“Research” seems to be branch node, with live links only on the leaves, “Projects”, “Our Reports”, and “UC Olive Database". Which is a website fail, sure, but since the leaves are on the page navigation, not one that stops you from getting to the data (and since “Research” isn't a link on the nav bar, just a label, the only way to get to the broken page seems to be following breadcrumbs from one of the leaves.)
