Negative effects of artificial nest boxes on birds: A review

Avian Research, Journal Year: 2023, Volume and Issue: 14, P. 100101 - 100101

Published: Jan. 1, 2023

Artificial nest boxes are placed to attract birds and breed in a specific location, they widely used avian ecology research the attraction of insectivorous birds. There is evidence that artificial can adversely affect breeding fitness but no great focus has been on this issue by researchers. Therefore, we retrieved 321 papers regarding published from 2003 2022 'Biblioshiny' program extract integrate keywords; then summarized adverse effects success. The studies highlighted many drawbacks misuses designing placement boxes; furthermore, bird was decreased their inappropriate selection, thus reducing Regarding box production, there were shortcomings construction material, color, smell, structural design used. Nest also at densities, locations, orientations, heights, managed incorrectly. Finally, propose suggestions for more efficient safer future use conservation.

Influence of nature reserve road traffic disturbance on soil carbon

Global Ecology and Conservation, Journal Year: 2024, Volume and Issue: 54, P. e03103 - e03103

Published: July 24, 2024

Road traffic has long been recognized as a considerable source of ecological disturbance, compromising the integrity natural ecosystems from their pristine baseline state. Pollutant deposition vehicular emissions significantly contributes to environmental contamination, while associated human activities exacerbate ecosystem disruptions. In designated conservation zones, including nature reserves, land-use practices such pastoralism and agriculture are subject regulation. Nevertheless, influence road on structure processes, particularly concerning carbon (C) sequestration its spatial heterogeneity, warrants further research. This consideration is critically relevant in understanding intricate C fractions dynamic interplay with factors. this study, we meticulously selected four distinct locations along principal roadway within national reserve. For each site, experimental measuring 2 m * were established at intervals m, 10 20 30 40 50 road's edge. Observational data accrued during peak vegetative growth seasons August both 2020 2021. Within plot, soil cut-ring samples procured for comprehensive analysis (Total Carbon, TC, g/kg; Carbon Density, g/m2; Readily Oxidizable ROC, Dissolved Organic DOC, mg/kg; Microbial Biomass MBC, Cumulative Mineralization CMC, mg(CO2-C)*(kg*soil)−1; Soil Inorganic SIC, g/kg), chemical properties (pH; Electrical Conductivity, EC, us/cm; Matter, SOM), physical (Soil Water, SW, %; Bulk BD, g/cm3; area conditions).

The impact of the Qinghai-Tibet highway on plant community and diversity

Frontiers in Plant Science, Journal Year: 2024, Volume and Issue: 15

Published: June 28, 2024

Roads are an increasingly prevalent form of human activity that drives the decrease in plant community functions and threatens global biodiversity. However, few studies have focused on changes function diversity alpine meadows caused by road infrastructure Tibetan Plateau. In this study, species diversity, functional stability were examined at different distances from Qinghai-Tibet highway. The results showed intensified degradation vegetation, which significantly altered structure. This effect gradually decreased near to far Plant cover highest intermediate (50–100 m) roadway; lowest grassland most disturbed (0 m), tended stabilize farther away (250 m). Our findings indicate synchronized with largely determines outcome degraded stability. provide a reference point for restoring areas mitigating ecological impacts roads.

NDVI Characteristics and Influencing Factors of Typical Ecosystems in the Semi-Arid Region of Northern China: A Case Study of the Hulunbuir Grassland

Land, Journal Year: 2023, Volume and Issue: 12(3), P. 713 - 713

Published: March 20, 2023

The semi-arid region of northern China is highly sensitive to environmental changes, especially the Hulunbuir Grassland, which has an essential ecological status and a fragile environment. This study focused on NDVI characteristics three different ecosystems their dominant influencing factors. It proposed method show immediate effects factors statistical level. results showed that: (1) floodplain wetland > meadow sand ribbon. There were obvious differences among ecosystems, spatial distribution was consistent with altitude. (2) main explanatory phenological period, humidity, temperature, accumulated precipitation, runoff, evaporation, accounted for 68.8% total explanation. (3) Phenological precipitation positively correlated NDVI. Temperature evaporation had positive effect within certain range. revealed in enriched theory factors, provided scientific basis future research regional conservation.

A comprehensive understanding of the effects mountain roads on plant diversity is critical to finding most effective solutions for managing this particular driver. Little known, however, about simultaneous that road have multiple facets biodiversity, although are considered be one major disturbances in Qionglai range. In study, we analyzed impact (taxonomic, functional and phylogenetic diversity) study area using Hill numbers by comparing between roadside interior plots at landscape scale, then, used linear mixed models analyze effect along an elevational gradient. The results showed lacked 29.45% total number species with traits (such as a relatively high specific leaf (SLA), low dry matter content (LDMC) old clades) exclusively contained 14.62% species. Compared community, taxonomic, community decreased no more than 26.78%, 24.90% 16.62%, respectively. Taxonomic dominant common greater changes disturbances, while rare greatest change diversity. homogenization communities was accompanied homogenization. Additionally, these three characteristics peak clipping elevation Our findings highlight negative range, promote similar functional, composition, extent contributed compositional evenness.

The Hailar River is an important river in the Inner Mongolia Autonomous Region, China. It plays extremely role maintaining ecological balance of region. However, recent decades, and its surrounding areas have been developed at a high rate wetland resources faced various threats. In this study, vegetation changes wetlands were analyzed using remote sensing data from Landsat TM (1987, 2001, 2010) OLI-TIRS (2019) satellites. A change model was Matlab software to assess area. There significant lower study site between 1987 2019. increase open sand habitat with sparse area 1.08 km2, decrease grassland 13.17 forest 15.91 km2. spatial distribution normalized difference index (NDVI) varied across overall. types distance river. are two possible explanations for positive negative trends. where water supply sufficient relatively stable, cover gradually increasing herbaceous plant community evolving into scrub woodland community. lacking, there sense vegetation. Therefore, suggests that existing should be protected, used wisely, rationally provide sustainable next generation.
