Summary
Acanthemblemaria crockeri exhibits a resource defense polygyny mating system with male parental care. Females preferred to mate with the larger of two males in laboratory experiments, and male size was positively correlated with the number of eggs defended by males at two sites in the Gulf of California, Baja California, Mexico. Females appeared to avoid mating with males defending heavily-fouled shelters. The role of other factors including the intensity of male courtship coloration and displays in determining male reproductive success was studied in Bahia San Carlos, Sonora, Mexico by providing glass vials as shelters. This provided a non-destructive technique for counting of eggs defended by males and allowed repeated assessment of the reproductive success of individual males. Males varied greatly in their duration of residency of shelters and in their color score and intensity of courtship displays. The number of eggs received by males was positively correlated with their duration of residency in shelters, and females appeared to avoid mating with new residents. Mated males deserted shelters less frequently and were more likely to receive future matings than were unmated males. The mean color score of males was unrelated to their reproductive success, while the intensity of male courtship displays was negatively correlated with the number of eggs received. This may have resulted because female mate choice is based on multiple criteria, including some that more accurately reflect the quality of parental care afforded by males. 相似文献

This article provides a perspective on nature-based solutions. First, the argument is developed that nature-based solutions integrate social and ecological systems. Then, theoretical considerations relating to relational values, multifunctionality, transdisciplinarity, and polycentric governance are briefly outlined. Finally, a conceptual model of the social–ecological system of nature-based solutions is synthesised and presented. This conceptual model comprehensively defines the social and ecological external and internal systems that make up nature-based solutions, and identifies theoretical considerations that need to be addressed at different stages of their planning and implementation The model bridges the normative gaps of existing nature-based solution frameworks and could be used for consistent, comprehensive, and transferable comparisons internationally. The theoretical considerations addressed in this article inform practitioners, policymakers, and researchers about the essential components of nature-based solutions. The conceptual model can facilitate the identification of social and ecological interconnections within nature-based solutions and the range of stakeholders and disciplines involved. 相似文献

Plastics are dominant pollutants in freshwater ecosystems worldwide. Scientific studies that investigated the interaction between plastics and freshwater biodiversity are incipient, especially if compared to the marine realm. In this review, we provide a brief overview of plastic pollution in freshwater ecosystems around the world. We found evidence of plastic ingestion by 206 freshwater species, from invertebrates to mammals, in natural or semi-natural ecosystems. In addition, we reported other consequences of synthetic polymers in freshwater ecosystems—including, for instance, the entanglement of animals of different groups (e.g., birds). The problem of plastic pollution is complex and will need coordinated actions, such as recycling programs, correct disposal, stringent legislation, regular inspection, replacement of synthetic polymers with other materials, and ecological restoration. Current information indicates that the situation in freshwater ecosystems may be as detrimental as the pollution found in the ocean, although highly underappreciated.Supplementary InformationThe online version of this article (10.1007/s13280-020-01496-5) contains supplementary material, which is available to authorized users. 相似文献
