Spermatocysts stained positively with anti-pHH3 antibody
<p>Males have the ability to compete for fertilizations through both pre-copulatory and post-copulatory intrasexual competition. Pre-copulatory competition has selected for large weapons and other adaptations to maximize access to females and mating opportunities while post-copulatory competition has resulted in ejaculate adaptations to maximize fertilization success. Negative associations between these strategies support the hypothesis that there is a trade-off between success at pre- and post-copulatory mating success. Recently, this trade-off has been demonstrated with experimental manipulation. Male leaf-footed cactus bugs, <i>Narnia femorata</i>. Males of this species can lose their hind limbs, their primary weapon in male-male competition, by autotomy during development. Weaponless males invest instead in large testes. While evolutionary outcomes of the trade-offs between pre- and post-copulatory strategies have been identified, less work has been done to identify proximate mechanisms by which the trade-off might occur, perhaps because the systems in which the trade-offs have been investigated are not ones that have the molecular tools required for exploring mechanism. Here we applied knowledge from a related model species for which we have developmental knowledge and molecular tools, the milkweed bug <i>Oncopeltus fasciatus</i>, to investigate the proximate mechanism by which autotomized <i>N. femorata</i> males developed larger testes. Autotomized males had evidence of a higher rate of transit amplification divisions in the spermatogonia, which would result more spermatocytes and thus in greater sperm numbers. Identification of mechanisms underlying a trade-off can help our understanding of the direction and constraints on evolutionary trajectories and thus the evolutionary potential under multiple forms of selection.</p>

Two new species of the Lycophyte Genus Selaginella (Selaginellaceae) from China, with notes on phylogenetic position of related species
<p>Two new species of lycophytes, <em>Selaginella obovata</em> and <em>S. zhangii</em>, were discovered in southeastern Yunnan, China. <em>Selaginella obovata</em> is characterized by the prostrate habit and relatively small size of plant, obovate median leaves, and short, dorsiventral strobili, and is not apparently similar to any known species. Phylogenetic analyses of plastid sequences (<em>rbcL</em>, <em>atpI</em>, <em>psbA</em>) indicated that <em>S. obovata</em> is closely allied to <em>S. bisulcata</em>, which is also supported by spore morphology, and that these two taxa together with <em>S. pennata</em> constitute a well-supported monophyletic group. <em>Selaginella zhangii</em> is comparable to <em>S. rolandi-principis</em> in their broad stems (including leaves) and shape and arrangement of vegetative leaves; but the former differs from the latter in its prostrate habit and dorsiventral strobili. The result of phylogenetic analyses showed indicate that <em>S. zhangii</em> is allied to <em>S. heterostachys</em> in the <em>S. heterostachys–S. ciliaris</em> clade, while <em>S. rolandi-principis</em> is distantly placed in the <em>S. doederleinii–S. involvens</em> clade. Finally, we provide comprehensive descriptions, photographs of living plants, line drawings, and scanning electron micrographs of spores to facilitate their recognition.</p>

Data from: Rapid and positive responses of plants to lower predictability in precipitation
Current climate change is characterized by an increase in weather variability, which includes altered means, variance and predictability of weather parameters, and which may affect an organism's ecology and evolution. Few studies experimentally manipulated the variability of weather parameters, and very little is known about effects of changes in the intrinsic predictability of weather parameters on living organisms. Here we experimentally tested effects of differences in intrinsic precipitation-predictability on two herbaceous plants (Onobrychis viciifolia and Papaver rhoeas). Lower precipitation predictability led to phenological advance and to an increase in reproductive success, and population growth. Both species exhibited rapid transgenerational responses in phenology and fitness-related traits across four generations that mitigated most effects of precipitation-predictability on fitness proxies of ancestors. Transgenerational responses appeared to be the result of changes in phenotypic plasticity rather than local adaptation. They mainly existed with respect to conditions prevailing during early, but not during late growth, suggesting that responses to differences in predictability during late growth might be more difficult. The results show that lower short-term predictability of precipitation positively affected fitness, that rapid transgenerational responses existed, and that different time-scales of predictability (short-term, seasonal, and transgenerational predictability) may affect organisms differently. This shows that the time-scale of predictability should be considered in evolutionary and ecological theories, and in assessments of the consequences of climate change.
