- Andrew A. Olkowski added an answer:18PLOS ONE, PeerJ or conventional journals for publication? - suggestions for early career professionalsPLOS ONE, PeerJ and other open access peer reviewed journals are coming as the best alternative academic publications to the conventional journals. There is debate going on which one is better, the image of IMPACT FACTOR is also controversial. What are your thoughts for the early career professionals to publish on the emerging open access journals like PLOS ONE and PeerJ?
Generally, I do not publish my papers in Journals that charge the authors $$ for publication. However, for a very specific reason, last year I submitted my manuscript to PEERJ with understanding that the cost of publication will be $99. Shortly after the submission, each co-author was contacted by PJ, with invoice demanding payment from every co-author. I asked the editorial office to explain this, and it turned out that this is indeed PJ policy, which is buried deeply in legal jargon somewhere in the fine print. In the end, I decided to withdraw our manuscript, and will never send my work to PJ again. Indeed, PEERJ is widely advertising the cost of publication capped at $99, but in reality this is not the case.Following
- Julian D. Reynolds added an answer:31How can we prevent the invasive Signal crayfish from entering Ireland and devastating the last large populations of White-Clawed crayfish?Signal Crayfish from the western US were introduced to Sweden and later to England for aquaculture, but they quickly established themselves in rivers and lakes. The species are now present across Europe, with the exception of Ireland. It reaches high densities, is easily trappable, and fetches high prices at market, but it carries an oomycete parasite lethal to non-American crayfish, and its establishment has been followed by the demise of native species and alteration of ecosystems. In Britain it has been shown to damage river banks and reduce recruitment of wild salmonids. The ecological damage is unquestionable, but the desire of people to introduce a new quarry species seems insatiable, despite legislation in place to restrict introductions. Once in Ireland, it is probably too late to do anything about them; trapping has not proven effective to control signals.
Thank you everyone for contributing. This problem is ongoing, and this summer we have had a crayfish plague outbreak, the first in 30 years. The plague type is associated with signal crayfish, but so far, thankfully, no signal crayfish have been found, leading to the possibility that the oomycete was brought in accidentally. There is a good chance that the outbreak will burn itself out, with the loss of substantial regional stocks, but if signals are confirmed, the widespread Irish stocks of white-clawed crayfish are likely to follow those in UK, France, Spain, Italy etc. into near-extinction.Following

- Jürgen Gross added an answer:12How to mange the Human Elephant Conflict in Human dominated landscape?Every year about a dozen people are killed by wild elephants in Nepal, mostly by the solitary bulls and the conflict is increasing every year. There are a few retaliatory killings of the elephants also in recent years. Most of the elephant habitat is fragmented and there is a high pressure of resource extraction in the remaining forest patches outside protected areas. In such situation, what are the best practices around the world to manage such a conflict?
In agricultural areas with high abundance of large herbivores, especially elephants, new approaches to crop protection are needed. The IUCN Red List ranks human-elephant conflicts as one of the three major threats to the species survival. The selection of appropriate, less attractive or even unpalatable crops is an important step to tackle these conflicts. If the pachyderms do not find nutritious and attractive crops on the farms in their home range, reduction of crop losses is very likely. To foster this approach however, more detailed studies are needed, to observe the resistance of the crops in long-term and to identify a larger diversity of unattractive crops. Given a good market access these crops should serve both, people and threatened wildlife species.
We recently published a research paper on a field experiment which was conducted by Awely and the SLCS in Zambia. We could show that cultivating alternative crops (ginger, garlic, lemon grass) containing allelochemicals which may unattractive or even repellent to elephants, reduces crop losses due to African elephants in South Luangwa, Zambia. The selection of crops which are less attractive, deterrent or repellent to large herbivores needs to be considered as a strategy to reduce conflicts between farmers and endangered wildlife species.

- Franklin M M White added an answer:19Monarch butterfly numbers drop to lowest level since records started: what can be done about this?This concern was promoted in an article in the Guardian newspaper (Wednesday 29 January 2014) : According to this article, the number of Monarch butterflies (Danaus plexippus) wintering in Mexico plunged this year to its lowest level since studies began in 1993, leading experts to announce Wednesday that the insects’ annual migration from the United States and Canada is in danger of disappearing. A study (cited below) released by the World Wildlife Fund, Mexico’s Environment Department and the Natural Protected Areas Commission blames the displacement of the milkweed the species feeds on by genetically modified crops and urban sprawl in the United States, as well as the dramatic reduction of the butterflies’ habitat in Mexico due to illegal logging of the trees they depend on for shelter. What can be done about this? Reference: OMAR VIDAL, JOSÉ LÓPEZ-GARCÍA, EDUARDO RENDÓN-SALINAS. Trends in Deforestation and Forest Degradation after a Decade of Monitoring in the Monarch Butterfly Biosphere Reserve in Mexico. Conservation Biology (2014) 28; 1: 177–186.
The following report is extracted verbatim from Bird Studies Canada Latest News - 7 August 2015 <email@example.com<firstname.lastname@example.org>:
"5 August 2015 – Monarch butterfly populations have declined steadily at overwintering sites in Mexico over the last 20 years. Little is known about what’s causing the declines, and whether declines are also occurring across North American breeding grounds, and during southbound migration to Mexico each fall.
This week, seven monarch studies were published in the Annals of the Entomological Society of America <http://aesa.oxfordjournals.org/monarch_collection>. The articles examine population trends using data collected by Citizen Scientists. Included in this series is a paper by Dr. Tara Crewe and Jon McCracken of Bird Studies Canada, examining long-term trends in monarch numbers counted migrating through Long Point, Ontario from 1995-2014. Monarchs were counted daily during fall migration by Long Point Bird Observatory volunteers. The results suggest that the number of monarchs migrating through Long Point has declined by up to 7.8% per year since 1995."

- Eugenia López López added an answer:4Fish species distribution?I have two questions regarding fish biodiversity.
Q1. What does it mean if you have a large or small number of families with only one or two species in each of them?
Q2. What does it mean if you have a large or small number of families with large number of species?
Do these changes have something to do with the evolution of the families in the area?
It depends on the biogeographic history of the study area (lake or river, basin etcc). In some cases the study site could be a center of speciation and several speceies of one family could be the result. (i.e. The Mexican Central Plataeu have Goodeids as an endemic family of fish with more than 50 species). But also, the number of species of a same family could be resulted of biological interactions obetween fish of the study site, Some species of the same family use similar resources and can exert competitive displacement.Following

STRUCTURE uses assignment methods to cluster individuals according to their genetic similarity. It can be used to study the genetic structure of a group of populations, or between different hybridizing species. For example, it gives an idea of which populations are more connected through gene flow and which ones are more divergent. If it is used together with other analyses such as PCA, can be very useful for population genetics.Following

I am expecting your constructive idea and parameters which I should consider during field work to address the following points.
We will establish a biodiversity experiment, which analyzes the influence of human impact on canopy flora and fauna.
• Forests of different human impact (national park vs managed forest) will be compared.
• The influence of collection of certain epiphyte groups on the ecosystem functioning of canopy communities will be analyzed by removal of one epiphyte taxon.
• Most important: Epiphytes and arthropods will be analyzed on the same trees, so that their interrelationships can be studied.
Based on our results we will develop guidelines for sustainable forest management and canopy biodiversity conservation.

Great discuss, I have few thoughts to natural history. First - it was my interest to study animals in their environment. This is a key point why I have studied Protection and Exploitation of Nature and Landscape. But back to question - I think that it depends on departments, respective if it is biology, molecular biology, ecology, conservation biology...My opinion is that natural history is fundamental discipline for conservation biologists, ecologists and biologists. Because these people work regulary in the field. And also they can work in non-research sector - like for NGOs - where there are these skills very useful and demanded.Following
