A listing of some 330 algal taxa found in the plankton of the Bay of Quinte during 1975 has been compiled and an indication given of the relative abundance at each of the eight sampling locations. Some difficulties related to interpretation of data on species number or 'richness' are discussed. It is suggested that particular attention in future years be given to several little-known taxa whose distribution and abundance will likely change should the trophic state of the Bay of Quinte be altered. Several species found in the Quinte collections have been only rarely reported from other parts of the world. Taxonomic notes on some problematical or otherwise interesting forms are included.

Abstract. During the last fifty years ecology has matured as a scientific discipline. In this paper I analyse the temporal development of the paradigm based on physical systems (the ecosystem paradigm), and the evolutionary ecology paradigm. I first analyse the contents of 61 textbooks to calculate the relative importance of ecosystem and evolutionary ecology in the training of new generations of ecologists. Results indicate that the evolutionary approach is becoming more important since 1980, and now most textbooks dedicate 10–20% of their pages to evolutionary concepts. In a second analysis I searched the names of ecology departments in universities around the world, and found out conspicuous differences between USA, where 43% of addresses associate ecology and evolution or behaviour on the same department, and Europe, where only 10% of ecology departments also include a reference to evolution or behaviour in their name. In both analyses Spain seems to follow only the ecosystem paradigm, because Spanish textbooks dedicate almost no pages to evolutionary concepts, and there is not a single university department that includes ecology and evolution. A further bibliometric study confirmed that Spanish ecologists prefer to publish their research in general ecology journals, and are under-represented in evolutionary ecology journals. I discuss the importance of historical factors on the development of paradigms of ecology, and the special case of Spain, likely due to the influence of pioneers working in oceanography, limnology and geography.

The practices of vocal music described in this chapter reflect major differences in cultural thinking, comparing those of non-literate societies with that of the West. The rise of vocally based noise music in popular entertainment is discussed as an example of an ersatz form of cultural behavior. The relative importance of acoustic analysis and socio-cultural contexts in the explanation of vocal practices is discussed. It cannot be claimed that a more sophisticated science or mathematics has produced a more powerful or efficient mode of vocal expression. Each cultural system and set of vocal practices has its own integrity and its own relevance to understanding the human condition, and it is only by studying the different vocal practices from within such contexts that their value to humanity as a whole can be appreciated.

AbstractXavier, J. C., Phillips, R. A., and Cherel, Y. 2011. Cephalopods in marine predator diet assessments: why identifying upper and lower beaks is important. – ICES Journal of Marine Science, 68: 1857–1864. Cephalopods are components of the diet of many predators worldwide. They are identified mainly using their chitinized upper and lower beaks, but because it has been assumed that the number of upper and lower beaks would be the same in predator diet samples, more effort has been put into creating keys for the lower beaks, which are more easily identifiable from morphology. A test is made of whether the number of upper and lower beaks differs in diet samples collected from a major cephalopod predator, the wandering albatross (Diomedea exulans), potential biases in the estimation of predator diets are assessed, and upper:lower beak ratios in published studies of other seabirds, seals, whales, and fish from different parts of the world reviewed. The ratio of upper to lower beaks in diet samples from wandering albatrosses varied greatly in a single year (from 69.6% more lower beaks to 59% more upper beaks), and between years (from 0.5 to 32.1% more upper beaks), and biases were greater for certain cephalopod species, resulting in underestimation of their relative importance. Future studies need to consider using both upper and lower beaks to improve the assessment of the contribution of different cephalopods to predator diets.

Governments around the world have introduced a number of stringent policies to try to contain COVID-19 outbreaks, but the relative importance of such measures, in comparison to the community response to these restrictions, the amount of testing conducted, and the interconnections between them, is not well understood yet. In this study, data were collected from numerous online sources, pre-processed and analysed, and a number of Bayesian Network models were developed, in an attempt to unpack such complexity. Results show that early, high-volume testing was the most crucial factor in successfully monitoring and controlling the outbreaks; when testing was low, early government and community responses were found to be both critical in predicting how rapidly cases and deaths grew in the first weeks of the outbreak. Results also highlight that in countries with low early test numbers, the undiagnosed cases could have been up to five times higher than the officially diagnosed cases. The conducted analysis and developed models can be refined in the future with more data and variables, to understand/model potential second waves of contagions.

Manaus, a city of more than two million people, suffers problems arising from strong sunlight and aggravated by several factors, such as traffic congestion and greenhouse gas emissions generated by evaporation and burning of fuel. The present study examined Carbon Monoxide (CO) and Nitrogen Dioxide (NO2) emissions in an urban area of the city using different methodologies. CO and NO2 were measured using automated and passive analyzers, respectively. Meanwhile, direct monitoring of these pollutants was performed in vehicular sources in the vicinity of sampling locations. Results showed that levels of carbon monoxide vary over time, being higher during peak movement of vehicles. NO2 values have exceeded the recommendations of the World Health Organization (WHO), and monitoring at source showed high levels of CO and NO2 emissions to the atmosphere.

AbstractTigers Panthera tigris face a wide and complex array of threats. Given limited time and resources it is essential to direct conservation actions based on the relative importance of each threat. The Sundarbans Reserve Forest is the last stronghold of tigers in Bangladesh and supports one of the largest populations of tigers in the world. As in other tiger landscapes, the threats faced by the tigers have yet to be assessed. This study follows an approach developed by The Nature Conservancy to identify and prioritize threats and set a time-frame for their reduction. We identified a total of 23 threats; four were linked to tigers, two to prey and 17 to habitat. Of the identified threats, the highest ranked included poaching of tigers, poaching of prey, sea-level rise, upstream water extraction/divergence, wood collection, fishing, and harvesting of other aquatic resources. All threats were then scheduled for reduction, based on the rank and current information base for each threat and the likely time-frame for implementing potential solutions. This study demonstrates how the application of a prioritization framework can greatly improve the focus and likelihood of success of any species- or ecosystem-based conservation programme.

In recent years bowl traps have gained attention as a useful method for sampling bees and are now commonly used across the world for this purpose. However, specific questions about the method itself have not yet been tested on different regions of the globe. We present the preliminary results of bowl trapping in a Semidecidual Seasonal forest fragment in southern Brazil, including the test of two different color bowls, two different habitats, and the interaction of these variables in bee species number and composition. We used blue and yellow bowls in the border and in the core trails of the forest fragment. In five sampling days between October to December bowl traps captured 745 specimens of 37 morphospecies, with Halictinae bees being the richest and most abundant group. Non parametrical statistical analyses suggested that different colors of bowl traps influenced bee richness and composition and thus, they should be used together for a more complete sampling. Different trails influenced only the composition, while the interaction with different colors did not have a significant effect. These results, as well as the higher taxonomic composition of the inventoried bees, are similar to other studies reported in the literature.
