Summary: In this study, the reliability of cost value inference in connectivity models was assessed under different migration rates, population spatial patterns, and degrees of population size heterogeneity. The study also examined whether considering intra-population variables improved the inference when drift was spatially heterogeneous. The results showed that considering intra-population variables can improve the reliability of cost value inference and better identify the true cost scenarios in certain situations.

Summary: The study identified that landscape structure has a significant impact on the genetic structure of plant populations. Different crop types and the orientation of linear landscape elements play important roles in gene flow among plant populations.

Summary: The study highlights the importance of considering temporal connectivity in assessing the impact of urban expansion on landscape connectivity. Overlooking temporal connectivity can lead to overestimation of the impact of urban expansion, with the degree of overestimation depending on the amount of net habitat loss. Additionally, the study suggests that landscape connectivity may have a delayed response to urban expansion.

Summary: This study examined the influence of habitat quantity and spatial configuration on genetic structure, showing that measuring the amount of reachable habitat (ARH) can effectively describe habitat patterns and predict genetic structure. ARH metrics were found to be relevant predictors of genetic structure components, demonstrating significant impact on allelic richness and genetic differentiation.

Summary: Global aquatic habitats are rapidly degrading and fragmenting, making it important to understand the genetic variability and adaptive potential of aquatic plant species for conservation purposes. This study investigated the genetic diversity and structure of Zizania latifolia populations in China, finding low genetic diversity and high genetic differentiation. Wetland fragmentation had a negative impact on populations. Environmental factors, such as maximum temperature of the warmest month and precipitation seasonality, influenced genetic diversity. Local adaptation was also observed, with certain loci associated with environmental variables.

Summary: This article discusses the potential benefits of integrating landscape graphs and genetic graphs in landscape genetics. By comparing different features and partitions of these graphs, the influence of intra-patch features and inter-patch connectivity on genetic structure can be examined, as well as the sensitivity of genetic diversity and differentiation to landscape factors. Additionally, the integration of these graphs through gravity models can enhance their joint use for various theoretical and applied objectives.

Summary: This study analyzed the impacts of landscape heterogeneity and climate conditions on pollinating insect communities in two economically important mass-flowering crops in Europe. The results showed that flower-visiting insects responded differently to landscape diversity and climate parameters, and these responses varied depending on the crop type. Therefore, it is important to understand the population changes of pollinating insects in response to land use and climate change, in order to ensure the continued provision of pollination services to pollinator-dependent crops in the context of global change.

Summary: Physiographic changes, such as river catchment drainage reorganisations, played an important role in Quaternary species diversification in Sundaland, Southeast Asia, according to simulations using combined landscape evolution and connectivity models. The changes have fragmented the environment into multiple habitats connected by migratory corridors. These results support the theory that rapidly evolving physiography could foster Quaternary biodiversification across Southeast Asia.

Summary: In this article, the role of gender in collaboration patterns is investigated by analyzing gender-based homophily – the tendency for researchers to co-author with individuals of the same gender. The researchers develop and apply novel methodology to analyze the JSTOR articles at various levels of granularity. They found statistically significant behavioral homophily across the JSTOR corpus, even when gender indicators were missing in the data.

Summary: This study investigated the genetic divergence of the leaf-cutting ant Atta cephalotes in the western range of the northern Andes in Colombia. The results showed that both geographic distance isolation, climatic conditions, and physical barriers of the Andes mountains played a role in the genetic divergence, with environmental factors being more important than physical barriers. This study enhances our understanding of the forces shaping population divergence in complex habitat landscapes.

Summary: The importance of optimization in graph-theoretic algorithms and landscape connectivity methods is explored in this article. It is pointed out that indeterminate solutions may introduce bias in the results, and two optimization targets are distinguished. The use of complete planar graphs is advocated over thresholding in landscape graph creation.

Summary: Uncertainties in tree mortality controls make it difficult to predict forest responses to land-use and climate change. By tracking tree biomass in tropical forests across Puerto Rico and the U.S. Virgin Islands, we identified the top predictors of small tree survival. These predictors include tree crown ratio and height, species traits, and factors reflecting local disturbance and the system state.

Summary: This study examined the impacts of human activity on the spatial distribution of plant diversity on inhabited islands in the Shengsi Archipelago, China. Factors such as island morphology, landscape, proximity, ecology, terrain, and soil, as well as different levels of human influence, were quantified. The results showed that area and isolation were the most critical factors affecting the richness and diversity of shrubs and herbs in the sub-archipelago and island scales.

Summary: This study evaluated the forest landscape restoration (FLR) status in the Yi River watershed based on remote sensing images during 2015-2020, exploring the importance of landscape connectivity for local flora and fauna. The results showed different distance threshold values for analyzing forest landscape connectivity (FLC) in hills and low mountains. The impact of reforested patches on improving FLC varied between hills and low mountains.
