The conservation field is experiencing a rapid increase in the amount, variety, and quality of spatial data that can help us understand species movement landscape connectivity patterns. As interest grows more dynamic representations potential, modelers are often limited by capacity their analytic tools to handle these datasets. Technology developments software high-performance computing rapidly emerging many fields, but uptake within may lag, as our or choice language constrain ability keep pace. We recently updated Circuitscape, widely used analysis tool developed Brad McRae Viral Shah, implementing it Julia, language. In this initial re-code (Circuitscape 5.0) later updates, we improved computational efficiency parallelism, achieving major speed improvements, enabling assessments across larger extents with higher resolution data. Here, reflect on benefits strengthening collaborations computer scientists, extract examples from collection 572 Circuitscape applications illustrate how through decade repeated investment software, have been many, varied, increasingly dynamic. Beyond empowering continued innovations connectivity, expect faster run times will play an important role facilitating co-production stakeholders, increasing likelihood science be incorporated land use decisions.

Habitat islands can be defined as distinct patches of habitat surrounded by less contrasting matrix types. In contrast to true island biogeography (traditionally the study water), there have been efforts synthesize myriad studies that published, particularly syntheses cover full range By building on previous work, I aim provide a review in order blueprint for future research islands, including both naturally and anthropogenically fragmented systems. The is organized into three main parts. First, differences between are summarized. Second, theoretical frameworks currently used analyze systems reviewed. Third, findings focused various biological patterns synthesized. Drawing this synthesis, put forward two points regarding improving our understanding biogeography: first, increasing integration properties (including variation across space time) biogeographic models and, second, testing for, implications of, potential prevalence mass effects source-sink dynamics

Ecological sustainability has recently risen to prominence in scientific research and management applications. Approaches measuring ecological connectivity their application optimize network (EN) design are powerful tools against landscape fragmentation biodiversity loss. We focused on building an EN by identifying the most sensitive areas for within Reggio Calabria (Italy) metropolitan area. also proposed a defragmentation scenario improve obtained EN.

Spatial capture-recapture models (SCRs) provide an integrative statistical tool for analyzing animal movement and population patterns. Although incorporating home range formation with a theoretical basis of into SCRs can improve the prediction space use in heterogeneous landscape, this approach is challenging owing to sparseness recapture events. In study, we developed advection-diffusion model (ADCR), which extension formalism, providing new framework estimate density landscape permeability. tested unbiasedness estimator using simulated data generated by step selection function. We also compared accuracy estimates shapes those from SCR least-cost path basic SCR. addition, ADCR was applied real dataset Asiatic black bear (Ursus thibetanus) Japan demonstrate capacity detect geographical barriers that constrain movements.

Dispersal of individuals contributes to long-term population persistence, yet requires a sufficient degree landscape connectivity. To date, connectivity has mainly been investigated using least-cost analysis and circuit theory, two methods that make assumptions are hardly applicable dispersal. While these can be relaxed by explicitly simulating dispersal trajectories across the landscape, unified approach for such simulations is lacking.Here, we propose apply simple three-step simulate assess empirical GPS movement data set habitat covariates.In step one proposed approach, use integrated step-selection functions fit mechanistic model describing preferences dispersing individuals. In two, parameterized study area. three, derive three complementary maps; heatmap highlighting frequently traversed areas, betweenness map pinpointing corridors, inter-patch indicating presence intensity functional links between patches. We demonstrate applicability in case which collected on African wild dogs (Lycaon pictus) inhabiting northern Botswana.Using successfully parametrized detailed described individuals' preferences, as well potential interactions among two. The substantially outperformed omitted enabled us 80,000 area.By trajectories, our not only fewer unrealistic about dispersal, but also permits calculation multiple metrics together provide comprehensive view study, derived maps revealed several dog hotspots corridors extent Each highlighted different aspect connectivity, thus emphasizing their nature. Overall, demonstrates simulation-based offers powerful alternative traditional modeling techniques.

Maintaining and restoring ecological connectivity is considered a global imperative to help reverse the decline of biodiversity. To be successful, practitioners need guided by modeling research that rigorous reliable for task at hand. However, methods workflows within this rapidly growing field are diverse few have been carefully scrutinized. We propose four steps should consistently undertaken in studies order improve rigour utility: 1) describe type being modeled, 2) assess uncertainty sensitivity model parameters, 3) validate outputs, ideally with independent data 4) make non‐sensitive raw code openly available enhance computational reproducibility. reviewed literature determine extent which included these steps. focused on generated novel landscape outputs using circuit theory restricted our assessment concerning terrestrial mammals. Among 181 meeting search criteria, 39% communicated 18% conducted some form or analysis (or both), attempted their only 7% used fully do so. Lastly, 13% made all available, 2% provided required two both. Our findings highlight clear opportunity reliability, reproducibility utility research. provide checklist researchers can consult include outputs. This will more informed decisions ensure limited resources conservation restoration allocated appropriately.
