Allen, Wenfei Tong, Laura Corley Lavine, Brook O. Swanson, Douglas J. Emlen , Evolution of horn length and lifting strength in the Japanese rhinoceros beetle Trypoxylus dichotomus, Current Biology, https://doi.org/10.1016/j.cub.2023.08.066, 2023.09, What limits the size of nature’s most extreme structures? For weapons like beetle horns, one possibility is a tradeoff associated with mechanical levers: as the output arm of the lever system—the beetle horn—gets longer, it also gets weaker. This “paradox of the weakening combatant” could offset reproductive advantages of additional increases in weapon size. However, in contemporary populations of most heavily weaponed species, males with the longest weapons also tend to be the strongest, presumably because selection drove the evolution of compensatory changes to these lever systems that ameliorated the force reductions of increased weapon size. Therefore, we test for biomechanical limits by reconstructing the stages of weapon evolution, exploring whether initial increases in weapon length first led to reductions in weapon force generation that were later ameliorated through the evolution of mechanisms of mechanical compensation. We describe phylogeographic relationships among populations of a rhinoceros beetle and show that the “pitchfork” shaped head horn likely increased in length independently in the northern and southern radiations of beetles. Both increases in horn length were associated with dramatic reductions to horn lifting strength—compelling evidence for the paradox of the weakening combatant—and these initial reductions to horn strength were later ameliorated in some populations through reductions to horn length or through increases in head height (the input arm for the horn lever system). Our results reveal an exciting geographic mosaic of weapon size, weapon force, and mechanical compensation, shedding light on larger questions pertaining to the evolution of extreme structures.

Makoto Ehara, Kimihiko Hyakumura, Ren'ya Sato, Kiyoshi Kurosawa, Kunio Araya, Heng Sokh, Ryo Kohsaka, Addressing Maladaptive Coping Strategies of Local Communities to Changes in Ecosystem Service Provisions Using the DPSIR Framework, Ecological Economics, 10.1016/j.ecolecon.2018.03.008, 149, 226-238, 2018.07, The Driver-Pressure-State-Impact-Response (DPSIR) framework has been applied to various environmental problems at multiple spatial and temporal scales and attempts have been made to conceptually improve the framework to encompass various stakeholder perspectives. However, recent literature experiences in the field have challenged the inclusive character of the framework applications. In particular, the framework's inability to incorporate the aggregated informal responses of people affected by changes in ecosystem service provisions has not been fully addressed. This limits the framework's validity in categorizing and disseminating information for addressing particular environmental challenges. Herein, we address this problem by analyzing a case study of deforestation and its impact on non-timber forest product collections by rural residents in Cambodia. We incorporate the concept of maladaptive coping strategies into the DPSIR framework and then further elaborate Ness et al.'s (2010) approach of merging the DPSIR framework with Hägerstrand's (2001) system of nested spatial domains. This conceptualizes the incorporation of the aggregated informal responses into the system, as exemplified in the case study..

Yuta Ito, Ayane Harigai, Moe Nakata, Kunio Araya, Hosoya Tadatsugu, Teruyuki Niimi, The role of doublesex in the evolution of exaggerated horns in the Japanese rhinoceros beetle, EMBO REPORTS, 10.1038/embor.2013.50, 14, 6, 561-567, 2013.04, Male‐specific exaggerated horns are an evolutionary novelty and have diverged rapidly via intrasexual selection. Here, we investigated the function of the conserved sex‐determination gene doublesex (dsx) in the Japanese rhinoceros beetle (Trypoxylus dichotomus) using RNA interference (RNAi). Our results show that the sex‐specific T. dichotomus dsx isoforms have an antagonistic function for head horn formation and only the male isoform has a role for thoracic horn formation. These results indicate that the novel sex‐specific regulation of dsx during horn morphogenesis might have been the key evolutionary developmental event at the transition from sexually monomorphic to sexually dimorphic horns..
