New paper 🐦
Multi-trait syndromes explain dispersal among close relatives, but simple traits (e.g. body mass) better predict across species.
A case for simpler, mechanistic ecology.

Figure 1 Hallinger (2026): Responses of immigrant and local female life history to variation in breeding environment. Lines represent marginal effects of the y-axis variable predicted from general and generalized linear mixed-effects models with the R function ggpredict() (Lüdecke, 2018). Shaded areas represent 95% CIs. To reduce point overlap and improve visualization of differences between immigrant and local females, points in panel (b) are jittered slightly on the x-axis, points in panel (e) are jittered slightly on the y-axis at y = 1, and points in panel (f) are slightly transparent.

The Heroes Fall
Many funerals
For unspoken figures
Many possible personas
All imagined with mere seeds of reality
Unspoiled and unsprouted
I do not fail to attend the wakes
For I was there
When they were born
And died
By my own entropy
Not by choice
Eyes like mine
Only when closed

Conceptual figure. (A) Seeds dispersed from a parent plant to focal plants may either be not trapped or retained, trapped but not retained, or trapped and retained. (B) The authors hypothesize that due to physical attributes (i.e., size and growth form), plant species could be good trappers, but not good retainers (species 1), vice versa (species 2), or have similar trapping and retention probabilities (species 3).

Aristolochia fruits are a marvel. Some, like A. dictyophlebia, are berry-like (the former Pararistolochia), but many are wonderful baskets, like this A. ringens, from which the flat seeds sift into the wind. #Aristolochiaceae #TropicalBotany #dispersal #Botany 🌾🧪🌱

Microbial movement into soils occurs at a surprisingly local scale. By measuring dispersal rates and spatial patterns, this study challenges the assumption that microbes freely mix across environments.

🌱 How far can plants really shift their future range under #climatechange? Using #SDMs for 1318 European species, this study shows that most #plants can’t track shifting climates.
⚠️ Authors suggest caution in assuming #dispersal capability in SDMs.

Fig. 1. Palaeo-location of the 27 regions of A) conodont and B) ammonoid taxa taxa defined in this study, respectively. Each region is associated to its number of sampled localities encircled by five arcs, each arc corresponding to a time interval (Changhsingian, Griesbachian, Dienerian, Smithian, or Spathian). A coloured arc means that the region includes at least one locality dated from this time interval; an unfilled arc means that the region does not include any locality dated from this time interval. See the section Material and methods for details about the calculation of the palaeocoordinates. Silhouettes of conodont and ammonoid are public-domain images from the Phylopic website (compare https://doi.org/10.18261/let.58.3.2).
Values of Dispersal-Niche Continuum Index (DNCI) show ammonoid biogeography was dispersal-constrained in Griensbachian and Spathian as opposed to niche constrained in the Smithian, while conodonts were more functionally (niche) constrained in Griesbachian as opposed to driven by both niche and dispersal constraints from the Dienerian to Spathian. Black dots and associated horizontal black lines represent mean value and ±2 standard error, respectively.

A close-up photo of a bug climbing on a plant shoot. The bug is all black with red spots.
It blows my mind that red-&-black fruits and seeds are attractive, but red-&-black insects are repellent (aposematic). In dispersal, as in life, context is everything! 📷1: Ripe fruits of Pinanga malaiana (#Arecaceae). 📷2: red-spotted stink bug, Jose Amorin CCBYNCSA2. #dispersal #Botany 🌾🧪🌱

Photo of the foliage and fruits of noni. The fruits are multiple fruits and are white when ripe. Photo by Scott Zona CCBYNC2.
White fruits are relatively rare in plants. Birds don’t detect them very well because they have low chromatic contrast with background vegetation. Mammals can more easily detect white fruits if they are aromatic, like this stinky Morinda citrifolia #dispersal #Rubiaceae #Botany 🌾🧪🌱

The fleshy sarcotesta of Ginkgo biloba smells really nasty. Some biologists suggest that the stench evolved to attract scavenging dinosaurs (or ancient mammals), which dispersed the seeds. 🤷♂️ Maybe. If so, that vile smell is the aroma of Jurassic death. 💀 #dispersal #Ginkgoaceae #Botany 🌾🧪🌱

Photo of a hand holding a fruit cut in half. The fruit is brown and has a thick husk. The seeds are embedded in a gelatinous matrix surrounded by firm flesh.
Another part of mammal dispersal may be ethanol. It’s repellent at high concentration but attractive at low concentration. Mammals may zero in on the aroma for efficient foraging. Genipa americana (📷: Cody Hinchliff CCBYNCSA2) ripe fruits have ca. 0.5% ethanol. #dispersal #Rubiaceae #Botany 🌾🧪🌱

Photo of fruits on a cutting board with a paring knife. Fruits are ovoid and greenish-yellow. One is cut in transverse section to show a creamy yellow interior and large seeds.
Mammals tend not to have color vision, so plants advertise with aromas. The fruits tend to be green, brown or white & require manual or buccal processing to remove a husk or large seeds. A good example: pawpaw, Asimina triloba (#Annonaceae). #dispersal #Botany 🌾🧪🌱

Photo of leafy shoots of blackberries. Some fruits are red and unripe. Others in the same cluster are black and ripe. Photo by Scott Zona CCBYNC2.
Stiles also hypothesized that a “preripening” fruit color is a signal that fruits will be ripe soon. Lots of fruits, like these Rubus sp., pass through a 2nd color as they ripen from green to their final color. The red color says, “Coming Soon.” #dispersal #Rubiaceae #Botany 🌾🧪🌱

Photo of leafy shoots bearing blue berries. A leaf subtending a cluster of berries has turned bright coppery red.
In the 1980s, E. Stiles hypothesized that plants advertise fruit with a contrasting foliar “flag.” I’ve seen this phenomenon in cultivated Berberis, like this B. aquifolium (📷: Alicia CCBYNC4). Some experiments support the hypothesis; some don’t. 🤷♂️ #dispersal #Berberidaceae #Botany 🌾🧪🌱

Helping animals find fruits: Plants advertise to bird dispersers via colorful fruit. Red fruits stand out in the visible spectrum, like these Ilex vomitoria fruits, but they may also contrast with the foliage in the UV spectrum, which birds can also see. #dispersal #Aquifoliaceae #Botany 🌾🧪🌱
