Recently, I have been reading quite a bit about migration during the Early Medieval period.

It wasn’t until about 5 million years ago that modern camels first appeared, but they, along with primordial horses like that recently found in Oklahoma, remained on the ancient range well into the days of human habitation.

Our latest paper has been published a few days ago in Geomorphology. The title is: "The origin of oriented lakes: Evidence from the Bolivian Amazon". Here goes a very short version of it.The presence of hundreds of rectangular and oriented lakes is one of the most striking characteristics of the Llanos de Moxos landscape (Fig. 1). Many different mechanisms have been proposed for their formation, including subsidence resulting from the propagation of bedrock faults through the foreland sediments, scouring caused by large-scale flooding, paleo deflation combined with wind/wave action and human agency. Nevertheless, amid this diversity of hypothesis, the most commonly accepted cause of lake formation to date has been tectonics.Figure 1. Landsat image of oriented and rectangular lakes in the Llanos de MoxosPlafker’s tectonic model (Fig. 2) has never been tested. If faulting is involved, the displacement should be visible and measurable through sediment profiling. The only element needed is a stratigraphic marker that allows the measurement of the vertical displacement.Figure 2. Tectonic model for lake formation (Plafker, 1967). According to Plafker, the lakes' rectangular shape results from the propagation of bedrock fractures through unconsolidated sediments.Thanks to our recent discovery of a paleosol below mid-Holocene fluvial sediments in the south-eastern LM (Lombardo et al., 2012), where several lakes are found, it is now possible to test the tectonic hypothesis. If lakes were formed by local subsidence induced by bedrock faults, we should find the paleosol at a greater depth below the lake than in the area surrounding it. This is how we cored the lakesStratigraphic profiles from transects that cut across the borders of three lakes show otherwise (Fig. 3): the depth of the paleosol is the same. Hence, tectonics, as the mechanism behind the formation of the lakes, can be ruled out. The origin of the Moxos rectangular and oriented lakes is still very much unresolved. A more detailed discussion about the possible mechanisms behind the lakes' formation can be found in Lombardo & Veit (In Press). Figure 3. Stratigraphic transects from the outside to the inside of the lakes. Dotted white lines define the lakes’ basins. The early to mid-Holocene paleosol acts as a stratigraphic marker (see Fig. 2). Cores 52, 63, 81, 170, 205 and 210 provide the reference depth of the paleosol outside the lakes; cores 77 and 204 have been performed in areas of the original lakes’ basins that have been infilled; cores 78, 169, 171 and 209_b come from inside the lakes. Continuous black lines reconstruct the original lake bottom (previous to lacustrine infilling); dashed black lines connect the paleosol.

Before their daughters grow up and leave home, mothers may impart some lessons in the womanly arts—for example, the proper way to whoop and hoot with your mate while sitting in a tree branch. As an adult, a female gibbon sings elaborate duets with her male partner. But before she leaves the family, her mother seems to take responsibility for the daughter's vocal lessons.
Young gibbons spend many years learning to vocalize like adults. By age six or so, "sub-adult" apes can match the vocal prowess of a grownup. Mothers and daughters often sing at the same time, though it's not clear why. Researchers traveled into the rainforests of Sumatra to make audio recordings of gibbon families and try to figure out whether these sing-alongs are significant.
Lead author Hiroki Koda of Kyoto University and his colleagues studied six families of agile gibbons (that's a species name, not just a descriptor). Koda explains that gibbons are monogamous, and male and female young grow up with their parents before departing the group to find their own partners. Each family in the study included a nearly adult daughter, and the researchers captured recordings of these daughters and their mothers singing together.
They found that some daughter gibbons were better than others at singing in sync with their mothers. They were also better at matching their mothers' tunes. But these talented daughters actually duetted with their mothers less often. Koda thinks that's because the ones who "showed more skillful songs" are the most mature, and are nearly ready to leave home. Daughters who still need the practice sing with their mothers more often.
Here, a mother and daughter gibbon match each other's calls as they sing together:

The researchers also found that mothers who sing more often with their daughters—the ones who are still giving lessons—modify their own songs more when they do so. Koda says this may be similar to the "motherese" that humans speak to their babies. Like human moms talking slowly and at a high pitch, gibbon moms alter their vocalizations when duetting with their daughters.
Koda says that in the past, primate calls have been seen as "completely different from human language development." Rather than learning from their parents, young monkeys and apes seem to figure out their calls on their own. But this is the first evidence of mothers helping offspring learn to vocalize in gibbons—or any other nonhuman primate.
By paying more attention to vocal interactions between parents and offspring, Koda thinks scientists might discover other examples of primate parents getting involved in their children's learning. (After that, maybe they'll discover primate parents getting too involved. "Don't you take that tone with me, young lady! I heard what you just hooted!")

Hi Mia & Julie – Firstly, thanks so much for letting me drop a verse in the rap song of your blog! I feel so awesome being featured. It’s like being Lil Wayne or something. Anyway…I’m just recently back from ISAZ 2013, where I had a most excellent time chatting with other anthrozoologist-y types. As you know, I just graduated from the Anthrozoology Master’s Program at Canisius College, so I was uber-excited to have a chance to share my research with colleagues in the field. ISAZ did not disappoint. Pauleen Bennett & Heather at ISAZ 2013Now I get to share with you two and it just gets better and better! :-)My master’s thesis research project (advised by the oh-so-awesome Christy Hoffman) looked to answer the question: “Does Black Dog Syndrome Exist?”Animal welfare folks are probably familiar with the concept of Black Dog Syndrome (BDS) that Julie introduced last week: it’s the idea that dogs with black coats have a harder time than other dogs getting adopted, and as a result, may face higher rates of euthanasia and longer stays in adoption programs. Popular media - but is it correct?A lot of popular media articles focus on this concept (like here, here, here and here) but the research results have been mixed: in a study published earlier this year, participants rated an image of a black dog as significantly less agreeable, less conscientious, and less emotionally stable than a yellow dog (Fratkin & Baker, 2013). Yet research into factors influencing shelter dogs’ lengths of stay (LOS) found that LOS was not significantly correlated with coat color (Brown, Davidson, & Zuefle, 2013; Protopopova, Gilmour, Weiss, Shen, & Wynne, 2012).To dig deeper into the questions of whether potential adopters discriminate against black dogs in a shelter and whether black dog discrimination is reflected in shelter stats, I conducted a two-part research project: Shelter Visitor Pilot Study – examined interaction between potential adopters and shelter dogs Shelter Data Analysis Study – investigated relationships between LOS and coat color, age, sex and breed, as well as the impact of these variables on likelihood of euthanasiaAnd what I found may surprise you. There was very little evidence to support the concept of Black Dog Syndrome! From Heather's ISAZ 2013 posterI know animal shelter workers are going “WHAT!?” right now – I know because I AM a shelter worker – but the truth is, even if many potential adopters come to the shelter with a negative bias toward black dogs, it’s not resulting in crazy-long shelter stays or greater risk of euthanasia for black dogs. In fact, according to analysis of shelter statistics, black dogs were adopted out faster than average at both shelters in my study. Black dogs were also less likely than expected to be euthanized (good news for black dogs, eh?).When shelter visitors video-recorded their walk through the adoption area, I found that they spent about equal amounts of time looking at every dog, regardless of coat color. Visitors also rarely made specific comments with regards to coat color, although one guy did say: “I like black. Black dogs ... Read more »
