Celebrating the rain, the wind, and the departure of sun. For tomorrow.

暂时来一段小插曲。

Australian Town: giant tyres, dry pool, and closed shop

澳洲，人口密度世上属第三最低。离开城市，大部分地区都只见物不见人。

我们都是草的种子

每一根草的摆动，象征着时间的流逝。我们都是草的种子，随风飘逝，前方未定。

Perth, 6am

六点钟，西澳首府。

提早上班的人儿，发呆了一秒钟。
暂时被遗忘的车，冷冻发臭的宵夜。

机械性却暂无作用的红绿灯。

飞翔的海鸥。

榕（之一） · Figs #1

“路边一颗榕树下，是我怀念的地方。”

榕树象征岁月。市镇中，每一条半悬的根记录着当地的人文历史；森林中，则记录着鸟语虫鸣。拨开榕树的“胡须”，仿佛就能听见遥远及古老的笑声。

人之渺小、人之宏伟

横看成岭侧成峰，
远近高低各不同。
不识庐山真面目，
只缘身在此山中。

苏轼（1037－1101）

不难想象 60 年代末，人类第一次看见地球全面貌时的惊讶。当时，我们懂山懂海，却首次目睹脚下星球的全景。不过此创举却还未让我们看见全宇宙。

如今我们已经看见了太阳系，但许多人却仍懊恼于每日的琐碎事（请观赏 Jason Pontin: Can technology solve our big problems?）。人类尚有许多进步进化空间。美国著名科学作家 Carl Sagan 说 we are a way for the universe to know itself。谦卑地接受自己的问题只是人生中一则小事，生活不只是为了自己，也是为了身边的大家。

Magnolia · 玉兰

超过 2 千万年前，这朵花已经盛开。你我之间振动的分子，是 460 亿年内何时播下的种子？

该丢掉的，总该丢掉

一些过时的东西，该扔掉就该扔掉，尤其是坏习惯和过时的思想。

Searching for the endangered shrub, Persoonia hindii

The latest field work was an interesting one: chatting all day long about community assembly processes and methodology for quantifying spatially-clustered plant population. Put it in a simpler way, we were measuring the population size of an endangered shrub, Persoonia hindii, while investigating what is the plant's suitable habitat.

Ray navigating to the next survey transect through open eucalypt woodland, dominated by a ground layer of Pteridium ferns.

As community ecologists, we were not interested only in the "well-being" of a single plant species, but were also observing the neighbour species and the environment in which they live. These biotic and abiotic associations will allow us to predict habitat requirements of the focal species (i.e. P. hindii).

A fruit-bearing Persoonia hindii, which is listed as endangered under NSW government. Our recent tracks covered an area of about three football fields (within an 40km² forest area), but only found the plant within 6.5% of the total area.

What's the point of this field survey? The investigation area is being disturbed by coal mining. Trees are being cleared to pave ways for water-discharge pipes. Legislation however demands the mining company to reassess its impact on local ecosystem including endangered species such as P. hindii. Our data will help mapping the locations where P. hindii occurs in high density (i.e. species distribution model), and mine managers will be required to avoid cutting their pipes through these hot spots.

Roadside logging for the construction of a mine water-discharge pipeline. Habitat destruction at forest edges will impact inner vegetation through "edge effects", such as increased erosion, sunlight and cut-off animal movement (which is vital for pollination and seed dispersal).

成长的方向 · 东指西指 · 去哪里？

我们都已经长大，但前方的路还长。地球很大，社会很复杂，并不是说指哪里就能到哪里，但每日都是一步一步向目标迈进的过程。

让我们看看，白头那日，身边会有谁高杯谈昨日那些年。
