I've always admired her. She was such an intelligent, strong female scientist. Inspired hundreds of women to join science. But besides all of that she was so kind to everyone. This world often sees kindness as a weakness, but a person like her shows that our words are absorbed better if they're soft

Our new paper @asn-amnat.bsky.social develops a Grand Unified Theory including both exploitative and interference competition doi.org/10.1086/737628. The R* rule of ecology (that 2 species cannot coexist on a single resource), is widely broken, including via a new trade-off we describe. 1/9

Abstract Many ecological models treat exploitative competition in isolation from interference competition. Corresponding theory centers around the R* rule, according to which consumers that share a si...

1/ Invasional meltdown is a popular but nebulous concept in invasion ecology. It involves multiple direct & indirect mechanisms, yet it is rarely studied beyond simple pairwise facilitations.

NEW: 2024 has just been confirmed as the warmest year on record, and the first to breach the 1.5C threshold.

We used a ridgeline (Joy Division inspired) chart to visualise daily temperature anomalies since 1940.

2024 clearly stands out with 100% of its days above 1.3C and 75% above 1.5C.

Ridgeline chart showing the distribution of global daily air temperature differences from the pre-industrial reference period (1850-1900), for every year between 1940 and 2024. Each individual year resembles a hill, shaded in a darker shade of red and further to the right for warmer years. The trend is clearly towards warmer years, with 2024 standing out as first year above 1.5C.

A major challenge in restoration ecology is the widespread belief that there is a correct natural community for any given location, and that identifying it is the first step in recreating it. 1/6

Temperate rain forest image taken from the Wildlife Trusts website. This is one of the most contentious habitat types to define, partly because so little remains in Europe, which makes it a difficult target for restoration. https://www.wildlifetrusts.org/habitats/woodland/temperate-rainforest

As women in academia, having children can feel impossible. Talking about it makes us feel less alone

The struggle is “balancing their careers not just with motherhood, but with what comes before: relationships and planning for a family,” these postdocs write
