Climate change is increasing the frequency and severity of short-term (~1 y) drought events—the most common duration drought—globally. Yet impact this intensification on ecosystem functioning remains poorly resolved. This due in part to widely disparate approaches ecologists have employed study drought, variation studied, differences among ecosystems vegetation, edaphic climatic attributes that can mediate impacts. To overcome these problems better identify factors modulate responses, we...
This study evaluated symptoms, risk, and protective factors of adolescents from six Israeli schools exposed to continuous terrorism. All children in the grades selected at each school (7, 9, 11) were administered anonymous assessment materials measuring posttraumatic, grief, dissociative as well traumatic exposure, personal resilience, family factors. A high number risk increased likelihood negative symptoms. Perceived resilience served a factor against symptom development, perhaps enforced...
Abstract Questions What are the effects of extreme drought on above‐ground and below‐ground net primary production (ANPP BNPP, respectively) an annual plant community in a Mediterranean shrubland? How do communities shrublands respond to drought, terms changes their species composition, richness, diversity? Location A shrubland Judean Hills, Israel. Method Rainout shelters were used simulate 66% reduction rainfall, preceded by baseline year when no treatments applied. Above‐ground (i.e.,...
Summary Plant–microbe mutualisms, such as the legume‐rhizobium symbiosis, are influenced by geographical distributions of both partners. However, limitations on native range legumes, resulting from absence a compatible mutualist, have rarely been explored. We used combination large‐scale field survey and controlled experiments to determine realized niche Calicotome villosa , an abundant widespread legume shrub. Soil type was major factor affecting distribution abundance C. . In addition, we...
Abstract Legumes in dryland ecosystems face the challenge of maintaining energetically costly symbiosis with N 2 ‐fixing rhizobia, a water‐ and nutrient‐limited environment. Controlled experiments showed strong reduction symbiotic fixation response to elevated levels nitrogen availability, but this regulation was not found field settings. Here, we ask whether occurs what are possible consequences for soil nitrogen. We measured plant investment root nodules rates bacterial activity, seedlings...
This study examines the impact of structured sensitivity training on teachers' perception their pupils. Thirty-four female teachers were exposed to one four programs: Group 1, main experimental group, took part in which everyday situations school analyzed. Case-study protocols from Bar-Ilan Picture Test for Children, a semiprojective interview, used as didactic tool 2 participated unstructured focused group processes according classical model T-training. Groups 3 and 4 comparison groups....
To determine the perinatal outcome of monochorionic diamniotic (MCDA) twin pregnancies with amniotic fluid discordance. Prospective cohort study 34 MCDA discordance without meeting criteria for twin–twin transfusion syndrome (TTTS) or selective intrauterine growth restriction (sIUGR). All were followed by ultrasonographic scans every 2 weeks biometry and Doppler evaluation. Perinatal outcomes measures compared to a control group consisted 101 uncomplicated pregnancies. Major neonatal...
