According to India's first elephant census since 2017, the Asian elephant population has declined by 25% in 8 years, with electrocution, railway collisions, poaching and habitat loss as the leading causes of elephant deaths.

🛡️ Protected areas (PAs) are a cornerstone of biodiversity conservation. But how do we know whether they truly work? We reviewed 275 articles & 280 studies to map how terrestrial PA effectiveness is measured. Here's what we found:

How is the effectiveness of terrestrial protected areas to conserve biodiversity measured?
This systematic map aims to collate and synthesize global evidence on the methods and metrics used to assess the effectiveness of terrestrial PAs in biodiversity conservation.

After a long absence from Twitter, I'm now on Bluesky. Looking forward to sharing thoughts, research, and rants about the lack of attention paid to water. Let's kick this off with a new paper alert. Please share widely. Title says it all. Please help me grow followers www.science.org/doi/10.1126/...
Unprecedented continental drying, shrinking freshwater availability, and increasing land contributions to sea level rise
Drying continents, extreme drought, and groundwater depletion are shrinking water availability and increasing sea level rise.

Drawing on data from over 400 forest plantations in Himachal Pradesh, India, we show that improved forest outcomes (increasing forest cover, improved forest-based livelihoods) are strongly associated with long-term participation by local people in decision-making. iopscience.iop.org/article/10.1...

The biggest publishers pulled profit margins in 2023 that rival Big Tech.

And they still charge you to publish and your library to read.

When are we going to start seriously thinking of alternatives to reform #PeerReview?

🧪 #SciPub #AcademicPublishing
Where is the money going? In the case of for-profit publishers it's very clear:

Your open access fees fund corporate profit margins.

Profit margins for large academic publishers can far exceed those of household names like Amazon and Apple.

Ten dead in ‘brutal’ attacks by Isis-linked militants on Mozambique wildlife reserve | Global development
One of Africa’s largest protected areas has been shaken by a series of attacks by Islamic State-linked extremists, which have left at least 10 people dead. Conservationists in Niassa reserve, Mozambique, say decades of work to rebuild populations of lions, elephants and other keystone species are being jeopardised, as conservation operations grind to a halt. On 29 April, militants attacked buildings in Niassa…

Excellent article covering a new systematic review of restoration in the Western Himalayas. Concerning findings, similar to my work, are that restoration has tended to focus on (not very successful) tree plantations on govt. land, with overuse of exotic species: india.mongabay.com/2025/05/unpa...

The first roads that slice through rainforests are widely recognized as pathways for #deforestation. However, new research reveals that secondary roads—those branching off from main roads—are responsible for significantly greater forest loss than the primary roads themselves.

On #InternationalDayofWomenandGirlsinScience let me remind you that we are NOWHERE NEAR parity. A few examples.

1. Women are credited less in science than men.

Women are credited less in science than men - Nature
The difference between the number of men and women listed as authors on scientific papers and inventors on patents is at least partly attributable to unacknowledged contributions by women scientists.
