8 years ago I started monitoring the Marakele wild elephants and dreaming of one day studying their communication. Today my first wild elephant paper exploring intentional gestural communication in the Marakele and Addo populations is out, marking a key personal moment 🐘❤️. rdcu.be/87qLLG6DSs7a 1/4

Great use of the tens of thousands of dwarf mongoose body mass measurements collected over the years. Animals vary substantially in mass across days and seasons - when determining if a tag is too heavy we need to think about how light an animal might become, not just its mass right now.

3/4 Using data from 101 wild cooperatively breeding populations of #birds and #mammals, our study highlights the need to (i) uncover the conditions that favour the formation of multi-female groups, and only then (ii) to identify those conditions that support the realisation of female cooperation.

Statement by the Senate of Tel Aviv University
Statement by the Senate of Tel Aviv University
For a long time now, we have been witnessing acts of violence by Jewish residents in the West Bank against Palestinian residents. These acts, which include severe harm to persons and property, intimidation, humiliation, and displacement, have in some cases escalated into shocking acts of murder. These phenomena have intensified over the past month, under the cover of the war with Iran.
As citizens of the State of Israel, we bear a heavy moral responsibility and feel deep shame in the face of this rampant Jewish terrorism. We protest the failure of the government and security forces to act with the necessary resolve against this phenomenon by using all means at their disposal. Terror directed against innocent civilians does not change according to the identity of the perpetrator or the victim; terror is terror, and it must be eradicated.
The State of Israel, as the authority responsible for the territories, bears a clear obligation under both international and Israeli law: to ensure the safety and well-being of all residents, Jews and Palestinians alike. Beyond this legal duty, the government bears a paramount moral obligation: not to permit the shedding of blood in the West Bank, whether by action or by failure to act. As a people who have experienced pogroms and persecution driven by racism, we are bound to remember where such a path may lead. We must not stand idly by.
History teaches us that in times of war, human rights are often pushed to the margins in the name of the demands of the moment or the pursuit of victory. We refuse to accept this reality. Jewish terrorism serves no legitimate purpose; on the contrary, it erodes the very foundations of our existence. Silence in the face of terror from within is a moral stain that cannot be erased, for the strength of the State of Israel is measured not only by its military power but first and foremost by the integrity of its values.
