Anywhere but here: local conditions motivate dispersal in Daphnia by Philip Erm, Matthew D. Hall, Ben L. Phillips

“…We also observed a small apparent increase in dispersal in replicates with higher population densities, but this effect was smaller than the effect of resource constraint, and not found to be significant. …”

How to Systematically Evaluate the Greenspace Exposure of Residential Communities? A 3-D Novel Perspective Using UAV Photogrammetry by Tianyu Xia, Bing Zhao, Zheng Xian, Jinguang Zhang

“…These metrics were calculated using the classified point clouds from four typical Chinese residential communities with different residential greenery types and population densities. The results showed that our method could quantitatively identify the differences in residential GS exposure within urban residential communities. …”

Microgeographic Wing-Shape Variation in <i>Aedes albopictus</i> and <i>Aedes scapularis</i> (Diptera: Culicidae) Populations by Rafael Oliveira-Christe, André Barretto Bruno Wilke, Mauro Toledo Marrelli

“…Both species are highly anthropophilic and are often abundant in places with high human population densities. Because of the great epidemiological importance of these two mosquitoes and the paucity of knowledge on how they have adapted to different urban built environments, we investigated the microgeographic population structure of these vector species in the city of São Paulo, Brazil, using wing geometric morphometrics. …”

Ecosystem Services Provisioning, Urban Growth and the Rural–Urban Interface: A Case Study from China by Haiying Feng, Victor R. Squires, Jingji Wu

“…Especially in urban areas with high population densities (as in most of China) and high demand for EG & S, the future availability of such services must be considered in order to promote effective and sustainable decision making and prevent further ecosystem degradation. …”

TcI/TcII co-infection can enhance Trypanosoma cruzi growth in Rhodnius prolixus by Catarina A C Araújo, Peter J Waniek, Ana M Jansen

“…The distribution patterns and parasite population densities were evaluated at 7, 14 and 21 days after feeding (daf) by quantification of parasites using Neubauer haemocytometric measurements and mini-exon PCR to identify TcI and TcII subpopulations. …”

Species Composition and Distribution of Jellyfish in a Seasonally Hypoxic Estuary, Hood Canal, Washington by BethElLee Herrmann, Julie E. Keister

“…Moderate hypoxia seemed to have no detrimental effect on jellyfish in Hood Canal, and may have resulted in high population densities, which could influence essential fisheries and trophic energy flow.…”

Estimated Mortality of Selected Migratory Bird Species from Mowing and Other Mechanical Operations in Canadian Agriculture by Joerg Tews, Daniel G. Bert, Pierre Mineau

“…In our step-by-step modeling approach we (i) quantified the amount of various types of agricultural land in each Bird Conservation Region (BCR) in Canada, (ii) estimated population densities by region and agricultural habitat type for each selected species, (iii) estimated the average timing of mechanical agricultural activities, egg laying, and fledging, (iv) and used these values and additional demographical parameters to derive estimates of total mortality by species within each BCR. …”

Commonness and rarity pattern of plant species within <i>Terai</i> grassland of northeastern Uttar Pradesh, India by Sumit Srivastava, Ashish Dvivedi, R.P. Shukla

“…Rare species showed restricted as well as localized distributions and were typically sampled at low population densities. The rare occurrences of once frequent and widespread species probably reflect acute fragmentation and shrinkage of specialized habitats as a result of intense cultural activities. …”

Spatio-temporal Analysis of Urban Growth and Its Effects on Wetlands in Rwanda: The Case of Rwampara Wetland in the City of Kigali by G. Rwanyiziri, C. Kayitesi, M. Mugabowindekwe, R.V. Byizigiro, E. Muyombano, M.B. Kagabika, T. Bimenyimana

“…The results also revealed that demographic factors (i.e. a high population growth rate and high population  densities) were mainly responsible for urban growth and degradation of wetland resources in the area under investigation. …”

Prolonged phloem feeding by the spotted lanternfly, an invasive planthopper, alters resource allocation and inhibits gas exchange in grapevines by Andrew D. Harner, Heather L. Leach, Lauren Briggs, Michela Centinari

“…We conclude that intensive late‐season phloem feeding by large adult SLF population densities (≥8 SLF shoot−1) can induce carbon limitation, with the potential for negative year‐after effects in cases of severe belowground carbon depletion. …”
