Abstract:
... Identifying key evolutionary strategies that support population persistence remains a challenging task for biodiversity conservation. Here we assess if animal adaptations to cope with low densities (i.e. that facilitate mate-findings or promote spatial aggregation of individuals) can allow species to persist in human-altered habitats. A spatially explicit and individual-based model was developed t ...

Abstract:
... Accurate prediction of chlorophyll a (Chl a) concentration in surface water bodies such as lakes or rivers is crucial for water quality management. This study improved the predictive simulation of instream Chl a with the Hydrological Simulation Program-FORTRAN (HSPF) by adding automatic calibration and modifying the growth-temperature formulation of phytoplankton in the original HSPF model.

Subject:
air; ecology; eggs; fish; larvae; migratory behavior; models; plants (botany); pollen; seed dispersal; seeds; spores; terminal velocity; wind
Abstract:
... Terrestrial plants seeds, spores and pollen are often dispersed by wind. Likewise, most eggs and larvae of marine organisms are dispersed by oceanic currents. It was historically believed that the spatial scale at which dispersal occurs was orders of magnitude smaller for plants than for fish. However, recent empirical estimates of seed and larval dispersal suggest that these dispersal scales are ...

Abstract:
... Ecological niche modelling helps us to understand the spatial assembly of species in heterogeneous environments. Three patterns have been widely reported in the research literature regarding the relationship between realised niches and macronutrient concentration gradients: (1) species’ optima are unevenly distributed, with a higher frequency in mesic conditions; (2) species’ response curves are n ...

Abstract:
... In recent years, the use of ecological niche models (ENMs) and species distribution models (SDMs) to explore the patterns and processes behind observed distribution of species has experienced an explosive growth. Although the use of these methods has been less common and more recent in marine ecosystems than in a terrestrial context, they have shown significant increases in use and applications. H ...

Abstract:
... Challenges associated with developing species distribution models (SDMs) with high-resolution data (including from lidar) prompted our investigation into a complementary approach to enhance the performance of SDMs using spatial data with different resolutions. In our experiment we developed a model with Maxent (a presence-background SDM) with variables that had a 30-m resolution, and then used the ...

Abstract:
... With increasing concern over the environment in mariculture, the integrated culture has received extensive attention in recent years. For management of aquaculture farms, a biophysical model was developed to quantify the potential influence of bivalves-seaweed integrated culture on pelagic ecosystem. We developed NEMURO.CULTURE model by coupling the cultivated species (kelp Laminaria japonica, oys ...

Abstract:
... Herd formation in animal populations, for example to escape a predator or coordinate feeding, is a widespread phenomenon. Understanding which interactions between individual animals are important for generating such emergent self-organisation has been a key focus of ecological and mathematical research. Here we show the relationship between the algorithmic rules of herd-forming agents, and the mat ...

Abstract:
... The Everglades, located in South Florida, USA, have been accumulating organic soils (peats) for 5000 years. The northern portion of the natural Everglades, called the Everglades Agricultural Area (EAA), has been drained for more than 100 years and has experienced soil subsidence since then. Rates of soil subsidence in the EAA have changed over time, due mostly to changes in land use and water mana ...

Abstract:
... The spatial and temporal patterns of broad front bird migration are governed by the geospatial distributions of landmasses, mountain ranges, and weather conditions. These distributions interact with the birds' innate program during migration and are critical to successful migration. Hence, favourable environmental conditions for migration consequently lead to spatio-temporal concentrations, and th ...

Abstract:
... Development of integrated population models (IPMs) assume the absence of systematic bias in monitoring programs, yet many potential sources of systematic bias in monitoring data exist (e.g., under-counts of abundance). By integrating multiple sources of data, we can assess whether various sources of monitoring data provide consistent inferences about changes in population size and, thus, whether m ...
