Abstract. In multi-species communities the stability of a system is difficult to assess from field observations. This is the case for example for competitive interactions in plant communities. If a mathematical model can be formulated that underlies the processes in the community, a community matrix can be constructed whose elements represent the effects of each species onto every other (and itself) at equilibrium. The most common competition model is the Lotka-Volterra equation set. It contains interspecific competition coefficients to represent the interactions between species. In plant community ecology several attempts have been made to quantify competitive interactions and to assemble a community matrix, so far with limited success. In this paper we discuss a method to use pairwise interaction coefficients from experimental plant communities to analyse feasibility and stability of multi-species sets. The approach is contrasted with that of Wilson and Roxburgh (1992) and is illustrated using data from Roxburgh and Wilson (2000a). Results from Wilson and from this study differ (some times substantially), with our approach being more pessimistic about stability and coexistence in plant communities.

Scientists must sometimes choose between competing definitions of key terms. The degree to which different definitions facilitate important discoveries should ultimately guide decisions about which terms to accept. In the short run, rules of thumb can help. One such rule is to regard with suspicion any definition that turns a seemingly important empirical matter into an a priori exercise. Several prominent definitions of ecological “stability” are suspect, according to this rule. After evaluating alternatives, I suggest that the faulty definitions resulted from an overemphasis on population dynamics in community ecology. Machine metaphors of nature may have given rise to a related problem of experimental design.

Les communautés d'êtres vivants peuvent elles êtres considérées comme des organismes complexes, ou au contraire comme de simples groupes d'espèces, individuelles ? Cette question est à l'origine de nombreux débats en écologie, ces deux visions impliquant notamment des prédictions très différentes dans les patrons spatiaux et temporels de communautés. Lorsque l'environnement change graduellement dans l'espace ou dans le temps, la vision individualiste implique des changements graduels dans la composition des communautés, tandis que la vision du "super-organisme" prédit des changements davantage abrupts. L'objectif principal de cette thèse est de comprendre et déterminer sous quelles conditions ces différents types de réponse des communautés aux changements de l'environnement peuvent advenir. Dans une première partie, nous étudions le rôle que la compétition inter-spécifique peut jouer dans l'émergence de différents patrons spatiaux de communautés. Nous étudions notamment les conditions théoriques sous lesquelles la compétition peut faire apparaître des patrons graduels ou discontinus dans la composition des espèces. Dans une deuxième partie, nous étudions l'influence des interactions entre les espèces et leur environnement sur les patrons spatiaux de communautés. Nous montrons notamment comment des phénomènes de construction de niche peuvent mener à l'émergence de changements brutaux dans la composition des communautés, mais également dans les conditions de l'environnement. Enfin, dans une dernière partie, nous illustrons le rôle que peut jouer la biodiversité dans la protection des écosystèmes face à des effondrements écologiques, et notamment le rôle que peut jouer la biomasse dans cette protection
The question whether communities should be viewed as superorganisms or loose collections of individual species has been the subject of a long-standing debate in ecology. Each view implies different spatial and temporal community patterns. When environment gradually changes in space or in time, the organismic view predicts that species turnover is discontinuous, while the individualistic view predicts gradual changes in species composition. The main objective of this thesis is to understand the theoretical conditions under which these various types of community response can occur. First, I study the role of interspecific competition can play in the emergence of various spatial community patterns. I investigate the theoretical conditions in competition under which smooth or discrete spatial patterns can emerge. Then, I study how interactions between species and their environment can lead to various community patterns in space. I notably show how ecological niche construction can lead to the emergence of abrupt changes in species composition and in the environment, and the role biodiversity plays therein. Finally, I focus on the role biodiversity can play against ecosystem collapse. In this section, I illustrate how diversity loss, through its effects on total biomass, can lead to ecosystem collapse

Measuring the impact of physical disturbance on macrofaunal communities and sediment composition is important given the increased demand for the exploitation and disturbance of marine ecosystems. The aim of the present investigation was to provide a comprehensive study about the extent to which the disturbance (especially aggregate dredging) may affect benthic ecosystem function. The first part of the thesis concerns a field investigation of the impacts of dredging on the benthic community and related ecosystem function which was measured by different approaches including traditional methods based on benthic community structure and a more novel approach based on the functional traits of benthic organisms. The assessment was done by comparing dredged sites (Area 222, southeast England) with nearby undisturbed reference sites from the years 2001 to 2004 and in 2007. In general, low dredging intensity did not appear to impose great impacts on the benthic community and related ecosystem function compared to the higher intensity activity. Most of the analyses suggested that the community at the high dredging intensity site had yet to recover at the end of this study period. Among many factors related to the recovery of the benthic community was sediment composition where gravel deposits appeared to support a faster biological recovery. Meanwhile, the recovery of species with specific traits, such as tube-building and filter feeding also indicate a faster recovery for the whole community. The experimental work to determine different impacts of Hediste diversicolor on its surrounding depending on its relative size is discussed in Appendix 1.

El ensamblaje, estructuración y funcionamiento de las comunidades naturales, compuestas de muchas especies que forman redes complejas de interacciones ecológicas, ha desconcertado a los ecólogos durante muchas generaciones. Investigación ecológica pionera determinó que el tamaño de la comunidad y su complejidad (medida como la conectividad en la red de interacciones ecológicas) limita la estabilidad de la comunidad, y por lo tanto impiden que las comunidades sean indefinidamente complejas o ricas en especies. Investigación sobre el ensamblaje y la estabilidad en comunidades naturales ha descubierto que la arquitectura de la red trófica es la clave para la estabilidad de la comunidad y su persistencia. Así, los científicos comenzaron a centrarse en la comprensión de las complejas redes de interacciones entre especies, y pronto se dieron cuenta de que la dinámica de las poblaciones de las comunidades naturales se rigen por la estructura de estas redes. Por otra parte, ciertas características observadas en la estructura de las redes ecológicas son responsables del mantenimiento de la estabilidad en diferentes tipos de comunidades ecológicas. El siguiente paso en la investigación de las redes ecológicas es incorporar varios tipos de interacción en un escenario ecológico más amplio. Esto incrementará el conocimiento de la estructura y la estabilidad de la comunidad. El cambio global está afectando los ecosistemas de todo el mundo, con profundos impactos sobre el delicado equilibrio de la naturaleza. Ya ha causado un número sin precedentes de extinciones, y el consiguiente daño en la estructura y funcionamiento del ecosistema ha llevado a muchos a sugerir que en estos momentos estamos presenciando la sexta extinción masiva en la historia de la Tierra. El principal desafío para la investigación ecológica que tenemos por delante es entender y predecir cómo el cambio global está afectando, y es probable que afecte en el futuro, los ecosistemas complejos. En esta tesis enfrento este desafío utilizando una aproximación empírico-­‐teórica integradora para explorar los efectos del cambio global -­‐cambio climático, pérdida de biodiversidad e invasión de especies-­‐ en comunidades compuestas por múltiples especies. Adicionalmente, investigo qué hace que las comunidades ecológicas sean estables durante su ensamblaje, y cómo esta estabilidad puede verse afectada por el cambio global. En concreto, he empleado una combinación de revisión de resultados y análisis de datos empíricos, un novedoso marco conceptual para el análisis de las relaciones entre diferentes dimensiones de la estabilidad ecológica, modelos teóricos fundamentados en redes tróficas con estructuras realista y ecuaciones diferenciales ordinarias para simular la dinámica de las poblaciones, y modelos espacialmente explícitos basados en el individuo con una mezcla de tipos de interacciones ecológicas; con el fin de obtener una visión predictiva de los efectos de los diferentes componentes del cambio global sobre las comunidades naturales y sobre los factores que explican la estabilidad de estos conjuntos de especies. Algunos de mis principales hallazgos son: (1) cambios de distribuciones de especies provocados por el cambio climático están generando comunidades nuevas . Estas últimas se caracterizan por nuevos patrones en que las distribuciones de tamaño corporal dentro de las redes tróficas se están desplazando hacia tamaños más pequeños, las interacciones especialistas se están perdiendo, y las fuerzas de interacción son cada vez más fuertes en general, con consecuencias importantes para la dinámica de la comunidad. (2) Las diferentes dimensiones de la estabilidad ecológica se correlacionan de manera no trivial. La pérdida de biodiversidad lleva a un desacoplamiento de estas correlaciones. Esto conduce a dinámicas altamente impredecibles en comunidades ecológicas sujetas a perturbaciones. (3) Enfocándonos en las invasiones biológicas vemos que la estructura de la red trófica es un factor determinante para éxito de la invasión. Comunidades menos conectadas, más modulares, y más heterogéneas en términos de amplitud de la dieta de las especies que las componen son más robustas a las invasiones biológicas. Las invasiones hacen a las comunidades más conectadas y menos modulares en general, lo que las hace aún más frágiles a las invasiones. Algunos rasgos de las especies invasoras, como su tamaño corporal y su capacidad de capturar la presa, también son fuertes determinantes del éxito de la invasión. (4) Por último, las interacciones mutualistas incrementan tanto la estabilidad temporal como la estabilidad espacial, mediante el mantenimiento de una agregación espacial más constante. Las distribuciones de las fuerzas de interacción en la red se desplazan hacia valores más bajos a medida que la fracción de mutualismos en la comunidad aumenta.
The assembly, structuring and functioning of natural communities, composed of many species forming complex networks of ecological interactions, has puzzled ecologists for many generations. Early ecological research determined that community size and complexity (measured as connectivity in the network of ecological interactions) limit community stability, and hence impose constraints to communities to become indefinitely complex or speciose. Community assembly and stability research uncovered the fact that food web architecture is the key to community stability and persistence. Scientists thus started to focus on the understanding of complex networks of interactions between species, and it was soon realised that species population dynamics are influenced by biotic interactions within the overall network. Moreover, certain features observed in the structure of ecological networks are responsible for the maintenance of stability and species persistence in different kinds of ecological communities. The next step in ecological networks research is to incorporate several interaction types into a broader ecological scenario. This will further our knowledge in community structure and stability. Global change is affecting all ecosystems across the globe, having profound impacts over the delicate balance of nature. It has already caused an unprecedented number of extinctions, and the consequent damage to ecosystem structure and functioning has prompted many to suggest that we are currently witnessing the sixth mass extinction in the history of the Earth. The main big challenge for ecological research that lies ahead is to understand and predict how different components of global change are affecting and will likely affect complex ecosystems. In this thesis I tackle this challenge following an integrative empirical-­‐theoretical approximation exploring the effects of global change –climatic warming, biodiversity loss and species invasion-­‐ on multispecies communities. In addition, I investigate what makes ecological communities stable through their assembly, and how this stability may be affected by global change. Specifically, I employed a combination of empirical results review and data analysis, a novel conceptual framework for the analysis of relationships between different dimensions of stability, theoretical models grounded on realistic food web structure and ordinary differential equations to simulate populations dynamics, and individual-­‐based spatially explicit models with a mixture of ecological interaction types in order to gain predictive insights on the effects of different components of global change on natural communities and several factors behind the stability of these assemblages of species. Some of my key findings are: (1) Species range shifts triggered by climate change are generating novel communities. These are characterized by consistent novel patterns where body size distributions within the food webs are getting shifted towards smaller sizes, specialised interactions are getting lost, and interaction strengths are getting stronger in general, with further consequences for community dynamics. (2) Different dimensions of ecological stability are correlated in non-­‐trivial ways. Biodiversity loss leads to a decoupling of the correlations previously observed between stability measures. This leads to highly unpredictable dynamics of ecological communities after major disturbances. (3) When focusing on biological invasions I find that food web structure is a strong determinant of invasion success. Less connected, more modular, and more heterogeneous communities in terms of diet breadth are more robust to biological invasions. Invasions make communities more connected and less modular in general, rendering them even more fragile to invasions. Species traits of the invasive species, such as body size and the ability to capture prey, are also strong determinants of invasion success. (4) Finally, mutualistic interactions increase both temporal stability and spatial stability, by keeping spatial aggregation more constant. Distributions of interaction strengths across the entire food web are shifted towards lower values as mutualism increases.

Les forêts tropicales sont confrontées à des perturbations anthropiques fréquentes et intenses, telles que l'exploitation sélective - l'abattage de quelques arbres dans des forêts anciennes, tandis que le reste du peuplement se régénère naturellement. De nombreuses études ont été menées sur la reconstitution des stocks de carbone et de bois, en raison d'un intérêt pour l'atténuation du changement climatique et la rentabilité de l'exploitation. Malgré le rôle crucial de la biodiversité pour le maintien et le fonctionnement des écosystèmes - et sa valeur intrinsèque - peu d'études ont été menées sur l'impact de l'exploitation sélective sur la biodiversité. Par conséquent, cette thèse vise à caractériser la réponse de la diversité et de la composition des arbres à l'exploitation forestière dans les forêts tropicales américaines.Grâce aux inventaires forestiers (1986-2021, diamètre à hauteur de poitrine ≥ 10 cm) de la station de Paracou (Guyane française), nous avons construit un cadre bayésien de modélisation des trajectoires de la diversité et de la composition des arbres après exploitation : Paracou a été perturbé par des traitements sylvicoles de différentes intensités en 1986-1987. Nous avons propagé l'incertitude associée à la détermination botanique et aux mesures des traits fonctionnels, et modélisé les trajectoires de diversité et de composition taxonomique, phylogénétique et fonctionnelle des arbres au niveau de l'espèce, par rapport à leurs niveaux pré-perturbation. En outre, nous avons évalué l'effet des caractéristiques des communautés d'arbres pré-perturbation, des conditions biophysiques et des propriétés de la perturbation sur nos trajectoires d'attributs forestiers. Deuxièmement, nous avons utilisé une version simplifiée du cadre de modélisation susmentionné sur des inventaires forestiers à long terme provenant de parcelles situées au Costa Rica et dans trois pays amazoniens (Observatorio de los Ecosistemas Forestales de Costa Rica et Tropical managed Forest Observatory). Nous avons modélisé leurs trajectoires de diversité et de composition taxonomique et fonctionnelle après exploitation au niveau du genre, à partir desquelles nous avons extrait des indicateurs sur la période d'inventaire de chaque site. Nous avons ensuite évalué l'effet de la structure de la communauté d'arbres pré-perturbation et des propriétés de la perturbation sur ces indicateurs. Bien que plus variables dans la seconde étude ayant une portée géographique plus large, nous avons observé des tendances similaires dans les deux études : la diversité a majoritairement augmenté après exploitation et les communautés d'arbres sont principalement passées de stratégies de conservation à des stratégies d'acquisition des ressources. Ces changements semblent provenir du recrutement abondant et momentané d'espèces de début de succession présentant des caractéristiques d'acquisition des ressources, ce qui leur confère un avantage compétitif lorsque l'intensité de perturbation - i.e., disponibilité de la lumière et de l'espace - augmente. En effet, les changements de diversité et composition ont augmenté dans les deux études avec l'intensité de perturbation, alors que les autres descripteurs n'ont pas eu d'effet significatif. Troisièmement, suite à l'importance de l'intensité de perturbation dans les études précédentes, nous avons développé un cadre commun de modélisation des trajectoires de forêts perturbées à travers un gradient d'intensité de perturbation. Nous avons testé notre approche de modélisation sur des inventaires forestiers de long-terme du Costa Rica et de Guyane française, après exploitation sélective, agriculture, et coupe à blanc suivie d'un feu.Ces résultats ouvrent des perspectives sur les méthodes d'évaluation de la réponse forestière aux perturbations, la réponse des forêts elle-même et ses processus écologiques sous-jacents, et l'intérêt des forêts perturbées pour les plans de gestion et de conservation forestières
Tropical forests face more frequent and intense anthropogenic disturbances, such as selective logging, namely the felling and harvesting of a few commercially valuable trees in old-growth forests, while the remaining stand is left for natural regeneration. Many studies focused on this regeneration, particularly on the recovery of carbon and timber stocks, most likely due to a strong interest in climate change mitigation and logging profitability. However, despite the crucial role of biodiversity for ecosystem maintenance and functioning - and its intrinsic value - there have been few studies on the impact of selective logging on biodiversity. Therefore, this thesis - organised in three studies - aimed at characterising the response of tree diversity and composition to logging in tropical American forests.First, we drew upon the long-term forest inventories (1986-2021, trees with a diameter at breast height ≥ 10 cm) from Paracou experimental station to build a Bayesian modelling framework of tree diversity and composition trajectories after selective logging. Paracou is located in French Guiana and was disturbed by silvicultural treatments of different intensities in 1986-1987. We propagated in our Bayesian framework the uncertainty associated with botanical determination and functional trait measurements, and modelled Paracou trajectories of taxonomic, phylogenetic and functional tree diversity and composition at the species level, relatively to their pre-disturbance levels. Additionally, we assessed the effect of pre-disturbance tree community characteristics, biophysical conditions and disturbance properties on our forest attribute trajectories. Second, we used a simplified version of the aforementioned Bayesian modelling framework on long-term forest inventories from sample plots located in Costa Rica and three Amazonian countries (respectively belonging to the Observatorio de los Ecosistemas Forestales de Costa Rica and the Tropical managed Forest Observatory). We modelled their post-logging trajectories of taxonomic and functional tree diversity and composition at the genus level, from which we extracted indicators solely over the inventory timespan of each site. We then assessed the effect of pre-disturbance tree community structure and disturbance properties on such indicators. While more variable in the second study with a broader geographical scope than in the first one, we observed similar trends in both studies: diversity mostly increased after logging and tree communities mainly shifted from resource-conservative strategies to resource-acquisitive strategies. Such changes appeared to be driven by the abundant and transient recruitment of early-successional species with acquisitive trait values, which provided them with a competitive advantage as disturbance intensity - i.e., light and space availability - increased. Indeed, changes in diversity and composition increased in both studies with disturbance intensity whereas disturbance selectivity, pre-disturbance tree community characteristics and biophysical conditions had no significant effect. Third, building up on the paramount importance of disturbance intensity in the two previous studies, we developed an original Bayesian hierarchical model of recovery trajectories, considering disturbed forests in a common framework, through a disturbance intensity gradient. We tested our modelling approach on data from two long-term experiments in Costa Rica and French Guiana, set up after selective logging, agriculture, and clearcutting and fire.Overall, these results opened various perspectives on the methods used to evaluate forest response to disturbance, the forest response itself and the ecological processes underlying forest succession, and how disturbed forests could be considered in forest management and conservation plans

Annotation:
This project was designed to examine the stability of stream ecosystems in response to forest disturbance and subsequent succession. Stability was defined as the ability of streams to retain particulate organic matter and nutrients during storms. I hypothesized that forest streams are least stable during the intermediate stages of forest succession because particulate organic matter accumulations in streams are lowest at that time. This hypothesis was tested by examining stream stability in relation to forest succession. Stream surveys indicated fewer debris dams and organic matter accumulations in streams draining early and intermediate successional forests compared to reference sites. The abundance of large wood declined within 10 years of forest disturbance and continued to decline for at least 30-40 years through the intermediate stages of forest succession. Comparisons of inputs with standing stocks of organic matter indicated that streams draining early and intermediate successional sites receive less litter from their watersheds and processed it faster. Decreases in stream obstructions combined with changes in litter inputs and processing resulted in relatively high storm transport of fine organic matter from disturbed streams. Storm organic matter export from disturbed streams averaged 4.22 g AFDW/m² and from reference streams averaged 1.83 g AFDW/m². Storm nutrient budgets, constructed by measuring nutrient inputs (soil water, throughfall) and outputs (stream discharge) during individual storms indicated that streams draining early and intermediate successional forest were less retentive of nitrogen and phosphorus than reference sites. Nitrogen loss from disturbed streams averaged 58.04 mg/m²/storm and from reference streams averaged 16.52 mg/m²/storm. Phosphorus loss from disturbed streams averaged 32.52 mg/m²/storm and from reference sites averaged 7.14 mg/m²/storm. A majority of the nitrogen and phosphorus loss was in association with organic particles. There was no difference between disturbed and reference streams in potassium, calcium, or sulfate retention during storms. However, disturbed streams tended to lose more particulate organic potassium and calcium than reference sites. These results indicate that forest disturbance has a Iong-term impact on stream ecosystems by reducing their stability for many years following forest clearing.

Annotation:
Rhizoferrin, a siderophore produced by Rhizopus arrhizus, has been shown in previous studies to be an outstanding Fe carrier to plants. However, calculations based on stability constants and thermodynamic equilibrium lead to contradicting conclusions. In this study a kinetic approach was employed to elucidate this apparent contradiction and to determine the behavior of rhizoferrin under conditions representing soil and nutrient solutions. Stability of Fe3+ complexes in nutrient solution, rate of metal exchange with Ca, and rate of Fe extraction by the free ligand were monitored for rhizoferrin and other chelating agents by 55Fe labeling. Ferric complexes of rhizoferrin, desferri-ferrioxamine-B (DFOB), and ethylenediamine-di(o-hydroxyphenylacetic acid) (EDDHA) were found to be stable in nutrient solution at pH 7.5 for 31 days, while ferric complexes of ethylenediaminetetraacetic acid (EDTA) and mugineic acid (MA) lost 50% of the chelated Fe within 2 days. Fe-Ca exchange in Ca solutions at pH 8.7 revealed rhizoferrin to hold Fe at non-equilibrium state for 3-4 weeks at 3.3 mM Ca and for longer periods at lower Ca concentrations. EDTA lost the ferric ion at a faster rate under the same conditions. Fe extraction from freshly prepared Fe-hydroxide at pH 8.7 and with 3.2 mM Ca was slow and followed the order. DFOB > EDDHA > MA > rhizoferrin > EDTA. Based on these results we suggest that a kinetic rather than equilibrium approach should be the basis for predictions of Fe-chelates efficiency. We conclude that the non-equilibrium state of rhizoferrin is of crucial importance for its behavior as a Fe carrier to plants.

Annotation:
The HIP framework aims to guide higher education (HE) teachers and researchers to reconsider and reflect on how to rethink HE pedagogy in new and different ways. It builds on insights from the report Hacking Innovative Pedagogy: Innovation and Digitisation to Rewild Higher Education. A Commented Atlas (Beskorsa, et al., 2023) and incorporates the spirit of rewilding and hacking pedagogies to inspire new professional communities focused on innovating digital education. The framework considers and guides the development of teachers’ digital pedagogy competences through an inclusive bottom-up approach that gives space for individual teacher’s agency while also ensuring a collective teaching culture. The framework emphasizes how pedagogical approaches can address the different needs that HE teachers and student communities have that reflect disciplines cultures and/or the diversity of learners. Only a framework mindful of heterogeneity will be able to address questions of justice and fair access to education. Likewise, in the spirit of rewilding, the framework should not be considered a static “one size fits all” solution. We aim for an organic and dynamic framework that may be used to pause and reflect to then turn back to one’s own teaching community to consider (learn from, listen to and respond to the teaching and learning of different communities). Therefore we plan that this framework will be a living document throughout the HIP-project’s lifetime.
