Regenerating mahogany (Swietenia macrophylla King) on clearing in Mexico's Maya forest: the effects of clearing method and cleaning on seedling survival and growth por Snook, Laura K., Negreros-Castillo, P.

“…To mimic catastropic disturbances which have favored the establishment of natural stands rich in mahogany (Swietenia macrophylla), two 5000 square meter clearings were established in each locations using each of three treatments: complete felling; slash and burn; machine-clearing with uprooted all prior vegetation. …”

Mapping genetic diversity of Cherimoya (Annona cherimola Mill.): application of spatial analysis for conservation and use of plant genetic resources por Zonneveld, M. van, Scheldeman, Xavier, Escribano, P., Viruel, M.A., Damme, Patrick van, García, W., Tapia, C., Romero, J., Siguenas, M., Hormaza, J.I.

“…We present spatial analyses to (1) improve the understanding of spatial distribution of genetic diversity of cherimoya natural stands and cultivated trees in Ecuador, Bolivia and Peru based on microsatellite molecular markers (SSRs); and (2) formulate optimal conservation strategies by revealing priority areas for in situ conservation, and identifying existing diversity gaps in ex situ collections. …”

Climate change and forest genetic resources - state of knowledge, risks, and opportunities por Loo J, Fady, B., Dawson, I., Vinceti, B., Baldinelli, G.

“…This paper considers forest genetic resources in the different settings where people depend on products and services from trees for a wide variety of purposes, including naturally regenerating forests, commercial plantations, and trees on farms (including planted trees and wild remnants left standing for various functions). The expected impacts of climate change and hence strategies for responding to it differ among these environments. …”

Assessment of fungal toxins in the dairy value chain and potential risk to human health in Kenya por Kirino, Y., Lindahl, Johanna F., Makita, K., Grace, Delia

“…Overview of raw milk distribution system in Dagoretti revealed that there were 5 business types: kiosks (71%), dairy shops (21%), street or door-to-door vendors (3%) grocery stands (1%) and unidentified (4%), and their milk is mainly sourced directly from dairy farms (59%) or from intermediate distributors (35 %). …”

Modeling and participatory farmer-led approaches to food security in a changing world: A case study from Malawi por Snapp, Sieglinde S., Kerr, R.B., Smith, A., Ollenburger, M.H., Mhango, W., Shumba, L., Gondwe, T.N.P., Kanyama-Phiri, G.Y.

“…Using historical rainfall records, simulated yield (Agricultural Production Systems Simulator, APSIM) from maize and pigeon pea-maize intercrop and rotation systems was compared to food requirements for 12 households selected to represent a range of wealth status.Wefound that pigeon pea-maize intercrops were highly likely to produce sufficient calories for smallholder households across variable rainfall patterns, from 73 to 100% of the years simulated, for 10 out of 12 case study households. This stands in contrast to monoculturemaize,where sufficient calories were consistently produced for only half of the case study households. …”

Second-tier community forestry organisations and equitable resource management in the Maya Biosphere Reserve, Guatemala por Millner, N., Penagaricano, I., Fernández, M., Snook, Laura K.

“…However, the role of intermediary organisations in negotiating such rights and rules is of central analytical importance - especially in contexts where pre-existing power and gender relationships influence who makes which decisions and how, and where long-standing conflicts over access to land constantly over-determine the possibilities for upscaling successful projects. …”

Improving the use of crop models for risk assessment and climate change adaptation por Challinor, Andrew J., Müller, Christoph, Asseng, Senthold, Deva, Chetan, Nicklin, Kathryn Jane, Wallach, Daniel, Vanuytrecht, Eline, Whitfield, Stephen, Ramírez Villegas, Julián Armando, Köhler, Ann-Kristin

“…The analysis highlights the limitations of focussing only on projections of future impacts and adaptation options using pre-determined time slices. Whilst this long-standing approach may remain an essential component of risk assessments, we identify three further key components: 1. …”

A cost-efficient method to assess carbon stocks in tropical peat soil por Warren, M.W., Kauffman, J.B., Murdiyarso, Daniel, Anshari, G, Hergoualc'h, Kristell, Kurnianto, S., Purbopuspito, J., Gusmayanti, E, Afifudin, M, Rahajoe, J, Alhamd, L, Limin, S, Iswandi, A.

“…Predicted carbon densities and stocks are compared with those obtained from direct carbon analysis for ten peat swamp forest stands in three national parks of Indonesia. Analysis of soil carbon density and bulk density from the literature indicated a strong linear relationship (Cd = Bd × 495.14 + 5.41, R2 = 0.93, n = 151) for soils with organic C content > 40%. …”

A systematic review of non-productivity-related animal-based indicators of heat stress resilience in dairy cattle por Galan, Elena, Llonch, Pol, Villagrá, Arantxa, Levit, Harel, Pinto, Severino, del Prado, Agustin

“…The most common physiological animal-based indicators are rectal temperature, respiration rate and dry matter intake, while the most common behavioural indicators are time spent lying, standing and feeding. Conclusion Although body temperature and respiration rate are the animal-based indicators most frequently used to assess heat stress in dairy cattle, when choosing an animal-based indicator for detecting heat stress using scientific literature to establish thresholds, characteristics that influence the scale of the response and the definition of heat stress must be taken into account, e.g. breed, lactation stage, milk yield, system type, climate region, bedding type, diet and cooling management strategies.…”

The effect of different disturbance treatments on tree production, competition, shortroot presence and ectomycorrhizal colonisation in Ericaceae-feathermoss boreal forests por Eriksson, Björn

“…In many northern boreal stands, forest floor vegetation constitutes a considerable part of total biomass and production, and consequently is likely to be critical in determining tree seedling growth. …”

Bedömning av vattenkvalité i Sverige och Tyskland – en jämförande studie i teori och praktik por Neumann, Dörthe

“…The German method always classifies the watercourses with a lower classification class that stands for a better water quality. The results probably reflect the difference between the methods to set classification scales and class limits used in every country. …”
