“…In the Sonoran Desert, batpollinated cactus species are known to adapt to both bird and bat pollinators (i.e., become more generalized) (Fleming et al, 2001). (Schrire, 2005), and many species are pollinated specifically by birds or bats (Agostini, Sazima, & Sazima, 2006;Cotton, 2001;Grünmeier, 1993;Hopkins & Hopkins, 1993;Sazima, Buzato, & Sazima, 1999). However, plants pollinated by multiple mammals are found only in Asia Kobayashi et al 2017;Toyama et al, 2012).…”

Floral traits are adapted by plants to attract pollinators. Some of those plants that have different pollinators in different regions adapt to each pollinator in each region to maximize their pollination success. Mucuna macrocarpa (Fabaceae) limits the pollinators using its floral structure and is pollinated by different mammals in different regions. Here, we examine the relationships between floral traits of M. macrocarpa and the external morphology of mammalian pollinators in different regions of its distribution. Field surveys were conducted on Kyushu and Okinawajima Island in Japan, and in Taiwan, where the main pollinators are the Japanese macaque Macaca fuscata, Ryukyu flying fox Pteropus dasymallus, and red‐bellied squirrel Callosciurus erythraeus, respectively. We measured the floral shapes, nectar secretion patterns, sugar components, and external morphology of the pollinators. Results showed that floral shape was slightly different among regions and that flower sizes were not correlated with the external morphology of the pollinators. Volume and sugar rate of nectar were not significantly different among the three regions and did not change throughout the day in any of the regions. However, nectar concentration was higher in Kyushu than in the other two regions. These results suggest that the floral traits of M. macrocarpa are not adapted to each pollinator in each region. Although this plant limits the number of pollinators using its flower structure, it has not adapted to specific mammals and may attract several species of mammals. Such generalist‐like pollination system might have evolved in the Old World.

“…Furthermore, we strongly encourage future landscape genetic research to focus on how habitat fragmentation and loss might compound overall habitat decline by affecting bird species that play important roles in maintaining such habitats (e.g. Wenney & Levey 1998, Van Bael et al 2003, Agostini et al 2006. Landscape genetics cannot adequately investigate these roles through the study of non-avian species, with the possible exception of bats, studies of which are also relatively few in landscape genetics.…”

Landscape genetics is a rapidly growing discipline that examines how heterogeneous landscapes and other environmental factors influence population genetic variation. We conducted a systematic review of the landscape genetic literature which demonstrates that birds are severely under-represented relative to their species diversity and general publication prevalence. Most avian studies were on species that have relatively low dispersal ability, and we suggest that this reflects an assumed high vagility of birds that precludes spatial genetic variation relatable to landscape heterogeneity. However, spatial genetic variation exists in several bird species with very high dispersal ability, but this has not been considered in the context of landscape features. Genetic patterns may also relate to landscape due to breeding habitat selection and territorial behaviour, despite the fact that species may be able to move throughout different landscape elements with minimal movement costs. Habitat loss and fragmentation are continuing globally and are strongly related to declines in bird populations. Landscape genetic studies provide a means to understand, predict and mitigate the effects of anthropogenic landscape change on birds. This review promotes the need for landscape genetic studies of birds, such that a greater understanding of the drivers of their genetic structuring can be developed and generalizations can be made from landscape genetic studies that apply more broadly across taxa.

Abstract:The study of plant-pollinator interactions is a major tool for conservation biology of fragmented habitats like the Atlantic Rain Forest and for the study of evolutionary traits that rule these interactions. Information on reproductive biology and floral visitor interactions of Sophora tomentosa and Crotalaria vitellina (Fabaceae) is presented in this study. Both species are common in the restinga formation of the Atlantic Rain Forest in the Núcleo Picinguaba, Parque Estadual da Serra do Mar, Ubatuba -São Paulo. These species occur in the same areas, the flowering period is the same for both and they have yellow flowers that offer nectar as the major reward. Both are self-compatible, although fruit and seed set depend on the pollinators. Xylocopa brasilianorum and Megachile sp.1 were pollinators of S. tomentosa, whereas C. vitellina was pollinated by both the aforementioned bees and Bombus morio, Centris labrosa and two separate species of Megachile. All these bees have long tongues and are able to reach nectar at the bottom of the nectar chamber by legitimate visits. The inflorescences of S. tomentosa received more visits (0,62 visits/inflorescence/day) than the inflorescences of C. vitellina (0,37 visits/inflorescence/day). However, the fruit set of S. tomentosa (33%) is similar to that of C. vitellina (42%) in natural conditions, probably due to different pollinator efficiency. Having shorter tongues, Trigona and Augochlora bees have no access to the nectar chamber by means of legitimate visits. Hence, the dimensions of the nectar chamber of S. tomentosa and C. vitellina act as a selective barrier to short-tongued bees, thus guaranteeing more nectar to the long-tongued visitors. These legume pollinators are very common in the restinga forest, and they act as pollen vectors of other species in this ecosystem as well. The preservation of these legume plants is important to the diversity of bees and essential to the plant community. Resumo: O conhecimento das interações entre plantas e seus polinizadores tem-se destacado como ferramenta na biologia da conservação de ambientes degradados, como a Mata Atlântica e no estudo da evolução de características morfológicas que medeiam estas interações. Neste estudo são apresentadas informações sobre a biologia reprodutiva e as interações com os visitantes florais de Sophora tomentosa e Crotalaria vitellina (Fabaceae), espécies comuns em áreas de restinga na Mata Atlântica no Núcleo Picinguaba, Parque Estadual da Serra do Mar, Ubatuba -São Paulo. Estas espécies são sincronopátricas, possuem flores amarelas dispostas em racemos e oferecem néctar como principal recurso. Ambas as espécies são autocompatíveis, mas dependem de polinizadores para formação de frutos e sementes. Xylocopa brasilianorum e Megachile sp.1 foram os polinizadores de S. tomentosa, ao passo que C. vitellina, além destas espécies, também foi polinizada por Bombus morio, Centris labrosa e mais duas espécies de Megachile. Estas espécies de abelhas possuem comprimento da língua compatível com as dim...
