1. Can plant hybridization and polyploidy lead to pollinator shift?
ABSTRACT Events of both hybridization and polyploidy are capable of completely restructuring the genome, modifying phenotypic traits and affecting ecological interactions. For plants, these changes may affect floral traits that are important for interactions with pollinators, which could lead to shifts in pollinator behavior and taxa between hybrids/polyploi

2. Environmental education program in Ecuador: theory, practice, and public policies to face global change in the Anthropocene
Resumo Em 2008, a nova Constituição do Equador reconheceu os Direitos da Natureza para restaurar a pegada ecológica. Por esse motivo, o objetivo principal deste artigo é refletir sobre as teorias, práticas e políticas públicas desenvolvidas nas escolas equatorianas com o Programa de Educação Ambiental ‘Terra de Todos’. Como resultado, este traba

3. Extension of the geographic distribution of Plecturocebus baptista (Pitheciidae, Primates) and a possible hybrid zone with Plecturocebus hoffmannsi: evolutionary and conservation implications
RESUMO Macacos zogue-zogue (família Pitheciidae) são primatas neotropicais altamente diversificados em morfologia, ecologia e genética, com distribuição geográfica abrangente, incluindo a Floresta Amazônica, Mata Atlântica, Cerrado, Pantanal e a Caatinga. Essa diversificação, juntamente com lacunas de conhecimento, gera incertezas na taxonomia e di

4. Holobionts and their hologenomes: Evolution with mixed modes of inheritance
Abstract Symbioses are ubiquitous and have played an influential role in the evolution of life on Earth. Genomic studies are now revealing a huge diversity of associations among hosts and their microbiotas, allowing us to characterize their complex ecological and evolutionary dynamics. The different transmission modes and the asynchronous cell proliferation

5. Long-wavelength sensitive opsin (LWS) gene variability in Neotropical cichlids (Teleostei: Cichlidae)
ABSTRACT Cichlid fishes are an important group in evolutionary biology due to their fast speciation. This group depends widely of vision for feeding and reproduction. During the evolutionary process it plays a significant role in interspecific and intraspecific recognition and in its ecology. The molecular basis of vision is formed by the interaction of the

6. Análisis ecológico de una red empresarial de turismo
ABSTRACT Objective: Institutionalism as an adaptation theory has contributed to understanding of the changing characteristics in governance structures. At the same time, community ecology has enhanced the evaluation of change within organizational communities. This study aims to analyze the relations and interactions of a business network, using institutio

7. Bats and zoonotic viruses: can we confidently link bats with emerging deadly viruses?
An increasingly asked question is 'can we confidently link bats with emerging viruses?'. No, or not yet, is the qualified answer based on the evidence available. Although more than 200 viruses - some of them deadly zoonotic viruses - have been isolated from or otherwise detected in bats, the supposed connections between bats, bat viruses and human diseases h

8. Autoecology of Dryadosaura nordestina (Squamata: Gymnophthalmidae) from Atlantic forest fragments in Northeastern Brazil
Life history parameters such as diet, reproduction, and sexual dimorphism are crucial to understand ecological and evolutionary forces shaping species traits. Nevertheless, such information is scant in the literature for most Neotropical squamates. Gymnophthalmidae contains over 242 species in 46 genera and includes small-size, mostly terrestrial species, al

9. Proliferación subdisciplinar en biología, debacle del reduccionismo y nuevas estrategias de unificación
Over the last decades, in biology there has been a proliferation of subdisciplines and theories, and this poses a question about its unity. Consequently, after reductionism was abandoned as a unifying strategy, philosophical questions have been raised about the possibility of alternative forms of relations among the subdisciplines, and whether they can effec

10. Mad, bad and dangerous to know: the biochemistry, ecology and evolution of slow loris venom
Only seven types of mammals are known to be venomous, including slow lorises (Nycticebus spp.). Despite the evolutionary significance of this unique adaptation amongst Nycticebus, the structure and function of slow loris venom is only just beginning to be understood. Here we review what is known about the chemical structure of slow loris venom. Research on a

11. Padrões bioenergéticos das aranhas de teia: considerações sobre a unidade e a diversidade do fenômeno / Patterns of bioenergetic of web spiders: considerations about the unity and diversity of the phenomenon
The physiological mechanisms are often applied to explain important evolutionary adaptations (e.g. endothermy) and ecology (e.g. physiological limitations to occupy a particular microhabitat) of vertebrates. Despite the fact that it improves vertebrates ecological and evolutionary hypotheses with possible processes and mechanisms, it is scarcely used to unde

12. What can we learn from confusing Olivella columellaris and O. semistriata (Olivellidae, Gastropoda), two key species in panamic sandy beach ecosystems?
Olivella columellaris (Sowerby 1825) and O. semistriata (Gray 1839) are suspension-feeding, swash-surfing snails on tropical sandy beaches of the east Pacific. While they often are the numerically dominant macrofaunal element in their habitats, their biology is poorly understood; the two species actually have been confused in all of the few publications that
