| Publication date: 1 August 2019Source: Ecological Modelling, Volume 405Author(s): Oskar Kärcher, Karin Frank, Ariane Walz, Danijela MarkovicAbstractNiche-based species distribution models (SDMs) have become an essential tool in conservation and restoration planning. Given the current threats to freshwater biodiversity, it is of fundamental importance to address scale effects on the performance of niche-based SDMs of freshwater species’ distributions. The scale effects are addressed here in the context of hierarchical catchment ordering, considered as counterpart to coarsening grain-size... | ||

| Publication date: 1 August 2019Source: Ecological Modelling, Volume 405Author(s): Nathan R. De Jager, Molly Van Appledorn, Timothy J. Fox, Jason J. Rohweder, Lyle J. Guyon, Andrew R. Meier, Robert J. Cosgriff, Benjamin J. VandermydeAbstractSimulation models are often used to identify hydrologic regimes suitable for different riparian or floodplain tree species. However, most existing models pay little attention to forest successional processes or other disturbances that may interact with the hydrologic regime of river systems to alter forest dynamics in space and time. In this study, we... | ||

| ###RSS_DATE### | ||
| Publication date: 1 August 2019Source: Ecological Modelling, Volume 405Author(s): Amelie Schmolke, Steven M. Bartell, Colleen Roy, Nicholas Green, Nika Galic, Richard BrainAbstractThe Topeka shiner, a small cyprinid fish, is a seminal example of an endangered aquatic species in the Midwestern USA. Populations and their associated critical habitats may experience potential direct and/or indirect effects from anthropogenic activity. However, potential impacts on fish populations from alterations in the food web are difficult to predict because they are based on complex dynamics of food web... | ||

| ###RSS_DATE### | ||
| Publication date: 1 August 2019Source: Ecological Modelling, Volume 405Author(s): Dmitrii O. LogofetAbstractThe bilberry-vs.-cowberry fine-scale dynamics has been modelled by a discrete Markov chain of transitions among the four observable statuses of permanent sample plots: bilberry (Vaccinium myrtillus) alone, cowberry (V. vitis-idaea) alone, both species, and species-free (Logofet and Maslov, 2019). Six successive examinations of spp. presence/absence on 20 × 20 cm quadrats located along permanent transects in a Scots pine boreal forest were initiated in 1980, 26 years after a... | ||

| ###RSS_DATE### | ||
| Publication date: 24 July 2019Source: Ecological Modelling, Volume 404Author(s): Q. Canelles, N. Aquilué, A. Duane, L. BrotonsAbstractLandscape models are comprehensive tools that allow for an understanding of landscape dynamics and a means of deriving future projections in the context of global change. Vegetation and ecological processes such as growth, death or regeneration are essential components of forest landscape dynamics, but their inclusion in landscape-level modelling frameworks is not straightforward as there is a trade-off between model feasibility, desirable complexity and... | ||

| Publication date: 24 July 2019Source: Ecological Modelling, Volume 404Author(s): P.J. García Nieto, E. García-Gonzalo, J.R. Alonso Fernández, C. Díaz MuñizAbstractAlgal atypical productivity, also called eutrophication, is a process where the phosphorus content in the water, together with aquatic flora, increases, causing high Chlorophyll levels and affecting the water quality and its possible applications. Therefore, it is important to be able to anticipate such circumstance to avoid subsequent hazards. In this paper, a model that estimates the conditions where an abnormal growth of... | ||
| The effective hydrological neighborhood: A new concept to formulate harvest area constraints | ||
| ###RSS_DATE### | ||
| Publication date: 24 July 2019Source: Ecological Modelling, Volume 404Author(s): J.C. Giménez, L. Diaz-Balteiro, M. BertomeuAbstractForest managers have struggled to develop several measures to mitigate the impacts of logging operations on soil erosion. Two measures have consisted in considering slope restrictions and limiting the size of clearcut harvest areas in timber harvest scheduling models by means of adjacency constraints. However, these constraints build on an externally predefined limit on harvest area valid to all stands regardless of their topographic features. Thus, we... | ||
| Sensory perception plays a larger role in foraging efficiency than heavy-tailed movement strategies | ||

| Publication date: 24 July 2019Source: Ecological Modelling, Volume 404Author(s): Diana E. LaScala-Gruenewald, Rohan S. Mehta, Yu Liu, Mark W. DennyAbstractAnimals must balance their rates of energetic intake and expenditure while foraging. Several mathematical models have been put forward as energetically optimal foraging strategies when the food environment is sparse (i.e., the distance between food patches in the environment is much larger than the distance from which the forager can perceive food). In particular, Lévy walks with a power law exponent approaching 1 are considered optimal... | ||
| Effects of land-use data resolution on hydrologic modelling, a case study in the upper reach of the Heihe River, Northwest China | ||

| Publication date: 24 July 2019Source: Ecological Modelling, Volume 404Author(s): Xin Jin, Yanxiang Jin, Donghai Yuan, Xufeng MaoAbstractLand-use/land-cover (LULC) data represent important inputs in hydrologic models. The LULC data can affect modelled watershed hydrologic processes by altering the rates of interception, infiltration, evapotranspiration and groundwater recharge that govern the timing and volume of surface and river runoff. A thorough understanding of the impacts of LULC resolution on hydrologic modelling is thus essential and important. Generally, differences in the... | ||
