The Andean bear (Tremarctos ornatus) population density and relative abundance within the Chingaza Massif were assessed between September 2015 and May 2016. One hundred seventeen (117) camera traps were installed at 9 grids: 13 cameras per grid, each camera separated 750 m from the other; the sampling effort was 17,057 days-trap. Two thousand seven hundred eighty-four (2,784) native fauna records were obtained, 1,456 corresponding to mammals, 183 records for Andean bear specimens, 158 of them independent bear records (at least one hour between records), and 106 effective-independent bear records (also permitting individual recognition). Fifty-seven (57) Andean bear individuals were identified according to key external morphological features. Sixteen (16) adults were recaptured (12 males and 4 females), with a maximum mean distance of 27.22 km. Bears population density was 2.9 bears per 100 km². Based on this density and the buffer area of the sampling grids, we estimated an overall number of 122 bears in 4,215.15 km². The estimated density is the first for the species in Colombia and the lowest regarding previous reports from other countries. Thus, it is necessary to better understand how integral habitat quality and the anthropic impacts on habitat quality, availability, and connectivity may affect the Andean bear population densities in Colombia, as a useful tool for assessing populations` state and focus future conservation actions.

The aim of this research is to elaborate of the impacts on the use of the effluent of the water treatment plant Pinedo in the North of Albufera Natural Park in Valencia, Spain. Interviews and observations were conducted, which together created an Impact Assessment. To be able to see the influence of effluent on the water quality, an observation point in the north was compared to another observation point in the south. Besides that, a boat trip was made to observe the water quality on the lake. The result shows that eutrophication occurs as a cosequence of the wastewater from water treatment. Farmers have no choice and are happy to have a constant source. Fishermen have experienced a disastrous change in the seventies, but now see an improvement of the water quality. Environmentalists are most negative about the effluent inflow. The government understands the concerns and wants a higher quality of the effluent, but they do not have means to improve it. Water treatment plant Pinedo recognizes the corncerns either; however, the water quality already meets the requirements. Forecasting the future, everybody is slightly positive. The improvement of the quality of the effluent is a good thing and should carry on.

First Time

Colombia is one of the megadiverse countries in the world, but paradoxically it is one of the less explored. The recent red list assessments show the country has the highest number of endangered species in the Neotropical region. Nevertheless, the sampling effort is low especially in protected areas, which probably can harbor some of the rare species included in the red list. As a result of recent surveys in six protected areas of Colombia, we report twelve new records and describe Cora verapax sp. nov., a rare species, collected after more than 300 days of field surveys at the National Natural Park Tatamá. In addition, we compiled and mapped published Odonata records from 2001 until now for Colombian protected areas (136 spp.). Among the new records, some species were formerly known as endemics from Panama and Ecuador, and five species are reported for the first time inside protected areas, showing the importance of surveys in these special territories and bringing new data for conservation actions, as red list assessment or future management plans.
