Abstract Aims The objective of this study was to learn the effect of sheep digestive tract on the recovery and germination of seeds of fifteen leguminous plants in the northern Xinjiang region.Methods The seeds were collected from fifteen leguminous species which were widely distributed in the natural mowing pasture of the northern Xinjiang region. After determining their morphological characteristics (seed length, width, thickness, single seed mass, and seed shape index), seeds were fed to sheep. Faeces collection was carried out at 6, 12, 24, 36, 48 and 72 h after seeds were eaten by sheep. Seed recovery percentage (SRP), mean retention time (MRT) and seed germinability before and after ingested were determined, and the relationships between seed size, seed shape index and SRP, MRT after ingested were also studied.Important findings Seed mass ranged from 1.50 to 37.68 mg, and seed shape index between 0.001 and 0.12, which indicated the seeds are all medium or large type sphericity (round) seeds. Seed excretion dynamic followed a Gaussian model: Y = 0.02 + 0.74e -0.5((X- 29.61)/9.41)2 (R2 = 0.62, p < 0.01), and excretion peak appeared 24-36 h after digestion. Seed recovery rate was ranged from 39.25% (Glycyrrhiza glabra) to 4.28% (Melilotus officinalis). The MRT ranged from 37.19 h (Melilotus officinalis) to 22.33 h (Oxytropis sinkiangensis). The relationship between SRP and seed size is expressed as the equation Y = 6.45 + 2.05X - 0.04X2 (R2 = 0.41, p < 0.05). The relationship between seed SRP and seed shape index is expressed as the equation Y = 2.59 + 36.97e -24.47X (R2 = 0.37, p < 0.05). The relationship between MRT and seed size is expressed as the equation Y = 12.48 + 37.44e -0.07X (R2 = 0.37, p < 0.05). The relationship between MRT and seed shape index is expressed as the equation Y = 3.93 + 2055.33X - 21757.99X2 (R2 = 0.42, p < 0.05). The results suggested that leguminous seeds in larger, or smaller, or irregular shape were more easily digested and excreted by sheep. After digested by sheep gut, germination percentages of recovered seeds of Caragana pleiophylla (35.17%) was significantly decreased (p < 0.05) compared with that of seeds before ingested (96.22%). Similarly, seed germination percentages of Trifolium lupinaster and Astragalus alopecurus seeds were decreased than those of no ingested seeds (not significantly, p > 0.05), but the germination percentages of other twelve kinds seeds were significantly increased (p < 0.05).

BlackshawRE, RodeLM ( 1991). Effect of ensiling and rumen digestion by cattle on weed seed viability Weed Science, 39, 104-108. DOI:10.1007/BF00224983URL [本文引用: 1] Studies were conducted to determine the effect of ensiling and/or rumen digestion by cattle on the germination and viability of several common weed species. Seed survival of grass species subjected to ensiling and/or rumen digestion tended to be less than that of broadleaf species. Downy brome, foxtail barley, and barnyardgrass were nonviable after either ensiling for 8 weeks or rumen digestion for 24 h. Some green foxtail (17%) and wild oats (0 to 88%) seeds survived digestion in the rumen but were killed by the ensiling process. Varying percentages of seeds of kochia, redroot pigweed, common lambsquarters, wild buckwheat, round-leaved mallow, and field pennycress remained viable after ensiling (3 to 30%), rumen digestion (15 to 98%), and ensiling plus rumen digestion (2 to 19%). A time course study of rumen digestion indicated that loss of seed viability often was not a gradual process. With some species, there was an initial lag phase while degradation of the protective seed coat likely occurred, followed by a rapid decline in embryo viability. The diet fed to livestock appeared to affect viability losses caused by rumen digestion. Estimates of seed survival with varying rates of passage through the rumen due to differing ratios of grain to forage in the diet are presented.

Endozoochory of Mediterranean aquatic plant seeds by teal after a period of desiccation: Determinants of seed survival and influence of retention time on germinability and viability Aquatic Botany, 93, 99-106. DOI:10.1016/j.aquabot.2010.04.001URL [本文引用: 1] The capacity of eight wetland seeds to be internally dispersed by common teal ( Anas crecca L.) after a dry period typical of natural Mediterranean wetlands was experimentally quantified. These plant taxa ( Chara spp., Echinochloa crus-galli (L.) P. Beauv., Eleocharis palustris (L.) Roem. & Schult, Polygonum lapathifolium L., Potamogeton nodosus Poir., Potamogeton pusillus L., Schoenoplectus mucronatus (L.) Palla, Scirpus maritimus L.) were frequently ingested by teal in the field. Captive teal were fed with known quantities of dry seeds and faecal samples were collected at intervals of 1–2 h for 48 h. The proportion of seeds retrieved after gut passage that germinated varied between taxa from 3% to 83%. From 2% to 63% of the seeds ingested were recovered intact, and 18-95% of these were still viable. Therefore, an overall 32% of the seeds ingested were evacuated in a viable condition, ranging from 0.2% for Chara spp. to 54% for S. mucronatus. Mean seed retention time was 3–5 h. Overall, 94% of seeds were evacuated within 12 h, but 2% were recovered after more than 24 h. Seed viability was reduced at longer retention times, although viable seeds of all taxa except Chara spp. were recovered 44–48 h after the experiment began. Germinability was increased by gut passage, although for some species this effect was only significant after stratification, indicating that they exhibit both mechanical and physical dormancy. Seed germination was accelerated by gut passage, especially at longer retention times. Gut passage increased the proportion of viable seeds, suggesting selective digestion of non-viable ones. Endozoochorous transport by teal appears to be a widespread dispersal mechanism among wetland plants.

DOI:10.1890/08-1629.1URLPMID:20120817 [本文引用: 1] Disperser effectiveness is the number of new plants resulting from the activity of one disperser relative to other dispersers or to nondispersed seeds. Effectiveness remains largely uninvestigated due to the complexity of its measurement. We measured the effectiveness of seed dispersers (Larus michahellis, Turdus merula, and Oryctolagus cuniculus) of the shrub Corema album (Empetraceae) using a simulation model of the recruitment process that was parameterized with field data of seed dispersal, predation, and seedling emergence and validated with independent data on seedling density. The model allows tracking the fate of seeds dispersed by each animal and estimating, for the first time, disperser effectiveness as seedlings per square meter contributed by each disperser. It also allows quantifying the relative importance of different recruitment processes in determining the quantity and spatial distribution of recruitment. Larus michahellis was the most effective disperser in two of the three habitats studied, contributing 3-125 times more than the other two species, whose lower effectiveness depended mostly on deposition patterns (T. merula) or deleterious effects on seedling emergence (O. cuniculus). The dependence of the plant on each disperser differed between habitats and was the greatest in sparse scrub, where recruitment depended almost exclusively on gulls (90%). Quantity and quality of dispersal were not correlated; quality was a better predictor of disperser effectiveness. Seedling emergence was the most crucial process in determining both the spatial pattern of recruitment among microhabitats (99.8% of variance explained) and the quantity of recruitment within microhabitats (43-83%). A sensitivity analysis showed that increasing seed dispersal improved the recruitment for all dispersers when there was no competition for fruits. However, with limited fruits, increased dispersal of lower quality dispersers reduced overall recruitment. Our results show important differences in effectiveness among dispersers and illustrate the different influences of the components of effectiveness, which varied depending not only on the disperser but also on the circumstances (e.g., type of habitat).

DOI:10.1111/j.0022-0477.2005.00982.xURL [本文引用: 1] Summary 1 Dispersal of endozoochorous seed involves uptake by a herbivore and exposure to different kinds of digestive fluids during passage through the gastrointestinal tract. Assessment of the ecological significance of endozoochory therefore requires examination of the survival rate of seeds during this phase. 2 A feeding experiment was conducted with seeds of 19 plant species that are important constituents of temperate semi-natural grasslands and five animal species (two ruminants, two colon fermenters and a caecum fermenter). Mean retention time of germinable seeds was determined and seed characteristics that might affect germination success were examined. 3 Gut-passed seeds had a much lower germination success (0–26%) than non-gut-passed seeds either sown directly on dung (2–79%) or bare soil (7–89%). 4 Relative germination success differed considerably between both plant and animal species. This may result from complex, herbivore-specific interactions between animal behaviour (chewing, digestion) and seed characteristics. 5 Germination success was positively related to seed longevity and, remarkably, also to seed mass and seed shape. Retention time of germinable seeds varied from c . 12 hours (rabbit) to 72 hours (ungulates), potentially allowing long-distance seed dispersal. This study highlights both the complex interaction between animal species and seed characteristics and the considerable differences in germination success of gut-passed seeds, which exist between plant species. The loss of seed germinability after gut passage calls into question the ecological significance of endozoochory, although the costs of other dispersal mechanisms remain to be tested.
CouvreurM, CosynsE, HermyM, HoffmannM ( 2005). Complementarity of epi- and endozoochory of plant seeds by free ranging donkeys Ecography, 28, 37-48. DOI:10.1111/j.0906-7590.2005.04159.xURL [本文引用: 1] Epizoochory and endozoochory are well-recognized long-distance seed dispersal mechanisms, yet their relative importance has hardly been studied before. Here, epi- and endozoochory were compared on donkeys foraging in a species-rich 100 ha coastal dune ecosystem, through in vitro germination of zoochorous material obtained by fur brushing and dung collection. We identified 6675 seedlings of 66 plant species, covering 20% of the species recorded in the study area. Of the 66 species, only 16 occurred in both epi- and endozoochory samples, demonstrating the complementarity of both dispersal mechanisms. The species composition in the zoochory samples reflected a strong seasonality, and seedling numbers were partly correlated with species abundance in the study area. The non-zoochorously dispersed species in the study area differed from the zoochorous species in seed size and weight, plant height, life span, dispersal strategy and seedbank persistence. Dispersal-relevant plant traits were used to derive dispersal-functional plant types for all species in the study area. Epizoochory showed to be more specific than endozoochory and was associated with a more narrow range of dispersal-functional plant types.

DOI:10.1111/j.1438-8677.2010.00335.xURLPMID:21134095 [本文引用: 2] Abstract Grazing mammals are regarded as major vectors in seed dispersal of grassland plants, through seed ingestion and subsequent excretion (endozoochory). The (evolutionary) ecology underlying this dispersal mode is relatively poorly understood because there are limited data, among others, on how seed attributes perform in this process (and could thus be selected for). For seed mortality following ingestion, contrasting patterns described for the role of simple seed traits seem partly due to inadequate comparative analytical methods. We conducted a feeding experiment in which controlled seed quantities from 48 grassland herb and grass species were fed to cattle. Seed mass, length and shape measurements were related to seed mortality rate using phylogenetically independent contrasts, which account for taxonomic interdependence. The proportion of seeds surviving the digestive tract was generally low, but it reached 100%, with increased germination for some species. Neither seed size nor shape correlated significantly with mortality. Structural traits are likely to overrule these simple seed traits, as illustrated by high survival of species having water-impermeable seeds. As this trait has interesting properties with respect to intraspecific variation and genetics, it could provide opportunities for inference on evolutionary consequences for this type of dispersal.

DOI:10.3844/ojbsci.2006.23.27URL [本文引用: 1] ABSTRACT Seeds of bluebunch wheatgrass [Psuedoroegneria spicata (Pursh) A. Love] and Sandberg bluegrass (Poa secunda Presl.) were fed to Holstein heifers in different amounts to investigate the effects of seed feeding level and seed size on the recovery and germinability of passed seed. Animals were fed 60,000, 30,000,15,000, and 7,500 seeds of each species. Passed seeds were recovered from dungcollected daily over a 4-day period and tested for germinability. In general,recovery of the largerseeded bluebunch wheatgrass and the smaller-seeded Sandberg bluegrass declined as seed feeding levels decreased from 60,000 to 7,500 seeds per animal, and as time after seed ingestion increased from 1 to 4 days. Total seed recovery over the 4-day period was greater for bluebunch wheatgrass at the 60,000 seed feeding level, similar for both species at the 30,000 seed feeding level, and greater for Sandberg bluegrass at the 15,000 and 7,500 seed feeding levels.Germinability of bluebunch wheatgrass seeds decreased with each additional day in the digestive tract, while germinability of Sandberg bluegrass seeds remained constant or increased with time. Germinability of both species tended to increase as seed feeding levels decreased from 60,000 to 15,000 seeds per animal. Sandberg bluegrass seeds had greater germinability than bluebunch wheatgrass at all seed feeding levels and collection dates. Recovered seeds had significantly lower germinability than noningested seeds for both species.Results showed that livestock have the potential for dispersing enough germinable seeds on degraded rangelands.

... id="C5">种子消化道传播(seed endozoochore dispersal)是指植物种子被食草(果)动物采食, 经过消化道作用以后, 通过反刍或粪便排出体外从而实现传播的现象(Oudtshoorn & Rooyen, 1998), 动物对植物种子的消化道传播是种子实现远距离传播的重要方式.种子由于动物采食、经消化道携带和排泄而产生空间上的大尺度位移, 一方面为植物种群开拓新栖息地创造了有利条件、避免了同胞间激烈的竞争, 另一方面大大增加了空间尺度上的景观多样性(Heidrun & Oliver, 2008).目前关于草食动物对植物种子消化道传播的研究, 所涉及的动物种类有牛(Willms et al., 1995)、绵羊(Ramos et al., 2006)、山羊(Mancilla-Leytón et al., 2012)、马(Miloti? & Hoffmann, 2016)和驴(Couvreur et al., 2005)等放牧家畜.研究的生态类型包括森林(Jaroszewicz, 2013)、草原(Myers et al., 2004)和沼泽(Brochet et al., 2010)等.具体研究内容包括: 种子自身形态学特征与种子被消化道作用后的回收率、活力以及在消化道内的滞留时间之间的关系(Blackshaw & Rode, 1991), 排出后的种子萌发所形成的幼苗的生长状况以及消化道传播对植被更新过程的影响(Plumptre, 2003), 并且基于上述研究内容可进一步探讨植物与草食动物二者之间是否存在协同进化(D’Hondt & Hoffmann, 2011). ...
