Kellicottia Bostoniensis

Processes related to biological invasion of inland waters have become a major issue due to the increasing number of cases associated with the potential effects of invasions. Kellicottia bostoniensis and K. longispina are rotifer species originating from North America and have become invasive in several continents. In this sense, this study carried out a scientometric analysis to analyze the geographical distribution and identify patterns of occurrence as well as to fill gaps on the knowledge of these species. The survey was based on articles indexed in databases from 1896 to 2014. There is a greater scientific knowledge of these species in the temperate region, and these are present in many different environments. In Brazil, there is a very small number of studies, and no record of K. longispina. Therefore, it is noteworthy the importance of studies on the occurrence and abundance of these species in poorly studied areas, such as subtropical and tropical regions, for a better understanding of their invasive potential, given the potential effects on different communities, which can affect the structure and dynamics of environments.

Abstract Jatropha integerrima is a shrub to small tree native to Cuba, which has been introduced into tropical and subtropical areas worldwide as an ornamental species. Although it has become naturalized in some areas, it is not listed as an invasive species. The Center for Invasive Species and Ecosystem Health only lists J. integerrima for comparison with other Jatropha species. J. integerrima can occasionally escape from cultivation in disturbed areas in Florida, and sometimes occurs in warmer parts of Australia. The species has little to no invasive potential in North America and a low invasion risk in Hawaii, USA.

Background Pattern

An ornamental freshwater shrimp, Neocaridina davidi, is popular as an aquarium hobby and, therefore, a potentially invasive species. There is a growing need for proper management of this species to determine not only their optimum breeding conditions, but also their ability to colonise novel environments. We tested habitat preferences of colour morphs (brown, red, white) of N. davidi for substratum colour (black, white, grey shades, red) and fine or coarse chess-board patterns to recognise their suitable captivity conditions and predict their distribution after potential release into nature. We conducted laboratory choice experiments (n = 8) with three individuals of the same morph exposed for two hours to a range of backgrounds. Shrimp preferred dark backgrounds over light ones irrespective of their own colouration and its match with the background colour. Moreover, the brown and red morphs, in contrast to the white morph, preferred the coarse background pattern over the finer pattern. This suggests that the presence of dark, uniform substrata (e.g., rocks, macrophytes) will favour N. davidi. Nevertheless, the polymorphism of the species has little effect on its total niche breadth, and thus its invasive potential.

AbstractMany temperate plant genera, likeSambucus, have species with range disjunctions among North America, Europe and/or Asia. Cold stratification (sometimes in combination with warm stratification) is the primary mechanism to break seed dormancy in these species. For some of these genera showing Northern Hemispheric disjunctions, members also occur in subtropical or tropical regions, mostly confined to higher elevations where climate and vegetation differ from those in northern latitudes. We made two hypotheses concerning germination for the subtropical TaiwaneseSambucus chinensis: (1) seeds from populations exposed to warm temperatures would require warm stratification, and (2) seeds from populations exposed to cold temperatures need cold stratification. We investigated the germination (including embryo growth) of non-stratified seeds over a range of temperatures and tested the effects of cold stratification and of gibberellins GA3and GA4on germination. The amount and timing of germination among populations varied substantially in response to temperature treatments. Seeds from all populations of this species required warm temperatures for dormancy break and germination, regardless of environmental conditions. As such, the majority of seeds had non-deep simple morphophysiological dormancy, which, until now, has not been reported in any members ofSambucus. The seed characteristics of the subtropicalS. chinensisare different from those of temperate members of the genus in which cold stratification is the predominate treatment to overcome dormancy.

Central Concept

The article deals with correspondence in natural history in the eighteenth century between England and North America. The corpus discussed consists of correspondence between John Bartram and Peter Collinson, and between Alexander Garden and John Ellis. The approach used in the study is qualitative and rhetorical; the main point considered is how the letters construct scientific centre and periphery in the eighteenth-century Atlantic world. A central concept is the “colonial exchange”, whereby “raw materials” from the colonies — in this case plant and animal specimens, along with proposed identifications and names — are exchanged for “finished products”, in this case codified scientific knowledge contained in publications.

Limnoperna fortunei (golden mussel) is a freshwater bivalve native to Southeast Asia, but is becoming an invasive species in several aquatic ecosystems in the world. In this study, a scientometric analysis was performed to identify the patterns, trends and gaps of knowledge for this invasive species. A survey of the published literature was conducted using the database of the Thomson Institute for Scientific Information (ISI). A total of 107 papers were surveyed that were published between 1982 and 2012 in 60 journals. The number of papers on L. fortunei over the years has increased, especially within the last eight years of the study period. Argentina, Brazil, and Japan are the countries that contributed the most papers to the literature on invasive bivalve. The majority of papers were field-observational studies. Among some important gaps that need to be addressed are the relatively small number and/or lack of studies conducted in the native countries and in countries invaded by L. fortunei, the lack of internationally collaborative publications in these countries, as well as a low number of internationally collaborative studies.

AbstractInvasive species with distributions that encompass much of the North American environment often demand a range of management approaches, for several key reasons. Firstly, the North American environment includes a large number of highly variable habitats in terms of climatic, edaphic, and landscape features. Secondly, these regional habitat differences are accentuated by jurisdictions within Canada and the United States, whereby approaches and available resources differ at local, regional, and national scales. Another important consideration is whether an invasive species or complex also possesses genetic variation. All three of these factors render the knotweed complex in North America a highly variable target for management. In this paper we review existing knowledge of the variable nature of knotweed species (Fallopia japonica (Houtt.) Ronse Decr., Fallopia sachalinensis (F. Schmidt ex Maxim) Ronse Decr., and Fallopia × bohemica, (Chrtek and Chrtková) J. P. Bailey in North America, and evaluate how herbicidal, mechanical and biological control measures must account for this genetic variation, as well as accounting for regional differences and the potential northward expansion of knotweed under climate change. The imminent release of the psyllid, Aphalara itadori Shinji as a biological control agent in North America must also navigate regional and genetic differences. Prior European experience dealing with the three knotweed species should prove useful, but additional research is needed to meet the emerging challenge posed by F. × bohemica in North America, including the possibility of glyphosate resistance. Managers also face challenges associated with posttreatment restoration measures. Furthermore, disparities in resources available to address knotweed management across the continent need to be addressed to contain the rapid spread of this highly persistent and adaptable species. Linking practitioners dealing with knotweed “on the ground” with academic research is a crucial step in the process of marshalling all available resources to reduce the rapidly spreading populations of knotweed.

Bee populations are declining because of various synergistic threats, and therefore bee survey and monitoring programs are needed. Several techniques have been developed to survey bees, but the most cost-effective and suitable methods to sample bees in several sites at the same time are passive approaches, such as methods involving colored pan traps (also known as Moericke or bowl traps). Several bee surveys using pan traps have been conducted in North America, Europe, and Australia, but only a few such surveys have been done in tropical regions. We used colored pan traps (blue, yellow, and white) to assess the bee community in the Brazilian savanna ecosystem in Rio Preto State Park. Sampling was conducted in October 2013 and March 2014 along permanent trails. We also characterized the local habitat of each trail, and then we compared bee abundance with habitat complexity. In total, 187 individual bees (n = 15 species) were collected, mainly using blue and white traps. Although we were not able to sample most species that were previously recorded in this park, the pan trap method can be used to survey and monitor bee assemblages in combination with another sampling method. Habitat complexity also affected the numbers of bees sampled using the pan traps, and more bees were collected at open sites.

Close Proximity

The scientific contributions of native scholars in the Americas have often been overlooked or neglected. The simultaneous discoveries of European scientists reached a wider audience because of the number of education centers in close proximity. The existence of several scholarly journals also facilitated the rapid dispensation of new scientific knowledge. Although Spanish American scholars lived far from the centers of European knowledge, there was no appreciable time lag between European discoveries and their circulation in Spain's colonies. On the other hand, Spanish American discoveries were unknown in Europe or North America except to a handful of prominent scholars.

A New Species

Brachodidae are a small family of fewer than 140 described species that are distributed worldwide except in North America. They reach their greatest diversity in the tropical regions of Asia and South America; however, many species occur in the Palaearctic region and in Australia, but these are restricted to a small number of genera. More than 40 species are known from the Oriental region and many more await description (Kallies 1998, 2000, 2004).
