Abstract:
A subset of invasive alien plant species in southern Africa was analysed in terms of their history of introduction, rate of spread, countries/region of origin, taxonomy, growth forms, cultivated uses, weed status and current distribution in southern Africa, and comparisons made of those originating from south of the tropic of Capricorn, north of the tropic of Cancer and from the tropics. The subset of 233 species, belonging to 58 families, includes all important declared species and some potentially important species. Almost as many species originate from temperate regions (112) as from the tropics (121). Most southern temperate species came from Australia (28/36), most tropical species from tropical America (92/121) and most northern temperate species from Europe (including the Mediterranean) and Asia (58/76). Transformers account for 33% of all species. More transformers are of tropical origin (36) than of northern temperate (24) and southern temperate origin (18). However. 50% of southern temperate species are transformers, compared to 32% of northern temperate and 29% of tropical species. Southern temperate transformer species are mainly woody trees and shrubs that were established on a grand scale as silvicultural crops, barriers (hedges, windbreaks and screens) and cover/binders. Most aquatics, herbs, climbers and succulent shrubs an. trom the tropics. Ornamentals are the single largest category of plants from all three regions, the tropics having contributed twice as many species as temperate regions.

Abstract:
In Australia’s Wet Tropics rivers, perennial base flows punctuated by wet season floods drive instream responses across a range of spatial and temporal scales. We combined gut-content and stable-isotope analyses to produce preliminary webs depicting trophic links between fish, their main prey items and basal productivity sources. We then used these webs to test the applicability of general food web principles developed in other tropical systems. Although a range of sources appeared to underpin fish productivity, a large portion of total energy transfer occurred through a subset of trophic links. Variability in food web structure was negatively correlated with spatial scale, being seasonally stable at river reaches and variable at smaller scales. Wet Tropics rivers are similar to those in other tropical areas, but exhibit some unique characteristics. Their high degree of channel incision improves longitudinal connectivity, thereby allowing fish to move between mesohabitats and target their preferred prey items, rather than shifting their diet as resources fluctuate. However, this also inhibits lateral connectivity and limits terrestrial energy inputs from beyond the littoral zone.

Abstract:
The Tropics have long been associated with exotic diseases and epidemics. This historical imaginary arose with Aristotle’s notion of the tropics as the ‘torrid zone’, a geographical region virtually uninhabitable to temperate peoples due to the hostility of its climate, and persisted in colonial imaginaries of the tropics as pestilential latitudes requiring slave labour. The tropical sites of colonialism gave rise to urgent studies of tropical diseases which lead to (racialised) changes in urban planning. The Tropics as a region of pandemic, plague and pestilence has been challenged during the COVID-19 pandemic. The novel coronavirus did not (simply) originate in the tropics, nor have peoples of the tropics been specifically or exclusively infected. The papers collected in this Special Issue disrupt the imaginary of pandemics, plague and pestilence in association with the tropics through critical, nuanced, and situated inquiries from cultural history, ethnography, cultural studies, science and technology studies, Indigenous knowledge, philosophy, anthropology, urban studies, cultural geography, literature and film analyses, and expressed through distinctive academic articles, poetry and speculative fiction.

Abstract:
Getting back to the point of “Tropical architecture,” architecture in the humid tropics is collaboration with nature to establish a new order in which human beings may live in harmony with their surroundings. As publications at the time concentrated on French and British colonies, to achieve a comprehensive understanding of the Modern Movement diaspora, it is essential to revisit, analyse, and document the important heritage built south of the Tropic of Cancer, where the debate took place and architectonic models were reproduced, and in many cases subjected to metamorphoses stemming from their antipodal geography. Notable for the modernity of its social, urban, and architectonic programs, and also its formally and technologically sustained research, the modern architecture of these latitudes below the tropics constitutes a distinctive heritage.

Abstract. Temperature changes in the tropics, especially in the tropical tropopause layer, are investigated at the time of a major stratospheric sudden warming (SSW) event that started on about 16 January 2009. During the SSW, the temperature in the tropical upper stratosphere declined and the cold anomaly propagated downward, while the tropics between 150 and 100 hPa started to cool from 18 January, prior to a temperature drop at 70 hPa. We performed thermodynamical and dynamical analyses with ERA-Interim data. During the SSW event, the tropical stratosphere was cooled by upwelling, and the upwelling was induced by wave forcing in the northern extratropical stratosphere. However, the stratospheric wave forcing generated only weak upwelling in the tropics below 100 hPa. During the cooling period at around 18 January, tropical ascent was the main contributor to cooling of the tropics between 150 and 100 hPa. Subsequently, vertical convergence of the vertical heat flux, which is closely tied to the convection structure, resulted in a gradual decrease in temperature within the tropical uppermost troposphere. Waves that had same source region with the upward-propagating waves that caused the SSW event, propagated from Alaska to the tropics of Eastern South America and Eastern Africa at around 100 hPa, and dissipated in these areas; the associated wave forcing drove the tropical ascent between 150 and 100 hPa.

Kata Kunci: arsitektur, mall, tropisABSTRACT.. Indonesia is a country that has a tropical climate. The tropical climate consists of a dry season and a rainy season. In the tropics, the temperature is quite hot and also has high rainfall, so this can have an impact on the adaptation of buildings in the tropics. One of the buildings that is quite important in this modern era is the Shopping Center or Mall which is the place for transactions and buying and selling. To make a mall you also have to pay attention to comfort, especially in a tropical climate, so you need a study of modern architecture in shopping center buildings. This study aims to find out and understand the concept of tropical architecture in Mall buildings. The method used in this study is a qualitative descriptive method with a case study of Transmart Cibubur. As a result, Transmart Cibubur has a canopy and double façade on the front of the building. To create a cross ventilation system, it is done by applying two openings on the sides of the building, there are also voids for ventilation.Keywords: architecture, mall, tropical

Abstract. Using the ECMWF/NCEP reanalysis data, satellite observations from AURA MLS and UARS HALOE, and Oceanic Niño Index (ONI) data, the effects of El Niño and La Niña events on the stratospheric water vapor changes are investigated. Overall, El Niño events tend to moisten the lower stratosphere but dry the middle stratosphere. La Niña events are likely to dry the lower stratosphere over a narrow band of tropics (5° S–5° N) but have a moistening effect on the whole stratosphere when averaged over a broader region of tropics between 25° S–25° N. The moistening effect of La Niña events mainly occurs in lower stratosphere in the Southern Hemisphere tropics where a significant 20% increase in the tropical upwelling is caused by La Niña events. El Niño events have a more significant effect on the tropical upwelling in the Northern Hemisphere extratropics than in Southern Hemisphere extratropics. The net effect of ENSO activities on the lower stratospheric water vapor is stronger in the Southern Hemisphere tropics than in the Northern Hemisphere tropics.

Abstract:
This dissertation examines psychoanalysis in a colonial context, tracing its history in early to mid-twentieth century India. A rich, neglected archive of diaries, letters, administrative documents, as well as psychoanalytical and literary writing in Bengali and English, are drawn on to offer an account of the Indian Psychoanalytical Society (est. 1921), and the anthropologists, doctors, army officers and political figures who were in different ways intimately involved with psychoanalysis. Reconstructing these narratives, and by means of a close reading of texts by Freud, I suggest that the understandings of temporality, sexuality and authority in Freudian psychoanalysis resist colonial discourses of progress and civilisation, notably in relation to the category of the 'primitive', thus frustrating attempts to appropriate the theory for colonial endeavours. In this thesis, psychoanalysis is both an object of historical study, and a form of questioning, part of colonial history and a body of writing and theory available for contested readings. I discuss writing by two colonial psychoanalysts, Lt. Colonel Claud Daly, and Owen A.R. Berkeley Hill, which combines an investment in psychoanalysis with commitment to Empire, based on a desire for all-knowing psychic and political mastery. In contrast, the memoirs of renowned psychoanalyst Wilfred Bion, recounting his childhood in India, are read for their more complex psychic register and anti-colonial strain. Records left by dream-collecting colonial administrators in the Naga Hills, and documents relating to the trial and 'insanity plea' of revolutionary nationalist Gopinath Saha, show us the historical operations of psychoanalysis in collective life. In addition, literary writing by the modernist poet H.D., Temsula Ao, Bankimcandra Chatterji, and Rabindranath Tagore, offers another template for examining the issues raised by both the historical and psychoanalytical writing.

Abstract:
Understanding the unequal distribution of life on earth is a fundamental goal of ecology and evolutionary biology. Past efforts to explain large-scale patterns in diversity have tended to focus on two broad classes of explanation, one invoking the importance of abiotic factors (i.e. climate and vegetation) and the other biotic (i.e. competition); but neither has proven entirely adequate. Parasites are a major but poorly understood component of life that may offer some answers. Yet despite widespread theoretical support and some empirical evidence, the role of parasites in explaining patterns in the diversity, distribution, and abundance of species remains largely untested in natural communities. In this thesis I use a mega-diverse elevation gradient of birds as a model system to study the role of avian malaria in explaining these macroecological patterns. In the first data chapter I tested the extent to which patterns of infection across species is predictable. I found that the effects of host ecology and environment were weakly related to infection prevalence and were not consistent across different malaria lineages. Instead, I show that hosts coexisting with many close phylogenetic relatives consistently experience higher infection than evolutionarily distinct host species. In the second chapter I tested if parasite sharing may help explain these observed relationships and show that parasite sharing among host pairs declines with the time since divergence. Spatial contiguity between host pairs was also positively associated with parasite sharing. In the third chapter I tested how infection prevalence varies across species ranges in accordance with expected variation in host abundance. I show that birds are more likely to be infected at the centre of their elevation range, where host abundance is expected to be highest. Intriguingly, I also found that the incidence of host infection is unrelated to the position within the geographic range of the parasite. In the fourth data chapter, I tested whether parasites may regulate diversity by limiting geographic ranges of their hosts through ‘apparent competition’ in which a non-lethal parasite in a primary host, may be lethal in a secondary host. In support of this, I found that more observed bird ranges end at parasite infection zones than would be expected by chance. Taken together, my results suggest that parasites may play a major role in shaping patterns in the distribution and diversity of species, over both ecological and evolutionary scales. This is likely to arise and be maintained by host parasite interactions in which distantly related hosts are less likely to be infected by local parasites than close relatives, thus promoting the build up of diversity locally. On the basis of my analyses, I conclude that across montane elevation gradients in birds, and across diversity gradients more generally, parasites are likely to play a crucial role in the origin and maintenance of high biological diversity.

Abstract:
In tropical areas, the high rainfall induces severe-and pervasive weathering, producing a thick soil cover. The lithologies underneath may b~ recognised using geochemical mapping, which is based on certain elements that have the ability to differentiate between various lithologic units. Elements that are independent of the weathering process are normally selected for this purpose. The chemistry of mobility of base metals is an important factor to take into account when evaluating the mobility and distribution of these elements in a soil profile. Factors such as pH, Eh, organic material, clay minerals, Fe and Mn oxides are normally key aspects to be considered. When iron-rich rocks undergo deep weathering, lateritic profiles are developed. These are widespread in a belt bordering the equatorial zone, including the Brazilian shield, West and East Africa, parts of India and Northern Australia. In these profiles, the high rainfall promotes intense leaching of the different horizons. Where the pre-existing profiles are mostly preserved, the base metals are distributed throughout the profile: in the upper ferruginous horizon, goethite and hematite can adsorb large amounts of Mo, resulting in large dispersion halo. Other base metals such as Cu and Zn are less resistant in these freely-drained profiles and, therefore, they may be partly leached from the profile. In the lower horizons, Cu, ,zn, Ni and Co are retained, hosted in kaolinite and smectite, and thus, a high geochemical contrast will be identified in this horizon at the expense of a decline in the size of the dispersion haloes. The pre-existing profiles can be truncated, with a thin stone line developing at the contact between the lateritic profile and the recent soil. The conditions in these environments favour the retention of most of the pathfinder and target elements in all soil horizons, with the B horizon showing the highest contrast. If the primary rock is rich in AI, a bauxitic profile will be developed. The world distribution of bauxites closely resembles that of laterites. The behaviour of Co and Ni is very similar to that of iron during the bauxitization. Furthermore, the factors that induce residual enrichment of Al with removal of Fe in the soil profile will cause significant depletion of Co and Ni in these profiles. These metals are then concentrated at the base of the profile because of precipitation from downward percolating solutions. Many karst bauxite deposits in Southern Europe are enriched with Ni and Co in the basal horizon. Such horizon is mined as nickel ore in the bauxites of the Lokris region in Greece. Copper and molybdenum are strongly enriched.in bauxitic profiles. Concentration ratios are 8 and 3.2 for Cu and Mo respectively. Molybdenum is closely related to goethite and hematite, and therefore, the high concentration of Mo in a bauxitic profile will be consistent with the horizon where iron is concentrated. Copper concentrates at the base of the iron rich-horizon but also appears enriched in the saprolite together with Co. When sulphide bodies occur, in this environment, deep and penetrative weathering has resulted in considerable near-surface mobilization of iron and silica. The supergene alteration commonly obscures the identity of the primary sulphides at the surface. In this case, geochemical assessment of the resulting gossan has proved to be crucial in mineral exploration. A search in the secondary mineral assemblage, volatile and precious metals may lead to the information on the composition of the primary sulphide assemblage. The conclusion that will be reached is that if the geochemical properties (mobility, affinities with Fe or Mn oxides and/or clay minerals) of each of the base metals are understood, an appropriate sampling (optimum size-depth combination) will then be done. In such cases, a subdued, weak, but significant, geochemical response will be identified in the surface horizon.

Abstract:
AbstractThe study of stable isotopes in tree rings is relatively new, but growing research field in tropical forests. In this chapter, we review 53 studies that measured stable isotopes of C, O and/or N in tree rings of a total of 83 tropical tree species. Tree growth in tropical forests is generally determined by seasonality of precipitation, and not temperature. Consequently, temporal variation in both δ13C and δ18O has often been correlated to precipitation and variability of the El Niño Southern Oscillation (ENSO), which can affect weather systems throughout the tropics and subtropics. Currently, stable isotopes research in the tropics has mainly focused on (i) quantifying the effects of rising atmospheric CO2 concentration and climate change on tree physiology, (ii) identifying the drivers of growth variability and reconstruction of past climate, and (iii) the identification of annual rings in wood lacking anatomically distinct growth boundaries. In addition, some initial studies used tree-ring δ15N as a tool to assess anthropogenic change of the nitrogen cycle in tropical forests. Although stable isotope analyses in the tropics still faces methodological and interpretation issues, it is becoming an important tool for understanding the functioning of tropical forests and their resilience to global change.

Abstract:
AbstractThe study of stable isotopes in tree rings is relatively new, but growing research field in tropical forests. In this chapter, we review 53 studies that measured stable isotopes of C, O and/or N in tree rings of a total of 83 tropical tree species. Tree growth in tropical forests is generally determined by seasonality of precipitation, and not temperature. Consequently, temporal variation in both δ13C and δ18O has often been correlated to precipitation and variability of the El Niño Southern Oscillation (ENSO), which can affect weather systems throughout the tropics and subtropics. Currently, stable isotopes research in the tropics has mainly focused on (i) quantifying the effects of rising atmospheric CO2 concentration and climate change on tree physiology, (ii) identifying the drivers of growth variability and reconstruction of past climate, and (iii) the identification of annual rings in wood lacking anatomically distinct growth boundaries. In addition, some initial studies used tree-ring δ15N as a tool to assess anthropogenic change of the nitrogen cycle in tropical forests. Although stable isotope analyses in the tropics still faces methodological and interpretation issues, it is becoming an important tool for understanding the functioning of tropical forests and their resilience to global change.

Abstract:
In early 1996, our two organizations measured infrared atmospheric radiances with two independent Fourier Transform InfraRed (FTIR) spectro-radiometers on the NOAA R/V Discoverer in the tropical Pacific. Our objective was to make highly accurate measurements that would be useful for improving radiative transfer models and for establishing FTIR technology as a practical tool for measuring atmospheric radiation in the tropics. However, the usual problem with such an approach is that there is no easy way to assess the accuracy of the resulting data. Therefore, comparing measurements from the two FTIR systems is useful.

Abstract:
This study is focused on vernacular features from eclectic architecture from the Colombian tropics, particularly on the San Jeronimo de Monteria Cathedral, one of the most important architectural symbols from this Colombian city. During the 19th and early 20th centuries, architecture in Europe and America was characterized by a resumption of historical styles, generally called ‘revivals’, and the blend of these, ‘eclecticism’. Montería was no stranger to this situation, also assisted by national and international migrations into the territory and the adaptation of local vernacular techniques. This cathedral is explored as an example where elements from vernacular tradition are recognized, which guaranteed the operation of foreign models, especially in the bioclimatic functioning of this tropical region.
