Abstract:

We studied the reproduction patterns of Squacco Herons, Ardeola ralloides, during 2009–2010. This study was carried out in two colonies located at Ichkeul National Park (37.184992 N, 9.633758 E) and Lebna Dam (36.744161 N, 10.916569 E), in northern Tunisia. We determined the reproductive performance of the species, and investigated the relationship between reproductive parameters and nest characteristics (height and diameter). We registered successful nesting, with mean clutch size of 4.51 ± 0.85 for both years combined. Hatching success was 3.67 ± 1.07 eggs hatched/nest and fledging success reached 3.06 ± 1.28 young/nest. All reproductive parameters varied between years. The diameter and the height of nest had no effect on the clutch size, the initial brood size, or the final…

Tunisian cultural workers protest

Cultural workers in Tunisia began a three-day strike on July 9, impacting festivals and similar events. One expected to be affected is the International Festival of [Carthage], which is the largest in the country and takes place from [July] 10 to August 16.

The workers had held a three-day strike in June. They are also calling for an investigation into corruption in the National Institute of Heritage for the publication of financial and administrative data relating to the national library service. In addition, they are opposing plans to privatize some Tunisian archaeological sites and museums.

Saudi Arabia jails prominent human rights activist for 15 years

Waleed abu al-Khair was imprisoned on charges that included seeking to undermine the state and insulting the judiciary

Antonia Molloy

Prominent Saudi human rights lawyer Waleed abu al-Khair has been sentenced by a Jeddah court to 15 years in prison for crimes including “inciting public opinion”.

Abu al-Khair, the founder and director of an organization named the Monitor of Human Rights in Saudi Arabia, was jailed on Sunday on charges that included seeking to undermine the state and insulting the judiciary, the state news agency reported.

He had been on trial on sedition charges that included breaking allegiance to King Abdullah, showing disrespect for authorities, creating an unauthorized association and inciting public opinion.

The rights activist was also fined 200,000 Saudi riyals (£31,100), banned from travelling outside the kingdom for another 15 years and had all his websites closed down, the SPA said.

Abu al-Khair was critical of a new anti-terrorism law passed by Saudi Arabia at the start of the year which was widely condemned by rights activists as a tool to stifle dissent.

The anti-terrorism law states that terrorist crimes include any act that “disturbs public order, shakes the security of society, or subjects its national unity to danger, or obstructs the primary system of rule or harms the reputation of the state”.

In the past year Saudi authorities have been criticised by international rights groups for jailing several prominent activists on charges ranging from setting up an illegal organisation to damaging the reputation of the country.

In May a client of Abu al-Khair was sentenced to 10 years in jail and 1,000 lashes after being arrested in June 2012 on charges of cyber-crime and disobeying his father.

Raif Badawi was the editor of the Free Saudi Liberals website, which included articles that were critical of senior religious figures such as Saudi Arabia’s Grand Mufti and allegedly insulted Islam and religious authorities, according to Human Rights Watch.

Abu al-Khair was unable to represent Badawi in an appeal because he was also in jail at the time, awaiting his trial in the ultra-conservative Islamic kingdom.

Passerine abundance and diversity in a polluted oasis habitat in south-eastern Tunisia

Posted on 27/05/2014

Alaya-Ltifi, L., & Selmi, S. (2014). Passerine abundance and diversity in a polluted oasis habitat in south-eastern Tunisia. European Journal of Wildlife Research, 60: 535–541. doi:10.1007/s10344-014-0817-0

Abstract:

Gabès region, in south-eastern Tunisia, is nowadays considered as one of the most remarkable pollution hotspots in the Mediterranean due to the emissions of the Gabès-Ghannouche factory complex of phosphate treatment. However, because of the lack of detailed studies, the impact of such pollution on the terrestrial wildlife inhabiting this area still remains unknown.

In this work, we checked whether the proximity to Gabès-Ghannouche factory complex was associated with a decreased abundance of passerines breeding in the neighbouring oasis habitat. Overall, passerine abundance was found to decrease in the proximity of the factory complex, but this decrease was more pronounced in insectivorous species than in granivorous ones. The latter species seemed to be more dependent on vegetation structure. Moreover, we found that in the sites close to the factory complex, the studied passerine community was dominated by the Sparrow Passer domesticus × hispaniolensis, which seemed to be the less sensitive species to pollution.

However, in the more distant sites, passerine abundance was more equitably distributed among species due to the increase in the densities of pollution-sensitive ones. Our findings give support to those reported in polluted European forest habitats and stress once again the usefulness of passerines as reliable biomonitors of polluted terrestrial environments.

Tunisian fossil primate discovery

NOVA scienceNOW: 41 – First Primates.

From ScienceDaily:

Fossil Primate Shakes Up History of Tooth-Combed Primates

Dec. 11, 2013 — Fossils discovered in Tunisia challenge several hypotheses concerning the origin of tooth-combed primates (Malagasy lemurs, Afro-Asian lorises and African galagos). The fossils are of a small primate called Djebelemur, which lived around 50 million years ago. They were discovered by a French-Tunisian team from the Institut des Sciences de l’Evolution in Montpellier (CNRS/Université Montpellier 2/IRD) and the Office National des Mines (ONM) in Tunis.

According to the paleontologists, Djebelemur was probably a transitional form leading to the appearance of tooth-combed primates. However, according to genetic data, these primates appeared at least 15 million years earlier. Djebelemur therefore challenges the hypotheses put forward by molecular biology. The work, which has just been published in PLoS One, makes it possible to reconstruct a chapter in the evolutionary history of this lineage. In addition, it may help to refine genetic models.

Tooth-combed primates, also called strepsirrhines, comprise lemurs and lorisiforms (small primates which include lorises and galagos). In these primates, the anterior teeth of the lower jaw take the form of a comb. This is mainly used for grooming, but also, in some species, for procuring the natural gums that make up part of their diet.

A key question debated by primatologists concerns the time when strepsirrhine primates first appeared. Recent genetic data dates the origin of lemurs and lorises to the onset of the Tertiary period, just after the disappearance of the dinosaurs (approximately 65 million years ago). Some molecular biologists even believe that divergence of the two groups occurred 80 million years ago. However, paleontological data does not corroborate these hypotheses: the oldest known lorisiform fossil dates from a mere 37 million years ago. Could this simply be due to a gap in the fossil record? The fossils discovered by the Institut des Sciences de l’Evolution in Montpellier (CNRS/Université Montpellier 2/IRD) and the ONM in Tunis suggest otherwise: it is the genetic models that may need to be revised.

Discovered in the sediments of a former lake in Djebel Chambi National Park, Tunisia, the approximately 50 million-year-old fossils belong to a small primate called Djebelemur (lemur of the Djebel). This was a tiny animal weighing scarcely 70 g. It was most certainly nocturnal, a predator of insects and a tree-dweller. Some of its morphological characteristics suggest that it was a distant relative of lemurs, galagos and lorises. However, although it did not yet have such a specialized toothcomb, it exhibited a tooth structure that had already been transformed, an early stage of the anterior dentition of today’s strepsirrhines.

Djebelemur thus appears to be a transitional form, pre-dating the lorisiform-lemuriform divergence. Therefore, tooth-combed primates probably did not originate as early as molecular biologists have claimed. This is likely to have occurred less than 50 million years ago, the age of the Djebelemur fossil.

This is not the first time that genetic data disagrees with paleontological data. For many groups of mammals, geneticists tend to put forward earlier dates of origin than those provided by direct observation of the fossil record. Molecular biology increasingly seeks to refine its models by constraining them with fossil data. In the case of the origin of tooth-combed primates, Djebelemur could prove to be a significant milestone making it possible to reset the molecular clock and improve estimates of divergence dates derived from molecular phylogenies.

Tunisian women’s forced prostitution in Syria


This video says about itself:

28 March 2013

The Tunisian Minister of Religious Affairs has rejected a so-called ‘sexual fatwa’ that calls on young Muslim girls to show their support for Syrian Islamist fighters by providing them with sexual services.

Translated from NOS TV in the Netherlands:

Saturday 17 Aug 2013, 10:10

Hundreds of women, particularly from North Africa and the Middle East, are in the “sex jihad” in Syria. They are often lured under false pretenses to the country to provide sexual services to the fighters.

Correspondent Frank Renout spoke with a Tunisian lawyer, much of whose work is about jihadists. During his work he found out about Tunisian women who went to Syria. According to the lawyer, they were mainly recruited in mosques where the women were told that supposedly a bright future awaited them.

“For example, people tell them they will find a bridegroom in Syria. And that, for some Muslim women, is a ‘ticket to heaven’” says Renout. “If they marry a Muslim warrior who dies during the jihad, then not just he is supposed to go to heaven, but they also get a license to go to heaven.”

Enforced sex

Upon arrival in Syria, it often turns out it is just about sex. In some cases it is enforced sex. Women who returned to Tunisia were sometimes pregnant and told about rape, the lawyer said.

Also families knocked at the lawyer’s door who had lost their daughters. Who proved often to also have been recruited and who are in Syria now.

European experts on illegal killing of birds draft action plan in Tunis

At the end of May bird conservation experts met in Tunis at the Week on Conservation of Birds to identify ways forward to tackle illegal killing of birds. During the event, BirdLife Europe Partners shared best practices on key issues, such as bird poisoning, law enforcement measures and awareness strategies. The focus of the conference, organised by CMS and the Council of Europe, was to identify specific actions and priorities to work on, with the goal of ensuring the recovery of especially migratory birds protected by the CMS and Bern Convention.

Attendants reinforced their position on minimizing migratory bird poisoning, considered as “the one cause that probably has the highest conservation impact”, as Willem Van den Bossche, Nature Conservation Officer at BirdLife Europe stated at the meeting.

On the same subject, SEO (BirdLife in Spain) presented the outcomes of the LIFE+ project VENENO, which is bringing governmental authorities, environmental police and NGOs together. The project aims to fight against poisoned baits, identified as one of the main reasons behind migratory bird deaths, together with rodenticides, lead, veterinary drugs and insecticides.

The participants at the Week on Conservation of Birds prepared a draft action plan to reduce the illegal killing of birds. “When approved and linked to the EU roadmap towards eliminating illegal killing, trapping and trade of wild birds this will be a good tool to measure progress and results of the actions and to strengthen cooperation between stakeholders within the whole flyway of migratory birds”, says Willem Van den Bossche. In that sense, the Bern Convention, a treaty which recognises that European wildlife and habitats need to be preserved and handed on to future generations, is seen as “an opportunity for North African countries which are parties to the Convention to cooperate and protect important bird areas for migrating birds by including them in the Emerald Network, a network similar to Natura 2000 but outside the EU for protecting nature sites”, stresses Claudia Feltrup-Azafzaf, Executive Director at Association “Les Amis des Oiseaux” (AAO) – BirdLife in Tunisia.

At the conference BirdLife Cyprus explained its experience on taking cases into courts to prove that mistnets and limesticks are threatening many migrant birds travelling through the island, and insisted on promoting institutional collaboration and pushing law enforcement to address the issue. Another example was provided by BirdLife Malta. In Malta the law enforcement of illegal trapping and killing of protected birds still needs to be enhanced.

Effects of windfarms and powerlines on migratory birds were also analysed during the meeting. The research info and guidelines that will be produced in the follow-up of this conference will be extremely useful to ensure the zero tolerance approach to illegal killing all parties agree on.
