Data from: Keystone individuals alter ecological and evolutionary consumer-resource dynamics
Intraspecific variation is central to our understanding of evolution and ecology, but these fields generally consider either the mean trait value or its variance. Alternatively, the keystone individual concept from behavioral ecology posits that a single individual with an extreme phenotype can have disproportionate and irreplaceable effects on group dynamics. Here, I generalize this concept to include non-behavioral traits and broader ecological and evolutionary dynamics. I test for the effects of individuals with extreme phenotypes on the ecology and evolution or a gall-forming fly and its natural enemies that select for opposite gall sizes. Specifically I introduce a putatively keystone predator-attracting individual gall-maker, hypothesizing that the presence of such an individual should (i) increase gall-maker population-level mortality, (ii) cause consumer communities to be dominated by species that are most attracted to the keystone individual, (iii) increase selection for traits conferring defense against the most common consumer, and (iv) weaken patterns of stabilizing selection. I find support for both the ecological and evolutionary consequences of single individuals with extreme phenotypes, suggesting that they can be considered keystone individuals. I discuss the generality of the keystone individual concept, suggesting likely consequences for ecology and evolution.
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>
