo indicaron efectos negativos del parasitismo reproductivo por parte del Tordo Pardo (Molothrus ater), y efecto positivo, en la supervivencia diaria, de un incremento en la cobertura del dosel y distancia al borde del hábitat. Nuestro estimado de sobrevivencia diaria fue de 0.94 ± 0.03 y la probabilidad de sobrevivir fue 0.25 ± 0.02. Conteos de punto revelaron que la densidad del gorrión era mayor en hábitat de líneas deárboles que en matorrales abiertos y bordes d...

“…We encourage researchers to publish their results when possible so that data can be discovered and analyzed by interested researchers. That desire was the motivation behind this special issue and publication of other nesting success data from the fire-fire surrogate study [17,18]. Alternatively, data can be archived in repositories such as the Avian Knowledge Network.…”

Longleaf pine (Pinus palustris) forest ecosystems evolved with short-interval, low intensity fires. Fire suppression has reduced or eliminated fire and has caused extensive changes in plant community composition and structure. The National Fire and Fire-Surrogate study was implemented to evaluate effects of alternative habitat treatments, such as herbicide application and mechanical thinning, and to compare them with effects of prescribed fire. We evaluated how treatments influenced the nesting success of birds breeding in 10-ha plots of longleaf pine at Solon Dixon Experimental Forest, Alabama. We measured daily rates of nest mortality for 432 nests of 33 species in unmanipulated (controls), burned, herbicide-treated and burned, thinned, and thinned and burned plots during the three years of our study. Although we accumulated observations of 6,624 days that nests were exposed to possible predation, sample sizes were still too small to permit robust statistical analyses of treatment effects. Data from one (Eastern Towhee, Pipilo erythrophthalmus) of two species with the largest sample sizes suggested that nests in treatment plots experienced higher rates of mortality than did nests in control plots, but sample sizes were still small enough that high estimates of variance prevented strong statistical evaluation. Nest survival for the other common species, Northern Cardinal (Cardinalis cardinalis), showed no such suggestive differences. We present results from all nests of all species for which we found three or more nests so that future researchers can use the data during meta-analyses. We also encourage those designing future similar studies to consider expanding the size of study plots so that at least the most numerous open-cup nesting birds can be found in sufficient numbers for strong statistical analyses. In longleaf pine forests of southern Alabama, we estimate that minimum plot sizes would need to be 50 ha for the two most common species, Eastern Towhee and Northern Cardinal.

“…In southern pine forests, bird abundance and richness were positively related to volume of coarse woody debris and density of snags (Jones et al, 2009). In Midwestern oak-hickory forests, thinning harvest and prescribed fire increased avian nest survival (Streby and Miles, 2010). However, responses to variable retention harvests are species specific and temporally dynamic: Response of some species is immediate but shortlived, whereas other species exhibit a deferred (maybe several years post-treatment) but longlasting response (Hagar andFriesen, 2009, Twedt andSomershoe, 2009).…”

Preface that in a situation of commercial dependency, some contractors use their power over the SME to interfere in the management of their business, thereby curtailing their decisional autonomy. It is concluded that, businesses which find themselves in a situation where they have to obey the orders of a contractor may have limited resources to innovate or develop new and promising niche markets.Chapter five highlights the perspective on membership and ownership in a private forest owner cooperative in a Swedish private forest owner cooperative. It looks at the mismatch between goal of the cooperative and that of the members, to illustrate how the members, the inspectors and the managers look upon the private forest owner in terms of identity, benefits, and agreement. It is suggested that improvements can be achieved by applying a new institutional way of organization, which will make it easier to create a meaningful communication. Chapter six evaluates the economic feasibility of an eucalyptus agroforestry system in Brazil. It is noted that in decision making between projects which have different time horizons, the Equivalent Periodic Benefits (BPE) method has priority over the Net Present Value (VPL). Since each different age of eucalyptus represents an alternative project with different planning horizons, the alternative with a greater BPE must be chosen.Chapter seven analyses the effects of a unilateral tariff liberalisation on forestry products in Australia, amongst the leading exporters and importers of forest products, in particular, as well as global merchandise, in general. The Global Trade Analysis Project (GTAP) model and its database, version 7 with 2004 data are utilized. Given that forest products only comprise a small proportion of world merchandise trade, it is expected that trade liberalisation would cause small changes in terms of trade, real GDP, production, consumption and prices of forest products in most countries. Chapter eight is dedicated to strategic cost management practices adopted by segments of Brazilian agribusiness. It focus on investigating the use, perceived benefits and difficulties in implementation by agribusiness companies of strategic cost management practices, treated in the literature as the most appropriate ones to help managers in the management process of organizations. The findings of this exploratory study provide the foundation for conducting further research in the form of multiple case studies and cross-case analyses.Chapter nine is about forestry and life cycle assessment (LCA). LCA helps in measuring environmental aspects and potential impacts of a product through its entire life-cycle from raw material acquisition (beginning of the life-cycle) to manufacturing, use, recycling, re-use and final disposal (end of the product's life-cycle). Though LCA is particularly difficult in forestry due to the long rotation period, it remains a good tool especially today when there is increased awareness of environmentally friendly technologies, renewable energy and eco-effici...
