Few reports have been published on cytogenetics in crickets of the subfamily Nemobiinae. Within the Neotropical region the karyotypes of only two species are known, both of them belonging to the genus Phoremia. In the present paper, chromosomes of a third Neotropical species, Zucchiella atlantica Mello 1990 (Orthoptera: Trigonidiidae), have been studied and a cytological review of other species...

In order to evaluate the inter-specific hybrid of P. atlantica × P. vera cv. ‘Badami Zarand’ to salinity stress, an experiment was conducted as a factorial based in a completely randomized design with 0, 60, 120 mM salinity levels of NaCl2, CaCl2 and MgCl2 (3:2:1) on two rootstocks ‘Qhazvini’ and ‘Badami Zarand’ and an inter- specific hybrid of P. atlantica × P. vera cv. ‘Badami Zarand’. Minera...

The Atlas cedar, Cedrus atlantica is a resinous species of Pinaceae originated from North Africa and well known for its noble timber. This work was conducted to assess the natural durability of its wood, to study the chemical composition of essential oil extracted from its sawdust wood and to test the bioactivity of this essential oil against four wood decaying fungi: Gloeophyllum trabeum, Olig...

We applied the concept of source-sink dynamics to investigate a recent (1999-2013) increase in the occurrence of the siphonophore Muggiaea atlantica in Scottish coastal waters. Our aim was to determine whether this change represented the establishment of resident populations (i.e. "sources"), or transient populations reliant on immigration (i.e. "sinks"). First, we show that local production wa...

Maritime pine bark (Pinus pinaster Aiton subsp. atlantica) is rich in polyphenols with known bioactive properties which are beneficial for human health. However, biological activities of extracts depend on the type extracted and characteristics these extractives several factors such as solvents used. The influence extraction solvent composition consequently has been poorly described. Thus, this...

The aim of this work is to determine the effect extraction method on yield, chemical composition, and antifungal activity cedarwood essential oils (EOs) from sawdust Moroccan Cedrus atlantica (C. atlantica). EOs were extracted by different methods: hydrodistillation, soxhlet, maceration, ultrasound. composition was determined using gas chromatography mass spectrometry (GC-MS) analysis. yields 5...

Development of minimally invasive techniques to collect blood in free-living birds is desirable for both ethical and conservation reasons. We describe a new, simple technique for collecting blood samples from waterfowl eggs that involves recovering blood from a small hemorrhage after puncturing the shell of eggs showing the first signs of hatching. This technique allowed us to obtain a large nu...

This work is a part of the Taiwan Cooperative Oceanic Fisheries Investigation, the first large scale hydrographic and plankton survey around Taiwan (21-26°N, 119-123°E). The present study examined the influence of hydrodynamic and biological variables driven by monsoon system on the siphonophore assemblages through an annual cycle in 2004. Calycophorans, namely Chelophyes appendiculata, Diphyes...

Early life stages of cephalopods are somewhat complex due to the life 15 history strategy or species specificity of generalized ontogenetic patterns and 16 processes. This work aimed to determine the time length of embryonic development 17 at different temperatures, and if the egg size is a determinant of hatchling size in 18 Sepiola atlantica d ́Orbigny, 1839-1842. Successful hatching occurred ...
