A wide array of wildlife species, including many animals, are used in traditional medicines across medicinal systems, Traditional Chinese Medicine (TCM). Due to over-exploitation and habitat loss, the populations animals commonly TCM have declined unable meet market demand. number measures been taken try reduce impact that this large growing for may on wild animal species. Consumer preferences behavior known play an important role consumption protection medicine, thus likely be factor...
Abstract The productivity of ruminants depends largely on rumen microbiota. However, there are few studies the age-related succession microbial communities in grazing lambs. Here, we conducted 16 s rRNA gene sequencing for bacterial identification fluid samples from 27 Tibetan lambs at nine developmental stages (days (D) 0, 2, 7, 14, 28, 42, 56, 70, and 360, n = 3). We observed that Bacteroidetes Proteobacteria populations were significantly changed during growing lambs’ first year life....
The carbon storage in forest ecosystems is closely linked to biomass, and its dynamic changes are of significant importance for assessing structure function, as well their response global climate change. Recently, the research on influencing mechanism has been a hotpot field ecology. However, it remains unclear relationships among stand structure, stability, storage. issues needed be answered follows: How tree density, species diversity, structural characteristics, correlated? Is there...
Sand burial and wind erosion caused by sand movement are common phenomena in desert environments, but the effects on clonal shrub have rarely been investigated. Here, we assessed how movements affect population regeneration capacity of juvenile fragments Calligonum mongolicum growing mobile dunes. We investigated status natural three types dunes (heavy erosion, heavy moderate burial). Clonal propagation C. was markedly different across sites. Moderate sites had largest ramet density bud...
Apiculture has been greatly developed in recent years China. Beekeeping cooperatives and honey manufacturing enterprises have increased rapidly. As a result, variety of products entered the market, adding vitality to food economy; however, adulteration is on rise Previous attempts control mostly relied technical, product-specific measures, there was lack modeling research guide supervision product industry. In order help local governments better from management perspective, this paper...
Abstract In some insect nursery pollination mutualisms, plant hosts impose net costs to uncooperative “cheater” symbionts. These “sanctions” promote mutualism stability but their precise adaptive nature remains unclear. fig–wasp mutualisms host trees ( Ficus spp.) are only pollinated by female agaonid wasps whose larvae use galled fig flowers as food. actively systems, if fail pollinate, sanctions can result via abortion, killing all wasp offspring, or increased offspring mortality within...
Abstract Fig‐pollinating wasps (Agaonidae) only reproduce within fig tree inflorescences (figs). Agaonid offspring sex ratios are usually female‐biased and often concur with local mate competition theory (LMC). LMC predicts less female‐bias when several foundresses in a due to reduced relatedness among intra‐sexually competing male offspring. Clutch size, the produced by each foundress, is strong predictor of agaonid correlates negatively foundress number. However, clutch size variation can...
Abstract The fig tree-fig pollinator mutualism is one of the most tightly knit symbiotic systems. research on ecology non-pollinators which exploit without providing services to host very limited and conclusions about role they play in maintenance this are full contradictions. non-pollinating wasps species highly diverse their feeding habit ecological function, may result different consequences mutualism. Sycophaga testacea an early-ovipositing galler hosted by Ficus racemosa , a potencial...

Fig trees (Ficus spp.) are only pollinated by fig wasps, whose larvae use flowers as food. The ensure pollination increasing the offspring mortality rates of wasps that fail to pollinate. This is achieved selective investment inflorescences, figs yield most benefits (a process common angiosperms). Unlike previous work on sanctions in fig–wasp mutualisms, we used a gynodioecious host species, F. hispida, show sanctioning mechanisms differ between male and female trees, consistent with...

Their structures characterized by means spectroscopic methods, especially H‐, 13 C‐, 2D‐NMR HR‐MS, as well chemical methods...
Habitats of large herbivores have shrunk owing to the expansion human activities. Consequently, wild frequently venture into adjacent farmlands forage for crops. As a result, farmers use fences prevent these from foraging. A dynamic game exists between whether choose set up and farmlands. This study established an evolutionary model herbivorous species. The effects different factors on process were studied using simulations provide theoretical guidance conservation management herbivore Model...
Abstract Although understanding mutualism stability has advanced over the last few decades, two fundamental problems still remain in explaining how mutualisms maintain stable. (i) How does resolve conflict between mutualists resources? (ii) In presence of less cooperative and/or uncooperative symbionts, prevent symbiont populations from becoming dominated by individuals? Many past explanations have assumed that interactions are symmetrical. However, most mutualisms, hosts and symbionts show...
This study investigated the effects of different metabolizable protein (MP) levels on growth performance, nitrogen metabolism, rumen fermentation parameters and ruminal microbial community Hu sheep. Fifty-four female sheep 60 days old, with an average body weight 18.7 ± 2.37 kg, were assigned randomly to three dietary MP groups: (1) low (LMP, 7.38 % MP), (2) middle (MMP, 8.66 (3) high (HMP, 9.93 each group having 6 replicate pens. The feeding trial lasted for 10 adaptation. results showed...
