The shrew’s extinction increases the tally of Australian mammals extinct since 1788 to 39 species. This is far more than for any other country. These losses represent about 10% of all Australia’s land mammal species before colonisation 🧪

Can birders please stay out of the conservation area/ ringing rides at South Landing please. If looking for the Barred Warbler please view only from the car park

10/ Finally, the 2023 IPBES report is the most comprehensive global assessment of non-native species ever conducted. It gives unequivocal evidence that invasions threaten biodiversity & ecosystems - thus contradicting claims that concern over invasions is unwarranted.
www.nature.com/articles/s41...

9/  The global rate of species introductions has shown no sign of saturation. Under human influence, species are moving exponentially faster, farther, & in greater numbers than at any other time in Earth's history, creating novel evolutionary pressures on naive biotas. www.nature.com/articles/nco...

8/ Invasions interact with other global stressors (climate change, organic pollution, land use) in unpredictable, synergistic ways. Stressors may trigger even benign nonnative spp to become disruptive. Such interactions pose major challenges for ecosystem management.

7/ Due to proliferating human vectors, increasing numbers of novel predators, pathogens & ecosystem engineers are being introduced to insular systems (lakes, islands) and to regions whose communities have no evolutionary experience with such species and are therefore vulnerable to disruption.

6/ Although some native species can also become superabundant & damaging (but only when triggered by disturbance), non-native species are far more likely to be implicated as a cause of global extinction:

5/ Paleontological evidence also links invasions to mass extinction - and suggests that modern human-assisted invasions may similarly result in the “extinction of geographically restricted ecological specialists and suppression of vicariant speciation of new species".
www.cbc.ca/news/science...

4/  An analysis of the IUCN Red List (described as "the world's most comprehensive inventory of the global conservation status of biological species") implicates invasions as a major cause of extinction over the past 500 years.

3/ Evidence from various studies (some shown below) & taxonomic groups have implicated invasions as the sole or contributing cause of a large proportion of global animal extinctions.

An additional line of evidence comes from recoveries of native species following invasive species eradications.

2/  The impacts of the vast majority of #bioinvasions have not been studied.

Most non-native species are assumed to be benign. A small fraction (but an increasing total number) of invaders are shown to have substantially altered ecosystems and caused local, regional, and global extinctions.

1/🧵 Over the past decade, misinformation in the popular media & the opinion pages of some journals has promoted the claim that concern over species invasions is overblown, because "most invasions do not cause extinctions".

Here is a brief reminder of what scientific evidence shows...

Today IUCN has officially declared the Slender-billed Curlew extinct, marking the first known global extinction of a formerly widespread migratory bird species whose range included mainland Europe, North Africa, and West Asia.

This was #sophiefromromania at 6.30 being told it was far too early for a walk. Soon after 7 we were out with her

Rangers are on the frontlines of conservation, protecting our natural and cultural heritage for the benefit of all.

Today at #IUCNcongress, with our partners, we proudly reaffirmed our commitment to the Universal Ranger Support Alliance, which advocates for and supports rangers around the world. 🌍

Twice a year, we celebrate #WorldMigratoryBirdDay 🐦🌍

Reflecting the rhythm of bird migration, it is our chance to safeguard birds and create bird‑friendly #SharedSpaces 🏡

Have a closer look at this year’s ambassador birds 👇

Semana 13-19 de octubre: más cálida de lo normal en casi todo el país, salvo tercio oriental peninsular y Baleares. En estas zonas, además, lluvias superiores a las habituales; en el oeste serán inferiores.

Predicción para las próximas tres semanas 👉

aemetblog.es/2025/10/10/p...

🟠 Avisos naranjas (peligro importante) por lluvias en la Comunitat Valenciana, Región de Murcia e Illes Balears para el sábado, 11.

En zonas de Mallorca, Ibiza y Formentera podrán acumularse más de 100 mm en apenas tres o cuatro horas.

¡Extrema las precauciones!
