Comparing the impact of cloudiness on carbon dioxide exchange in a grassland and a maize cropland in northwestern China
Ecological Research - Tập 27 - Trang 615-623 - 2012
Light quantity and quality strongly influence plant growth. However, different ecosystems have different capabilities to assimilate solar radiation. In this study, the effects of cloudiness intensity on the net ecosystem exchange of carbon dioxide (NEE) were compared between an alpine grassland (with lower leaf area index) at A’Rou and an oasis maize cropland (with higher leaf area index) at Yingk...... hiện toàn bộ
Local adaptations of larvae of the butterfly Pieris napi to physical and physiological traits of two Arabis plants (Cruciferae)
Ecological Research - - 2009
Herbivorous insects are expected to adapt to the defensive traits of local host plants. Using two closely related plants, we showed that herbivorous insects of the same species vary their adaptations according to the different traits of each of their local host plants. The leaves of the cruciferous plant Arabis flagellosa are tougher and more difficult to digest for larvae of the butterfly Pieris ...... hiện toàn bộ
Colony-dependent sex differences in protozoan communities of the lower termite Reticulitermes speratus (Isoptera: Rhinotermitidae)
Ecological Research - Tập 31 - Trang 749-755 - 2016
In many animals, sex differences in hormones, behavior, and immunity lead to differences in their gut microbial communities. One of the best-known examples of mutualistic symbiosis is that between lower termites and their intestinal protozoa. Although differences in the protozoan communities of different castes have been studied in lower termites, nothing is known about the sex differences in prot...... hiện toàn bộ
Land-use selection by dandelions in the Tokyo metropolitan area, Japan
Ecological Research - Tập 6 - Trang 233-246 - 1991
Land use by native and introduced dandelion groups in man-made habitats was studied at 7090 survey points in the Tokyo metropolitan area, Japan, in order to clarify the replacement phenomenon occurring among dandelions. In the center of Tokyo, where the native group was rare, the percentage occurrence of the introduced group was lower than in other regions, whereas in the outskirts of Tokyo, both ...... hiện toàn bộ
Seasonal changes in parotid and rumen papillary development in Mongolian gazelle (Procapra gutturosa Pallas)
Ecological Research - Tập 18 - Trang 65-72 - 2003
The Mongolian gazelle (Procapra gutturosa Pallas) lives in the Mongolian Plateau, where conditions are dry and cold from late autumn to early spring. The climate results in apparent seasonal changes in the nutrition of forage plants on the plateau. The morphology of the gazelle’s rumen papillae and the weight of their salivary glands also reflect these changes. The relative weight of the parotids ...... hiện toàn bộ
Regeneration failure of lakeshore plants under an artificially altered water regime
Ecological Research - Tập 19 - Trang 613-623 - 2004
To reveal the effects of artificial alteration of water level regime on the regeneration of lakeshore plants from seeds, we examined the factors causing regeneration failure in Lake Kasumigaura, Japan. A survey of microtopography within and around a remnant fragment of lakeshore vegetation revealed that, over a large range, the habitat is frequently inundated in spring under the current water regi...... hiện toàn bộ
Abundance, body size, and morphology of bumblebees in an area where an exotic species, Bombus terrestris, has colonized in Japan
Ecological Research - Tập 22 - Trang 331-341 - 2006
An exotic bumblebee species, Bombus terrestris, has colonized in Japan and becomes dominant in some local communities. We examined the effects of land use and bumblebee abundance on the number and body size of bumblebees collected using window traps in a lowland area in the southern Ishikari district, Hokkaido. In 2004, we collected 922 bumblebees of six species using 70 traps at 17 sites. A stati...... hiện toàn bộ
Diurnal variations of chlorophyll fluorescence and CO2 exchange of biological soil crusts in different successional stages in the Gurbantunggut Desert of northwestern China
Ecological Research - Tập 29 - Trang 289-298 - 2014
Biological soil crusts (BSCs) formed by different combinations of photosynthetic algae, cyanobacteria, lichens and mosses are well-developed in the Gurbantunggut Desert of northwestern China. To investigate the different responses of BSCs to environmental factors, the diurnal variations of chlorophyll fluorescence and CO2 exchange of BSCs in different successional stages were measured following ar...... hiện toàn bộ
Effect of sex ratio, habitat factors and neighborhood competition on stem growth in the dioecious tree Fraxinus mandshurica
Ecological Research - Tập 29 - Trang 309-317 - 2014
Growth rates of male and female trees are often different in a dioecious species. In this study, we analyzed sex ratios and the effect of gender, neighborhood competition and habitat factors on the stem growth of dioecious Fraxinus mandshurica trees in a secondary conifer and broad-leaved mixed forest in the Changbai Mountains of northeastern China. The sex ratio in the 5.2-ha study area does not ...... hiện toàn bộ
Response of litter decomposition and related soil enzyme activities to different forms of nitrogen fertilization in a subtropical forestAbstract With the continuing increase in the impact of human activities on ecosystems, ecologists are increasingly becoming interested in understanding the effects of nitrogen deposition on litter decomposition. At present, numerous studies have investigated the effects of single form of nitrogen fertilization on litter decomposition in forest ecosystems. However, f... ... hiện toàn bộ
