... Agent selection for prickly acacia has been largely dictated by logistics and host specificity. Given that detailed ecological information is available on this species in Australia, we propose that it is possible to select agents based on agent efficacy and desired impact on prickly acacia demography. We propose to use the 'plant genotype' and 'climatic' similarities as filters to identify areas f ...
... Cognitive abilities evolve by natural selection to help an organism cope with problems encountered in the organism’s typical environment. In acacia ants, coevolution with the acacia tree led workers to forage exclusively on the host plant (“in-nest” foraging), instead of the central-place foraging typical for most social insects. To test whether foraging ecology altered the orientation skills of a ...

Thus, the aim of this work was to evaluate the general phenolic parameters, aroma composition and sensory profile of rosé wines during a short maturation (20 aging days) in contact with wood chips from oak, acacia and cherry. In addition, the different wo ...
... BACKGROUND AND AIMS: In anticipation of global climate change, the question of whether shifts in plant community composition (beta-diversity) are predictable from environmental variation is receiving considerable interest. Species strongly associated with local soil environments may be more vulnerable to climate change than species with a broad tolerance of soil conditions. Here we investigate rel ...

The objective of the present study was to determine the acaricidal activity of arecoline hydrobromide against cattle tick Rhipicephalus microplus infesting calves. in vivo efficacy of arecoline emulsified with polysorbate-80 (2%) was evaluated using ear bag method with the effective dose of 12.5 mg/mL applied on ear pinna of calves infested with ticks. Control group received polysorbate-80 (2%) af ...
... A perfect wound covering should prevent dryness of the wound and provide a favourable moist milieu at the wound interface allowing gas access but act as a barrier to the dirt and microorganisms. It is imperative to ensure early restoration of wound without scar formation at the site. Topical application of antiseptic preparation is the best for wound treatment because of its direct action. Zinc ox ...
... Transpiration per unit leaf area of Acacia farnesiana (L.) Willd. plants grown at a CO2 concentration ([CO2]) of 385 micromol mol(-1) was about twice that of plants grown at 980 micromol mol(-1). However, when plants grown for more than a year at 980 micromol mol(-1) were exposed to 380 micromol mol(-1) for 9 days, they transpired at half the rate of those that had been grown at 380 micromol mol(- ...
... • Premise of the study: Few studies have investigated the effects of substrates on the accumulation and precipitation of magnesium, calcium, and sulfur in plants. Acacia stipuligera and A. robeorum growing in their natural habitats with different substrates show different accumulation and precipitation patterns of these elements. Here, we compared the accumulation and precipitation of magnesium, c ...
Acacia; leaves; nonprotein amino acids; quantitative analysis; ion exchange chromatography; chemical constituents of plants; genotype; high performance liquid chromatography
Abstract:
... Acacia angustissima has potential in agroforestry systems for forage production in tropical environments. However, feeding trials indicate that the leaves are potentially toxic. Signs of toxicity in sheep are similar to those presented by sheep fed flatpea (Lathyrus sylvestris) hay which contains a high concentration of the non-protein amino acid 2,4-diaminobutanoic acid (DABA). Cation exchange ch ...
... AIM: Macroevolutionary analysis is increasingly being used to study biodiversity responses to climate change, for example by using phylogenetic node ages to infer periods of diversification, or phylogenetic reconstruction of traits to infer adaptation to particular stresses. Here we apply a recently developed macroevolutionary method to investigate the responses of a diverse plant genus, Acacia, t ...

Abstract:
... The effects of addition of carbonated residue mud (RMC) or seawater neutralized residue mud (RMS), at two rates, in the presence or absence of added green waste compost, on the chemical, physical and microbial properties of gypsum-treated bauxite residue sand were studied in a laboratory incubation study. The growth of two species commonly used in revegetation of residue sand (Lolium rigidum and A ...
... The effect of the time of wood chip addition on phenolic content, color parameters and volatile composition of a red wine made by a native Greek variety (Agiorgitiko) was evaluated. For this purpose, chips from American, French, Slavonia oak and Acacia were added in the wine during and after fermentation. Various chemical parameters of wines were studied after one, two and three months of contact ...

Abstract:
... Floral resources, such as carbohydrate-rich nectar or pollen, can bolster fitness and raise reproductive output of adult lepidopterans. Here, we used laboratory experiments to assess how those plant-derived foods impact adult fecundity, reproductive physiology and flight performance of an invasive strain of the fall armyworm, Spodoptera frugiperda (FAW; Lepidoptera: Noctuidae) in China. More speci ...
... Biological control of invasive Australian acacias will benefit from recent advances in resolving the phylogenetic relationships of Acacia s.l. and Acacia s.s. (“Australian acacias”) within the subfamily Mimosoideae. Some of the phytophage taxa associated with Acacia s.s. display fidelity to a derived clade within the genus. This derived clade contains most of the Acacia s.s. species that have beco ...
