Individual flowering phenology shapes plant-pollinator interactions across ecological scales affecting plant reproduction
<p>1. The balance of pollination competition and facilitation amongst co-flowering plants and abiotic resource availability can modify plant species and individual reproduction. Floral resource succession and spatial heterogeneity modulate plant-pollinator interactions across ecological scales (individual plant, local assemblage, interaction network of agroecological infrastructure across the farm). Intraspecific variation in flowering phenology can modulate the precise level of spatio-temporal heterogeneity in floral resources, pollen donor density and pollinator interactions that a plant individual is exposed to, thereby affecting reproduction.</p> <p>2. We tested how abiotic resources and multi-scale plant-pollinator interactions affected individual plant seed set, modulated by intraspecific variation in flowering phenology and spatio-temporal floral heterogeneity arising from agroecological infrastructure. We transplanted two focal insect-pollinated plant species (<em>Cyanus</em> <em>segetum</em> and <em>Centaurea</em> <em>jacea</em>, n = 288) into agroecological infrastructure (10 sown wildflower, 6 legume-grass strips) across a farm-scale experiment (125 ha).</p> <p>3. We applied an individual-based phenologically explicit approach to match precisely the flowering period of plant individuals to the concomitant level of spatio-temporal heterogeneity in plant-pollinator interactions, potential pollen donors, floral resources and abiotic conditions (temperature, water, nitrogen).</p> <p>4. Individual plant attractiveness, assemblage floral density and conspecific pollen donor density (<em>C</em>. <em>jacea</em>) improved seed set. Network linkage density increased focal species' seed set and modified the effect of local assemblage richness and abundance on <em>C</em>. <em>segetum</em>. Mutual dependence on pollinators in networks increased <em>C</em>. <em>segetum</em> seed set, while <em>C</em>. <em>jacea</em> seed set was greatest where both specialization on pollinators and mutual dependence was high. Abiotic conditions were of little or no importance to seed set.</p> <p>5. Intra- and interspecific plant-pollinator interactions respond to spatio-temporal heterogeneity arising from agroecological management affecting wild plant species reproduction. The interplay of pollinator interactions within and between ecological scales affecting seed set implies a co-occurrence of pollinator-mediated facilitative and competitive interactions among plant species and individuals. </p>
Reproduction ecology of an emerging fishery resource, the amphibious mudskipper Periophthalmus chrysospilos, in the Mekong Delta
<p>The Gold-Spotted mudskipper<i> Periophthalmus chrypsospilos</i> is a potential aquarium pet living in the mudflats in coastal and estuarine regions, but populations of this mudskipper within the Mekong Delta are facing extirpation risks due to indiscriminate harvesting for the growing aquarium and food-fish trade. Consequently, this research aims to provide first reproductive references such as spawning type and season, length at first mature, batch fecundity, being used in conservation and artificially propagation research. Analysis results from 1,031 individuals (523 males and 508 females) reveal that the sex ratio of total individuals recorded is 1:1 (523 males and 508 females) (<i>c<sup>2</sup></i>=0.22, <i>p</i>=0.64). The <i>GSI</i> values are found to exhibit a non-normal distribution (Shapiro-Wilk Test, NJ=0.87, <i>p</i><0.01) and change by gender (Mann-Whitney U, <i>Z</i>=27.04, <i>p</i><0.01), season (<i>Z</i>=6.17, <i>p</i><0.01) and site (Kruskal-Wallis H, <i>c<sup>2</sup></i>=40.72,<i> p<</i>0.01). A combination of <i>GSIs</i> and the monthly appearance of mature gonads suggest that this species reproduces throughout the year, with a peak from July to October. This species exhibits sexual and spatial variation in the size at first maturity (<i>L<sub>m</sub></i>) as <i>L<sub>m</sub></i> is 6.2-8.6 cm in males and 6.4-7.3 cm in females. The batch fecundity (<i>F</i>=2,614 to 23,465 eggs/female) exhibits non-normal distribution (Shapiro-Wilk Test, NJ=0.96, <i>p</i><0.01) and varies with site (Kruskal-Wallis H, <i>c<sup>2</sup> </i>=35.55,<i> p<</i>0.01), reaching the highest point at Dam Doi, Ca Mau (13,336±1,279 SE) and the lowest point at Tran De, Soc Trang (6,654±851 SE). In addition, <i>F</i> is directly proportional to body size due to high determination values of relationships between <i>F</i> and fish size (<i>r<sup>2</sup></i>>0.64 for all cases). Information derived on the reproductive biology of this species can inform its conservation, sustainable exploitation, and ex-situ propagation.</p>
