Texto completoLichstein, Jeremy William. Landscape effects on breeding songbird abundance in managed southern Appalachian forests. Chair of advisory committee: Theodore R. Simons.Many studies have demonstrated adverse effects of forest fragmentation on breeding forest songbirds in North America, and the viability of regional populations is thought to depend on large, unfragmented forests. However, we know relatively little about the landscape scale consequences of management in the forested landscapes that are presumed to be important to maintaining songbird metapopulations. The southern Appalachians, a mostly forested region, contains the largest network of public lands in the eastern U.S. Most of these public lands are managed by the U.S. Forest Service. To begin to understand the landscape scale effects of forest management in the southern Appalachians, I examined the relationship between the relative abundance of different species of breeding songbirds and local and landscape scale habitat variables in two predominately mid- to late-successional National Forests in the southern Appalachian Mountains, USA: the French Broad Ranger District of Pisgah National Forest (North Carolina) and the Nolichucky Ranger District of Cherokee National Forest (Tennessee). As part of the study, I explored two statistical problems frequently encountered in species-environment analysis: count data and spatial autocorrelation. Results from classical normal-errors regression models were similar to results from Poisson and negative binomial models that explicitly model counts. Normal-errors regression models were then modified to account for spatial autocorrelation using a conditional gaussian autoregressive model. Most species, especially Neotropical migrants, were significantly correlated with at least one landscape variable. These correlations included both landscape composition (i.e., the proportion of different landcover types) and landscape pattern (i.e., the spatial arrangement of landcover types) variables at 500 m to 2 km landscape scales. However, these landscape effects explained only a small fraction of the variation in bird relative abundance, and most species appear to respond primarily to elevation and local habitat factors in my study area. My results are consistent with other studies that have reported only weak to moderate landscape effects on songbird abundance in large managed forests. These results should not be interpreted as being inconsistent with results from studies in highly fragmented forests that have reported strong effects of patch size, patch isolation, and landscape scale forest cover on breeding songbirds.

Texto completoVillain, Avelyne. "Acoustic communication in female songbirds : functions, flexibility and plasticity in calls". Thesis, Lyon, 2016. http://www.theses.fr/2016LYSES069/document.
Texto completoThe theory of sexual selection has drastically oriented research on acoustic communication in birds: males learn and sing conspicuous songs and females choose. Consequently, (1) female vocal production has been neglected, (2) birdcalls (most bird social communication) have been understudied. Birdcalls were supposed to be non-learned and no effect of the environment was expected on their structure (no flexibility, no learning). I thus focused my thesis on vocal flexibility (short-term) and vocal plasticity (developmental) of female vocalizations (mainly calls). I studied two contexts in which both sexes produce vocalizations: intrapair communication at the nest and parent-offspring communication. Do pairs express vocal flexibility in their calls in response to environmental noise? Is call development influenced by social environment? I studied two species: the white-throated dippers, Cinclus cinclus. (in which both sexes produce calls and songs) and the zebra finch, Taeniopygia guttata, (in which only males sing but both sexes use the same calls). I showed in both species, that in response to environmental noise, pairs increased the amplitude of their calls or song notes. In dippers, spectral flexibility was observed in song notes but not in calls. However, zebra finch calls showed spectral flexibility in response to noise. Both sexes showed similar changes in their calls: call spectral flexibility is not sex specific. Last, I showed that the structure of male begging calls changed in response to the early social environment, bringing evidence of early vocal plasticity in males. No change was found in females, showing that they either differ in their plasticity abilities or do not express plasticity because they receive different social feedbacks. My work showed that females and males show vocal flexibility but their vocal developmental trajectories may differ. Calls are thus good study objects to investigate sexual dimorphism in vocal behaviour

Unlike the human brain, which produces few neurons in adulthood, the brains of songbirds continue to produce new neurons throughout life. The function of these new neurons is not know, although it has been suggested that they endow the avian brain with a remarkable regenerative capacity that does not exist in mammals. It has also been proposed that the addition of new neurons in adulthood underlies behavioral plasticity, such as song learning. A better understanding of the cellular mechanisms that control the addition of new neurons to the postnatal brain may help clarify its biological function. This thesis is an investigation of the cell biology of postnatal neurogenesis in the songbird forebrain, with special emphasis on the High Vocal Center. Neuronal progenitors in the juvenile zebra finch brain were identified by fate mapping using engineered retroviruses. Multiple populations of neural progenitors appear to exist in the juvenile zebra finch brain, and each produces different types of neurons. At least three cell types appear to be added to the postnatal finch brain. Homology between neurogenesis in the postnatal finch and embryonic mammalian forebrain was also assessed. To characterize the mechanism of cell addition, videos were made, documenting the migration and integration of new neurons into the High Vocal Center. Neural progenitors were labeled using retroviruses, carrying the gene for the green fluorescent protein, allowing new neurons to be observed in the intact brain, with a powerful infrared laser. By replacing a small hole in the skull with a piece of optical glass, one could observe labeled neurons periodically over many days as they were born until they wired up to the existing circuitry. New neurons engaged in a previously undescribed form of migration. Further study of this form of neuron migration as well as other aspects of postnatal neurogenesis may lead to the development of strategies for replacing neurons in the human brain lost to death or disease.

Grasslands are among the most rapidly declining ecosystems in the world. The Flint Hills ecoregion contains one of the largest remaining tracts of tallgrass prairie, but most of the area is managed with high densities of grazing animals and frequent prescribed burns, thereby reducing variation in vegetative structure. A homogeneous landscape leads to lower diversity and abundance of wildlife species, including grassland songbirds. Patch-burn grazing management has been proposed to more closely match the historical interaction between fire and selective grazing by native ungulates. Pastures managed with patch-burn grazing have a greater variety of vegetative structure and plant species composition, and as a result, higher species diversity, abundance, and reproductive success of grassland birds. However, past work has not considered potential effects of regional variation in predation risk and rates of brood parasitism by Brown-headed Cowbirds (Molothrus ater), or annual variation in climatic conditions on the effects of patch-burn grazing management on the reproductive success of grassland songbirds. Over a six year period and at two tallgrass prairie sites, I tested the effects of patch-burn grazing on the reproductive success of three native grassland songbird species, Dickcissels (Spiza americana), Eastern Meadowlarks (Sturnella magna), and Grasshopper Sparrows (Ammodramus savannarum), as well as subsequent effects on the space use, movements, and survival of fledgling Dickcissels. I found only minor effects of patch-burn grazing on the reproductive success of grassland songbirds, supporting previous studies that show that patch-burn grazing does not have negative effects on demographic rates of grassland songbirds. Management regime did not affect densities or territory size of male Dickcissels, but bird densities tended to be higher and territories tended to be smaller on patches within the patch-burn grazing treatment that were burned in the previous year. Thus, patch-burn grazing management might benefit Dickcissel populations by providing higher quality breeding habitat in unburned patches. Last, I found evidence for a potential tradeoff between habitat selection for nests vs. fledglings of Dickcissels in some rangeland management strategies. Parents that realized high reproductive success by nesting in pastures with lower cowbird densities, produced fledglings that faced high rates of depredation by snakes and showed greater movements away from those pastures. Survival rates and movements of Dickcissel fledglings were low, especially during the first week after leaving the nest, which stresses the importance of local habitat conditions. At a larger spatial scale, I tested whether regional differences in habitat structure could drive variation in apparent survival of grassland songbirds. I found that grassland- and shrubland-breeding species had higher estimates of apparent survival than forest-breeding species, contrary to the prevailing viewpoint that birds breeding in dynamic landscapes, such as frequently burned grasslands, should show lower apparent survival than species that breed in woody habitats. The results of my field study show that restoring the historical interaction between fire and grazing on the landscape via patch-burn grazing management could benefit grassland songbirds. Moreover, my dissertation is the first study that tests the effects of patch-burn grazing management on the survival and movements of fledgling Dickcissels, and shows that high cowbird densities can cause a tradeoff between different life-stages. Future conservation efforts should take into account regional variation in species abundance, predator community composition and abundance of Brown-headed Cowbirds when assessing the effects of rangeland management on the demography of grassland songbirds.

Complex motor behaviors in humans, such as speech, are not innate, but instead are learned. How does the brain construct neural circuits that generate these motor behaviors during learning? To understand the neural mechanisms underlying learned motor skills, I use vocal learning in songbirds as a model. While previous studies have shown that a premotor area in the songbird brain, HVC, is important for stereotyped adult song, the role of HVC in juvenile song is less known. This thesis characterizes how activity in HVC develops during song learning in juvenile birds. Early in song learning, temporal structure emerged in HVC. During the earliest vocalization of juvenile birds (subsong), HVC neurons exhibit bursts of action potentials. However, only half of the neurons show bursts that are temporally aligned to syllables, and most of these bursts are clustered around onsets of subsong syllables. Over several days, as the bird starts producing the earliest stereotyped vocalization called protosyllables, HVC neurons start exhibiting rhythmic bursts at 5-10 Hz. These rhythmic bursts are aligned to protosyllables, and bursts from different neurons are active at different latencies relative to protosyllables. Thus, as a population, HVC neurons start forming a rhythmic neural sequence. As the bird matures, multiple distinct syllable types emerge from a protosyllable. During this process, some neurons are active only during a specific syllable type ('specific neurons') while others are active during both syllable types ('shared neurons'). These shared neurons are active at similar latencies for both syllable types, and therefore form a shared neural sequence. Over development, fraction of shared neurons decrease and more neurons become specific. These results demonstrate that splitting of a neural sequence into multiple sequences underlies the emergence of a multiple syllable types. Moreover, this sequence splitting is observed during different song learning strategies, suggesting that this is a fundamental neural mechanism for song learning. This work demonstrates how the growth of a rhythmic neural sequence and its subsequence splitting gives rise to complex vocalization in songbirds. This may be a general neural mechanism in which the brain constructs neural circuits during learning of a complex motor behavior.

The basal ganglia form the largest sub-cortical structure in the human brain and are implicated in numerous human diseases. In songbirds, as in mammals, basal ganglia-forebrain circuits are necessary for the learning and production of complex motor behaviors; however, the precise role of this circuitry remains unknown. This thesis is an investigation into how the anterior forebrain pathway (AFP), an avian basal ganglia-forebrain circuit, supports vocal learning in the songbird. This investigation reveals two previously undiscovered functions of the AFP - both related to reinforcement, or trial-and-error, learning. One necessary component of reinforcement learning is the generation of variable behavior. The songs of learning juvenile birds are naturally highly variable. Rapid pharmacological inactivation of the AFP output nucleus causes an immediate and dramatic reduction in this variability. In addition, the first single-unit recordings of AFP output neurons in singing juvenile birds reveal little correlation with plastic song and a premotor correlation with the most variable form of singing, subsong. These results suggest a novel function for basal ganglia-forebrain circuitry in the production of exploratory behavior. A second component of reinforcement learning is the evaluation of performance-based feedback - auditory feedback in the case of singing. Conditional disruptive auditory feedback is a novel behavioral paradigm capable of causing rapid experimentally-controlled vocal learning. Inactivating the AFP while using this new paradigm to induce learning reveals that the AFP biases motor output to improve auditory feedback. This result suggests that basal gangliaforebrain circuits are involved in the evaluation of performance-based feedback. It also suggests for the first time that these circuits are capable of producing temporally precise premotor drive that incrementally improves a motor skill. In summary, this investigation significantly furthers the view that basal ganglia-forebrain circuitry is involved in reinforcement learning. It ascribes two functions to the anterior forebrain pathway: to drive variable behavior; and to bias future behavior incrementally towards better performance. By analogy, basal ganglia-thalamocortical loops may perform similar functions in mammals.

An infant reaches out for her new toy, struggling day after day to simply grasp her fingers around it. A few years later, she hits a tennis serve, perfect in the timing of its intricately choreographed movements. How does a young brain learn to use the muscles it controls, to properly coordinate motor gestures into complex behavioral sequences? To a surprising extent, for many advanced vertebrate behaviors this knowledge is neither innately programmed nor acquired via deterministic developmental rules, but must be learned through trial-and-error exploration. This thesis is an investigation of the neural mechanisms that underlie the production and maturation of one exploratory behavior - the babbling, or subsong, of a juvenile zebra finch. Using lesions and inactivations of brain areas in the song system, I identified neural circuits involved in the production of subsong. Remarkably, subsong did not require the high vocal center (HVC) - a premotor structure long known as the key region for controlling singing in adult birds - but did require the lateral magnocellular nucleus of the nidopallium (LMAN) - the output region of basal ganglia-forebrain circuitry previously considered a modulatory area. Recordings in LMAN during subsong revealed premotor activity related to the vocal output on a fast timescale. These results show, for the first time, the existence of a specialized circuit for driving exploratory motor control, distinct from the one that produces the adult behavior. The existence of two neural pathways for singing has raised the question of how motor control is transferred from one pathway to another and, in particular, how the control of song timing develops in these pathways. I found that early singing can be decomposed into mechanistically distinct "modes" of syllable and silent gap timing - randomly-timed modes that are LMAN-dependent and developmentally-acquired, consistently-timed modes that are HVCdependent. Combining acoustic analysis with respiratory measurements, I found that the consistently-timed mode in gap durations is formed by brief inspiratory pressure pulses, indicating an early involvement of HVC in coordinating singing with respiration. Using mild localized cooling - a manipulation that slows down biophysical processes in a targeted brain area - I found that the circuit dynamics intrinsic to HVC and LMAN are actively involved in controlling the timescales of distinct behavioral modes. In summary, this work demonstrates the existence of two motor circuits in the song system. These circuits are specialized for the generation of distinct types of neural dynamics - random exploratory dynamics, which are dominant early in life, and stereotyped sequential dynamics, which become dominant during development. Characterization of behaviorally-relevant dynamics produced by neural circuits may be a general framework for understanding motor control and learning.
