Jackson, Ron. Wine Science Principles and Applications Plate 9.1 – Cluster of grapes at different stages of rot.

The fungus Botrytis cinerea — a type of gray mold — is the kind that grows on the old berries in your fridge, but in the vineyards of Europe (and more recently some other wine-producing regions artificially infected, but more on that later) B. cinerea doesn’t always turn valuable fruit into a furry mush. Also known as noble rot, B. cinerea has the potential to positively change wine grapes, in the right conditions. Depending on a vineyard’s microclimate, infection can result in either gray rot, which essentially ruins the grapes, or noble rot, which leads to unique dessert wines such as the Tokaji Aszú of Hungary, the higher Prädikat wines of Germany, and the Sauternes of France (the most prized of which can fetch $750 a bottle!).

In a single vineyard there can be completely healthy grapes, grapes with gray rot, and grapes with noble rot, all in close proximity to each other. The required conditions for noble rot formation are incredibly narrow. Like with most fungi, humid conditions favor formation. However, alternating dry and rainy periods, particularly frequent morning fogs, are necessary for the formation of asexual conidia (spores). Therefore, noble rot seldom occurs in hot and dry areas, since sunny and windy conditions allow more water evaporation. Continue reading

Animal Behavior: The Osa Peninsula

On a recent trip to the Osa Peninsula for a couple of days, and one herpetologically-rich night, I found a number of the types of animals that make Costa Rica such a popular destination for wildlife-lovers. The Osa is home to about half the species that Costa Rica boasts, making it the most biodiverse spot in the country — or even the world. The density of fauna seen on any hike through the forest back up the statistics (2.5% of the earth’s biodiversity just on this little peninsula?!), and I was glad to be able to get some video of typical animal behavior during my time there.

Roots and Seeds at Xandari

Back in the beginning of July, James and I helped José Luis plant some Bourbon coffee seeds so that they would eventually become seedlings that could be put in bags to grow into saplings. Now, after months of watering and patience, many of the seedlings are finally beginning to emerge. As more and more of them germinate and create their shoots, we’ll be putting them into the bags with soil to wait another year before planting them in the ground at Xandari.

Plenty of other plants have been productive over the last couple months: Continue reading

A Night Walk in the Osa Peninsula

I recently went on a night walk in the rainforest of Costa Rica’s Osa Peninsula, looking for frogs, snakes, and other nocturnal animals with a great wildlife guide who knew the area well. Although we didn’t see any mammals or the famous deadly Bothrops asper viper known as the “terciopelo” in Spanish (velvet) and “fer-de-lance” in French (spearhead). We did, however, see numerous frog species and at least two snake species, although we could only identify the six or seven Cat-eyed Snakes we saw.

There were also some basilisk lizards getting bit by mosquitoes, a large spider similar to a tarantula, a dragonfly larva in the water, and plenty of frog eggs. At one point we turned off all our flashlights to try to find a glass frog (pictured below) and noticed some bioluminescent mushrooms, which were impossible to photograph in the dark and look pretty dull in the light. Although I’ve forgotten the names of the various frog species featured in the slideshow of the photos I was able to take below, I hope you enjoy Continue reading

Conquering Iceland’s Mountains: The Alpine Club (Part 3)

Continued from Part 2.

As it turned out, it was a British law student, William Lord Watts, who became the first man to truly answer Longman’s call and embark on some serious exploring. In the introduction to his book Across the Vatna Jökull; or, Scenes in Iceland; Being a Description of Hitherto Unknown Regions, Watts started by taking issue with the concerned British subject at home who saw the exploration of wilderness as a waste of “money, time, and labour,” or “utter folly,” explaining that everyone had a mania for something or other, and his own “may be to wander amongst unknown or unfrequented corners of the earth.” Calling for “a truce to critical stay-at-homes,” Watts advanced to the meat of his trip itself.

In his descriptions of his several expeditions, Watts usually employed a calm, scientific and lawyerly tone that make his bursts of romantic and athletic enthusiasm in certain scenes all the more exciting and believable. Nodding to his biggest audience, he also used some of the Continue reading

Conquering Iceland’s Mountains: The Alpine Club (Part 2)

Continued from Part 1.

If Longman’s unorthodox address is interesting as a sign of Iceland’s attractiveness to the middle-class British authentic-seeking traveller, the responses to his suggestions are even more so. In a May 18 article The Critic wrote a review of the Longman’s address that effectively summed up the perceived position of Iceland in the global context of travel and exploration. The author suggested that any adventurous Briton who had already “used up Ireland and Scotland” and “[did] not care to ascend Mont Blanc for the dozenth time” might turn to Iceland for their future travels, as it had spectacular scenery equal to Switzerland and critics were growing tired of “oft-repeated tales” in countries they knew intimately through so many books. The contributor continued by explaining that:

We do not ask the good-natured traveller to kill gorillas in Africa after Mr. Du Chaillu’s fashion, or hunt bisons on the American prairies with Mr. Grantley Berkeley. Our request is much more reasonable. Iceland may be reached by the expenditure of a single five-pound note: and in that uncockneyfied land a solitary Englishman may pay all his daily travelling expenses, including those which will be entailed on him by a retinue of three horses and a guide, for twenty shillings.

Conquering Iceland’s Mountains: The Alpine Club (Part 1)

It has been months since I’ve mentioned Iceland on the blog, partly because I was exhausted with the subject after completing my thesis in mid-April, but also because I’ve been occupied with less academic matters over the summer. Another reason for revisiting the topic is that over the summer I had the honor of learning that my thesis was added to the Kroch Library Rare and Manuscript Collections–hopefully somebody will find it useful eventually! Now that the volcanic dust has settled and the borrowed library books have been returned, I feel there are a couple facets of nineteenth-century British travel to Iceland left to explore here.

I’ve written about some of the qualities exhibited by British travelers to Iceland before, but Continue reading

Throwback Thursday: Anteating Howler Butterflies

This post was originally published on August 2nd, 2011.

While walking to Morgan’s Rock’s lobby yesterday morning, Pierre heard some rustling in the bushes on our right. We looked for the source and were stunned to see an anteater standing on its hind legs, spreading its arms and swaying about like a drunkard but in fact trying to dissuade us from attacking it by trying to appear larger (it was bigger than a very fat house cat, but not by much). I immediately pulled my video camera from my pocket and started filming, and although the anteater had ceased his humorous movements and started climbing a very thin sapling, the footage was incredibly fortunate and very entertaining.

Since the tree he decided to grasp was so young, it started to bend as he climbed higher, reminding me of cartoons where characters are catapulted out of the branches after a certain point. The anteater was less than a meter away and at times looked like a teddy bear, but as a wild animal—and one with claws in full display at that—we refrained from touching him and were satisfied with a video. Eventually, the formicary raider descended the sapling and chose a better escape tree (in a pose reminiscent of the boa’s in a previous post), and we left happy with the sighting of what I thought I’d only be able to see in the summer when foliage was less dense.

Some Animal Behavior Footage from Costa Rica

A dragonfly on a path at Xandari

Whenever I have the opportunity to visit a national park in Costa Rica, I obviously take my camera with me so I can try to get some good photos or videos of all the wildlife I hope to see. Looking back on my files of images from the past couple months, I realized that I happened to have some half-decent videos that represented what I’d consider the four most important classes of Kingdom Animalia/Metazoa from the point of view of a terrestrial biophile: Aves, Reptilia, Mammalia, and Insecta. In other words, when I’m walking through the rainforest, the animals I keep an eye out for will likely fall into the category of bird, reptile, mammal, or insect. If I’m out at night, then maybe Amphibia will get thrown in there too!

In the video above, you can  Continue reading

eBird Expansion

Including historical data since 1810 and extending into checklists from December of last year, eBird’s Observational Dataset just hit a milestone of 500 million records, making eBird the largest repository of biodiversity information that is freely accessible.

Goats and Gallinas at Xandari

The chicken coop with two visiting turkey neighbors

At Xandari, right by the orchard and the greenhouse, you can find pens with a good thirty-something chickens, two goats, and three turkeys. Providing eggs for the restaurant every day, the chickens — or gallinas, as they’re called in Spanish — leave their pen every day to forage amongst the orchard trees, which are primarily citrus fruits. The turkeys are currently living at Xandari for aesthetic purposes, but the hope is that eventually they could also supply eggs or meat to the kitchen.

Winged Wildlife at Carara National Park (Part 2)

White Ibis on the banks of a river.

As I hinted in Part 1, Carara National Park is great for experiencing much of Costa Rica’s famous biodiversity. Monkeys, iguanas, poison dart frogs, and insects, together in a rich rainforest replete with all sorts of weird fungi that can look tasty and cute. Upon entering the park, James and I were greeted with the laughing calls of Black-hooded Antshrikes, birds that enjoy the columns of marching insects that commonly go by the name of “army ants.” Plenty of other birds with the word “ant” in their names made themselves known with their songs or movements in the undergrowth: male and female Dot-winged Antwrens, a Dusky Antbird, several Chestnut-backed Antbirds and Black-faced Antthrushes, and even a Streak-chested Antpitta heard from afar.

Apart from birds, we also saw several species of butterfly, including this one with the classic owl-eye pattern on its wings to startle potential predators. We also saw cicadas, but several times they had fallen prey to skillful salliers from silent perches. This female White-whiskered Puffbird, as well as this woodcreeper (Long-tailed, perhaps?), both emerged from their hidden leafy blinds to land somewhere with a juicy, shiny cicada in their beaks. There were several other woodcreepers doing their job–creeping along tree trunks–like a Streaked Woodcreeper with its powerful bill, and in general James and I struggled to Continue reading

Wildlife at Carara National Park: Part 1

Red-capped Manakin (male). He has spiffy yellow thighs, unfortunately not visible in this picture.

A few weekends ago, James and I spent six hours at Parque Nacional Carara, on the Pacific side of Costa Rica and just about an hour and a half from Xandari. Braving the muggy, humid coastal rainforest with the intention of spotting and/or hearing at least fifty new (for us) species, we set off on the first couple miles of trail with our field guide in hand. James uses a pair of Nikon Monarch binoculars for quick spotting and following birds as they flit around, and I sport a Canon SX50 digital camera to hopefully capture still images or video for identification purposes. Sometimes I get lucky enough to take a photo that’s worth sharing!

But not all the wildlife we spotted at Carara was avian. On the way to the park entrance, we crossed the famous Río Tarcoles, a river that is home to dozens of crocodiles that bask in the mud, particularly under the bridge that tourists walk over to gaze at the enormous predators hanging around. James and I saw plenty of smaller reptilian relatives skitter across the paths at the park, including iguanas and a basilisk lizard. We passed several troops of leaf-cutter ants marching  Continue reading
