  1. I noticed this article a while ago , drowning plants in a dam creates problems with their decay Collectively, reservoirs created by dams are thought to be an important source of greenhouse gases (GHGs) to the atmosphere. So far, efforts to quantify, model, and manage these emissions have been limited by data availability and inconsistencies in methodological approach. Here, we synthesize reservoir CH4, CO2, and N2O emission data with three main objectives: (1) to generate a global estimate of GHG emissions from reservoirs, (2) to identify the best predictors of these emissions, and (3) to consider the effect of methodology on emission estimates.
  2. This study looks at a number of interesting things
  3. Orphaned female elephant social bonds reflect lack of access to mature adults Shifra Z. Goldenberg & George Wittemyer Scientific Reports 31 Oct 2017 LINKS TO FULL PAPER: Abstract: Compensatory social behavior in nonhuman animals following maternal loss has been documented, but understanding of how orphans allocate bonding to reconstruct their social networks is limited. Successful social integration may be critical to survival and reproduction for highly social species and, therefore, may be tied to population persistence. We examined the social partners involved in affiliative interactions of female orphans and non-orphans in an elephant population in Samburu, northern Kenya that experienced heightened adult mortality driven by drought and intense ivory poaching. We contrasted partners across different competitive contexts to gain insight to the influence of resource availability on social interactions. Though the number of partners did not differ between orphans and non-orphans, their types of social partners did. Orphans interacted with sisters and matriarchs less while feeding than did non-orphans, but otherwise their affiliates were similar. While resting under spatially concentrated shade, orphans had markedly less access to mature adults but affiliated instead with sisters, bulls, and age mates. Orphan propensity to strengthen bonds with non-dominant animals appears to offer routes to social integration following maternal loss, but lack of interaction with adult females suggests orphans may experience decreased resource access and associated fitness costs in this matriarchal society.
  4. The Alliance of World Scientists is a new international assembly of scientists, which is independent of both governmental and non-governmental organizations and corporations. We submit, that in order to prevent widespread misery caused by catastrophic damage to the biosphere, humanity must practice more environmentally sustainable alternative to business-as-usual. Our vital importance and role comes from scientists' unique responsibility as stewards of human knowledge and champions of evidence-based decision-making. please see they have warned that the world's environment and its capacity to support human life is seriously declining any scientists here are welcome to join the over 15,000 scientists who have already endorsed the statement this follows a 1992 statement from the union of concerned scientists in the years inbetween the only thing to improve is the condition of the ozone layer

  6. This is very interesting Lemurs eat way less fruit than most other primates, and scientists have a new hypothesis as to why: the fruit on Madagascar, where the lemurs live, is unusually low in protein. Scientists posit that the evolution of unusual dietary behaviors in lemurs, from leaf-eating to hibernating, is tied to fruit quality. 1. Giuseppe Donati, Luca Santini, Timothy M. Eppley, Summer J.

  10. PEER J published the great elephant census report so I put myself on their email list this came from them recently quoting briefly a popular report Caribou are facing a lot of threats. On top of hunting and habitat destruction, invasive species play a large role in the caribou's decline, according to Robert Serrouya, a professor in the Department of Biological Sciences at the University of Alberta. Managing these species, including moose and white-tailed deer, could also be the key to stabilizing the caribou population, according to his new study published in PeerJ. in it there was a link to another story and a SCIENCE ADVANCES article
  11. study of museum specimens of the spine of both woolly and modern rhinos gives rise to concern the cervical rib is absent this is often associated with inbreeding and adverse environmental conditions during pregnancy it has been recently found that mammoths had a rate of this condition 10 times greater than modern elephants the team considers that this could been connected to the extinction of both species there is also concern about the lack of diversity in modern rhinos , and it is recommended that their spines be monitored

  19. After observing the mating habits of chacma baboons living in the wild over a four-year period, researchers have found that males of the species often use long-term sexual intimidation to control their mates. The findings suggest that this mating strategy has a long history in primates, including humans, and may be widespread across social mammals -- especially when males of a species are typically larger than females. press release continues . for the article

  24. New research reveals that a species of giant elephant that lived 1.5 million to 100,000 years ago -- ranging across Eurasia before it went extinct -- is more closely related to today's African forest elephant than the forest elephant is to its nearest living relative, the African savanna elephant. The study challenges a long-held assumption among paleontologists that the extinct giant, Palaeoloxodon antiquus, was most closely related to the Asian elephant. The findings, reported in the journal eLife, also add to the evidence that today's African elephants belong to two distinct species, not one, as was once assumed.
