Masticophis mentovarius (Duméril, Bibron & Duméril, 1854) occurs at low and moderate elevations in Lowland Dry Forest and Premontane Moist Forest. This species is known in Costa Rica mainly from the dry lowlands of the northwest. Here we report the presence of M. mentovarius at the Tropical Cloud Forest of Monteverde, Costa Rica, at 1275 m a.s.l. The new records provide information on the true limits of the distribution of species and may represent expansion of the species’ range due to environmental changes caused by global climate change.

Environmental Response

Average global temperatures are predicted to rise over the next century and changes in precipitation, humidity, and drought frequency will likely accompany this global warming. Understanding associated changes in continental precipitation and temperature patterns in response to global change is an important component of long-range environmental planning. For example, agricultural management plans that account for decreased precipitation over time will be less susceptible to the effects of drought through implementation of water conservation techniques.A detailed understanding of environmental response to past climate change is key to understanding environmental changes associated with global climate change. To this end, diatoms are sensitive to a variety of limnologic parameters, including nutrient concentration, light availability, and the ionic concentration and composition of the waters that they live in (e.g. salinity). Diatoms from numerous environments have been used to reconstruct paleosalinity levels, which in turn have been used as a proxy records for regional and local paleoprecipitation. Long-term records of salinity or paleoprecipitation are valuable in reconstructing Quaternary paleoclimate, and are important in terms of developing mitigation strategies for future global climate change. High-resolution paleoclimate records are also important in groundtruthing global climate simulations, especially in regions where the consequences of global warming may be severe.

Northeastern Region

During the 20th century, several catastrophic pluvial and fluvial floods took place over the northeastern region of Argentina. These disastrous floods caused great damage worth hundreds of millions of US dollars. The rehabilitation programme was supported by regional economies. The idea of this paper is to point out the risks of greater floods as a consequence of the global climatic change. The experiences obtained from the palaeogeomorphological research, historical data over the regional rivers, and the climatic and environmental changes are taken into account in this research. The record of the geomorphological study of the region strongly suggests that in past epochs, different wet and dry periods occurred with the global climate change, especially in the Quaternary Period. It is possible to infer that the region is very sensitive to these changes and anthropogenic action. On the other hand, environmental and climatic conditions show a tendency of tropicalising the area. In this case, consequences are unpredictable if the processes are evolving rapidly. It is possible to observe that after the 1960's, the characteristics of the fluvial courses are changing. The changes are in the direction of the maximum and minimum amplitudes with the same mean values. Besides, the frequency of large floods has increased from the 1960’s. The Parana River, the largest fluvial course of the region, serves as a model for the propositions mentioned above. This is because we have historical records from 1748 on high flood levels and hydrometrical measurements from 1900. The northeastern region is a very vast and flat plain with an inefficient drainage system. This physical framework induces pluvial flooding, which covers millions of hectares. True catastrophes develop when pluvial and fluvial floods coincide. The record of overflows has a recurrence period of less than 50 years. This strongly suggests a very high risk. In the 21st century, it is very probable that flooding phenomena greater than known will occur. But no mitigation measures are planned to face them.

Projected Changes

The projected behavioral impacts of global climate change emanate from environmental changes including temperature elevation, extreme weather events, and rising air pollution. Negative affect, interpersonal and intergroup conflict, and possibly psychological distress increase with rising temperature. Droughts, floods, and severe storms diminish quality of life, elevate stress, produce psychological distress, and may elevate interpersonal and intergroup conflict. Recreational opportunities are compromised by extreme weather, and children may suffer delayed cognitive development. Elevated pollutants concern citizens and may accentuate psychological distress. Outdoor recreational activity is curtailed by ambient pollutants. Limitations and issues in need of further investigation include the following: lack of data on direct experience with climate change rather than indirect assessments related to projected changes; poor spatial resolution in environmental exposures and behavioral assessments; few rigorous quasi-experimental studies; overreliance on self-reports of behavioral outcomes; little consideration of moderator effects; and scant investigation of underlying psychosocial processes to explain projected behavioral impacts.
