We report the southernmost record of Cruziohyla craspedopus in Ecuador. An adult female was collected in the province of Zamora Chinchipe in southern Ecuador in the Cordillera del Condor. This record increases the previously reported altitudinal range for the species by 468 m and extends the distribution by 105 km to the south. © 2015 Check List and Authors.

The problems of delimitation of species of Prosopis originate from the few morphological discontinuities which exist among some of them; some, however, originated as a result of wide distribution of germplasm without proper knowledge of the species, in particular, much material catalogued as P. juliflora, but being of other species, was distributed for reforestation projects worldwide. This work tests the morphological results obtained for P. pallida and P. limensis of the Peruvian-Ecuadorian coast and for P. juliflora of the Caribbean Basin of Colombia and Venezuela utilizing a study of AFLPs and a study of the morphology of plantlets developed in a conventional garden study. The phenogram obtained for the AFLPs demonstrates each of the three species to be a well differentiated cluster and the molecular variance between them is significantly greater than the variance within each species. Study of the plantlets also indicates statistically significant differences for four morphological characters between P. juliflora and the other two species (P. pallida and P. limensis). These results, in addition to the morphological differentiation evident between adult plants of P. pallida and P. limensis and the clear separation of these two species from P. juliflora, corroborate the genetic identity of the three taxa analyzed. © 2011 Springer-Verlag.

Trees - Structure and Function | Year: 2016
Key message: Striking hydro-climatic differences of 2 years (wet; dry) dramatically control the increment pattern ofL. huasangoin varying extent, even causing a “growth collapse” during the La Niña drought 2010/2011.Abstract: We present the first multi-year long time series of local climate data in the seasonally dry tropical forest in Southern Ecuador and related growth dynamics of Loxopterygium huasango, a deciduous tree species. Local climate was investigated by installing an automatically weather station in 2007 and the daily tree growth variability was measured with high-resolution point dendrometers. The climatic impact on growth behaviour was evaluated. Hydro-climatic variables, like precipitation and relative humidity, were the most important factors for controlling tree growth. Changes in rainwater input affected radial increment rates and daily amplitudes of stem diameter variations within the study period from 2009 to 2013. El Niño Southern Oscillation (ENSO) related variations of tropical Pacific Ocean sea surface temperatures influenced the trees’ increment rates. Average radial increments showed high inter-annual (up to 7.89 mm) and inter-individual (up to 3.88 mm) variations. Daily amplitudes of stem diameter variations differed strongly between the two extreme years 2009 (wet) and 2011 (dry). Contrary to 2009, the La Niña drought in 2011 caused a rapid reduction of the daily amplitudes, indicating a total cessation (‘growth collapse’) of stem increment under ENSO-related drought conditions and demonstrating the high impact of climatic extreme events on carbon sequestration of the dry tropical forest ecosystem. © 2016 Springer-Verlag Berlin Heidelberg

Ecosystem Services | Year: 2014
Payment for ecosystem services programs are being implemented in a wide variety of settings, but whether and in what contexts such programs present 'win-win' scenarios that simultaneously improve human well-being and achieve conservation goals remains poorly understood. Based on semi-structured interviews with early program participants enrolling either collectively- or individually-held land, we evaluated whether and how SocioPáramo, a national-scale PES program targeting Ecuadorian Andean grasslands (páramos), has the potential to contribute to local livelihoods (financial, natural, social, human, and physical capital) and sustainable resource management. Low conservation opportunity costs associated with pre-existing constraints on land use and the existence of alternative livelihood options appeared to facilitate largely positive financial capital outcomes, although we found reduced financial capital among some smaller and medium-sized landholders who were required to eliminate burning and grazing. We found the greatest potential for improved social, financial, and natural capital among well-organized community participants enrolling collective land, while greater attention to building capacity of individual smaller landholders could improve outcomes for those participants. These results help fill a gap in knowledge by drawing on empirical data to demonstrate how divergent outcomes have begun to emerge among different groups of SocioPáramo participants, providing lessons for PES program design. © 2014 Elsevier B.V.
