“…Medir y modelar la conectividad teniendo como enfoque especies sombrilla de la región resulta ventajoso para la planificación del territorio de la Orinoquía, ya que se convierte en una guía para el desarrollo de acciones de gestión más específicas que respondan a la ecología e historia natural de las especies (Kirk, et al, 2023). Estos deben evaluarse con métodos que sean fáciles de reproducir con el fin de lograr definir a futuro la efectividad del diseño e implementación de las estrategias propuestas para los corredores.…”

“…Para representar la conectividad ecológica de un amplio rango de especies de fauna en un territorio resulta útil enfocarse en especies sombrilla, es decir, aquellas que requieren grandes extensiones de tierra para subsistir de manera natural y que permiten la conservación del ecosistema al cual se asocian (Isasi-Catalá, 2011) (Kirk, et al, 2023). Con base en la anterior premisa, se seleccionaron cuatro (4) especies de grandes y medianos mamíferos representativos de la Orinoquía, los cuales fueron seleccionados para los departamentos de Casanare y Arauca a partir del criterio de expertos de la región: Tapirus terrestris (danta de tierras bajas), Alouatta seniculus (mono aullador), Panthera onca (jaguar) y Pteronura brasiliensis (nutria gigante de río o perro de agua).…”

Los procesos de degradación y fragmentación de los ecosistemas naturales generados a partir de la transformación de la Orinoquía colombiana han alterado la matriz del paisaje, afectando las poblaciones de fauna como consecuencia de la disminución y aislamiento de sus hábitats. Por lo anterior, se propone el diseño de corredores ecológicos para especies de mamíferos como una herramienta de manejo de paisaje para la priorización de áreas de importancia ambiental. Para la elaboración de los corredores se empleó la metodología de rutas de mínimo costo a partir del análisis de resistencia del paisaje y criterios de evaluación mediante el cual se definió el home range para cuatro especies sombrilla. Como resultado se generaron ocho corredores para Tapirus terrestris, Alouatta seniculus, Panthera onca y Pteronura brasiliensis, con los cuales se fomenta la conectividad estructural del paisaje entre áreas de interés ambiental y áreas del Sistema Nacional de Áreas Protegidas (SINAP) en los departamentos de Casanare y Arauca.

Section: Selection Of Habitat Connectivity Metricsmentioning

“…The most robust measures of functional connectivity (e.g., effective mesh size for City Biodiversity Index, see Deslauriers et al 2018) quantify the potential of a given landscape to provide unfragmented or unobstructed habitat for particular wildlife by spatially mapping habitat and barriers to movement (Deslauriers et al 2018;Kirk et al 2023). To be informative for such measures, metrics that define taxon-specific habitat connectivity need to be both ecologically meaningful and translate into spatial data layers that are location-specific and readily available (Kirk et al 2023). We selected 30 metrics to represent landscape-scale, functional habitat connectivity for our seven taxon groups (Table 2) that were ecologically important (Doerr et al 2010; and had the potential to provide the spatial data inputs to underpin robust measures of functional connectivity (Kirk et al 2018;.…”

“…The 'City Biodiversity Index' -a Convention on Biological Diversity endorsed tool to monitor urban biodiversity -measures ecological connectivity as the relationship between the total area of habitat available and the degree to which it is functionally (dis)connected, either by distance (e.g., small birds will be unable to disperse where distance between tree cover exceeds their movement capacity (Tremblay and St. Clair 2009)) or by physical or behavioural barriers to movement (Chan et al 2014;Deslauriers et al 2017;Kirk et al 2018Kirk et al , 2023. While recent studies have highlighted the value of using this approach for spatially mapping and measuring habitat connectivity in BSUD (e.g., Kirk et al 2018Kirk et al , 2021, the input data often remains coarse in terms of what constitutes habitat (e.g., presence of trees only without consideration of preferred spacing and composition), and taxonspecific movement thresholds and movement barriers (Kirk et al 2023). Applying BSUD to achieve ecological connectivity outcomes requires a greater taxon-specific understanding of what constitutes functional connected habitat to underpin these connectivity maps, models, and measures.…”

Urban planning which enhances native biodiversity in and around cities is needed to address the impacts of urbanisation and conserve urban biodiversity. The “Biodiversity Sensitive Urban Design” (BSUD) framework incorporates ecological knowledge into urban planning to achieve positive biodiversity outcomes through improved urban design and infrastructure development. BSUD includes principles to direct strategic design and placement of connected wildlife habitat. However, effective BSUD implementation requires defining and quantifying the landscape-scale habitat connectivity needs of a range of taxon groups within urban contexts. The aim of our study was to use expert elicitation to address these gaps in landscape-scale habitat connectivity currently limiting the capacity of urban planning. We estimated habitat connectivity needs for seven representative taxon groups in urban environments, including ideal habitat, habitat constraints, barriers to movement, and movement thresholds that determine habitat connectivity. In using expert elicitation to quantify habitat connectivity requirements for urban biodiversity, our study provides insights on both the usefulness of expert elicitation to inform urban habitat connectivity planning generally, and the functional habitat connectivity requirements of our focal taxon groups specifically. Overall, we consider our expert-derived estimates of connected habitat to be a highly useful set of baseline data for habitat and connectivity modelling and urban planning for a range of taxon groups.

Floral resources encourage colonisation and use of green roofs by invertebrates

et al. 2023

Green roof retrofits offer a promising avenue to increase greenspace and thus biodiversity in the city. The successful colonisation and establishment of plants and animals on green roofs is limited by the location and context of the green roof. Here we use a before, after, control, impact (BACI) design to monitor the colonisation of a new retrofit roof in Melbourne CBD. We find that colonisation for some taxa occurs rapidly, with honeybees (Apis mellifera) arriving four days after flowers had been planted. Other insect taxa, such as native bees, did not colonise the impact roof but were present on the green roof reference site, which was lower in height and planted with native plants. Invertebrate abundance increased for all sites after the retrofit was built, however this sampling period was in late spring when more insects are expected to be active. Bird richness and abundance didn’t change in response to roof greening, but invertebrate richness was significantly higher on reference sites and increased after the green roof retrofit was built for the impact site. There was an apparent ‘spill over’ effect onto the nearby green roof control, which also increased in invertebrate diversity. Overall, invertebrate composition across roof types was driven by floral density. Floral density and richness increased on the impact roof as vegetation matured, subsequently correlating with higher abundance and richness of invertebrates. We use these findings to discuss colonisation of green roofs and argue for strategic placement of new green roof retrofits to maximise their biodiversity potential.
