Abstract:

To mitigate possible negative impacts of cascade dams in the Lower Jinsha River and maintain the natural flow regime of national natural reserve areas of rare and special fishes of the upper Yangtze River, environmental flow (e-flow) demands need to be considered in the cascade dams operation. Due to lack of regular ecological observation data, multiple hydrology-based e-flow methods including Tennant, minimum monthly flow, 7Q10 and Q90 are applied to provide specific e-flow prescripts to guide the reservoir release. A joint operation optimization model is developed for the cascade dams in the

Abstract:

The implementation of environmental flows is of the utmost importance for ecosystem protection and restoration in dammed rivers. A key challenge in optimizing dam regulation is the uncertainty of the ecohydrology relationship between flow release and ecological response. In the present paper, we develop a framework of dam classification to organize the categories of the ecohydrology relationship for implementing environmental flows. Dams are classified from three major categories that differ in dam properties, hydrological alteration, and downstream hydrobiological diversities based on the rel

Abstract:

From the economic perspective, China has made remarkable progress, yet environmental concerns represent an alarm to the country’s long-term prosperity. The associated relationship between green investment and the green economy has important implications for the environment. Whether there is an interactive relationship between green investment and green ecology, current views seem to be at odds with each other. This paper employs a panel vector autoregressive model to construct an empirical analysis of China’s provincial panel data from 2005 to 2019. Specifically, generalized moment estimation,

Abstract:

The movement rates of sharks are intrinsically linked to foraging ecology, predator–prey dynamics and wider ecosystem functioning in marine systems. During ram ventilation, however, shark movement rates are linked not only to ecological parameters, but also to physiology, as minimum speeds are required to provide sufficient water flow across the gills to maintain metabolism. We develop a geometric model predicting a positive scaling relationship between swim speeds in relation to body size and ultimately shark metabolism, taking into account estimates for the scaling of gill dimensions.

Stable isotope values of primary consumers have been proposed as indicators of human impacts on nitrogen dynamics. Until now, these values have been related only to single-stressor gradients of land-use intensity in stream ecology, whereas potential interactive effects of multiple stressors are unknown. It also remains unknown whether stable isotope values of different primary consumers show similar relationships along gradients of stressor intensities.

Abstract:

In this article, I examine artworks from two periods in the history of media art—the 1970s and the 2010s—to demonstrate how changes in our haptic relationship to screen media shift the site of criticality in contemporary media art from disruption of electronic feedback toward an intensification and embrace of image flows that actively seek the viewer's touch and gesture. I situate video art within the shifting concept of flow in everyday media consumption, reading video art practices within a larger matrix of bodily and cultural engagement with screens. I locate touch and gesture as both theme

Abstract:

Prediction and assessment of the effects of habitat change on aquatic biodiversity remain a hot issue globally. This paper developed a practical methodology based on ecosystem models to comprehensively assess the effects of habitat changes on aquatic biodiversity. The partial least-squares (PLS) method was used to analyse the key hydrological and water quality factors influencing riverine aquatic organisms. The biomass of aquatic organisms under undisturbed conditions was simulated using the food web model Ecosim. Based on the relationship between habitat factors variation and biodiversity var

Abstract:

The role of ecology in diversification has been widely investigated, though few groups have been studied in enough detail to allow comparisons of different ecological traits that potentially contribute to reproductive isolation. We investigated larval performance within a species complex ofLycaeidesbutterflies. Caterpillars from seven populations were reared on five host plants, asking if host-specific, adaptive larval traits exist. We found large differences in performance across plants and fewer differences among populations. The patterns of performance are complex and suggest both conserved

In the new era, coordinating the relationship between population flow and forestry ecological security has become an important challenge. In this study, we take Heilongjiang Province in China as an example, and through the combination of macro data and micro in-depth interviews, we explore whether population mobility really affects the intrinsic mechanism of forestry ecological security from the perspective of population exodus from forest areas. Based on the DPSIR model, we constructed a forestry ecological security evaluation index system, used the TOPSIS multi-objective decision analysis me

Abstract. While we now know that marine N2 fixation is a significant source of new nitrogen (N) in the marine environment, little is known about the fate of this production, despite the importance of diazotrophs to global carbon and nutrient cycles. Specifically, does new production from N2 fixation fuel autotrophic or heterotrophic growth, facilitate carbon (C) export from the euphotic zone, or contribute primarily to microbial productivity and respiration in the euphotic zone? For Trichodesmium, the diazotroph we know the most about, the transfer of recently fixed N2 (and C) appears to be pr

AbstractTamarisk, a shrub or small tree native to Eurasia, was introduced to North America in the early 1800s and is now naturalized throughout many riparian areas of the southwestern United States, where extensive research has been conducted. It is a more recent invader to the northern Great Plains, and fewer studies have been conducted on tamarisk ecology and management in this area. The objectives of this research were to investigate the overwintering potential of tamarisk seeds in Montana and the relationship between hydrologic conditions and historic tamarisk establishment.

Abstract:

Dispersal is one of the most fundamental components of ecology, and affects processes as diverse as population growth, metapopulation dynamics, gene flow and adaptation. Although the act of moving from one habitat to another entails major costs to the disperser, empirical and theoretical studies suggest that these costs can be reduced by having morphological, physiological or behavioural specializations for dispersal. A few recent studies on different systems showed that individuals exhibit personality-dependent dispersal, meaning that dispersal tendency is associated with boldness, sociabilit

Schizophonic soundscapes in Murray Schafer's critical acoustic ecology mean a split between listening and seeing, between space and place, between audience and communicator. His idea of a gap between senses is based on electronic media like radio and telephone, but it gains new actuality in modern (multimedia) times. The new technology and its users have too experimented with the creative inversion of schizophony in sound and vision.

Abstract:

Recent debates have challenged the very foundation of political ecology. One important critique, stemming from the work of Vayda and his associates, promotes a problem-specific, ecological, and positivistic approach to the analysis of the causes of environmental change. Their focus on the “event,” however, is seemingly at odds with earlier concerns with process. Utilizing a case study of the Bedouin people in Saudi Arabia, I argue that the key ecological events upon which this research focuses, the Kuwaiti oil fires and the ongoing process of desertification, provide poor isolates of the human

Abstract:

(Uploaded by Plazi for the Bat Literature Project) Body size is a key morphological attribute, often used to delimit species boundaries among closely related taxa. But body size can evolve in parallel, reaching similar final states despite independent evolutionary and geographic origins, leading to faulty assumptions of evolutionary history. Here, we document parallel evolution in body size in the widely distributed leaf-nosed bat genus Hipposideros, which has misled both taxonomic and evolutionary inference. We sequenced reduced representation genomic loci and measured external morphological
