  2. PCG is always a great resource. ISN also created a bootbrush sign a while back, based on the NPS bootbrush stations; it's in the Downloads section here:
  3. I am on the hunt for a good invasive species awareness sign for terrestrial/upland habitats. What I am essentially hoping for is a Stop Aquatic Hitchhikers sign but for terrestrial circumstances. I haven't had much luck with a Google search and so far am leaning toward something from PlayCleanGo but thought I would put it out there to see if any Michigan-based folks have or have seen anything that might fit my search. Thanks in advance for any ideas!
  4. Researchers have assembled the first reference genome for the Nile rat -- a kind of genetic template of this species that may be used for laboratory and clinical studies. The hope is that it will be useful for those who investigate Type 2 diabetes and neurological disorders associated with a disrupted diurnal rhythm. The Nile rat is prone to diet-induced diabetes, and exhibits a clear diurnal pattern, unusual in rodents. View the full article
  5. A research group has created a successful donkey embryo using in-vitro fertilization (IVF), which could save dozens of endangered donkey species. View the full article
  6. Why are there more plant species in some places than in others? Why is diversity highest in the tropics? What is the connection between biodiversity and environmental conditions? To help answer these questions, an international team has reconstructed the distribution of plant diversity around the world and made high-resolution predictions of where and how many plant species there are. This will support conservation efforts, help to protect plant diversity and assess changes in the light of the ongoing biodiversity and climate crises. View the full article
  7. Plants need light to grow. However, due to excess nutrients and/or the absence of herbivores less light can reach lower vegetation layers in grasslands. Consequently, few fast-growing species dominate and plant diversity declines. So far, this relationship has been established indirectly through experiments, but never directly by means of experimentally adding light in the field. Now biologists have been able to experimentally demonstrate the dominant role of light competition. View the full article
  8. In the U.S. Geological Survey's Non-Indigenous Aquatic Species database, these so-called 'native transplant' fish are almost twice as common as fish introduced from outside the country. But a new review says native transplant fish, especially those that don't qualify as game fish, are rarely studied and their impacts poorly understood. View the full article
  9. The invasive spotted wing drosophila (SWD) is a well-known pest in agriculture. A recent study by Swiss scientists now shows that the forest ecosystem is also affected by this alien insect. SWD infests the fruits of various forest plants and competes with other fruit-eating species. The decay of fruits attacked by SWD leads to a loss of resources, which can cause considerable ecological damage. View the full article
  10. Invasive plants can have devastating effects on local ecologies, comparable to the effects wrought by global warming. And yet, there is currently no reliable understanding of how many invasive plant species there are in the world. New research comprehensively pinpoints the various unknowns that need to be addressed in order to intelligently manage invasive species around the world. View the full article
  11. A recent experiment provides evidence of a bark beetle species' agricultural capability. The fruit-tree pinhole borer can suppress the growth of weed fungi and promote food fungi. View the full article
  12. Researchers have published a comprehensive study on the significance of species differences for the most central cell maintenance mechanisms. The researchers used the brown hare (Lepus europaeus) and the mountain hare (Lepus timidus) as model organisms in their study. View the full article
  13. Communication is everything -- and that applies for algae, too. However, their chemical language and its significance in aquatic ecosystems remain largely unknown. New research summarizes the current state of knowledge and identifies new approaches for future research in the language of algae and their ecological relationships. View the full article
  14. New research conclusively shows that certain physical traits of flowers affect the health of bumble bees by modulating the transmission of a harmful pathogen called Crithidia bombi. In particular, the research shows that the length of a flower's corolla, or the flower's petals, affects how this pathogen gets transferred between bees because shorter corollas mean that fewer bee feces wind up inside the flower itself and in the path of the bees in search of nectar.

  15. NASA's Global Ecosystem Dynamics Investigation (GEDI) mission can provide valuable information about the world's forests for wildlife scientists. View the full article
  16. A study bu a conservation psychologist reveals overwhelming public ignorance of Australia's most threatened species, a factor that is contributing to the extinction crisis of endangered animals. View the full article
  17. Scientists conducted a 7-year study on seedling recruitment and mortality in a national park in Chiang Mai, in northern Thailand. During the study period, an extremely strong El Niño event occurred, leading to a stronger and longer drought than normal. Seasonally dry tropical forests (SDTFs), which experience an annual dry season, are considered drought-tolerant. Nevertheless, the study found that seedling mortality increased in SDTFs when severe and prolonged drought occurred. View the full article
  18. The efficient running of wastewater treatment plants is an essential part of modern society. Just like humans, wastewater treatment plants can get sick, due to viral attacks. Now, new research reveals the implications for the surrounding environment in case the plant catches a cold. From the study, the researchers have shown there is a clear relationship between virus concentration and the amount of dissolved organic carbon present in the effluent water. More of this carbon in the effluent water, means increased oxygen consumption in the surrounding bodies of water where the effluent is discharged. This could have potential negative impacts on the aquatic ecosystems nearby. View the full article
  19. Scientists have developed a method for the direct observation of fine roots, which control the uptake of nutrients and water by trees. This provides a valuable addition to the existing knowledge of carbon and nutrient cycling in the forest floor, leading to further understanding of the carbon cycle from the view point of initial carbon input into the soil and aiding forest management and soil conservation.

  20. Prescribed fire -- a tool increasingly used by forest managers and landowners to combat invasive species, improve wildlife habitat and restore ecosystem health -- also could play a role in reducing the abundance of ticks and the transmission of disease pathogens they carry, according to a team of scientists.

  21. A new study shows for the first time that carefully placed no-fishing zones can help to restore tunas and other large, iconic fish species. View the full article
  22. Researchers used artificial nests to test two methods for reducing the nest predation of vulnerable and endangered ground-nesting birds. The study showed that red foxes can be more easily deceived into not eating bird eggs than raccoon dogs. The methods could be used alongside hunting and offer an alternative, non-lethal solution for creating protection for vulnerable prey. View the full article
  23. A new article adds a new chapter to the story of how some animals may respond to the warming oceans. View the full article
  24. I am currently in the process of trying to come up with a treatment acreage goal for a grant I’m working on. I want to be sure that it is something that my invasive species strike team will be able to handle and that we will be able to accomplish the goals I set! Is there a good way to estimate or a general rule for how many acres per-person can be treated in a month/year? We only have a small team of two or three. How would team size and equipment type factor in? More importantly, am I overthinking this? Thanks for your help!
  25. Jacks and barracuda in He?eia fishpond were found to feed on Australian mullet, an invasive species introduced to Oahu waters in the 1950s. This recently published finding suggests that these native predatory fish may provide a form of biocontrol on populations of the invasive mullet species in a traditional Hawaiian fishpond.
