the aim of this study is to investigate the tree species' diversity in a region with no management planning and introduce the calculated indices as the norm for sustainability assessment. dbh of all tree individuals, and their stories were recorded in the inventory grid (75 m × 100 m) sample plots. subsequently, richness, evenness (simpson, smith & wilson) and heterogeneity (simpson, shann...
OBJECTIVE: To share knowledge and information about the peculiarities of the Freeman-Sheldon syndrome, especially concerning the high risk of recurrence of its recessive type in siblings, and to stress the importance of genetic counseling for families after the birth of an affected child. DESCRIPTION: The authors describe and comment two pediatric cases of the Freeman-Sheldon syndrome in siblin...
It is generally assumed that functional richness, diversity and evenness are complementary and, taken together, describe different facets of the distribution species their abundances in space. However, although these three primary components community structure commonly accepted by most ecologists, measures usually fail to properly capture regularity In this paper we will use an underexplored d...
Diet guidelines recommend increasing dietary diversity. Yet, metrics for dietary diversity have neither been well-defined nor evaluated for impact on metabolic health. Also, whether diversity has effects independent of diet quality is unknown. We characterized and evaluated associations of diet diversity and quality with abdominal obesity and type II diabetes (T2D) in the Multi-Ethnic Study of ...
Abstract Aim Biodiversity loss results in reduced ecosystem functioning. However, the relationship between biodiversity and functioning (the BEF relationship) overexploited ecosystems remains controversial largely because of lack validation nature. Therefore, this study, through four seasonal trawl surveys demersal fish assemblages off shelf sea Shandong Province, China, we explored relationshi...
A 5-month-old male infant presented with weak cry, decreased body movements, tightness of whole body since birth, and one episode of generalized seizure on day 4 of life. He was born at term by elective caesarian section performed for breech presentation. The child had failure to thrive, contractures at elbow and knee joints, hypertonia, microcephaly, small mouth, retrognathia, and camptodactyl...
The Hemiptere Order of the Family Reduviidae has an important role in ecosystem, namely as a natural enemy (predator) insects, hemiptera group itself and other arthropods. This study aims to determine predation abundance enemies order Hemiptera family reduviidae on oil palm plantations. research was carried out area productive plantation village Karapyak, Cintamekar Serangpanjang, Subang, Jawa ...
To gain insight into the ecological processes driving community reassembly in disturbed ecosystems, we assessed the phylogenetic dispersion of earlyand late-successional tree species occurring in lowland forests of northeastern Costa Rica. Early-successional species were more closely related than expected by chance, whereas late-successional species tended to be less closely related than expect...
