Diversity and distribution of flower coloration is a puzzling topic that has been extensively studied, with multiple hypotheses being proposed to account for the functions of coloration, such as pollinator attraction, protection against herbivory, and prevention of damage by ultraviolet light. Recent methodologies have allowed studies to consider the visual system of animals other than humans, helping to answer questions regarding the distribution of flower coloration. A survey of keywords in Web of Science shows floral color to be mainly studied in relation to macroevolutionary traits and biochemistry of pigments, focusing on pollination and anthocyanins, respectively. The present paper reviews mechanisms that determine the color of flowers. First, it is discussed how pigment, visual systems and signaling environments influence flower color; secondly, patterns of convergent evolution of flower color is debated, including evolutionary history, pollinator preference, flower color change, flowering season, and habitat. Third and last, patterns of flower coloration that have been found around the globe are addressed. In short, the aim is to contribute to ongoing research, by underlining mechanisms that lead to global patterns of coloration and indicating perspectives for future study on the topic.
花颜色的多样性和分布是一个令人困惑的话题，已经被广泛研究，提出了多种假设来解释颜色的功能，如吸引传粉者、防止草食和防止紫外线的伤害。最近的方法使研究能够考虑除人类以外的动物的视觉系统，有助于回答有关花卉颜色分布的问题。Web of Science检索的关键词显示，花的颜色研究主要集中在与大进化性状和色素生物化学相关的方面，主要集中在授粉和花青素方面。本文综述了决定花朵颜色的机制。首先，讨论了色素、视觉系统和信号环境如何影响花的颜色;其次，讨论了花色趋同进化的模式，包括进化史、传粉者偏好、花色变化、开花季节和生境。第三，也是最后，已经在全球范围内发现的花卉颜色模式被解决。简而言之，目的是促进正在进行的研究，通过强调导致全球模式的机制，并指出未来研究该主题的观点。

Bryaceae is a species-rich moss family comprising ten genera and 660 species, with four genera and 54 species occurring in Brazil. Bryum is the largest genus, with 440 cosmopolitan species, while Anomobryum comprises 47 cosmopolitan species. Identifying taxa in Bryaceae is usually a difficult task, mainly due to the lack of the sporophyte in herborized specimens. This study aimed to provide a taxonomic treatment for the species of Anomobryum and Bryum in Brazil. Field expeditions were performed in all Brazilian biomes and States, with specimens deposited in the SP herbarium. We examined type specimens and collections from national and international herbaria, but mostly from the SP herbarium. Two species of Anomobryum and 18 species of Bryum were recorded for Brazil. Twenty species occur in the Atlantic Forest, with Bryum pallescens , Anomobryum conicum and A. julaceum being exclusives. Bryum pallescens is a new record for Brazil, and B. riparioides is a reestablished name also endemic to Brazil. We present the first description of the sexuality of Bryum renauldii . Ten taxa of doubtful occurrence and 20 excluded names for Bryum were reported for Brazil.

Although extrafloral nectaries (EFNs) are reported as extremely important to understand ecological interactions, the diversity of EFN-bearing plants remains underappreciated. In Brazil, studies are concentrated in Cerrado and extremely poorly known in other phytogeographic domains, such as Atlantic forest. Thus, this study provides one of the first checklists of angiosperms with EFNs in a protected area of the Brazilian Atlantic forest, bringing information about the richness, location of EFNs on the plant’s organs, as well as plant’s habit and conservation status. A total of 93 EFN-bearing species belonging to 61 genera and 29 families is reported, which corresponds to 16.5 % of the local flora. The vast majority has not been evaluated for their conservation status, and twenty species are endemic to the Brazilian Atlantic forest. Vines and trees are the predominant plant habits and EFNs are mostly found on leaves. More than half of the species (53.7 %) comprises new additions to the world list of EFN-bearing plants, including the first record in Dilleniaceae. Our findings show a large number of EFN-bearing plant species from a single and small protected area in the Brazilian Atlantic forest. It reinforces the lack of studies of this nature, where further investigations are strongly recommended.

Pannaria hookeri (Borrer ex Sm.) Nyl. is reported as a bipolar cyanolichen that occurs in more than twenty countries in both Hemispheres. In the Northern Hemisphere, a minor variation is attributed to the species, whereas larger morphological and chemical variations have been reported in specimens from the Southern Hemisphere. Six P. hookeri DNA sequences are available in GenBank, and only one (from Australia) is associated with a published morphological description. In this study, we performed a preliminary phylogenetic analysis including seven nuITS and mtSSU sequences from eight specimens collected in south Argentina. In addition, we provide an update of the taxon circumscription based on 50 specimens from 13 countries. Here, the molecular analyses revealed a well-supported monophyletic group formed by the P. hookeri sequences from Argentina, Australia, Norway and USA (Alaska). Regarding the morphological and anatomical characteristics, the Southern Hemisphere specimens did not present the historical reported variations, resulting in the proposition of a concise species description that accomplishes most of P. hookeri known geographical distribution.
帕纳利亚·胡克里(Borrer ex Sm.)Nyl。据报道，它是一种双相蓝藻，在两个半球的20多个国家都有发生。在北半球，该物种的变异较小，而在南半球的标本中报告了较大的形态和化学变异。在GenBank中有6个P. hookeri DNA序列，只有一个(来自澳大利亚)与已发表的形态描述有关。在这项研究中，我们对阿根廷南部采集的8个标本进行了初步的系统发育分析，包括7个nuITS和mtSSU序列。此外，我们还对来自13个国家的50个标本进行了分类群划分的更新。在这里，分子分析显示了一个由阿根廷、澳大利亚、挪威和美国(阿拉斯加)的P. hookeri序列形成的良好支持的单系群。在形态学和解剖学特征方面，南半球标本没有呈现历史报道的变异，因此提出了一个简明的物种描述，完成了大部分已知的hookeri地理分布。

Canga ecosystems develop over superficial iron crusts with shallow and nutrient-poor soils. Under these conditions, arbuscular mycorrhizal fungi (AMF) play an important role in helping plants to overcome abiotic and biotic stresses. Canga can suffer periodic burning and yet it is unknown what the impacts of fire are to AMF communities. We aimed to compare AMF in Canga areas affected by burning (BC) with those with no previous history of burning (NC). We compared AMF species composition, spore numbers, species richness, and mycorrhizal inoculum potential. The total number of spores, AMF species richness and mycorrhizal colonization measured in the infectivity bioassay were not significantly different between areas. A total of 23 species in 10 genera were recovered, with most species belonging to Gigasporaceae and Acaulosporaceae. BC and NC shared 52 % of AMF species. Gigaspora albida, Gigaspora gigantea, and Dentiscutata heterogama sporulated exclusively in trap cultures. We concluded that AMF spore communities were not affected by burning in Canga soils as measured by spore abundance, species richness and infectivity. Our data contribute to the inventory of soil biodiversity associated with Canga, a high biodiverse and threatened Brazilian ecosystem.

Trindade Island has lost much of its original vegetation cover as a result of approximately three centuries of human occupation and intense herbivory caused by invasive mammals. Since the eradication of some of these herbivores, the recovery of some plant species has started. Plantago trinitatis is an endemic herb from Trindade Island, which was considered extinct until 1998, when it was rediscovered in the higher areas of the island. The regeneration of the species was attributed to the soil seed bank. This communication reports new records of P. trinitatis close to sea level on Trindade Island, at lower altitude than previously documented. The new records suggest that P. trinitatis is recolonizing the island, but leaves doubts whether sampling gaps in the past have led to the non-detection of the plant in its vegetative form in these locations, emphasizing that other species considered extinct may share this issue. Regardless of recolonization or sampling gaps, the eradication of invasive herbivores is necessary as a strategy to protect local flora and native vegetation. Understanding the population status can help in making decisions about the need of environmental management and species population recovery.
