Genetic connectivity is a key factor for maintaining the persistence of populations in fragmented landscapes. In highly modified landscapes such us peri-urban areas, organisms' dispersal among fragmented habitat patches can be reduced due to the surrounding matrix, leading to subsequent decreased gene flow and increased potential extinction risk in isolated sub-populations. However, few studies...

Functional connectivity is essential for the long-term persistence of populations. However, many studies assess connectivity with a focus on structural connectivity only. Cityscapes, namely urban landscapes, are particularly dynamic and include numerous potential anthropogenic barriers to animal movements, such as roads, traffic or buildings. To assess and compare structural connectivity of hab...

The prairie population of the loggerhead shrike (Lanius ludovicianus excubitorides) is dependent upon two characteristics of a grassland landscape that require specific management to maintain: shrubs taller than 1.8 m tall for nesting and tall grass for foraging. The purpose of this study is to measure the landscape variables that are important to loggerhead shrike persistence at landscape spat...

using quarterly data from 2002:1 to 2013:2 we study the persistence in the inflation rates in iran based on the total cpi and the cpi in 12 subgroups. the persistence is investigated using two different tools: (i) the adf unit root test and (ii) bootstrap confidence intervals. we calculate a 90% confidence interval for the sum of the autoregressive coefficients, as a measure of persistence, usi...

Ability to predict species distribution in a landscape is of crucial importance for natural resource management and species conservation. Therefore, the understanding of species habitat requirements and spatio-temporal dynamics in occurrence is needed. We examined patch occupancy patterns of the Siberian flying squirrel Pteromys volans in northern Finland across a seven year study period. Fores...

buffering provided by this continuum is the capacity of the refugium [8]. Global climate projections are now unidirectional (e.g., Figure 2 in [5]). The separation of stepping-stone, holdout and microrefugia components (sensu [5]) of the refugium continuum is therefore rendered impotent for conservation planning under anthropogenic climate change. All three proposed components are refugia, as t...

Despite the close affinity between collective memory and urban structures as the relationship between what is hidden and what is visible; rapid changes throughout the city have caused a disconnection between integrated memories and landscape cohesion. As a context for memories, the historical urban landscape proves to be valuable. The present research seeks to identify elements and signs in urb...

This paper has three primary aims: to establish an effective means for modelling mainland-island metapopulations inhabiting a dynamic landscape; to investigate the effect of immigration and dynamic changes in habitat on metapopulation patch occupancy dynamics; and to illustrate the implications of our results for decision-making and population management. We first extend the mainland-island met...

Abstract We develop a method for calculating the persistence landscapes of affine fractals using parameters corresponding transformations. Given an iterated function system transformations that satisfies certain compatibility condition, we prove there exists transformation acting on space landscapes, which intertwines action system. This latter is strict contraction and its unique fixed point l...
