L'experiència del projecte europeu GAP Work, de formació de professionals que treballen amb joves en el camp de la prevenció de les violències de gènere, ens permet reflexionar sobre alguns elements a tenir en compte per formar professionals en el marc d'una Investigació-Acció que contempli propostes feministes a l'aula i en els equips de treball. En aquest article mostrarem tensions i conflictes en el disseny de les formacions i reflexionarem sobre les dificultats de portar a la pràctica un paradigma ampli de les violències de gènere amb pedagogies feministes. Abans d'arribar a les conclusions, ens aproximarem a un projecte de continuïtat del GAPWork en el que algunes participants dels nostres cursos han seguit el seu procés de desenvolupament d'estratègies de prevenció de violències de gènere amb joves. Finalment resumirem alguns dels aprenentatges de la nostra intervenció per estimular la continuació del debat.

Ruminants are born with an undeveloped physical, metabolic, and microbial rumen. Rumen development is limited under artificial rearing systems when newborn animals are separated from the dam, fed on milk replacer, and weaned at an early age. This study aims to evaluate the effects of early-life inoculation of young ruminants with rumen fluid from adult animals. Eighty newborn goat kids were randomly allocated to 1 of 4 experimental treatments and inoculated daily from d 1 to wk 11 with autoclaved rumen fluid (AUT), fresh rumen fluid obtained from adult goats fed either a forage diet (RFF) or concentrate-rich diet (RFC), or absence of inoculation (CTL). Goat kids were artificially reared with ad libitum access to milk replacer, starter concentrate, and forage hay. Blood was sampled weekly and rumen microbial fermentation was monitored at 5 (preweaning), 7 (weaning), and 9 wk of age (postweaning). Results indicated that inoculation with fresh rumen fluid accelerated the rumen microbial and fermentative development before weaning. As a result, RFC and RFF animals had higher solid feed intake (+73%), rumen concentrations of ammonia-N (+26%), total volatile fatty acids (+46%), butyrate (+50%), and plasma β-hydroxybutyrate (+48%), and lower milk intake (−6%) than CTL and AUT animals at wk 5. Inoculation with fresh inoculum also promoted early rumen colonization by a complex and abundant protozoal community, whereas CTL animals remained protozoa free. Although all kids experienced moderate growth retardation during 1 wk after weaning, inoculation with fresh rumen fluid favored the weaning process, leading to 2.2 times higher weight gain than CTL and AUT animals during wk 8. Some of these advantages were retained during the postweaning period and RFF and RFC animals showed higher forage intake (up to +44%) than CTL and AUT animals with no detrimental effects on feed digestibility or stress levels. The superior microbial load of RFC compared with RFF inoculum tended to provide further improvements in terms of forage intake, plasma β-hydroxybutyrate, and rumen protozoa, whereas AUT inoculation provided minor (if any) advantages with respect to CTL animals. Although no differences were noted on animal growth, this study suggests that early life inoculation of goat kids with rumen microbiota can represent an effective strategy to accelerate the rumen development, facilitating a smooth transition from milk to solid feed and to the potential implementation of early weaning strategies. ; This study was funded by the Spanish government through the project AGL2017-86938-R and the Training Program for Academics grant, Madrid, Spain (FPU16/01981).

Estimates of extinction risk for Amazonian plant and animal species are rare and not often incorporated into land-use policy and conservation planning. We overlay spatial distribution models with historical and projected deforestation to show that at least 36% and up to 57% of all Amazonian tree species are likely to qualify as globally threatened under International Union for Conservation of Nature (IUCN) Red List criteria. If confirmed, these results would increase the number of threatened plant species on Earth by 22%. We show that the trends observed in Amazonia apply to trees throughout the tropics, and we predict that most of the world's >40,000 tropical tree species now qualify as globally threatened. A gap analysis suggests that existing Amazonian protected areas and indigenous territories will protect viable populations of most threatened species if these areas suffer no further degradation, highlighting the key roles that protected areas, indigenous peoples, and improved governance can play in preventing large-scale extinctions in the tropics in this century. ; Alberta Mennega Stichting ; ALCOA Suriname ; Amazon Conservation Association ; Banco de la República ; CELOS Suriname ; CAPES (PNPG) ; Conselho Nacional de Desenvovimento Científico e Tecnológico of Brazil (CNPq) Projects CENBAM, PELD (558069/2009-6), PRONEX-FAPEAM (1600/2006), Áreas Úmidas, MAUA; PELD (403792/2012-6), PPBio, PVE 004/2012, Universal (479599/2008-4), and Universal 307807- 2009-6 ; FAPEAM projects DCR/2006, Hidroveg with FAPESP, and PRONEX with CNPq ; FAPESP ; Colciencias ; CONICIT ; Duke University ; Ecopetrol ; FEPIM 044/2003 ; The Field Museum ; Conservation International/DC (TEAM/Instituto Nacional de Pesquisas da Amazônia Manaus ; Gordon and Betty Moore Foundation ; Guyana Forestry Commission ; Investissement d'Avenir grant of the French ANR (CEBA: ANR-10-LABX-0025 ; IVIC ; Margaret Mee Amazon Trust ; Miquel fonds ; MCTI–Museu Paraense Emílio Goeldi–Proc. 407232/2013-3–PVE-MEC/MCTI/CAPES/CNPq; National Geographic Society (7754-04 and 8047-06 to P.M.J.; 6679-99, 7435-03, and 8481-08 to T.W.H.); NSF-0726797 to K.R.Y ; NSF Dissertation Improvement ; Netherlands Foundation for the Advancement of Tropical Research WOTRO (grants WB85-335 and W84-581) ; Primate Conservation Inc. ; Programme Ecosystèmes Tropicaux (French Ministry of Ecology and Sustainable Development) ; Shell Prospecting and Development Peru ; Smithsonian Institution's Biological Diversity of the Guiana Shield Program ; Stichting het van Eeden-fonds ; The Body Shop ; The Ministry of the Environment of Ecuador ; TROBIT ; Tropenbos International ; U.S. National Science Foundation (NSF-0743457 and NSF-0101775 to P.M.J.; NSF-0918591 to T.W.H.) ; USAID ; Variety Woods Guyana ; Wenner-Gren Foundation ; WWF-Brazi ; WWF-Guianas ; XIIéme Contrat de Plan Etat Région-Guyane (French Government and European Union) ; European Union ; UK Natural Environment Research Counci ; European Research Council ; Royal Society Wolfson Research Merit Award
