A six-year survey of snakes in a tropical coastal rainforest: role of prey and environment. Revista de Biología Tropical, 68(1), 336-343. | The objective of this study was to investigate whether the snake populations in Drake Bay are declining, and whether there is a relationship to preys, weather, temperature, rain, and moonlight. Observations were carried to accumulate 4000 hours, between 2012 and 2017. We found a total of 25 species, within five families, with frequencies decreasing over the years, especially for species that feed on amphibians and reptiles. The number of snake encounters in Drake Bay, Costa Rica, is not affected by light or temperature, but is lower when it doesn’t rain. The decline of snakes in Drake Bay appears to be real and needs the attention of conservation authorities. | |

Biotropic, 0 (0), 1-8. DOI: 10.1111 / btp.12470. | We analyzed the distribution of vascular plant species within across an elevation gradient within La Amistad National Park, to test if river catchment, combined with elevation, explains variation in species composition. Annual mean temperature, elevation, and river catchment variables best explained the variation within local species communities. Only the plots in high-elevation oak forest and páramo were distinct from those in low- and mid-elevation zones. Beta diversity did not significantly differ in plots grouped by elevation zones, except for low-elevation forest, although it did differ between river catchments. Our analysis supports the hypothesis that river catchment can be an alternative means for classifying tropical forest assemblages in conservation settings. | FGB 2017 biotropic moors |

Research Journal of the Costa Rican Distance Education University, 9 (1), 59-64. DOI: 10.22458 / urj.v9i1.1679. | Data on sexual positions and “previous game” are presented based on the observation of videos of intimate encounters of Latin American heterosexual couples. The most frequent positions were «woman on her hands and knees»; «Woman in bed with the man standing,» and «woman sitting on the man.» The most frequent activities were fellatio, manual stimulation of the penis and manual stimulation of the vulva. The longest average durations of particular activities were 67 seconds for intercourse, 37 s for fellatio and 34 s for intimate caresses. These results differ from those reported in the US, possibly due to cultural differences, and the use of objective measurements. This study seems to be the first to «deconstruct» the previous game (foreplay) into its individual components. | JMN 2017 sex meetings |

Biological Reviews, 00 (00). DOI: 10.1111 / brv.12366. | We review studies investigating variation in network structures along environmental gradients, highlighting how methodological decisions about standardization can influence their conclusions.While measures of network structure can be directly related to changes along environmental gradients, standardization is frequently used to facilitate interpretation of variation in network properties by controlling for some co-variables, or via null models.Null models allow comparing the deviation of empirical networks from random expectations and are expected to provide a more mechanistic understanding of the factors shaping ecological networks when they are coupled with functional traits.We compare approaches to quantify the role of trait matching in driving the structure of plant – hummingbird mutualistic networks, ie a direct comparison, standardized by null models and hypothesis ‐ based metaweb.Overall, our analysis warns against a comparison of studies that rely on distinct forms of standardization, as they are likely to highlight different signals.Fostering a better understanding of the analytical tools available and the signal they detect will help produce deeper insights into how and why ecological networks vary along environmental gradients. | |

These results suggest a link between interaction specialization and both phenotypic specialization and floral resource richness within bird – flower communities at a global scale. | |

The environmental education workshop as a didactic strategy to promote the sustainability of natural resources in students of rural Costa Rican primary schools. Research Journal of the Costa Rican Distance Education University, 8 (2), 157-161. | We aimed to evaluate the effect of the Ambietnal Education Workshop on the concordance between the attitude and behavior in favor of the environment in students of rural primary schools in Costa Rica. We did evaluations before and after the workshop, using a Likert-type questionnaire and a correctly classified waste count on an experimental group and a control group. After the workshop, the attitude reported in favor of the environment in the experimental group decreased, but the behavior improved. This result is probably due to the fact that the workshop got the students to analyze more and be more critical when giving their answers. Attitude is only one of the elements that can predict actions; social and knowledge elements also influence.Educational processes based on real problems and «learning by doing» are effective in changing patterns of attitude and behavior, however, the way they change is different. | ZBL 2016 education workshop |

I place King Kong in the historical context, from the Epic of Gilgames , through the sculpture of Emmanuel Frémiet, to the 1933 film. The vegetation of the island and the culture of the natives have a certain likelihood, but not the existence of such large animals on such a small island. The sexual aspect of the relationship between Ann and Kong is not disabled for mechanical reasons but for the script itself. There is documentary evidence that a gorilla would examine a small anthropomorphic object exactly as Kong examines Ann. The different versions of King Kong reflect their respective epochs: escapism during the economic depression (1933); the love of nature and sexual liberation (1976); and the conservative society (2005). | JMN 2016 King-Kong |
| Maglianesi, MA & Jones, G. (2016). Effect of climate change on plant-animal interactions and their consequences on ecosystems. Biocenosis, 30 (1-2), 70-79. | Mutualistic interactions are especially vulnerable to being affected by climate change due to their high sensitivity to phenological decoupling if the interacting species do not respond similarly to environmental changes. In plant-pollinator and plant-seed dispersal interactions, phenological decoupling can affect plants causing reduced reproduction, while seed pollinators and dispersers are affected by reduced food availability. The decline of pollinators and seed dispersers can lead to the loss of interactions in communities, which in turn can lead to the collapse of the ecosystem functions and services they maintain. These consequences could be particularly severe in the tropics, where there is a high dependence on seed pollination and dispersal through animals. | MAM 2016 climate change |

Research Journal of the Costa Rican Distance Education University, 8 (2), 207-216. | All the messages of the InternationalSexGuide.info forum between 2002 and 2015 are analyzed , comparing them with the hypotheses of Megan Rivers-Moore, who carries out the most important study on male sex tourism, the categories of the “Prism of Intimacy” of Milrod and Weitzer and data from the literature on women visiting Costa Rica for sex tourism. The analysis shows that men talk, advising themselves on how to get a satisfactory visit, which includes but is not limited to paid sex Sex workers have little interaction with each other, but men feel part of a group that exchanges useful information. The desire to “be treated as a boyfriend” is not predominant, but it is frequent Most male tourists make short visits where they try to interact initially with several women and then focus on those with whom they felt better. A few cases evolve into a complex relationship that includes emotional commitment. Despite the difference in financial power between clients and providers of sexual services, traditional gender roles underlie relationships, whether they are male or female tourists, which probably reflects a complex combination of biological and cultural factors. | Yes JMN 2016 male sex tourism |

Low values of contamination by chlorides and sulfates were obtained, of the order of 5 mg m-2 day-1 and without significant levels of acid rain, despite being close to an active volcano, indicating a rural-type atmosphere.The humidification time level was of the order of 60%, according to ISO 9223 and 9225, the atmospheric classification is of type C3 category (medium corrosivity). The corrosion rate values obtained for steel show initial levels of the order of 40 μm year-1, stabilizing after 3 years at levels of 20 μm year-1, associated with the formation of protective oxides. The accumulated corrosion complies with the values estimated by the ISO Corroag model of ISO 9226.

DOI: 10.1111 / ecog.01538 | We investigated patterns in functional assemblage structure and specialization of hummingbirds at the individual and species level along a tropical elevational gradient, using the pollen carried by individuals to construct plant – hummingbird networks at different elevation. Hummingbird species and individuals were more specialized at low and mid elevations than at the highest elevation. This pattern corresponds to a more even and over-dispersed assemblage structure at the lower elevations throughout the year and suggests a high level of floral resource partitioning in functionally diversified communities. In contrast, an uneven and clustered functional structure of the highland assemblage across all sampling periods suggests that this assemblage was structured by environmental filtering and by niche expansion of hummingbird individuals and species at this elevation.We conclude that high degrees of specialization on specific floral resources might be crucial for the coexistence of hummingbird species in diversified lowland communities. | Yes MAM 2015 functional structure |

Quercus coccifera seed removal was null in the burned area while in the unburned area the removal occurred since the beginning of the study. It is suggested that greater plant cover favors rodent activity thanks to protection from predators. In the burned area, the low vegetation cover and the presence of acorns gnawed on the ground are indicators of removal of acorns by rodents in the post-dispersive stage. In the case of Smilax aspera, the removal of seeds was slower, and the total loss of fruits due to greater senescence, in the burned area than in the unburned area.

| Maglianesi, M. (2010). Birdlife associated with the native forest and exotic coniferous plantation in the Grecia Forest Reserve, Costa Rica. Neotropical Ornithology, 21, 339-350. | The bird community was characterized in a secondary native forest and a coniferous plantation ( Pinus oocarpa and Cupressus lusitanica ) in the Grecia Forest Reserve, Costa Rica. A total of 743 birds belonging to 79 species were registered, distributed in 10 orders and 25 families. Species composition varied across habitats, sharing 51.9% of bird species. Although there were no significant differences in species diversity and equity between habitats, the native forest had greater wealth and abundance with respect to planting. This could be explained by greater spatial heterogeneity and productivity in the native forest in relation to coniferous planting.It is recommended to gradually replace exotic vegetation with native species that offer more resources for bird populations. | Yes MAM 2010 birdlife Greece |

DOI: 10.1111 / j.1744-7429.2002.tb00554.x | We predicted that (1) fewer seeds would be dispersed by vertebrates in fragmented forest than in continuous forest due to low population abundances after hunting and / or loss of suitable habitat, and (2) seed predation rates would be higher in forest fragments than in continuous forest due to high abundance of small ‐ bodied seed consumers. An exclusion experiment was performed (seeds placed in the open vs. seeds within semipermeable wire cages; 5 cm mesh size) to evaluate the relative roles of large and small animals on seed removal. Our results suggest that fragmentation effects on tree seed fate may be specific to species in question and contingent on the animal biota involved, and that management strategies for timber production based on regeneration from seed may differ between forest patches and extensive forests. | |

There is no evidence that ethological studies are affected by their normally brief duration (one year or less), but the analysis of yearly values hid the associations of number of individuals and arrival time with climate. In small areas, isolated population counts lasting less than two weeks are not reliable, according to this study. We found no difference in number of visitors for El Niño years. The daily number of visitors was inversely correlated with temperature and precipitation, but arrival time of the first visitor was positively correlated with both. Aerial interactions were seen whenever there was more than one individual in the site.Only once in these 22 years was predation seen. | JMN 2000 butterfly |

| Morera-Brenes, B., Monge-Nájera, J. & Saénz, R. (1988). Parturition in onychophorans: new record and a review. Brenesia, 29, 15-20. | A description of the sequence of the birth of a Costa Rican species of Epiperiparus and the characteristics and behavior of the newborn are presented. It is concluded that birth in onychophores presents a relatively constant sequence of events in the taxon.The systematic distribution of the types of reproduction suggests a growing trend towards increasing parental investment. | JMN 1988 mulberry parturition |
| Monge-Nájera, J., Morera-Brenes, B. & Chávez, M. (1988). Nesting behavior of Rhinoclemmys pulcherrima in Costa Rica (Testudines: Emydidae). Herpetological Review, 1, 308-309. | This is the first report on the nesting behavior of the semiaquatic turtle Rhinoclemmys pulcherrima . Similar behavior is found in R. funerea but in the case of R. punctularia and R. diademata no nests are diged, although their eggs soon become inconspicuous as mud and fallen leaves cover them in the wet forest.Nest digging is the rule in R. pulcherrima and might have an adaptive function in the dry environments that it inhabits. | JMN 1988 rhinoclemmys |
| Monge-Nájera, J. & Morera-Brenes, B. (1987). Why is the coyote (Canis latrans) expanding its range? A critique of the deforestation hypothesis. Journal of Tropical Biology / International Journal of Tropical Biology and Conservation, 35 (1), 169-171. | The author rescues mentions dating back to 1526 that possibly refer to the precensia of the coyote in Nicaragua and Guanacaste.Therefore, the narrative about the distribution of coyote in Central America as a result of deforestation is challenged. The reasons that may have restricted its distribution are questioned, and aspects such as dispersal capacity, dam availability and competition with other predators are ruled out.It is concluded that 4 hypotheses or their combinations must be tested to elucidate this enigma. | JMN 1987 coyote expanding |

| Monge-Nájera, J. & Morera-Brenes, B. (1986). The dispersion of the coyote (Canis latrans) and the evidence of the ancient chroniclers. Brenesia, 25-26, 251-260. | It has been proposed that the increase in the scope of distribution of the coyote is the result of deforestation.However, a study of chronicles (1514-1910) shows that the species was already established in Guanacaste in 1514.Coyotes inhabit a great variety of climates and the hypothesis that the high temperatures and rainfall of the Caribbean side prevents them from colonizing is not satisfactory. A more likely barrier is the lack of an adequate combination of dams and open field. | JMN 1986 coyote dispersion |
