Balancing Model Complexity, Data Requirements, and Management Objectives in Developing Ecological Reference Points for Atlantic Menhaden

Katie Drew, Matthew Cieri, Amy M. Schueller, Andre Buchheister, David Chagaris, Geneviève Nesslage, Jason E. McNamee, James H. Uphoff
2021 Frontiers in Marine Science  
These approaches ranged in complexity, from models with minimal data requirements and few assumptions to approaches with extensive data needs and detailed assumptions.  ...  More complex models required a wider array of data and were more difficult to update within the current management time-frames, but produced a more useful framework for managers.  ...  We thank the members of the ASMFC Menhaden Technical Committee and the ERP WG for the data they provided and their contributions to the discussions around model development.  ...

The landscape ecological approach in bird conservation: integrating the metapopulation concept into spatial planning

PAUL OPDAM, RUUD FOPPEN, RIEN REIJNEN, ALEX SCHOTMAN
2008 Ibis  
On the basis of empirical data, statistical and metapopulation models are being developed to be used to evaluate spatial planning scenarios and to support decision making about which scenario is closest  ...  The conclusion is that, depending on the spatial scale, landscape fragmentation is a threat to birds.  ...  Habitat quality variables are measured and used as basic variables in the analysis. Examples for birds are reviewed in Opdam (1991).  ...

2004 Behavioral Ecology and Sociobiology  
This is neglected using simple enumeration procedures, but is taken into account when repertoire size is estimated by appropriate capture-recapture models adjusted for species-specific song organization  ...  On the other hand, in species with small repertoire size and homogenous syllable usage, enumerations may be satisfactory.  ...  Slater for their useful comments. K. Riebel kindly provided data on the chaffinch.  ...

2016 Ecology  
The patterns with body size were confirmed for all species groups by a comparison with IUCN data on the proportion of extant threatened species: the models correctly predicted a multimodal distribution  ...  with body size for carnivorous birds and a monotonic distribution for mammals and non-carnivorous birds.  ...  AcknowledgMents This research project was funded by the European Commission under the Seventh Framework Programme on Environment, ENV.2012.6.3-3: DESIRE -DEvelopment of a System of Indicators for a Resource  ...

Assessing the impacts of grazing levels on bird density in woodland habitat: a Bayesian approach using expert opinion

Petra M. Kuhnert, Tara G. Martin, Kerrie Mengersen, Hugh P. Possingham
2005 Environmetrics  
Many studies on birds focus on the collection of data through an experimental design, suitable for investigation in a classical analysis of variance (ANOVA) framework.  ...  The first is a conditional approach, sometimes referred to as a twocomponent approach that models the presence or absence of a species using logistic regression and then, conditional on presence, abundance  ...  We also thank David Lindenmayer and Alan Welsh, who kindly provided us with their Leadbeater Possum dataset, which we used to test our models.  ...

Do birds of a feather flock together? Empirical evidence from the Generalized Approach to Tourist Ethnocentrism (GATE)

Hermann Kimo Boukamba (PhD student)
2020 African Journal of Hospitality, Tourism and Leisure  
Psychometric properties as well as model-fit, robustness, and measurement invariance of the composite were confirmed.  ...  Beyond the scope of the home country's economy, the present study investigates the effects of ethnocentrism on the cognitive, affective and conative image of a destination, in view of perceptions of cultural  ...  Data processing and analysis The nature and suitability of the data were assessed to support the choices of statistical analysis tools and methods.  ...

No More Birds and Bees: A Process Approach to Parent-Child Sexual Communication

A. Tina Coffelt, N. Loreen Olson
2014 Annals of the International Communication Association  
Information is revealed in little bits and pieces over the course of a child's development. Privacy boundary permeability opens, and the circumference of privacy boundaries expands over time.  ...  In this chapter, we present conjoined models of parent-child sexual communication.  ...  The models depict sexual information as emerging from multiple parent-child conversations about sex over time and offer contra-evidence to the static birds-and-the-bees, onetime conversation.  ...

Using a Sound Field to Reduce the Risks of Bird-Strike: An Experimental Approach

John P. Swaddle, Nicole M. Ingrassia
2017 Integrative and Comparative Biology  
One reason for bird-strike may be that birds fail to pay adequate attention to the space directly in front of them when in level, cruising flight.  ...  In addition to slowing down, birds increased the angle of attack of their body and tail, potentially allowing for more maneuverable flight.  ...  Acknowledgments We thank Rachel Ellick for assistance with animal care and Dan Cristol and Matthias Leu for advice on the design and interpretation of this study.  ...

Clélia Sirami, Lluis Brotons, Ian Burfield, Jocelyn Fonderflick, Jean-Louis Martin
2008 Biological Conservation  
The analysis revealed a nested pattern in the effect of species attributes.  ...  Our results strongly support the hypothesis that large-scale habitat changes associated mainly with land abandonment are impacting bird community patterns in the Mediterranean region.  ...  Acknowledgements We thank everyone cited in Table 1 for agreeing to let us use their original datasets. We thank Miquel Caceres for developing the niche breadth index.  ...

Studies of birds and reptiles have provided many basic insights into the neuroendocrine control of reproductive processes.  ...  Puberty refers to the physiological processes by which an individual attains sexual maturity and is thus able to reproduce successfully as an adult.  ...  Acknowledgments The authors would like to thank BK Follett and J. Balthazart for discussion and access to unpublished data. GFB's work on seasonal breeding is supported by NINDS (R01 NS 35467).  ...
